The document summarizes lessons learned from analyzing over 100 Semantic Web applications from challenge competitions over the past decade. It finds that while standards like RDF, OWL and SPARQL are widely used, there remain gaps in publishing and updating Linked Data. Most applications require human intervention for data integration due to noisy RDF data. There is also a mismatch between graph-based data models and relational/object-oriented components. The document recommends addressing these issues through more guidelines, libraries, and software frameworks to improve the software engineering process for building Semantic Web applications.
Enabling Case-Based Reasoning on the Web of Data (How to create a Web of Exp...Benjamin Heitmann
Presentation at the "Reasoning from experiences on the Web" workshop (WebCBR 2010) at the International Conference on Case Based Reasoning 2010.
Abstract:
While Case-based reasoning (CBR) has successfully been deployed on the Web, its data models are typically inconsistent with existing information infrastructure and standards. In this paper, we examine how
CBR can operate on the emerging Web of Data, with mutual benefits. The
expense of knowledge engineering and curating a case base can be reduced
by using Linked Data from the Web of Data. While Linked Data provides experiential data from many different domains, it also contains inconsistencies, missing data and noise which provide challenges for logic-based reasoning. CBR is well suited to provide alternative and robust reasoning approaches. We introduce (i) a lightweight CBR vocabulary which is
suited for the open ecosystem of the emerging Web of Data, and provide
(ii) a detailed example of a case base using data from multiple sources. We
propose that for the first time the Web of Data provides data and a real
context for open CBR systems.

An architecture for privacy-enabled user profile portability on the Web of DataBenjamin Heitmann
Presentation at the Heterogeneous Recommendation Workshop at the ACM Recommender Systems Conference 2010.
Providing relevant recommendations requires access to user profile data. Current social networking ecosystems allow third party services to request user authorisation for accessing profile data, thus enabling cross-domain recommendation. However these ecosystems create user lock-in and social networking data silos, as the profile data is neither portable nor interoperable. We argue that innovations in reconciling heterogeneous data sources must be also be matched by innovations in architecture design and recommender methodology. We present and qualitatively evaluate an architecture for privacy-enabled user profile portability, which is based on technologies from the emerging Web of Data (FOAF, WebIDs and the Web Access Control vocabulary). The proposed architecture enables the creation of a universal “private by default” ecosystem with interoperability of user profile data. The privacy of the user is protected by allowing multiple data providers to host their part of the user profile. This provides an incentive for more users to make profile data from different domains available for recommendations.

Leveraging Matching Dependencies for Guided User Feedback in Linked Data Appl...Umair ul Hassan
https://www.insight-centre.org/content/leveraging-matching-dependencies-guided-user-feedback-linked-data-applications
Presented at IIWeb2012
ABSTRACT
This paper presents a new approach for managing integration quality and user feedback, for entity consolidation, within applications consuming Linked Open Data. The quality of a dataspace containing multiple linked datasets is defined in term of a utility measure, based on domain specific matching dependencies. Furthermore, the user is involved in the consolidation process through soliciting feedback about identity resolution links, where each candidate link is ranked according to its benefit to the dataspace; calculated by approximating the improvement in the utility of dataspace utility. The approach
evaluated on real world and synthetic datasets demonstrates the effectiveness of utility measure; through dataspace integration quality improvement that requires less overall user feedback iterations.

"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.

Approximate Semantic Matching of Heterogeneous EventsSouleiman Hasan
Event-based systems have loose coupling within space, time and
synchronization, providing a scalable infrastructure for
information exchange and distributed workflows. However,
event-based systems are tightly coupled, via event subscriptions
and patterns, to the semantics of the underlying event schema and
values. The high degree of semantic heterogeneity of events in
large and open deployments such as smart cities and the sensor
web makes it difficult to develop and maintain event-based
systems. In order to address semantic coupling within event-based
systems, we propose vocabulary free subscriptions together with
the use of approximate semantic matching of events. This paper
examines the requirement of event semantic decoupling and
discusses approximate semantic event matching and the
consequences it implies for event processing systems. We
introduce a semantic event matcher and evaluate the suitability of
an approximate hybrid matcher based on both thesauri-based and
distributional semantics-based similarity and relatedness
measures. The matcher is evaluated over a structured
representation of Wikipedia and Freebase events. Initial
evaluations show that the approach matches events with a
maximal combined precision-recall F1 score of 75.89% on
average in all experiments with a subscription set of 7
subscriptions. The evaluation shows how a hybrid approach to
semantic event matching outperforms a single similarity measure
approach.

Building Optimisation using Scenario Modeling and Linked DataEdward Curry
As buildings become more complex, it becomes more difficult to manage and operate them effectively. The holistic management and maintenance of facilities is a multi-domain problem encompassing financial accounting, building maintenance, human resources, asset management and code compliance, affecting different stakeholders in different ways. One technique, called scenario modelling, customises data-driven decision support for building managers during building operation. However, current implementations of scenario modeling have been limited to data from Building Management Systems with little interaction with other relevant data sources due to interoperability issues. Linked data helps to overcome interoperability challenges to enable data from multiple domains to be merged into holistic scenario models for different stakeholders of the building. The approach is demonstrated using an owner-occupied office building.

