商务元搜索引擎中域语义映射问题研究

Study of Domain Semantic Mapping in E-commerce MetaSearch Engine

电子商务元搜索引擎系统将出售相同产品的多个电子商务引擎界面集成在一起,提供统一的访问接口,给用户的访问和产品的比较提供了极大的方便。当涉及的产品域太多时,需要添加一个域映射模块,将用户的常规查询映射到正确的域上。本文采用本体作为信息的组织形式,不但提高了查询的相关性,而且可以扩充涉及的产品域;并且提供了一个记忆模型,提高频繁查找的效率。

E-commerce metasearch engine system integrates multiple E-commerce search engines selling similar products and provides a unified access ,this makes great convenience for users in searching and comparing products from multiple sites .However, it is necessary to add a module of domain mapping to map the user＇s regular query to the wanted domain when involving too many domains. In this paper , using ontology to organize information can not only improve the relevance of query but also expand the product domains,and providing a memory module to enhance the efficiency of frequent query.
