The document proposes a framework that uses weblogs, digital libraries, and semantic web services to improve knowledge management and productivity for engineers during design projects. It discusses how weblogs can facilitate knowledge sharing and socialization among engineers, and how digital libraries can serve as a centralized knowledge base. It also introduces semantic web services to help integrate and utilize scattered computing resources for automated analysis. The framework aims to address common obstacles engineers face regarding limited access to relevant knowledge and convenient tools. An example social-web system prototype is presented to illustrate how the proposed technologies can be combined into a knowledge management system.

As organizations invest more and more into advanced automation, we are seeing significant advancements in Artificial Intelligence (AI) in the business world. The rise of the machines is becoming an impending reality. The AI revolution is here. Most businesses are aware of this and see the tremendous potential of AI. In fact, the largest tech companies and governments are all heavily investing in AI research.
The most common type of AI is currently still Machine Learning (ML), which leverages statistical techniques to give computer systems the ability to learn with data, without being explicitly programmed.
This presentation specifically discusses a specific type of ML called Deep Learning. Deep Learning uses computers to create networks which simulate the way a human brain perceives, organizes, and makes decisions from data input.
This presentation further explores the most widely used models of Deep Learning in the business world:
1. Convolutional Neural Network (CNN)
2. Recurrent Neural Network (RNN)
Examples of Deep Learning being used include:
* Processing handwritten material
* Diagnosing health diseases from medical scans
* Using radar imagery to help guide self-driving cars
* Generating captions to images
* Assessing the likelihood that a credit card transaction is fraudulent
* etc.
This deck also includes slide templates for you to use in your own business presentations.

Web Mining Based Framework for Ontology Learningcsandit
Today, the notion of Semantic Web has emerged as a prominent solution to the problem oforganizing the immense information provided by World Wide Web, and its focus on supporting
a better co-operation between humans and machines is noteworthy. Ontology forms the major
component of Semantic Web in its realization. However, manual method of ontology
construction is time-consuming, costly, error-prone and inflexible to change and in addition, it requires a complete participation of knowledge engineer or domain expert. To address this
issue, researchers hoped that a semi-automatic or automatic process would result in faster and
better ontology construction and enrichment. Ontology learning has become recently a major
area of research, whose goal is to facilitate construction of ontologies, which reduces the effort
in developing ontology for a new domain. However, there are few research studies that attempt
to construct ontology from semi-structured Web pages. In this paper, we present a complete
framework for ontology learning that facilitates the semi-automation of constructing and
enriching web site ontology from semi structured Web pages. The proposed framework employs
Web Content Mining and Web Usage mining in extracting conceptual relationship from Web.
The main idea behind this concept was to incorporate the web author's ideas as well as web
users’ intentions in the ontology development and its evolution.

We propose that one of the barriers to OER adoption is the lack of transparency of practitioners’ ‘thinking’ around OERs.Threfore we propose to move from opening up contents and OER to opening people’s thinking about OERs.
Our objective is to make this thinking visible and exportable in a way that support the emergence of collective intelligence around OER. To cater for this we designed Cohere, a prototype socio-technical infrastructure to gather Collective Intelligence around OER.
The Use of Social Media to Gather Qualitative Data: A Case of Government E-P...IAIN Datokarama Palu
The emergence of social media is enabling researchers to consider new data collection and triangulation strategies. Quantitative researchers have taken advantage of the emergence of the Internet as a medium to gather data. Meanwhile, interpretive researchers are only now being able to harness the potential that social media provide in generating more insight into collected data. Using a case of government e-procurement implementation and use in an Indonesian regency, we illustrate how social media exchange, postings, and conversations can be used as a source of rich qualitative data to enhance understanding of a topic being studied. Our findings show that monitoring social media exchange, postings, and conversation can strengthen our understanding and interpretation of offline data (such as interviews). This study contributes to literature on the use of online media for interpretive data collection.

"Smart Content: The Importance of Semantics in Publishing"
The way we organize our information is shifting from the book-centric table of contents or bibliographic citations to a more dynamic approach that directs us to content that may never have been initially intended, or previously encountered.
Smart content is content that is equipped with structured data that allows it to soar across domains, user groups, profiles, and knowledge maps to reach readers in non-linear ways. Through the guidance of taxonomies and the exploitation of classifications, smart content no longer waits for the wisdom of the reader, but seeks the most appropriate reader for its content.
This presentation explores how semantics and reliable metadata act as agents to broker such relationships.
