Title: Querying Semantic Web Data with SPARQL (and SPARQL 1.1)


摘 要Abstract:

The Semantic Web is the initiative of the W3C to make information on the Web readable not only by humans but also by machines. RDF is the data model for Semantic Web data, and SPARQL is the standard query language for this data model.

In the last ten years, we have witnessed a constant growth in the amount of RDF data available on the Web, which have motivated the theoretical study of some fundamental aspects of SPARQL and the development of efficient mechanisms for implementing this query language.  In this talk, we survey some of the main results about the theory of RDF and SPARQL, putting emphasis on some of the new features of the language (such as navigation and federation) that were recently introduced in SPARQL.
