Semantic Web Services (SWS) propose to extend the traditional Web Services technologies on the
way to consolidate ontologies and semantics. This makes it possible to select, integrate and
invocate services dynamically. In this way, services are able to dynamically adapt themselves to
changes without human intervention. The main purpose of this paper is to present an algorithm for
matching SWS. The algorithm uses the description of the service capabilities to match the semantic
values. The traditional matching has been improved using ontologies which constitute a step further
in the matching algorithms. To implement the algorithm, an agent FIPA compliant architecture has
been designed and developed. The results obtained are positive. The semantic web services
framework developed in combination with the use of the matchmaking algorithm, which allows
finding services based on their similarities.