NLP-based personal learning assistant for school education IJECEIAES
Computer-based knowledge and computation systems are becoming major sources of leverage for multiple industry segments. Hence, educational systems and learning processes across the world are on the cusp of a major digital transformation. This paper seeks to explore the concept of an artificial intelligence and natural language processing (NLP) based intelligent tutoring system (ITS) in the context of computer education in primary and secondary schools. One of the components of an ITS is a learning assistant, which can enable students to seek assistance as and when they need, wherever they are. As part of this research, a pilot prototype chatbot was developed, to serve as a learning assistant for the subject Scratch (Scratch is a graphical utility used to teach school children the concepts of programming). By the use of an open source natural language understanding (NLU) or NLP library, and a slackbased UI, student queries were input to the chatbot, to get the sought explanation as the answer. Through a two-stage testing process, the chatbot’s NLP extraction and information retrieval performance were evaluated. The testing results showed that the ontology modelling for such a learning assistant was done relatively accurately, and shows its potential to be pursued as a cloud-based solution in future.

Riley, Jenn. “How Much to Semanticize? Looking at the future of Library Data and the Semantic Web.” University of Illinois at Urbana Champaign Library Colloquium Series, April 21, 2010.
The diversity and complexity of contents available on the web have dramatically increased in recent years. Multimedia content such as images, videos, maps, voice recordings has been published more often than before. Document genres have also been diversified, for instance, news, blogs, FAQs, wiki. These diversified information sources are often dealt with in a separated way. For example, in web search, users have to switch between search verticals to access different sources. Recently, there has been a growing interest in finding effective ways to aggregate these information sources so that to hide the complexity of the information spaces to users searching for relevant information. For example, so-called aggregated search investigated by the major search engine companies will provide search results from several sources in a single result page. Aggregation itself is not a new paradigm; for instance, aggregate operators are common in database technology.
This talk presents the challenges faced by the like of web search engines and digital libraries in providing the means to aggregate information from several and complex information spaces in a way that helps users in their information seeking tasks. It also discusses how other disciplines including databases, artificial intelligence, and cognitive science can be brought into building effective and efficient aggregated search systems.
This paper introduces the concepts of Hypermedia and Hypertext systems as tools for managing information in the field of architecture and enhancing the landscape of education. An application developed by the author is used to illustrate the use of Hypertext programs in architectural education. Paradox, a powerful relational database program, is used to develop an application illustrating the works and philosophies of twentieth century masters of architecture. The paper recommends the development of similar applications to be available for students through computer networks, as tools for managing growing amounts of information and enhancing the landscape of learning.
An efficient educational data mining approach to support e-learningVenu Madhav
The e-learning is a recent development that has
emerged in the educational system due to the growth of the
information technology. The common challenges involved
in The e-learning platform include the collection and
annotation of the learning materials, organization of the
knowledge in a useful way, the retrieval and discovery of
the useful learning materials from the knowledge space in a
more significant way, and the delivery of the adaptive and
personalized learning materials. In order to handle these
challenges, the proposed system is developed using five
different steps of knowledge input such as the annotation of
the learning materials, creation of knowledge space,
indexing of learning materials using the multi-dimensional
knowledge and XML structure to generate a knowledge
grid and the retrieval of learning materials performed by
matching the user query with the indexed database and
ontology. The process is carried out in two modules such as
the server module and client module. The proposed
approach is evaluated using various parameters such as the
precision, recall and F-measure. Comprehensive results are
achieved by varying the keywords, number of documents
and the K-size. The proposed approach has yielded
excellent results by obtaining the higher evaluation metric,
together with an average precision of 0.81, average
Blockchain Architecture to Higher Education Systems de Palanivel Kuppusamy del Department of Computer Science de la Pondicherry University.
ABSTRACT:
The blockchain is an emerging technology that serves as an immutable ledger, which allows transactions to take place in a decentralized manner. It has become a publicly available infrastructure for building decentralized applications and achieving interoperability. Blockchain-based applications ensure transparency and trust between all parties involved in the interaction. The blockchain also makes blockchain technology-based services interest to the education sector. Nowadays, educational organizations focus on online education and propose to create a system based on educational smart contracts in a public ledger. This public ledger will be shared between major offline educational institutes around the world. From a software architecture perspective, blockchain enables new forms of distributed software architectures across a large network of untrusted participants. The objective of this article is to apply blockchain technology in learning solutions and to propose a blockchain architecture to e-Learning solutions in Higher Education Systems. The proposed architecture exploits the benefits of the blockchain and offering security, anonymity, longevity, integrity, transparency, immutability and global ecosystem simplification, in order to create a globally trusted higher education credit system.
The present society is considered an information society. A society where the creation, distribution, use, integration, and manipulation of digital information have become the most significant activity in all aspects. Information is producing from every sector of any society, which has resulted in an information explosion. Modern technologies are also having a huge impact. So managing this voluminous information is really a tough job. Again WWW has opened the door to connect anyone or anything within a fraction of a second. This study discussed the Semantic Web and linked data technologies and their effect and application to libraries for the handling of various types of resources.

