One my main research topic is the Context-Aware Data Tailoring, the goal of this research is to exploit contextual information, properly captured by a model we are developing, to filter information coming from heterogeneous data sources. The result will be common semantic view over the relevant portion of the available data. The system we are developing is named Context-ADDICT (Context-Aware Data Design Integration Customization and Tailoring), more details can be found here.
A presentation of Context-ADDICT is available here.
