As an RDF representation of information extracted from Wikipedia, DBpedia has been serving as an interlinking hub for many other RDF data sets in the Linked Open Data cloud on the Web of Data. Therefore, accessing the DBpedia data set is a common task for various Semantic Web applications. Given the fact that DBpedia is currently accessed through public SPARQL endpoints, which requires the users to...
The W3C's Media Fragments URI 1.0 specification provides for a media-format independent, standard means of addressing media fragments on the Web using Uniform Resource Identifiers (URIs). Thus, a key requirement is for the User Agent (UA) to efficiently retrieve media fragments identified by URIs from the regular media server over the HTTP protocol. This paper addresses the issue of how to construct...
Despite the wealth of information contained in the Web of Linked Data, the current limitations and entry barriers of the Semantic Web technologies hinder the users from taking advantage of these information resources. Linked Data visualization can alleviate this problem. In this paper, we adopt a proper Linked Data visualization model, design Linked Data visualization algorithms, and develop a lightweight,...
Deep Web databases contain huge amounts of data that can only be accessed via the front-end Web form queries. Since query clients cannot directly issue SPARQL queries against the Deep Web databases, Semantic Web applications cannot take advantage of this information resource. Recently, many RDB2RDF mapping tools, relying on mapping languages such as W3C's R2RML, provide the ability to view existing...
