Service Identification, Description, Comparison and Search in the Service Space In the context of the Semantic Web, the term "services" has been often used as synonym for Web services. However Web services build only a small fraction of all available services. This talk will introduce the service space, its dimensions and classify known service types in the space. For different service types and use cases formalisms with different expressivities are required in order to describe service offers and service requests. While obtaining semantic service descriptions is alone quite challenging, scalability of search algorithms becomes an important issue especially when expressive formalisms are used. In the talk, a novel semi-automatic technique for the acquisition of semantic descriptions will be presented. The talk will discuss challenges in the area of service search and introduce offline indexing technique as a way to gain efficiency of service search.
