一种基于知识复用的动态服务组合方法

Approach to Dynamic Services Composition Based on Knowledge Reuse

如何在业务层面即时动态组合服务,按需创建应用,是一个具有挑战性的课题。提出了一种适合业务用户使用的基于知识复用的服务组合方法,该方法充分利用领域专家的知识和经验,将其封装成组合模板透明地提供给用户,使用户可以在业务层面以一种大粒度的方式描述需求,建立业务应用,从而提高了业务用户主动参与面向服务的应用构造的能力和构造效率。

How to make full use of Web services and construct application by composing existing services on demand in the dynamic and open environment is a challenge issue.This paper presented an approach to larger-granularity service composition for business-users,which encapsulated domain knowledge into prefabricated and modifiable templates.By this approach,business-users can construct applications just like assembling hardware by composing reusable and larger-granularity modules,which facilitates automated service composition and enhances abstract level to some extent.
