In this study, combining the semantic similarity with the product taxology, a product Semantic Relevance Model is set up, the structure of this model is acquired by the training of an Industry Semantic Training Center, finally semantic information that extracted from products is integrated with current Item-Based Collaborative Filtering approach.

本文针对现有电子商务推荐系统中存在的数据稀疏性问题和系统冷开始问题，结合语义相似性以及产品分类学的方法，提出建立产品的语义关联模型，该模型的结构通过一个行业语义信息训练中心的训练得到，最终产品的语义信息被提取出来集成到现有的基于项目的协同过滤方法中。

Underlain by these studies, several representative BI products from well-known IT software providers are investigated, and the status quo of BI"s application inside and outside China is summerized. Then based on the author"s practical experience in a large stated-owned enterprise, the implementation of BI in this enterprise is researched and its internal mechanism is analyzed and evaluated, moreover, some coding experiments of an explorative system that aims at the implementation of relation rules mining functions are conducted. Finally, the problems from the BIs application in China are discussed and some corresponding strategies are proposed.

在此基础上，本文多角度多层次地重点研究了商务智能的应用：分析了主流软件供应商的商务智能产品，总结了国内外应用现状；深入国内某大型企业，在实践基础上剖析了该企业的商务智能实施状况、商务智能系统机理并对其加以评价；进行了小型试验系统的探索性研究，完成了数据挖掘中关联规则的代码实现；从国家和行业、企业、软件、管理咨询、项目实施等五个宏观与微观角度，探讨了国内商务智能应用中存在的问题，并探索性地提出了相应的解决方案。