At present, the state-of-the-art supplies for conducting a face-to-face design thinking workshop typically consists of self-stick notes and stickers, markers, and whiteboards. However, this analog way of working is incongruent with the realities of global software companies, where most products and services are developed by distributed teams. This paper explores the process of facilitating remote design thinking workshops, using information technology and communication tools. The paper is based on a participatory action research undertaken by the author as a part of the doctoral thesis - ‘a study on an approach to prepare the organization mindset to build design-led innovation culture to become a customer-centric and future driven software company’ in the Indian IT sector. The participating company realized the innovation breakthroughs using design thinking can happen only when their organization can collaborate across disciplines, silos, time zones; and were looking for a solution to scale design thinking in their organization.

Abstract: Social networks offer incredible opportunities for users to create contents and share their experiences. The number of users joining these social networks has been rising dramatically. However, in a social network several users may share the same name. This causes name ambiguity in which search engine returns homogeneous search results for each queried name. To solve this problem we propose an approach to improve search results for finding friends within a large social network by using friendships among users as our backbone feature. Our approach finds most ranked seeds by using PageRank algorithm before computing approximate shortest path in a directed graph. We also retrieve real data from the social network Twitter to verify our approach. Results show that our approach outperforms the SeedBase approach which selects seeds randomly with large margin.

Abstract: Practicing structural engineers are often faced with limitations in available computing tools as well as insufficient access to relevant knowledge for design projects and engineering jobs. At the launch of a project the immediate tasks invariably involve research, discussions with colleagues and a series of computations. These tasks are repeated over and over again until a final design is arrived at. The degree to which these tasks are well facilitated in an engineering firm helps determine the productivity of its engineers and thus the firm’s competitiveness in the industry. Semantic computing technologies such as Semantic Web Services, Weblog, and Dig-ital Library have substantial, hitherto untapped potential to improve the productivity of structural engineers. This dissertation proposes a support system for structural engineering using these semantic computing technologies. A system architecture and the key software components for it are specified and prototype systems presented. The support system involves two frameworks of software infrastructure: first, the Weblog and Digital Library Framework for Engineering Knowledge Management (Blog+DL), which uses Weblogs and Digital Libraries as core components of a collaborative structural engineering support system; second, the Semantic Web Services Framework for Computational Mechanics (SWSCM), a methodology that unifies and utilizes scattered computing resources. Blog+DL and SWSCM are complementary methodologies in the engineering process. Blog+DL relies on SWSCM to integrate computing resources shared by several parties. SWSCM can use Blog+DL to deploy and discover shared computing resources, as well as to educate and exchange knowledge, including peer opinions about underlying theories and user experiences. Two proof of concept prototype systems were developed. The first system illustrates the joint application of Blog+DL and SWSCM to build support systems that facilitate the computationally oriented knowledge management process in structural engineering. The second system illustrates the full potential of SWSCM to facilitate a computationally intensive workflow that involves heterogeneous engineering software components. Blog+DL and SWSCM combine semantic computing technologies to build computer-aided engineering tools that improve the productivity of individual engineers and thereby enhance the competitiveness of engineering firms.

Abstract: The element-free Galerkin method (EFGM) is a recently developed numerical technique for solving problems in a wide range of application areas including solid and fluid mechanics. The primary benefit of these methods is the elimination of the need for meshing (or remeshing) complex three-dimensional problem domains. With EFGM, the discrete model of the object is completely described by nodes and a description of the problem domain boundary. However, the elimination of meshing difficulties does not come freely since the EFGM is much more computationally expensive than the finite element method (FEM), especially for three-dimensional and non-linear applications. Parallel processing has long been an available technique to improve the performance of scientific computing programs, including the finite element method. With efficient programming, parallel processing can overcome the high computing time that is typically required in analyses employing EFGM or other meshless methods. This work focuses on the application of the concepts in parallel processing to EFGM analyses, particularly in the formulation of the stiffness matrix, the assembly of the system of discrete equations, and the solution for nodal unknowns, so that the time required for EFGM analyses is reduced. Several low-cost personal computers are joined together to form a parallel computer with the potential for raw computing power comparable to that of the fastest serial computers. The processors communicate via a local high-speed network using the Message Passing Interface (MPI), a standard library of functions that enables parallel programs to be executed on and communicate efficiently over a variety of machines. To provide a comparison between the parallelized and the serial versions of the EFGM computer program, several benchmark 3D structural mechanics problems are analyzed to show that the parallelized EFGM program can provide substantially shorter run time than the serial program without loss of solution accuracy.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

1. INTRODUCTION
Practicing engineers often face two obstacles during the course of a design project. One is the limited access to relevant
knowledge and another is the limited access to convenient computing tools. Many tasks are involved when a project is
launched, in terms of computing workflow, research work, and discussion among colleagues. These tasks are usually
repeated over and over again until a final design is arrived. If the tasks are not well facilitated, several bottlenecks will
occur and an engineering firm may lose its competitiveness in the industry.
