S5T Scaleable semantic personalised search of spoken and written contents on the Semantic Web

Project summary

Funded from 2006 to 2008 by the Spanish Ministry of Science and Education (TIN2005-06885).

The continuous growth of contents in text and other media on the Web and intranets demands a parallel progress of information access technologies. In this project we propose a) the development of a novel semantic search model, with ontology-based content ranking algorithms, improving and complementing the achievements in this direction in the Semantic Web field, and achieving measurable improvements in search effectiveness with respect to current keyword-based techniques; b) the combination of personalisation techniques with the semantic-based representation models, to achieve improvements in the relative precision and relevance of search results with respect to the particular interests of individual users; c) the integration of text and voice contents in a single access platform for large-scale repositories; and d) an experience in the realisation the of Semantic Web proposals, to contribute to its advancement, including the definition of ontologies, the semi-automatic construction of knowledge bases, and a semi-automatic content annotation system, incorporating speech recognition and human language technologies. A demonstrative application will be built in the news domain, for the evaluation and refinement of the developed techniques, in a real-world application setting.
