复杂上下文感知的组合服务选择框架

摘要

In ubiquitous network environment,not only the Web Service context but also user's context is taken into account in composition selection. And the data type describing context attribute may be real number,interval number,triangular fuzzy number and intuitionistic fuzzy number. To address the difficulty of based on complex context composition service selection this paper presents a complex context-aware composition service selection framework. It can aware service context and user context. The framework is based on the design of intelligent agents, in which the client frameworks complete the user's context management, server frameworks complete service context management and composition service selection. By comparing with the related works, the advantages and effectiveness of our approach is demonstrated.%泛在网络环境中,组合服务选择不仅需要考虑服务上下文还需要考虑用户上下文,而描述上下文属性的数据类型可能有实数、区间数、三角模糊数和直觉模糊集.为解决这种基于复杂上下文的组合服务选择难题,本文提出一个复杂上下文感知的组合服务选择框架,能够感知服务上下文和用户上下文.该框架基于智能主体设计,其中用户端框架完成用户上下文管理,服务端框架完成服务上下文管理和组合服务选择.通过相关工作的比较,验证了该框架的优越性和有效性.
