“…Such approach-used by Agarwal et al [8], Akkiraju et al [9], Klusch and Gerber [29], McIlraith and Son [23], Rodríguez-Mier et al [30], Sohrabi et al [31], Traverso and Pistore [24], Wu et al [25], among others-has a few practical obstacles in order to be put into production scenarios. There is the need for complete formal descriptions of each service, sometimes requiring a detailed description of service interactions, as in [23,24], for example.…”

“…Using logic-enabled semantic languages provided by the Semantic Web (SW) [4] community, automated composition tools are able to find service compositions that meet the developer requirements, but only if the underlying services are correctly described in terms of their capabilities. Such approaches go beyond the typical Web service description by looking at enriched input and output descriptions [5][6][7], and pre-and postconditions [8,9].…”

Background: Service Composition is an important feature of Service Oriented Computing, yet it remains mostly a manual process. Given the dynamic and decentralized nature of services, manual composition is a complex undertaking. Proposals to automate this process exist, but suffer from practical problems that hinder their implementation. Methods: In this paper, we introduce a pragmatic approach where we reverse engineer a service composition repository to obtain the necessary information for automated solutions to work. We then evaluate the quality of the automated compositions based on their similarity to the ones written manually. A classic planning algorithm was adapted in order to generate solutions closer to those expected by developers. Results: The use of classical planning tools is too time-consuming for agile development scenarios. A simplified, tailored implementation can be orders of magnitude faster than a generic planner, which suggests that expressive power may need to be sacrificed in favor of usability. Our evaluation showed that ensuring the adherence of the solution to the initial specification by enforcing the use of all input parameters was capable of significantly increasing the quality of the solutions. Conclusions: It is possible to increase the quality of automated composition by applying planning algorithms specially crafted for the service composition task. Comparisons with automated planning tools highlight the effectiveness of our proposal.

This paper presents HAUTO, a framework able to compose convergent services automatically. HAUTO is based in HTN (hierarchical task networks) Automated Planning and is composed of three modules: a request processing module that transforms natural language and context information into a planning instance, the automated composition module based on HTN planning and the execution environment for convergent (Web and telecom) services. The integration of a planning component provides two basic functionalities: the possibility of customizing the composition of services using the user context information and a middleware level that integrates the execution of services in high performance telecom environments. Finally, a prototype in environmental early warning management is presented as a test case.Keywords: telecommunications, services composition, automated planning. RESUMENEste artículo presenta HAUTO, un framework que permite componer automáticamente servicios convergentes. HAUTO se basa en la planificación automática basada en redes jerárquicas de tareas HTN y se compone de tres módulos: un módulo de procesamiento de la solicitud, que transforma el lenguaje natural e información del contexto en una instancia de planificación, el módulo de composición automática basado en la planificación HTN; y el tercero, es el entorno de ejecución para servicios convergentes (Web y Telecom). La integración de un componente de planificación provee dos funcionalidades básicas: la posibilidad de personalizar la composición de los servicios usando la información del contexto del usuario y un middleware que se integra con la ejecución de los servicios en entornos de Telecomunicaciones de alto rendimiento. Finalmente, se presenta como caso de estudio un prototipo para la gestión de alertas ambientales tempranas.Palabras clave: telecomunicaciones, composición de servicios, planificación automática.

Abstract. In this paper a holistic approach to automated service composition in Service Oriented Architecture is presented. The model described allows to specify both functional and non-functional requirements for the complex service. In order to do so a decomposition of the complex service composition process into three stages is proposed, in which a structure, a scenario and an execution plan of a complex service is built. It is believed that service composition tool based on the proposed model will be able to create complex services satisfying efficiently both functional and nonfunctional requirements.
