摘要
基于本体语义研究地理信息服务发现问题。将加权语义距离和Wu-Palmer法相结合并进行改进计算本体概念语义相似度。引入服务接口依赖关系,提出支持接口多态性的本体语义地理信息服务输入输出匹配方法。最后开发实验原型对基于本体的地理信息服务匹配方法进行实验与分析。
It presents the geographic information service discovery method based on ontology semantic.Weighted semantic distance and Wu-Palmer method are combined to improve the calculating method of ontology concept semantic similarity.Service interface dependent relations are introduced to promote the geographic information service input/output matching method which supports interface multi-condition.Finally,experimental prototype is developed to practice and analyze the geographic information service discovery method based on ontology semantic.
