The paper deals with the abstract planning problem - the first stage of Web Service Composition (WSC) in the Planics framework. We present a solution based on a compact repre-sentation of abstract plans by multisets of service types and a reduction of the planning problem to a task for an SMT-solver. The paper presents theoretical aspects of the abstract planning as well as some details of our symbolic...
The paper presents a new approach based on nature inspired algorithms to an automated abstract planning problem, which is a part of the web service composition problem. An abstract plan is defined as an equivalence class of sequences of service types that satisfy a user query. Intuitively, two sequences are equivalent if they are composed of the same service types, but not necessarily occurring in...
The paper proposes a method of converting the problem of automated composition of web services to the problem of building a graph of worlds consisting of formally defined objects. We present basic rules of defining ontologies for services execution environments, in which automatic reasoning about sequences of service calls leading to saatisfying a user's intention is possible. The intention can be...
