Execution Order

This chapter addresses concepts and methods to support dynamic composition of situated services. We focus mainly on service modelling and service design for execution environments that can support dynamic composition of situated services. In our approach, services are modelled using UML 2.x collaborations that are mapped to parts of a UML 2.x design model. Services are also associated with situations, that is, sets of properties that characterise the executing environment of the service. A policy-driven mechanism is proposed to enhance the service composition process. The policy model takes into account context situations and user preferences that can impact the performance and functionalities of the composed services. Within a given situation, executable services are identified and service composition policies used to determine their execution order. We demonstrate the approach using a multi-media over IP service that takes into account security requirements, monitored threat levels, user locations and preferences.

Composition Process

Web Service (WS) composition consists in combining several WSs into a Composite WS (CWS), which becomes a value-added process. In order to provide reliable and fault-tolerant CWSs, several transactional-aware composition approaches have been proposed. However, as far as we know, no real classification survey of such approaches exists. This is the contribution of this chapter. Our classification distinguishes the more relevant and recent propositions in two groups: approaches based on WS transactional properties and the ones also integrating QoS criteria to the composition process. All these studied approaches are compared according to several criteria: the transactional model used or proposed, the control flow model used or automatically generated, the mechanism proposed to verify the transactional property of the composition, the step(s) of the composition process involved in, and the protocols or the standard languages used or extended. This classification allows underlining the lacks and the future directions which should be studied.

Šio mokslinio tyrimo tematika nagrinėja internetinių paslaugų kompozicijos atlikimo priemones ir būdus. Straipsnyje aprašomi vartotojo poreikiams pritaikytų internetinių paslaugų kompozicijos automatiniai ir pusiau automatiniai kūrimo būdai ir metodai, plačiau nagrinėjamos šių metodų galimybės ir apribojimai. Analizuojami moksliniuose straipsniuose pateikiami internetinių paslaugų kompozicijos atlikimo metodai ir išskiriami trys pagrindiniai šių paslaugų kompozicijos būdai: darbų srautų modeliais grindžiamas, paslaugų šablonais grindžiamas ir automatinis paslaugų kompozicijos metodas. Tyrimo tikslas – pateikti pasiūlymą, kuris leistų automatiniu ar pusiau automatiniu būdu kurti internetinių paslaugų kompozicijas pagal vartotojų poreikius. Pusiau automatinio internetinių paslaugų komponavimo uždavinio sprendimo būdą iliustruoja sudėtingas kelionės planavimo pavyzdys. Internetinių paslaugų kompozicijai atlikti siūloma taikyti dirbtinio intelekto planavimo metodus. Pateikiama tokio uždavinio sprendimo koncepcija, kuri grindžiama fragmentiniais kituose projektuose gautais paslaugų komponavimo rezultatais ir bando sujungti visą internetinių paslaugų kompozicijos procesą: nuo vartotojo keliamų kompozicijos reikalavimų įvedimo iki tinkamo paslaugų kompozicijos rezultatų pateikimo. Possibilities of automatic and semi-automatic end-user driven web service compositionDalė Dzemydienė, Arūnas Miliauskas  SummaryOur research work relates to the main principles, means and current limitations of the end-user driven automatic and semi-automatic web service composition. It analyses automatic and semi-automatic composition approaches found in literature and classifi es them as workfl ow-based, template-based and automatic methods. The aim of this research is to provide a proposal how to construct semiautomatic or automatic end-user driven web service composition. An approach is illustrated by the multi-complexity of service composition in travel domain. We analyze a conceptual solution that covers the whole composition process: from an end-user submitting composition requirements until the presentation of the a composition execution results. Some methods of an artifi cial intelligence (AI) planning research fi eld were used in proposed web service composition approach.
