- W2113174380 abstract "We present an approach to identifying the minimal set of potentially relevant Semantic Web data sources for a given query. Our solution involves the adaptation of an efficient information integration algorithm that has polynomial time complexity. We then use these selected sources and an OWL reasoner to answer queries on the Semantic Web. We introduce a concept of source relevance expressed in OWL to reduce the number of sources needed to get the answers to a query. As the Semantic Web is an autonomous entity, some of the data sources may contain data that are not described directly in terms of a given query ontology. In our solution we define and use a mapping language that is a subset of OWL for the purpose of aligning heterogeneous ontologies. Our implemented system supports a subset of SPARQL queries, simple OWL ontologies and data sources that commit to them. Since the time to load sources is a dominating factor in performance, and our system identifies the minimal set of potentially relevant sources, it is very efficient. We have conducted an experiment using synthetic ontologies and data sources which demonstrates that our system performs well over a wide range of queries. A typical response time for a given work load of 20 domain ontologies, 20 map ontologies and 400 data sources is approximately 1 second. Furthermore, our system returned correct answers to 200 randomly generated queries in three different data configurations." @default.
