服务描述本体是基于语义的服务聚合的基础.目前本体构建主要由领域专家手工进行,具有成本高、时间长、不易演化等困难,不能满足mashup生态系统对本体的需要.标签作为一种在各类服务注册体系中被广泛使用的大众分类手段,从功能、认知的角度对服务进行描述,是群体智能的一种体现.提出了一种从标签自动构建m ashup服务描述本体的方法,该方法利用大众分类,可以自下而上地进行自动化本体构建,并能随网络化的服务资源变化而自行演化.最后,通过实例验证了该方法的有效性.
Service description ontology is the foundation of semantic-based service aggregation.At present, ontology construction is mainly carried out manually by field experts, which is difficult to meet the needs of mashup ecosystem ontology because of its high cost, long time, It is an embodiment of group intelligence to describe the service from the perspective of function and cognition.A method of automatically constructing mashup service description ontology from tags is proposed, The method makes use of mass classification to build the ontology from the bottom up and to evolve with the change of the networked service resources.Finally, the effectiveness of the method is verified by an example.
