摘要
采用基于知识的框架表示法和产品信息特征的层次描述方法,设计企业中不同类型产品信息的描述元数据模型和检索元数据模型,实现了产品生产者按照基于关键词集合的方式来描述企业产品信息和客户按照基于关键词集合的方式来描述要检索的企业产品信息。在此基础上,构建企业产品信息库的逻辑结构和企业产品信息访问组织平台,实现了基于多关键词集合的企业产品信息描述和检索的统一。实验表明 。
Enterprise product information(EPI) metadata models of description and retrieval are designed,which are based on representation method of knowledge frame and cascade description method of product information character, so that describe the EPI with a form based on

muster(KM) and retrieve EPI with a form based on KM. Then, in order to unify EPI information of the description and retrieval, the logical structures of EPI database and the EPI access organization platform are constructed that are based on the different EPI description metadata models and EPI retrieval metadata models.The experiment shows that the speed and veracity are improved by far than the ordinary net retrieval.Key words:EPI
