This research area focuses on the study and development of techniques to facilitate the access to data for a specific search of information on the Web or other types of data sources (for example, relational databases). Through the use of semantic technologies, such as ontologies, reasoners based on description Logics, etc. The aim is to determine the semantic meaning of the available data to provide users with the necessary information that fulfils their needs.
Here are some of the applications of systems based on semantic technologies, created in current and past SID research projects. Prototype applications demonstrate the possibilities of semantic technologies applied to distributed and heterogeneos data access, showing real benefits for end users. These applications have been built on the foundation of semantic software tools, semantic services and the Semantic Web infrastructure (led by W3C).
