Workshop on Semantic Search over the Web (SSW 2011)

SSW 2011As part of the 23rd International Conference on Advanced Information Systems Engineering, CAiSE 2011, two staff at DCU’s School of Computing, Paolo Cappellari and Mark Roantree, together with a colleague at University Roma Tre, Roberto De Virgilio, organised the first workshop on Semantic Search over the Web (SSW 2011). The SSW workshop was to provide a forum for discussion and advancement of data management in searching web, and in relationships with semantic web technologies that propose new models, languages and applications.

We are witnessing a smooth evolution of the Web from a worldwide information space of linked documents to a global knowledge base, composed of semantically interconnected resources. To date, the correlated and semantically annotated data available on the web amounts to 25 billion RDF triples, interlinked by roughly 395 million RDF links. The continuous publishing and the integration of semantic datasets from companies, government and public sector projects is leading to the creation of the so-called Web of Knowledge.

Each semantic dataset contributes to extend the global knowledge and increases its reasoning capabilities. Researchers are now looking with growing interest to semantic issues in this huge amount of correlated data available on the Web. Many progresses have been made in the field of semantic technologies, from formal models to repositories and reasoning engines. While many practitioners focus on exploiting semantic information to contribute to IR problems from a document centric point of view, we believe that such a vast, and constantly growing, amount of semantic data raises data management issues that must be faced in a dynamic, highly distributed and heterogeneous environment such as the Web.
