SHARE: A Web Service Based Framework for Distributed Querying and Reasoning on the Semantic Web

摘要

Here we describe the SHARE system, a web service based framework fordistributed querying and reasoning on the semantic web. The main innovations ofSHARE are: (1) the extension of a SPARQL query engine to perform on-demand dataretrieval from web services, and (2) the extension of an OWL reasoner to testproperty restrictions by means of web service invocations. In addition toenabling queries across distributed datasets, the system allows for a targetdataset that is significantly larger than is possible under current,centralized approaches. Although the architecture is equally applicable to alltypes of data, the SHARE system targets bioinformatics, due to the large numberof interoperable web services that are already available in this area. SHARE isbuilt entirely on semantic web standards, and is the successor of the BioMOBYproject.
