Ontology mapping is a prerequisite for achieving heterogeneous data integration on the Semantic Web. The vision of the Semantic Web implies that a large number of ontologies present on the web need to be aligned before one can make use of them, for example, a question answering on the Semantic Web. At the same time, these ontologies can be used as domain-specific background knowledge by the ontology...
This paper presents a method to enhance location awareness by using semantic composition of AT-LOCATION and PART-WHOLE semantic relations. The method generates axioms that infer new location relations based on relations that are extracted by a semantic parser. Experimental study with WordNet glosses shows that the method increases the amount of location knowledge by two orders of magnitude. The precision...
Nowadays, we are assisting to a paradigmatic shift for the development of web applications due to the pervasive distribution of their components among a lot of servers, which are dynamically interconnected by web links. As a consequence, the application logic is often defined by exploiting workflow languages since they are more suitable to address the complexity of these new running environments....
Ontology engineering has been fully or partially practiced by knowledge engineers or knowledge workers, towards delivering either fully fledged conceptualizations of domains or providing lightweight ontology versions for less demanding but more frequent knowledge tasks. Domain-specific information can be shaped into ontologies either manually or (semi-)automatically using ontology learning techniques...
