semantically enhanced service discovery engine. This solution extends service
descriptions using RDF and changes UDDI APIs for support of semantic search.
Moreover, Pokraev, Koolwaaij, and Wibbels (2003) present the design and implementation
of an enhanced UDDI server, capable of storage, matching, and retrieval
of semantically rich service profiles that contain contextual information, mapping
DAML-S to UDDI publish message and introducing, with their approach, additional
elements such as a matchmaker, an ontology repository, and a proxy API to invoke
UDDI APIs. The approach of Pokraev et al. (2003) does not change the publish
and inquiry interfaces of the UDDI. In addition, Paolucci, Kawamura, Payne, and
Sycara (2002) show how DAML-S service profiles, which describe service capabilities
within DAML-S, can be mapped into UDDI records and how the encoded
information can be mapped within the UDDI registry to perform semantic matching.
This work proposes semantic search based on an externally created and operated
matchmaker, as the semantic data are stored outside of the UDDI registry, while
the mapping is implemented with links from the UDDI tModel to the semantic
profile of the Web service.
