Planning Based Integration of Web Services

Abstract

In this paper a planning system for goal directed integration of Web services is presented. The presented model extends classical planning to manage some forms of non determinism in service execution and to manage collections of objects. The dynamical evolving domain of available Web services require flexible tools for composing the given resources in order to fulfil user goals which are also unpredictable. Automated planning techniques can be efficiently used to realise dynamical and adaptive Web service composition. The domain of available services is represented by a set of planning operators, the behaviour of the composed service is described by a final goal and the generated solution plans are used for synthesis of Web service scripts