Weblog, Digital Library, and Semantic Web Services possess the potential to improve the productivity of the
engineers in dealing with the computational and knowledge management workflows. Weblog (a.k.a. Blog) and Digital
Library†, modern information technologies deployable on the Internet or an intranet, can be combined into a modern form
of knowledge management (KM) system which more naturally and collaboratively facilitates individuals in sharing tacit
and explicit knowledge, as well as computing tools. Semantic Web Services, the joint application of the Internet-based
Web Services and the Semantic Web technologies, can also be integrated into the KM system to assist engineers in
sharing the wealth of computational tools that they have developed or possessed on the network of heterogeneous
computing platforms.
An overview of the knowledge management theories and information technologies essential to the application of
Weblog, Digital Library, and Semantic Web Services to improve the productivity of the engineers is presented in this
paper, and a framework for such an application is proposed. First, background information on knowledge management, as

2. well as the Theory of Organizational Knowledge Management, which is central to the development of the framework, is
presented. Second, Weblog and Digital Library, the modern information technologies that can be combined to build a
second generation KM system, are discussed. Next, Blog+DL, a framework for the joint application of Weblog and
Digital Library in engineering knowledge management, is proposed. To enhance Blog+DL in handling the computational
aspect of a design project, Semantic Web Services and the Semantic Web Services Framework for Computational
Mechanics (SWSCM), which address how computing software developed by heterogeneous group of people for different
computer platforms can be shared and interoperate on the Internet or an intranet, are introduced. Finally, a social-Web
system prototype, developed to assist users in building up the personal portfolios of knowledge and computing tools
which can be shared with their peers to form a larger organizational KM system, is presented to illustrate the framework.
2. KNOWLEDGE MANAGEMENT
2.1 General
Knowledge management (KM) is a process for optimizing the effective application of intellectual assets to achieve
organizational objectives (Pollock, 2001). Knowledges, the sets of processed information in relevant context ready for
understanding and actions (Turban and Aronson, 2001, as cited in Mezher et al. 2005), are organization-specific resources
that are indispensable to create values for the organization (de Geytere, 2007). Knowledge can be classified into two kinds,
namely, explicit knowledge and tacit knowledge. Explicit knowledge can be articulated in formal language such as
grammatical statements, mathematical expressions, and manuals, which can easily be processed by a computer. Tacit
knowledge on the other hand comprises personal knowledge embedded in individual experience, which are difficult to
articulate with formal language. Since a large portion of human knowledge resides in the form of tacit knowledge, tacit
knowledge is regarded as the more important kind of knowledge (Nonaka and Takeuchi, 1995).
2.2 Theory of Organizational Knowledge Creation
Knowledge is dynamic in nature. Nonaka and Takeuchi (1995) proposed the Theory of Organizational Knowledge
Creation which explains the creation of human knowledge through social interaction between tacit knowledge and
explicit knowledge by four temporal modes of knowledge conversion, namely, (1) socialization from tacit knowledge to
tacit knowledge, (2) externalization from tacit knowledge to explicit knowledge, (3) combination from explicit
knowledge to explicit knowledge, and (4) internalization from explicit to tacit knowledge.
Socialization, the process of “sharing experiences and thereby creating tacit knowledge” such as shared mental
models and technical skills, helps an individual to acquire tacit knowledge directly from others through observation,
imitation, and practice. Externalization, the process of “articulating tacit knowledge into explicit concepts,” is the
definitive process through which an individual attempts to conceptualize a mental image linguistically. Combination, the
process of “systemizing concepts into a knowledge system,” involves “networking” different bodies of explicit
knowledge in media such as documents or computerized communication channels so that they are “crystallized” into a
new knowledge. Internalization, the process of “embodying explicit knowledge into tacit knowledge,” is the process
through which experiences of the individuals, obtained through socialization, externalization, and combination, are
internalized into their tacit knowledge bases in the form of shared mental models or technical know-how. A knowledge
conversion is a social process between individuals and human cognition is an individual’s deductive process; therefore,
through shifts between these social knowledge conversion processes, the quality and quantity of tacit and explicit
knowledge are constantly “amplified.” The four temporal modes of knowledge conversion constitute the “knowledge
spiral” that drives the innovation of the organization (Figure 1). The knowledge creation model based on the theory of
organizational knowledge creation is sometimes called the SECI model (de Geytere, 2007).
3. WEBLOG AND DIGITAL LIBRARY
Many KM initiatives and tools for engineering design firms are available in the literature, cf. Al-Ghassani et al. (2005);
Carillo and Chinowsky (2006); Jonathan Cohen & Associates (2004); and Mezher et al. (2005). Most of them however
rely on proprietary technologies and do not conform to Internet standards other than the prevalent HTTP and HTML for
Web publication. Cross-system interoperability and advanced application of Web technologies, such as Semantic Web
(Berners-Lee et al., 2001) and Web feeds (Wikipedia, 2007d), therefore, cannot be achieved without major modifications
to the systems. In this section, Weblog and Digital Library, modern Internet technologies which overcome these
difficulties and can be integrated as part of a knowledge management tool, are presented.
