Abstract:
The need for filtering of services results from the ever growing number of available Web services that may be used to compose various business applications. Some of the available Web services offer similar functionalities, thus the need to differentiate between them occurs. The Semantic Web services filtering process is therefore based not only on the ontological description of functional aspects of services (i.e. what a service does), but also on a description of nonfunctional ones (i.e. how it performs its functionality). Within the filtering process, both functional and nonfunctional aspects of a service expressed using ontology are confronted with the preferences a user specified and the description of a composite application the service may become a part of. One of the weaknesses of the described filtering process is lack of high efficiency and its complexity as processing ontological descriptions and reasoning on them is time-consuming. In order to speed-up the filtering process, clustering techniques narrowing down the set of potential services to be considered by the filtering mechanism may be applied. In this article the architecture for Semantic Web services filtering and clustering system is briefly discussed.
