Unified Semantic Search of Data and Services

The increasing availability of data and eServices on the Weballows users to search for relevant information and to perform operations through eServices. Current technologies do not support users in the execution of such activities as a unique task; thus users have first to find interesting information, and then, as a separate activity, to find and use eServices. In this paper we present a framework able to query an integrated view of heterogeneous data and to search for eServices related to retrieved data. A unique view of data and semantically describedeServices is the way in which it is possible to unify data andservice perspectives.