System of Systems Information Interoperability using a Linked DataspaceEdward Curry
System of Systems pose significant technical challenges in terms of information interoperability that require overcoming conceptual barriers (both syntax and semantic) and technological barriers. This paper presents an approach to System of Systems information interoperability based on the Dataspace data management abstraction and the Linked Data approach to sharing information on the web. The paper describes the fundamentals of the approach and demonstrates the concept with a System of Systems for enterprise energy management.

Modern learning models require linking experiences in training environments with experiences in the real-world. However, data about real-world experiences is notoriously hard to collect. Social spaces bring new opportunities to tackle this challenge, supplying digital traces where people talk about their real-world experiences. These traces can become valuable resource, especially in ill-defined domains that embed multiple interpretations. The paper presents a unique approach to aggregate content from social spaces into a semantic-enriched data browser to facilitate informal learning in ill-defined domains. This work pioneers a new way to exploit digital traces about real-world experiences as authentic examples in informal learning contexts. An exploratory study is used to determine both strengths and areas needing attention. The results suggest that semantics can be successfully used in social spaces for informal learning – especially when combined with carefully designed nudges.

Towards Expertise Modelling for Routing Data Cleaning Tasks within a Communit...Umair ul Hassan
https://www.insight-centre.org/content/towards-expertise-modelling-routing-data-cleaning-tasks-within-community-knowledge-workers
Presented at the ICIQ 2012
ABSTRACT:
Applications consuming data have to deal with variety of data quality issues such as missing values, duplication, incorrect values, etc. Although automatic approaches can be utilized for data cleaning the results can remain uncertain. Therefore updates suggested by automatic data cleaning algorithms require further human verification. This paper presents an approach for generating tasks for uncertain updates and routing these tasks to appropriate workers based on their expertise. Specifically the paper tackles the problem of modelling the expertise of knowledge workers for the purpose of routing tasks within collaborative data quality management. The proposed expertise model represents the profile of a worker against a set of concepts describing the data. A simple routing algorithm is employed for leveraging the expertise profiles for matching data cleaning tasks with workers. The proposed approach is evaluated on a real world dataset using human workers. The results demonstrate the effectiveness of using concepts for modelling expertise, in terms of likelihood of receiving responses to tasks routed to workers.
Edinburgh Data-Intensive Research Data-intensive refers to huge volumes of data, complex patterns of data integration and analysis, and intricate interactions between data and users. Current methods and tools are failing to address data-intensive challenges effectively. They fail for several reasons, all of which are aspects of scalability. The deluge of computational methods and plethora of computational systems prevents effective and efficient use of resources, user interfaces are not adopted at a sufficient rate to satisfy demand for scientific computing and data and knowledge is created outside suitable contexts for collaborative research to be effective. The Edinburgh Data-Intensive Research group addresses these scalability issues by providing mappings from abstract formulations to concrete and optimised executions of research challenges, by developing intuitive interfaces to enable access to steer these executions and by developing systems to aid in creating new research challenges. In this talk I will present several exemplars where we have dealt with scalability issues in scientific scenarios.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

10. LD gaps:
publishing/consuming
Digital Enterprise Research Institute www.deri.ie
all applications consume RDF
73% import API, 69% export API
but: incompatible
implementations
LD principles in 2006 led to
consolidation
embedding RDF:
web for humans vs. web for machines
2008: introduction of RDFa

11. LD gaps: beyond open data
Digital Enterprise Research Institute www.deri.ie
writing/changing/updating RDF data
is difficult
71% of apps do not support data
changes
Writing to remote RDF store:
draft status in 2011: SPARQL Update
Restricting access (read/write):
no standards
no interoperability
closest ideas (?): R/W design note, WebID

shortcomings (1)
Digital Enterprise Research Institute www.deri.ie
Integrating noisy RDF data:
60% semi-automatic integration
this involves human intervention
only 20% use automatic heuristics
major part of Semantic Web specific code
Distribution of application logic:
multiple components and standards
queries(41%), rules(52%) or formal
vocabularies
hard to maintain

More guidelines, best
practices and design
patterns:
current examples:
– Linked Data principles and
publishing guidelines
– guidelines for naming of URIs
– Linked Data patterns collection
result: more interoperability,
more coherent Web of Data

More software libraries
(beyond RDF storage!)
guidelines can be hardcoded in
reusable libraries
good libraries can make
complicated guidelines easy to
use (See HTTP, SSL, SMTP and
DNS lookups)
current examples:
– any23, d2r server, Semantic
Web Client Library

More software factories:
create complete applications
requires patterns + libraries
or: “opinionated software”
components can be
customised for domain
Interface, homogenisation
and data discovery usually
made from scratch

18. Appendix: threats to validity
Digital Enterprise Research Institute www.deri.ie
Representativeness:
only complete applications part of challenges (not tools or
libraries)
apps needed to use real-world data
submission of paper describing the app was required
challenge extends of multiple years, allows trends to be seen
Number of authors who verified checklist (65%):
academic email addresses expire quickly
we manually tried to find new email addresses
no source code was used:
source code was not required for challenges due to e.g. IP
issues