3. 3.1 Weblog
A weblog, or a blog, is a Web-based journal publication which consists primarily of periodic articles, normally in reverse
chronological order (Wikipedia, 2007a). Each article in a blog is called a blog entry. A person who publishes to a blog is
called a blogger. To publish to a blog is called to blog, the gerund form of which is blogging. The totality of all blogs on
the Internet is called the blogosphere (Crystal, 2006; Wikipedia, 2007b).
A blog entry usually consists of (1) the title, (2) the content, (3) the categories, tag names, or keywords of the
content, (4) the date and time of publication, (5) the comment section where readers and the blogger can discuss and
exchange experiences and opinions about issues raised in the blog entry, and (5) the trackback (Trott and Trott, 2002)
hyperlink where the readers who blog about the blog entry can notify the original blogger about the existence and the
content of theirs. Hyperlinks, comments, trackbacks, and citations among blogs create online social networks and
promote the externalization, socialization, and combination of knowledge among the bloggers, according to the SECI
model.
Blogging is as easy as composing an e-mail. A blogger can blog about anything, ranging from news items, personal
opinions, pictures, hobbies, problems at work, to random thoughts. A blog entry usually contains some hyperlinks to other
Web documents which are the subjects of discussion. To publish a blog entry, a blogger logs on to his account on the blog
service provider Website, cf. Blogger (2007) and WordPress (2007), clicks the compose button, types the content into a
Web form, enters the title and keywords for the content, and clicks the publish button. The blog entry is instantly
published to the Internet and can be accessed by friends, colleagues, and the public through regular Web browsers, Web
search engines, and dedicated blog reader software that conforms to the Really Simple Syndication (RSS) (RSS Advisory
Board, 2006) or Atom (Nottingham and Sayre, 2005) Web syndication standards. A blogger can also send e-mails to a
secret e-mail address to publish the contents and picture attachments directly from an e-mail client software on a laptop
computer or a mobile phone. Blogging thus allows people to share information on the Internet with very little barrier.
Technorati, Inc., a major Web tracking company, reported that as of April 2007 there are 70 millions blogs on the Internet,
with 120,000 new blogs each day, and 1.5 million posts per day. The blogosphere grew from 35 to 70 million blogs in 320
days. Japanese, English, Chinese, and Italian are the four major blogging languages—37 percents of the blogs are in
Japanese, 33 percents in English, 8 percents in Chinese, and 3 percents in Italian (Sifry, 2007).
3.2 Digital Library
A digital library is an integrated set of services for capturing, cataloging, storing, searching, protecting, and retrieving
information (Reddy et al., 1999). It comprises the focused collections of digital objects, including text, video, and audio,
along with methods for access and retrieval, and for selection, organization, and maintenance of the collections (Witten
and Bainbridge, 2003) all of which to support life-long learning, research, scholarly communication and preservation
(Wikipedia, 2007c). Digital library was originally used to archive the digitized copies of rare documents, books, and the
pictures of historical objects so that they can be studied by people of later generations. It has also recently been used as the
central repository to preserve the works of individuals in an organization so that they do not vanish with time and
technological obsolescence (DSpace, 2007b).
A digital library system is often developed such that it is accessible on the Web, with the user interface resembling
that of a Website. However, not all Websites, even the ones that offer focused collections of well-organized material and
appropriate methods of access and retrieval, can be regarded as digital libraries, unless metadata (data about data), which
are the most important information to precisely catalog, locate and retrieve pieces of information, are stored along with
each object in the collections, and the access, retrieval, and modification of metadata, as well as the retrieval of objects
based on them, are facilitated by the system (Witten and Bainbridge, 2003). The metadata typically used in digital
libraries include bibliographic information and subject keywords, which are also used in physical libraries.
The users of a digital library system involve two roles, namely, the publisher and the reader. In some digital library
implementations, such as the Greenstone Digital Library software (Witten et al., 2006), a librarian takes the sole publisher
role to capture (e.g., by scanning printed articles or typing in a word-processor), create cataloging metadata, store,
manage, and publish the collections of digital objects; and the general users take the reader role to browse, search, and
consume information in the collections. In other digital library implementations, such as DSpace (MIT Libraries and
Hewlett-Packard Company, 2007) which is based on the institutional repository concept, select users may also publish to
some collections in the repository, thus taking both the publisher and the reader roles. Computers and users can locate
objects across heterogeneous digital library systems by using standard query protocols, such as the Open Archives
Initiative Protocol for Metadata Harvesting (OAI-PMH) (Lagoze et al., 2004). When a digital library system is deployed
in an organization, it functions as a knowledge base which stores explicit and externalized knowledge from the
employees. The metadata-rich search feature of the system also allows employees to precisely and promptly locate pieces
of knowledge which can be adapted to timely solve the problem at hand. In this regard, a digital library system thus
promotes the combination and internalization of knowledge in the SECI model.
