Effective Automatic Dynamic Semantic Web Service Composition

Web services are a popular technology used when diverse software system integration is in demand. The ability to make some functionality available through the Web has inspiring consequences. One of the intensively researched areas is the study how Web services can be used to dynamically create a functionality, based on the actual requirements. The basic idea is that multiple Web services can be combined together to form a composite service supplying more complex needs. The composition is realized automatically, on the fly, based on the actual goal. To facilitate this kind of Web service utilization, additional metadata depicting the functionality of single services is required. These metadata are provided in a form of semantic annotations. Our work deals with selected subproblems of the automatic dynamic semantic Web service composition. The sub-problems include the proper description of the behavior of Web services, management of the changes in the service environment, and handling multiple composition requests arriving continuously.
