SWI-Prolog and the Web

Where Prolog is commonly seen as a component in a Web application that is either embedded or communicates using a proprietary protocol, we propose an architecture where Prolog communicates to other components in a Web application using the standard HTTP protocol. By avoiding embedding in external Web servers development and deployment become much easier. To support this architecture, in addition to the transfer protocol, we must also support parsing, representing and generating the key Web document types such as HTML, XML and RDF. This paper motivates the design decisions in the libraries and extensions to Prolog for handling Web documents and protocols. The design has been guided by the requirement to handle large documents efficiently. The described libraries support a wide range of Web applications ranging from HTML and XML documents to Semantic Web RDF processing.

Preservation through access: the AHDS performing arts collections in ECLAP and Europeana

This poster provides an overview of the ongoing rescue of valuable digital collections that had been taken down and consequently lost to general access. The University of Glasgow was home to the Arts and Humanities Data Service Performing Arts (AHDS Performing Arts) [1], one of the five arts and humanities data centres that constitute the Arts and Humanities Data Service (AHDS). Since 1996 AHDS supported the creation, curation, preservation and reuse of digital materials for the UK Arts and Humanities research and teaching community. AHDS Performing Arts, based in Glasgow, supported research, learning and teaching in music, dance, theatre, radio, film, television, and performance for thirteen years. Working with the AHDS Executive, relevant performing arts collections have been ingested, documented, preserved, and where possible made available via the AHDS Cross Search Catalogue and Website to researchers, practitioners, and the general public. Furthermore strong relationships were developed with research and teaching community upon a scoping study investigating user needs [2]. In 2007 the co-funders of the AHDS - Arts and Humanities Research Council (AHRC) for the UK and the Joint Information Systems Committee (JISC) - withdrew their funding. A detailed risk assessment report was produced in response to the withdrawal of core funding [3], but to no avail. When the AHDS funding stopped, online access to these cultural resources eventually became discontinued [4]. In 2010, the School of Culture and Creative Arts at the University of Glasgow joined the EU-funded ECLAP project to ensure that at least part of these resources could be accessible for the long term by scholars and practitioners in the performing arts arena, and by the general public. Below we briefly describe the ECLAP project, the AHDS Performing Arts collections progressively available through it and some thoughts on providing preservation through access for this type of digital cultural resources

Extension of ImageNotion to Allow Privacy-Aware Image Sharing

A growing number of users in Web 2.0 based social network sites and photo sharing portals upload millions of images per day. In many cases, this leads to serious privacy threats. The images reveal not only the personal relationships and attitudes of the user who uploads the images, but those of other persons displayed in the images as well. In this paper, we propose a system architecture for privacy-aware image sharing. Our approach is based on the ImageNotion application, which combines automated processes to create high-quality semantic image annotations

Europeana Creative. EDM Endpoint. Custom Views

The paper discusses the Europeana Creative project which aims to facilitate re-use of cultural heritage metadata and content by the creative industries. The paper focuses on the contribution of Ontotext to the project activities. The Europeana Data Model (EDM) is further discussed as a new proposal for structuring the data that Europeana will ingest, manage and publish. The advantages of using EDM instead of the current ESE metadata set are highlighted. Finally, Ontotext’s EDM Endpoint is presented, based on OWLIM semantic repository and SPARQL query language. A user-friendly RDF view is presented in order to illustrate the possibilities of Forest - an extensible modular user interface framework for creating linked data and semantic web applications

Interlinking educational data to web of data

With the proliferation of educational data on the Web, publishing and interlinking eLearning resources have become an important issue nowadays. Educational resources are exposed under heterogeneous Intellectual Property Rights (IPRs) in different times and formats. Some resources are implicitly related to each other or to the interest, cultural and technical environment of learners. Linking educational resources to useful knowledge on the Web improves resource seeking. This becomes crucial for moving from current isolated eLearning repositories towards an open discovery space, including distributed resources irrespective of their geographic and system boundaries. Linking resources is also useful for enriching educational content, as it provides a richer context and other related information to both educators and learners. On the other hand, the emergence of the so-called "Linked Data" brings new opportunities for interconnecting different kinds of resources on the Web of Data. Using the Linked Data approach, data providers can publish structured data and establish typed links between them from various sources. To this aim, many tools, approaches and frameworks have been built to first expose the data as Linked Data formats and to second discover the similarities between entities in the datasets. The research carried out for this PhD thesis assesses the possibilities of applying the Linked Open Data paradigm to the enrichment of educational resources. Generally speaking, we discuss the interlinking educational objects and eLearning resources on the Web of Data focusing on existing schemas and tools. The main goals of this thesis are thus to cover the following aspects: -- Exposing the educational (meta)data schemas and particularly IEEE LOM as Linked Data -- Evaluating currently available interlinking tools in the Linked Data context -- Analyzing datasets in the Linked Open Data cloud, to discover appropriate datasets for interlinking -- Discussing the benefits of interlinking educational (meta)data in practice

Training resources and e-Government services for rural SMEs : the rural inclusion platform

Rural Inclusion, a project supported by the Information and Communication Technologies Policy Support Programme of the European Commission, aims to adopt, adapt, and deploy a Web infrastructure, in rural settings, combining semantics with a collaborative training and networking approach, offering e-Government services that will be supported by a rigorous and reusable service process analysis and modeling, and facilitating the disambiguation of the small businesses needs and requirements when trying to carry out the particular transactions. This paper, presents an overview of the architecture of RuralObservatory2.0 which will play the critical role of training content and eGovernment services repository of the overall Rural Inclusion platform.</jats:p

A Survey on Linked Data and the Social Web as facilitators for TEL recommender systems

Personalisation, adaptation and recommendation are central features of TEL environments. In this context, information retrieval techniques are applied as part of TEL recommender systems to filter and recommend learning resources or peer learners according to user preferences and requirements. However, the suitability and scope of possible recommendations is fundamentally dependent on the quality and quantity of available data, for instance, metadata about TEL resources as well as users. On the other hand, throughout the last years, the Linked Data (LD) movement has succeeded to provide a vast body of well-interlinked and publicly accessible Web data. This in particular includes Linked Data of explicit or implicit educational nature. The potential of LD to facilitate TEL recommender systems research and practice is discussed in this paper. In particular, an overview of most relevant LD sources and techniques is provided, together with a discussion of their potential for the TEL domain in general and TEL recommender systems in particular. Results from highly related European projects are presented and discussed together with an analysis of prevailing challenges and preliminary solutions.LinkedU
