TripleProv - Linked Data Provenance
TripleProv is an in-memory RDF database capable to store, trace, and query provenance information in processing Linked Data queries. TripleProv returns an understandable description, at multiple levels of granularity, of the way, the results of a SPARQL query were derived.
TripleProv gives a detailed explanation of which pieces of data and how were combined to produce the answer of a query. Moreover, with TripleProv you can tailor query execution with provenance information. You can input a provenance specification of the data you want to use to derive the answer. For example, if you are interested in articles about “Obama”, but you want the answer to come only from sources attributed to “US News”.
