Abstract

New systems can be created by assembling a set of elementary services provided by various stakeholders in a service composition. Service composition is not a trivial endeavor and several composition methods exist. Yet, these methods are hardly adopted by the field, as they need a set of well-defined and well- described services and are not able to deal with incomplete information and unambiguous descriptions. Furthermore, these methods are not able to deal with situations in which stakeholders have different requirements and need to negotiate with each other about the selection and performance of services.In this paper we present a service composition method and evaluate this method using a quasi-experimental design. The method is aimed at dealing with a set of heterogeneous services provided by stakeholders with different and sometimes even opposing requirements. We found that our composition method helps to create an overview of services and their attributes and enables better communication between stakeholders. A recommendation for further research is to integrate semantic and multi-actor composition methods.

公共网络中的服务组合:准实验结果

可以通过在服务组合中组装由不同涉众提供的一组基本服务来创建新系统。服务组合不是一项微不足道的工作，存在几种组合方法。然而，这些方法很难被该领域所采用，因为它们需要一组定义良好且描述良好的服务，并且无法处理不完整的信息和明确的描述。此外，这些方法不能处理利益相关者有不同需求，需要就服务的选择和性能相互协商的情况。本文提出了一种服务组合方法，并用准实验设计对该方法进行了评价。该方法旨在处理一组由具有不同甚至相反需求的涉众提供的异构服务。我们发现，我们的组合方法有助于创建服务及其属性的概览，并支持涉众之间更好的通信。建议进一步研究整合语义和多角色组合方法。
