Our approach is based on a transformation procedure of OWL ontologies into an Object-Oriented schema and the application of inference production rules over the generated objects in order to implement the various semantics of OWL. In order to enhance the performance of the system, we introduce a dynamic approach of generating production rules for ABOX reasoning and an incremental approach of loading ontologies. O-DEVICE is built over the CLIPS production rule system, using the object-oriented language COOL to model and handle ontology concepts and RDF resources. One of the contributions of our work is that we enable a well-known and efficient production rule system to handle OWL ontologies. We argue that although native OWL rule reasoners may process ontology information faster, they lack some of the key features that rule systems offer, such as the efficient manipulation of the information through complex rule programs. We present a comparison of our system with other OWL reasoners, showing that O-DEVICE can constitute a practical rule environment for ontology manipulation.Mon Jul 07 13:47:29 CEST 2008Internet Computing390-93Embracing Web 3.0112007ieee ai paper semantic rdf v0805 web processing ontology knowledge With the Resource Description Framework (RDF) and Web Ontology Language (OWL) - the languages that power the semantic Web - becoming standards and new technologies reaching maturity for embedding semantics in existing Web pages and querying RDF knowledge stores, something exciting is clearly happening in this area.

This wealth of data has spawned countless mashups that integrate heterogenous information, but using techniques that will not scale beyond a handful of sources. In contrast, the Semantic Web provides the key to large-scale data integration, yet still lacks approachable interfaces allowing contributions from non-specialists. In this paper we present Revyu, a reviewing and rating site in the Web 2.0 mould that is built on Semantic Web infrastructure and both publishes and consumes linked RDF data. This combination of approaches affords ease of interaction for regular users and ease of integration with external data sources.Mon Jul 07 13:47:29 CEST 2008LondonNASA Monographs in Systems and Software EngineeringSemantic Web: Concepts, Technologies and Applications2007web book semantic spatial v0805 rdf knowledge rules service springer ontology ai processing The Web is growing at an astounding pace surpassing the 8 billion page mark. However, most pages are still designed for human consumption and cannot be processed by machines. This book provides a well-paced introduction to the Semantic Web. It covers a wide range of topics, from new trends (ontologies, rules) to existing technologies (Web Services and software agents) to more formal aspects (logic and inference). It includes: real-world (and complete) examples of the application of Semantic Web concepts; how the technology presented and discussed throughout the book can be extended to other application areas.Mon Jul 07 13:47:29 CEST 2008Web Semantics121-28Using the Semantic Web for Linking and Reusing Data across Web 2.0 Communities62008software processing semantic ontology community data knowledge management v0805 ai rdf web paper Large volumes of content (bookmarks, reviews, videos, etc.) are currently being created on the Social Web, i.e. on Web 2.0 community sites, and this content is being annotated and commented upon. The ability to view an individual's entire contribution to the Social Web would be an interesting and valuable service, particularly important as social networks are often being formed through created content and things that people have in common (object-centred sociality). SIOC is a Semantic Web research project that aims to describe online communities on the Social Web. This paper describes how SIOC and the Semantic Web can enable linking and reuse scenarios of data from Web 2.0 community sites, and introduces a SIOC Types module to further specify the type of content items and act as a ´glue¡ between user posts and the content items created and annotated by users.Mon Jul 07 13:47:29 CEST 2008Web Semantics161-69Bridging the semantic Web and Web 2.0 with {Representational State Transfer (REST)}62008web retrieval rdf paper knowledge ai software semantic community service v0805 rest Semantic Web technologies must integrate with Web 2.0 services for both to leverage each others strengths. We argue that the REST-based design methodologies of the web present the ideal mechanism through which to align the publication of semantic data with the existing web architecture. We present the design and implementation of two solutions that combine REST-based design and RDF data access: one solution for integrating existing web services and one server-side solution for creating RDF REST services. Both of these solutions enable SPARQL to be a unifying data access layer for aligning the Semantic Web and Web 2.0.Mon Jul 07 13:47:29 CEST 2008Web Semantics154-60{hGRDDL}: Bridging microformats and RDFa62008web semantic v0805 html rdf ai paper We propose hGRDDL (pronounced h-griddle), a simple mechanism for transforming ad hoc HTML-embedded structured data, such as microformats, into RDFa. This technique preserves the advantages of the original syntax, notably the correspondence between the rendered HTML and the related structured data, and requires little change on the publisher end. RDFa tool developers can leverage the existing deployments of microformats, while focusing new deployments on RDFa for greater extensibility and consistency, all using the same client-side toolset. We provide a prototype implementation of the hGRDDL processor and of transformations for hCard and hCal, two popular microformats.Mon Jul 07 13:47:29 CEST 2008Menlo Park, CA, USAFLAIRS 2002 ConferenceFLAIRS2002413-418A Comparison of (Semantic) Markup Languages2002knowledge v0805 ai paper aaai ontology xml web rdf semantic processing Several languages have been proposed as candidates for semantic markup. We needed to adopt a language for our current research on developing user-oriented tools operating over the Semantic Web. This paper presents the results of our analysis of three candidates that we considered: XML, RDF, and DAML+OIL along with their associated schemas and ontology specifications. The analysis focuses on the expressiveness of each language, and is presented along several dimensions and summarized in a comparison table. A surprising result of our analysis is the decision to adopt XML(Schema) for practical reasons, since it is able to accommodate a relatively expressive set of constructs and is widely known and commercially supported. We also discuss how we plan to complement XML(S) with a small set of conventions, so that we will have an easier transition to other markup languages in the future.
