The Approach to Web Services Composition

The paper presents an approach to the composition of web services based on their meta descriptions. The process of web services sequence formation is depicted. Such web services sequence describes execution of certain user’s task. The method of user’s tasks scenario formation is proposed that allows to define dynamically an ordered sequence of web services required to run a specific user’s tasks. The scenario formation for real user’s task “Calculation of the strength for the power components of magnetic systems” is represented, approving the applicability and efficiency of proposed approach.
