This article describes an ontology framework called bio-zen, which can be used for the representation of information from biomedical research on the Semantic Web. The ontology framework adheres to the OWL DL format and is based on existing foundational ontologies and metadata standards like...

Although we live in the age of multimedia, most information is still only available in text format. This is especially true in medical informatics. Consequently, research in text mining is an essential area of computer science. With the aid of statistic and linguistic procedures, text mining...

Accurate mapping and merging of multiple ontologies to produce consistent and coherent merged global ontology is a very important process to enable heterogeneous multivendors semantic-based systems to communicate and understand each other. Current systems for ontology mapping and merging are...

ConTag is an approach to generate semantic tag recommendations for documents based on Semantic Web ontologies and Web 2.0 services. We designed and implemented a process to normalize documents to RDF format, extract document topics using Web 2.0 services and finally match extracted topics to a...

The EU project APOSDLE focuses on work-integrated learning. Among the several challenges of the project, a crucial role is played by the system’s ability to start from the context of the immediate work of a user, establish her missing competencies and learning needs and suggest on-the-fly and...

There is currently no model that is capable of representing the actual content of web resources together with their semantic web meta-data. This paper presents requirements for semantic content management, a unified human-browsable and human-editable semantic web content model (SWCM), and its...

A key factor for success of companies operating in a globalized market environment is a modern SOA-based infrastructure. An essential component of a SOA infrastructure is the central service registry. Current standards for organizing service registries and their implementations are driven by the...

The evolution of the semantic web brings new possibilities to handle the information overload. This paper presents a solution on how to navigate the web in a semantically meaningful way and to create reports of items of interest on demand. The proposed solution is based on semantic navigation,...

This paper examines issues on Philosophy of Artificial Intelligence (AI), Cognitive Science and Mental Models. The paper provides a philosophical grounding for the researchers in Personal Information Management (PIM). An overview is given on various philosophical aspects of computer-based...

This paper describes the VAMP web application for the validation of MPEG-7 descriptions with respect to semantic constraints defined in a profile. The semantic constraints are formalised using an ontology and a set of rules. -- Metadata ; ontology ; semantic web ; MPEG-7 ; validation