4. 4. BLOG+DL FRAMEWORK FOR COMPUTER-AIDED ENGINEERING DESIGN
4.1 Technology Application Framework
Based on the SECI model, the features of a KM system that promote the conversion and interaction of tacit and explicit
knowledge among individuals are identified in this section, and the framework for the application of Blog and Digital
Library to build such a KM system is presented in parallel.
Socialization and Externalization
From Figure 1, the first part of the spiral of knowledge creation is interpersonal. It starts when a group of people that share
the same interest gather, build a field of interaction, socialize, and externalize their tacit knowledge to share experiences.
A desirable KM system should help these people to discover each other and provide them a convenient means for
socialization and externalization.
The statistics about blogs in Section 3.1 may prove that Blog can be used as an effective KM tool in this regard. Blog
publication and the social networking features help people to discover each other and create online social networks of
bloggers on which issues of common interests are expressed and personal opinions, as well as experiences, are exchanged.
When Blog is used as an engineering KM tool, an engineer may blog about a design problem that he is trying to solve, e.g.,
how to setup a proper design criterion for a construction project. The blog entry may describe the engineer’s view towards
the problem as well as the available approaches, and may also contain initial research work, such as hyperlinks to other
blog entries about “lesson learned” from similar projects. When published to the Internet or a corporate intranet, the blog
entry is read by a large number of people, many of which may share the same interest or have experienced the same
problem. A reader may assist the engineer in finding a solution by posting his opinion or experience, such as the limitation
of the selected approach, as a comment to the blog entry. Another reader may view the problem differently and does not
agree with the first reader’s opinion. He may prefer to express his opinion on a personal blog and notify the original
blogger in the form of trackback. The original blogger can participate in the discussion thread created by this series of
comments and trackbacks and be able to find a more appropriate design criterion for his project. This blog discussion
thread may also benefit a public audience who may have had the similar problem and comes across this discussion thread
on a Web search engine. In this way, the group of people who share the same interest is gathered; a field of interaction is
made; and these people are equipped with a tool to socialize and exchange experiences, i.e., pieces of tacit knowledge, in
the blog discussion threads.
Combination and Internalization
The second part of the spiral of knowledge creation is intrapersonal. It continues from the interpersonal part when a
person tries to synthesize new explicit knowledge by combining different bodies of explicit knowledge to solve an
unfamiliar problem. After the new knowledge is put into practice, it becomes a valuable know-how that is internalized
into the person’s tacit knowledge base and becomes part of his skills. A desirable KM system should help people to easily
build up repositories of explicit knowledge and allow relevant pieces of knowledge in the repositories to be conveniently
and precisely retrieved so that a more complete set of accessible knowledge can be gathered and combined into the best
possible piece of new knowledge. In terms of internalization, a desirable KM system should also facilitate people in
putting the new knowledge into practice by, for example, in an engineering context, providing them a convenient access to
relevant computational software tools to shorten the time required in a design workflow.
The keywords tagging and selective tag browsing features of Blog, as well as the metadata-rich content archiving and
retrieval features of Digital Library, make Blog and Digital Library complementarily suitable to be effective KM tools in
this regard. Since blog entries created during socialization and externalization are typically tagged with keywords when
they are published, besides conventional keyword and full text searches, the blog owner and the readers can use the
selective tag browsing feature available in most blog servers to filter and browse only through relevant blog entries,
allowing them to stay focused on the important topics being discussed. In addition, an engineer can archive the content
and the metadata of mature blog discussion threads, which contain pieces of externalized tacit knowledge and are the
reflections of the group thinking processes by which solutions to important problems are made, into the collections of the
institutional-repository digital library that he has a membership. He can also archive interesting Web pages, such as
product data sheets, and digital contents, such as Excel, PowerPoint, PDF, Word, and MP3 files, into the collections. In
this way, the engineer builds up a personal portfolio of knowledge that can be shared across the organization, and a digital
library, with its extensive metadata browsing and search features, as well as its full-text indexing capability, becomes a
human-filtered search engine where portfolio owners and peers may use to access the focused set of relevant knowledge
without “noises.” With all the mentioned features, Blog and Digital Library can thereby enhance the efficiency and
effectiveness of the combination and internalization processes of the individuals.

(adapted from Nonaka and Takeuchi 1995)
4.2 System Architecture
A system architecture that corresponds to the proposed application framework is presented in Figure 2. Seven
components, namely, the Web Browser, the Blog Server, the Digital Library Server, the World Wide Web, the Archiver,
the Keyword Suggester, and the Web Service (WS) Portfolio Manager, are involved.
The Web Browser is proposed as the primary user interface for convenient and ubiquitous access to the system and
also because Blog and Digital Library are themselves Web-based. An engineer can use a Web browser to create an
account on a blog server and a digital library, and use it to log on to the blog server to socialize and externalize his
knowledge by publishing blog entries or joining blog discussion threads.
