本体驱动的地理信息服务发现模型研究

An Ontology-driven Discovering Model of Geographical Information Services

  • 摘要: 引入地理信息服务本体的概念,提出了本体驱动的地理信息服务发现模型,研究了地理信息服务的多级匹配算法,通过量化地理信息服务的功能相似度和信誉相似度,根据待选服务和服务请求之间的相似度阈值,对服务进行匹配和筛选。设计了本体驱动的地理信息服务注册中心,从查全率、查准率、响应时间、副本负载等指标对本体驱动的地理信息服务发现进行了测试。结果证明,该模型具有查全率和查准率高、动态负载平衡等特点。

     

    Abstract: We propose an ontology-driven discovering model of geographical information services to improve the recall and the precision of geographical information services,study the multilevel matching arithmetic of geographical information services.This arithmetic filters and matches the services in service register center according as the similarity between services selected with services requested through defining the function similarity and credit standing similarity.The matching arithmetic,geographical information services ontology,and semantic describing form the discovering model.The results show that the ontology-driven discovering model is excellent in recall and precision,and can maintain dynamic loading balance of service copy.
