Much of the recent work in Semantic Search is concerned with addressing the challenge of finding entities in the growing Web of Data. However, alongside this growth, there is a significant increase in the availability of ontologies that can be used to describe these entities. Whereas several methods have been proposed in Semantic Search to rank entities based on a keyword query, little work has been published on search and ranking of resources in ontologies. To the best of our knowledge, this work is the first to propose a benchmark suite for ontology search. The benchmark suite, named CBRBench, includes a collection of ontologies that was retrieved by crawling a seed set of ontology URIs derived from prefix.cc and a set of queries derived from a real query log from the Linked Open Vocabularies search engine. Further, it includes the results for the ideal ranking of the concepts in the ontology collection for the identified set of query terms which was established based on the opinions of ten ontology engineering experts.]]>

The continuous growth of the Linked Data Web brings us closer to the original vision of the Web as an interconnected network of machine-readable resources. There is, however, an essential aspect in principle still missing from this vision, i.e., the ability for the Web user to interact directly with the Linked Data in a read/write manner. In this presentation we introduce a lifecycle and associated mechanism to enable a domain-agnostic read/write interaction with Linked Data in the context of a single data provider. Our solution uses an ontology to build a binding front-end for a given RDF model, in addition to RDFa to maintain the semantics of the resulting form/widget components. On the processing side, a RESTful Web service is provided to seamlessly manage semantic widgets and their associated data, and hence enable the read/write data interaction mechanism. The evaluation shows that the generation process presents no performance issues, while the content overhead required for the actual form-data binding is kept to a minimum.]]>

HTTP and HTML and the Web itself enter their third decade of existence. Still, the Web continues to transform human communication, information sharing, commerce, education, and entertainment. Social networking, cloud computing, and the convergence of Web, television, video and online gaming are among the phenomena stretching the Web in exciting new directions. In this talk, Armin will present what the World Wide Web Consortium (W3C), overlooking and steering the development of new Web standards is up to for the third decade of the Web. The W3C community is building an Open Web Platform that will enable the Web to grow and foster future innovation. This presentation present technology highlights of 2011 for advancing the Web platform. Focus topics of this talk will be the new HTML5 standard, the Data for Web Applications initiative which includes the next generation of RDF, and standards that allow people to create Semantic Web enabled Web Apps that have access to data from a variety of sources, including data-in-documents (RDFa) and data-from-databases (W3C's RDB2RDF).]]>
