This document provides a lecture on data integration and fusion using RDF. It presents an example of integrating data from three governmental databases (Ministry of Justice, Chamber of Commerce, Ministry of Economy) about companies by transforming each database into RDF and concatenating the RDF graphs. Entities are then linked across datasets using URIs. A practical session is described where student groups will map university student records from three different data schemes into RDF and integrate the data, writing SPARQL queries over the integrated dataset.

A SEMANTIC BASED APPROACH FOR INFORMATION RETRIEVAL FROM HTML DOCUMENTS USING...cscpconf
Most of the internet applications are built using web technologies like HTML. Web pages are designed in such a way that it displays the data records from the underlying databases or just displays the text in an unstructured format but using some fixed template. Summarizing these data which are dispersed in different web pages is hectic and tedious and consumes most of the time and manual effort. A supervised learning technique called Wrapper Induction technique
can be used across the web pages to learn data extraction rules. By applying these learnt rules to web pages, enables the information extraction an easier process. This paper focuses on
developing a tool for information extraction from the unstructured data. The use of semantic web technologies much simplifies the process. This tool enables us to query the data being scattered over multiple web pages, in distinguished ways. This can be accomplished by the following steps – extracting the data from multiple web pages, storing them in the form of RDF triples, integrating multiple RDF files using ontology, generating SPARQL query based on user query and generating report in the form of tables or charts from the results of SPARQL query. The relationship between various related web pages are identified using ontology and used to query in better ways thus enhancing the searching efficacy.

RDF Schema provides the framework to describe application-specific classes and properties.
RDF Schema ‘semantically extends’ RDF to enable us to talk about classes of resources, and the properties that will be used with them.
Classes in RDF Schema is much like classes in object oriented programming languages. This allows resources to be defined as instances of classes, and subclasses of classes.
RDF schemas are Web resources (and have URIs) and can be described using RDF

Discovering Resume Information using linked data dannyijwest
In spite of having different web applications to create and collect resumes, these web applications suffer
mainly from a common standard data model, data sharing, and data reusing. Though, different web
applications provide same quality of resume information, but internally there are many differences in terms
of data structure and storage which makes computer difficult to process and analyse the information from
different sources. The concept of Linked Data has enabled the web to share data among different data
sources and to discover any kind of information while resolving the issues like heterogeneity,
interoperability, and data reusing between different data sources and allowing machine process-able data
on the web.

Design and implementation of the web (extract, transform, load) process in da...IAESIJAI
Owing to the recent increased size and complexity of data in addition to management issues, data storage requires extensive attention so that it can be employed in realistic applications. Hence, the requirement for designing and implementing a data ware-house system has become an urgent necessity. Data extraction, transformation and loading (ETL) is a vital part of the data warehouse architecture. This study designs a data warehouse application that contains a web ETL process that divides the work between the input device and server. This system is proposed to solve the lack of work partitioning between the input device and server. The designed system can be used in many branches and disciplines because of its high performance in adding data, analyzing data by using a web server and building queries. Analysis of the results proves that the designed system is fast in cleaning and transferring data between the remote parts of the system connected to the internet. ETL without missing any data consumes 0.00582 seconds.
An introduction to linked data (semantic web) for a Knowledge and Information Network (KIN) webinar. The presentation shows some examples of linked data in action, data visualization, difference between open and linked data and how linkd data is being used in UK gov and local gov.
Talk delivered at YOW! Developer Conferences in Melbourne, Brisbane and Sydney Australia on 1-9 December 2016.
Abstract: Governments collect a lot of data. Data on air quality, toxic chemicals, laws and regulations, public health, and the census are intended to be widely distributed. Some data is not for public consumption. This talk focuses on open government data — the information that is meant to be made available for benefit of policy makers, researchers, scientists, industry, community organisers, journalists and members of civil society.
We’ll cover the evolution of Linked Data, which is now being used by Google, Apple, IBM Watson, federal governments worldwide, non-profits including CSIRO and OpenPHACTS, and thousands of others worldwide.
Next we’ll delve into the evolution of the U.S. Environmental Protection Agency’s Open Data service that we implemented using Linked Data and an Open Source Data Platform. Highlights include how we connected to hundreds of billions of open data facts in the world’s largest, open chemical molecules database PubChem and DBpedia.
WHO SHOULD ATTEND
Data scientists, software engineers, data analysts, DBAs, technical leaders and anyone interested in utilising linked data and open government data.
A SEMANTIC BASED APPROACH FOR KNOWLEDGE DISCOVERY AND ACQUISITION FROM MULTIP...cscpconf
The data from internet are dispersed in multiple documents or web pag-es. Most of them are not properly structured and organized. It becomes necessary to organize these contents in order to improve the search results by increasing the relevancy. The semantic web technologies and ontologies play a vital role in in-formation extraction and new knowledge discovery from the web documents. This paper suggests a model for storing the web content in an organized and structured manner in RDF format. The information extraction techniques and the ontologies developed for the domain together discovers new knowledge. The paper also proves that the
time taken for inferring the new knowledge is also minimal compared to manual effort when semantic web technologies are used while developing the applications.

By understanding these aspects, students can gain a comprehensive view of synthetic fiber production, its impact on society and the environment, and the potential for future innovations. Synthetic fibers play a crucial role in modern society, impacting various aspects of daily life, industry, and the environment. ynthetic fibers are integral to modern life, offering a range of benefits from cost-effectiveness and versatility to innovative applications and performance characteristics. While they pose environmental challenges, ongoing research and development aim to create more sustainable and eco-friendly alternatives. Understanding the importance of synthetic fibers helps in appreciating their role in the economy, industry, and daily life, while also emphasizing the need for sustainable practices and innovation.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

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
