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...

This paper proposes X-KIF – a new modeling language intended for implementing large, formal knowledge bases. The language originated from the SUO-KIF language, which has been used for implementing a large family of ontologies based on the Suggested Upper Merged Ontology (SUMO).We address some...

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...

LDAP based directory services constitute important parts of the IT infrastructure of many organizations and enterprises. They act as a central service for integrating new applications into an IT infrastructure and can be accessed by many different types of clients ranging from content management...

Wikis as well as collaborative tagging have been subject of very intense research last years and active discussion topics in the so-called blogsphere as well. In this paper, we propose collaborative Wiki tagging based on the idea to exploit inherent semantics of the concept of link in Wiki. The...

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...

Knowledge necessary for the creation of business process models is distributed, consists of different types, and expresses different levels of abstraction. Its acquisition and collection into a common knowledge base, which implies integration into a single model, is the goal of the approach we...

Up until now, crucial life science information resources, whether bibliographic or factual databases, are isolated from each other. Moreover, semantic metadata intended to structure their contents is supplied in a manual form only. In the StemNet project we aim at developing a framework for...

We developed a prototype to support data integration and decision making in Breast Cancer domain, wherein the knowledge management plays a critical role. While the decision making needs to rely on different medical expertise, our system experiments with a system ontology and then a process...

The desideratum of semantic interoperability has been intensively discussed in medical informatics circles in recent years. Originally it was assumed by many that this issue could be addressed simply by insisting on the application of shared clinical terminologies. More recently however the use...