The Archiver is a special-purpose component that monitors the request from a Web browser to take the “snapshot”
of a blog discussion thread or a Web page and archive it to specific collection in a digital library. It is the primary
component that assists in building up the personal portfolios of knowledge. When a blog discussion thread has matured,
the blog owner may summarize the discussion and use a Web browser take a snapshot of the thread. The Web browser
would prompt him to enter the metadata, such as the title, the author’s name, keywords, and a brief description of the
thread, as well as his digital library account name and the title of the collection, i.e., portfolio of knowledge, to which he is
allowed to submit. It would then delegate the task to the archiver by submitting the collected information along with the
URL of the thread and request that a snapshot of the thread be taken and processed accordingly. In addition, an engineer
may use the Web browser and the archiver to take snapshots of interesting Web pages, such as discussion threads, product
datasheets, or design tips, into his portfolio. During the combination and internalization processes, when explicit
knowledge from various sources are crystallized into new explicit knowledge and put into practice, the engineer then use
the Web browser to access relevant discussion threads in blogs and pieces of knowledge collected in personal portfolios in
the digital library, as explained previously. Since Blog and Digital Library are independent technologies that do not
naturally interoperate; the use of common metadata is proposed to enable such interoperation, i.e., the keywords assigned
to blog entries and digital library items should be from the same controlled set and the bibliographic information assigned
to them should conform to the same data format (e.g., DD-MM-YYYY for dates) so that relevant knowledge in blogs and
the digital library can be retrieved simultaneously with a common search query. The Keyword Suggester is proposed as
the component that handles the enforcement of such common metadata.
Besides exchanging and commenting on traditional documents and multimedia contents, an engineer may
participate in the SECI modes of knowledge conversion by exchanging and commenting on computational tools, such as
mathematical routines, numerical analysis modules, and design shortcuts. An engineer can develop these computational
tools as subroutines (or methods, in the object-oriented programming paradigm) in favorite programming languages, such
as Java or VB.NET, and allow them to be remotely executed by other computers as Web services on the Internet. To
“publish” a Web service, i.e., to make a subroutine available for remote access, an engineer first places the code of the
subroutine onto a Web service server, such as Apache Axis for Java or Microsoft Internet Information Server for
VB.NET. The server would automatically generate the “Web service description document” that corresponds to the
subroutine. This document contains the instruction for computers and people on how to programmatically execute the
service. The engineer can next post the Web service description document in a blog entry, along with a brief description of
the service, its theoretical explanation, and a user’s guide. In this way, the service is advertised and made accessible to the
6. public. Discussions about the service, such as usage experiences, can be exchanged as blog comments and trackbacks in
the fashion similar to the ordinary use of blogs in socialization and externalization. The Web services published through
blog entries are discovered when the entries are visited by the fellow bloggers. Besides reading the contents, e.g.,
descriptions and explanations, blog readers can execute the service or build up the portfolios of computational tools, i.e.,
Web services, for later execution with the assistance of the Web service portfolio manager. The Web service portfolio
manager, a component added on to the blog server, detects whether the content of a blog entry includes a hyperlink to the
description document of a Web service. If it does so, an “Execute” button and a “Save” button will be provided in the Web
page that displays the blog entry so that the readers can choose to execute the service or save it to the portfolios in their
accounts for later uses. In the latter case, the user will be asked to provide the description of the desired Web service when
a computational service is needed. The Web service portfolio manager would search the user’s portfolio and retrieve a list
of Web services that best match the request. Once a Web service is selected by the user, the user can execute the Web
service by entering the input data and clicking the Execute button. The selection of Web services from portfolios and the
execution of Web services are performed intelligently according to the Semantic Web Services Framework for
Computational Mechanics (SWSCM) (Vacharasintopchai et al., 2007). The Web service portfolio manager performs the
service consumer and the matchmaker roles in the SWSCM. The readers are referred to the mentioned reference for
in-depth information about the Semantic Web Services technology and its application in engineering design.
Figure 2. Blog+DL Framework for Computer-Aided Engineering Design
5. IMPLEMENTATION
Based on the proposed Blog+DL framework for computer-aided engineering design, a prototype system has been
developed to assist engineers in socializing and externalizing their knowledge, as well as in building up personal
portfolios of knowledge and computational tools. The knowledge and tools in such portfolios can be combined and
crystallized into new knowledge and can also be shared with peers, super- and subordinates of the engineers to form a
larger organizational KM system. The implementation of the prototype system follows the system architecture presented
in Section 4.2 which, excluding the World Wide Web, consists of six components, namely, the Web Browser, the Blog
server, the Digital Library server, the Archiver, the Keyword Suggester, and the Web Service (WS) Portfolio Manager.
