When applied semantic integration technology to databases, common method is to rewrite semantic query into SQL statements, while only RDFs vocabularies are supported at most. Semantics having been realized is weak. A more perfect algorithm inherited from the idea of rewriting semantic query is proposed, a sub set of OWL is supported, and semantics having been supported is more deep than ever. Ontology...
Web service infrastructures access heterogeneous remote systems to execute Web service requests. The way in which these remote systems are accessed is not standardized and requires to perform complex integration tasks which are often solved by developing adapters. In this paper, we apply a virtualization approach so that Web service infrastructures can rely on existing adapters instead of writing...
We present a data quality manager (DQM) prototype providing information regarding the elements of derived non-atomic data values. Users are able to make effective decisions by trusting data according to the description of the conflict resolution function that was utilized for fusing data along with the quality properties of data ancestor. The assessment and ranking of non-atomic data is possible by...
