随着网络上服务资源的快速增长,如何准确地发现服务、提高已发现服务的可信度成为一个亟待解决的关键问题.有研究表明,Web上以目标驱动的查询方式可以返回更准确的结果.因此,在已获取的领域服务目标基础上,提出一种基于Wiki和WordNet中词汇间关系的服务目标知识扩充方法,并且通过ProgrammableWeb网站提供的真实服务集验证了该方法的可行性和有效性.实验结果表明,该方法可以有效地对服务目标知识进行扩充.基于扩充的服务目标知识,一定程度上可提高服务发现、推荐方法的可信度,并且能够为具有相同角色的用户的需求描述提供指导.
With the rapid growth of service resources on the Internet, how to accurately discover services and improve the credibility of discovered services has become a key issue to be solved urgently.Researches have shown that the goal-driven query on the Web can return more accurate results Therefore, based on the acquired domain service goals, a method of service target knowledge extension based on the relationship between wikis and WordNet is proposed, and the feasibility and effectiveness of the method are verified through the real service set provided by ProgrammableWeb website The experimental results show that this method can effectively extend the service target knowledge.Based on the expanded service target knowledge, it can improve the credibility of service discovery and recommendation methods to some extent, and can describe the requirements of users with the same role Provide guidance.