The prototype system was implemented in Java and JavaScript and utilized open-source software tools. Mozilla
Firefox (Mozilla, 2007), an extensible standards conformant Web browser which is available on Windows, Linux, and
Mac OS X, was chosen as the Web Browser component. Blojsom (Blojsom, 2007), a blog server developed in Java with
extensive support for third-party add-on modules, was chosen as the Blog server. DSpace (DSpace, 2007a), a widely
accepted large-scale Java digital library server based on the institutional repository concept, with extensive documented
set of APIs, was chosen as the Digital Library server. The Archiver was developed as a Java servlet that monitors the
requests to archive documents at particular URLs along with the provided sets of metadata into specific collections in
7. DSpace. A bookmarklet—a JavaScript code embedded in a Web browser bookmark—was developed as a bridging user
interface between Mozilla Firefox and the archiver. The bookmarklet was deployed as a “Save to DSpace” button in
Mozilla Firefox bookmarks toolbar. Once clicked it prompts the user to enter the brief description and the metadata of a
Web page and forwards the request to the Archiver to proceed. The Keyword Suggester was implemented as a servlet that
provides ontology-assisted keyword suggestion. It consults a predefined set of ontologies to extract relevant keywords
from the Web contents at specific URLs. The bookmarklet uses the Asynchronous JavaScript and XML (AJAX)
programming technique to consult the Keyword Suggester and retrieve a list of suggested keywords for the Web page
being saved. The keywords are prepopulated into the “keywords” textbox to assist users in entering proper metadata.
Ontology-assisted keyword suggestion is helpful to enforce a controlled set of keywords, which is necessary for the
interoperation of Blog and Digital Library and the effective retrieval of content in large digital library collections. The
same functionality is also provided in the blog entry editing module of Blojsom to suggest proper keyword tags when
entries are created or modified. For increased productivity, a federated search function, implemented as a pair of Java
servlet and bookmarklet, was also developed to receive a query from the user, simultaneously search the blog entries in
Blojsom and the digital library items in DSpace, and summarize the results into a single Web page. The Web service
portfolio manager was implemented as an add-on module to Blojsom and utilized the Semantic Web Services
infrastructure developed in Vacharasintopchai et al. (2007).
5. DEMONSTRATION
Figures 3 through 5 demonstrate the typical application of the prototype: Initially, an engineer needs to visit the homepage
of the Blog and the Digital Library servers to create an account on the system. Next, he will be directed to the bookmarklet
installation page where the system verifies his account name (Figure 3a) and generates the “Save to DSpace” and the
federated search bookmarklets (Figure 3b) which can be dragged and dropped to the bookmark toolbar of Mozilla Firefox.
The engineer can now start blogging right away by visiting the “Add Blog Entry” page in his blog account and writing
about his ideas and plan for a project (Figure 4a). The Keyword Suggester is consulted in the background as the engineer
composes his blog entries. He will be presented with the list of suggested keywords in the “Smart Keyword Suggestions”
section where, although not recommended, user-specified keywords can also be entered if desired keywords are not
available (Figure 4b). When the “Add Blog Entry” button is clicked, the entry will be listed in the homepage of the
company (Figure 4c), where recent entries from all staff members are aggregated. The ideas and plan of the engineer will
be read by colleagues and the opinions and experiences are exchanged in the “Comments” section (Figure 4d).
The engineer can also use the “Save to DSpace” bookmarklet to archive discussion threads and potentially useful
Web pages to his account in DSpace (Figures 5a, 5b) to build up his personal portfolio of knowledge (Figure 5c). He can
then use the federated search bookmarklet to simultaneously searched through the discussion threads and the portfolios of
knowledge contributed by him and the colleagues (Figure 5d) and the results will be summarized in a conveniently
accessible Web page (Figure 5e). Web services published through blog entries can also be executed right away from the
results page with the assistance of the Web Service Portfolio Manager (Figure 5f). In this way, the engineer and his fellow
staff members are equipped with an integrated set of tools that can be used to better share explicit knowledge and
experiences.
6. CONCLUSION
This paper has proposed a framework for the application of Weblog, Digital Library, and Semantic Web Services
technologies in engineering knowledge management. The framework is based on the theory of organizational knowledge
management which explains that knowledge is created by the interactions between tacit knowledge and explicit
knowledge among individuals in an organization. In contrast to the KM initiatives in the late 1990s, the focus of this
framework is on facilitating the conversion, interaction, and sharing of tacit and explicit knowledge, which are the bases
in creating knowledge itself, rather than on capturing the individual pieces of explicit knowledge. The proposed
framework also differs from many modern KM tools for engineering design firms in the literature because it is based on
various Internet standards besides HTTP and HTML and therefore promotes cross-system interoperability and advanced
application of Web technologies, such as Web feeds and Web Services, which are the enabling technologies for Web 2.0,
a.k.a. the social Web, and the Internet-based multiplatform distributed computing, respectively. The introduction of
Semantic Web Services technologies into the framework and the application of ontology, which is the fundamental
component of the Semantic Web, in the implementation of the system prototype also open KM systems that conform to
the proposed framework to a wide variety of Internet-based artificial intelligence technologies that would further improve
the knowledge and the productivity of the engineers in today’s ever globalized and competitive world.
