Abstract

Service oriented architecture is becoming a more and more important approach for connecting heterogeneous computer systems in wide area networks. One of the mayor problems is the discovery of suitable web service which we would like to include in business process, because the descriptions of web services are not formally defined. Meanwhile the syntactic properties are well defined, the semantics present in description of web service are at a very low level. Because of the tendency to create very high level of automatization and independence of the users, the research area of semantic web services has advanced very rapidly. Large numbers of proposals for semantically annotated web services, algorithms and tools have arisen in the recent years. The following work will illustrate different ontologies with which we can achieve that the description of web service is not understandable only to the human users but also to computers. We will examine a selection of algorithms, which are distinguished by complexity and ways of comparing elements of semantic web services. I will analyse the tools which use the above mentioned algorithms and therefore enable the semantic web service discovery. In the end I will present examples of web service discovery described in three different ontologies.
