semantic cluster

For existing Web service discovery mechanism inefficiencies and the precision rate is not high, we proposed an ontology-based semantic Web services cluster and discovery framework. Firstly, we proposed the ontology-based Semantic Web service description model.

针对现有的Web服务发现机制中存在的效率低下和查准率不高的两个问题，提出了一种基于本体的语义Web服务聚类和发现框架。首先，提出了基于本体的语义Web服务描述模型。

The documents in semantic cluster are semantically related with query by the query-guided activation, decreasing the risk caused by topic distraction of feedback documents.

以用户查询为导向的激活方式在语义上将聚类下的文档与查询关联起来，克服了反馈文档主题分散同现带来的风险。
