Consistent description and representation method of user interests are required for personalized Web applications. In this paper, we provide a formal definition and the “e-foaf:interest” vocabulary for describing user interests based on RDF/OWL and the FOAF vocabulary. As an application, under the framework of unifying search and reasoning (ReaSearch), we proposed interests-based unification of...

Design/methodology/approach The article analyzes different methods previously developed for authority control as well as IFLA and ALA standards for managing bibliographic records. Semantic Web technologies are also evaluated. AUTHORIS relies on Drupal and incorporates the protocols of Dublin Core, SIOC, SKOS and FOAF. The tool has also taken into account the obsolescence of MARC and its substit...

The most popular collaborative filtering implementations require either a critical mass of referenced resources and a lot of active users. Other solutions are based on finding a referral with an expertise on the given domain of discourse. In this article we present the semantic social collaborative filtering solution to information retrieval. We describe how the concept of users’ managed collec...

When seeking information through mechanisms such as word of mouth, people choose information sources and make trust judgments about these sources based on a range of factors, including the expertise of the source in relevant fields. In this paper we describe the Hoonoh Ontology, a vocabulary for describing these factors and publishing associated data on the ...

This article investigates several well-known social network applications such as Last.fm, Flickr and identifies social data portability as one of the main technical issues that need to be addressed in the future. We argue that this issue can be addressed by building social networks as Semantic Web applications with FOAF, SIOC, and Linked Data technologies, and prove it by implementing a prototy...

Since more than a decade, theoretical research on ontology evolution has been published in literature and frameworks for managing ontology changes have been developed. However, there are less studies that analyze widely used ontologies developed in a collaborative manner to understand community-driven ontology evolution in practice. In this paper, we perform an empirical analysis on how four we...

This demo will show a practical approach to interoperability between RDF and Topic Maps, based on the RTM vocabulary for mapping RDF data to Topic Maps. The demo will use the freely downloadable (registration required) Omnigator topic map browser. We will take an RDF file containing RDF data in the FOAF vocabulary [6] and show how this can be converted to a topic map, then browse the topic map ...

In this paper we analyse a social structure of an online community defined through tagging practices, and investigate whether useful knowledge about the evolution of social networks can be mined through tagging practices, and whether a more representative social structure has any influence on the tagging experience itself. The results from tagging behaviors also need to be represented semantica...

Over the past several years, a lot of research has been done on the concept of semantic web. However, the research and implementation of the semantic web has predominantly focused on making data machine-understandable while neglecting personal information and human relationships. The social semantic web is a catchall term for defining and presenting social information such as friendship in a ma...

Tourism is the world’s largest and fastest growing industry. There are conventional tourism service providers which are competitively trying to provide the best travel services to customers based on their interests. The Semantic Web is a major endeavour to enhance the Web by enriching its content with semantic (meta)data that can be processed by inference-enabled Web applications. eTourism is a...
