Sever-al principles are introduced such as database miniaturization,the entire structure and the main modules are explained in detail. Compared with a centralized structure,the distributed structure has several ad-vantages including high speed, efficient usage of network bandwidth, less security problems, etc. The system uses feedback of the users to judge the information quality, select search engines and update databases. So,the system performances are improved.展开更多
从电子商务环境下服装供应链管理的需求出发,分析了目前服装搜索引擎存在的问题,提出了基于语义Web服务的分布式服装商品搜索引擎系统模型,并讨论了它的体系结构。介绍了基于Ontology Web Language(OWL)的服装本体设计模型及其语义描述...从电子商务环境下服装供应链管理的需求出发,分析了目前服装搜索引擎存在的问题,提出了基于语义Web服务的分布式服装商品搜索引擎系统模型,并讨论了它的体系结构。介绍了基于Ontology Web Language(OWL)的服装本体设计模型及其语义描述方法。分析了服装搜索引擎的基本功能及分布式环境下的Web Services(WS)合成。理论分析和实例原型说明了基于服装语义树的搜索引擎多关键词搜索效率明显高于全文搜索引擎。展开更多
