Abstract


Even though the Linked Data movement is gaining ground, vast amounts of information are only present in the traditional Web of human-readable pages. Data from such sources in the Surface Web and the Deep Web needs to be published as structured data into the Linked Data Web. The work described in this paper links the schema and individuals in the RDF extracted from surface and deep Web sources with the schema and individuals already present in the linked data cloud. To this end, we extend our prior work on automatically generating Semantic Web Services from Web sources. Once we are able to link individuals of the generated Semantic Web Service with the data present in the linked data cloud, we can populate the Linked Data Web with data from Deep Web sources for given domains. Our approach not only integrates known sources from the Deep Web into the Linked Data Web, but also automatically discovers and links previously unknown sources for the same domain. Our techniques can significantly increase the amount of data available in the Linked Data Web.
