Usage of AI-planning techniques to solve problems of Web-services composition

O.V. Zakharova

Abstract


Automated composition of services described by their process model is difficult but very vital task. Its decision needs strict formalization and strong semantization of a service. Similarity of definitions of intelligent planning tasks and services composition objectives demonstrates the possibility of using AI-planning approaches for resolving Web services composition problems, provided a number of solutions to existing problems. In this article the analysis of task similarity and differences of HTN-planning and composition of Web-services presented by process model is executed. BPEL-services are considered. It is defined main problems that appears when AI-planning methods are used and it is proposed approaches for their resolving by integration DL and HTN-planning. Translation algorithms from BPEL to HTN-DL is also discussed.
