Towards Distributed Ontologies with Description Logics

– Two distinct applications may use two different ontologies to refer to the same concept. Thanks to mapping between these ontologies, association of these concepts can be derived. – One particular application (e.g., a semantic annotation of a document) can use different ontologies to refer to two distinct concepts. These concepts, may be related by mapping, and so further semantic consequences...

Imprecise SPARQL: Towards a Unified Framework for Similarity-Based Semantic Web Tasks

This proposal explores a unified framework to solve Semantic Web tasks that often require similarity measures, such as RDF retrieval, ontology alignment, and semantic service matchmaking. Our aim is to see how far it is possible to integrate user-defined similarity functions (UDSF) into SPARQL to achieve good results for these tasks. We present some research questions, summarize the experimenta...

Pattern-based Ontology Construction

Large and complex enterprise systems face the same kind of information processing problems that exist on the web in general, and constructing an ontology is a crucial part of many solutions. Construction of enterprise ontologies needs to be at least semi-automatic in order to reduce the effort required, and another important issue is to introduce further knowledge reuse in the process. In order...

Improving Email Conversation Efficiency by Enhancing Email with Semantics

Despite persisting in popularity, email is still plagued with information overload, hindering the workflow of data handled by the user. Just as Semantic Web technologies promise to revolutionize the Web, we aspire to use the same technology to enhance electronic mail with useful semantics. Thus we will tackle one of the largest flaws of the email communication genre the lack of shared expectati...
