Towards a Graph-Based Approach for Web Services Composition
This work addresses the challenge of integrating distributed applications for developers and organizations, but it appears incremental as it builds on existing graph-based methods without claiming major breakthroughs.
The paper tackles the problem of automatic web services composition by proposing a graph-based approach to represent and order web services, aiming to combine multiple services to solve problems that cannot be addressed individually.
Nowadays, Web services (WS) remain a main actor in the implementation of distributed applications. They represent a new promising paradigm for the development, deployment and integration of Internet applications. The aim of Web services composition is to use the skills of several departments to resolve any problem that cannot be solved individually. The result of this composition is a compound of Web services that define how they will be used. In this paper, we propose an approach for automatic web services composition based on the concepts of directed graphs for the representation and description of Web services, and the ordering of web services compound execution. In this context, the user query, defined by a set of inputs and outputs, can be viewed as a directed graph composed of Web services.
