[Objective] The article aims at building W2R framework for converting Web data to RDF format. [Methods] Build the bottom infrastructure of the framework with W2R vocabulary, and convert Web data to RDF format with mapping file which is consisted of system Ontology and Web page elements extracted in XPath syntax. Furthermore, use Virtuoso database as the persistent storage of RDF data. [Results] With the W2R framework, it is convenient for converting Web data to RDF format, merging data in different resources, storing them in named graphs and implementing simple inferences without changing any source code. [Limitations] The system Ontology is made up of public namespaces that describe the bibliographies currently. RDF data is only stored in Virtuoso database. [Conclusions] Through the W2R framework, this paper provides a new way of generating the standardized RDF data for semantic network and linked data applications.
