报告摘要:

 As more and more RDF data become available on the web, the question of how end users can access this body of knowledge becomes of crucial importance. Although  SPARQL is a standard way to access RDF data, it remains tedious and difficult  for end users because of the  complexity of the SPARQL syntax and the RDF schema. An ideal system should allow end users to profit from the expressive  power of Semantic Web standards (such as RDF and SPARQLs) while at the same time hiding their complexity behind an intuitive and easy-to use interface. Therefore, RDF question/ answering (Q/A) systems have received wide attention in both NLP (natural language  processing) and DB (database) areas. In this talk, besides reviewing some existing work about RDF Q/A in both NLP and DB areas, we introduce our recent work along this direction. Specifically, we design a graph- based RDF Q/A system, called gAnswer, representing an natural language question as a query graph.  Then, we answer natural language questions by employing subgraph matching process.We also present another work, automatically building templates for RDF Q/A, which is based on joining natural language query workloads and SPARQL query workloads.
