针对垂直搜索引擎存在检索效率低、检索结果不准确等问题，将自动分类引入到垂直搜索引擎中以提高信息查询的效率和准确性。在阐述垂直搜索引擎概念和特点的基础上，从垂直搜索引擎的专业、精确、深入三个特点出发，分析了自动分类在垂直搜索引擎中的作用，构建了集成自动分类的垂直搜索引擎系统框架，并对该框架中自动分类计算、集成自动分类的信息检索、集成自动分类的信息浏览和关联推荐等关键技术进行了探讨。最后，通过一个实例阐释了自动分类集成到垂直搜索引擎中的技术实现与应用效果。

英文摘要：

Tosolve problems such as the low efficiency and the poor accuracy of information search in the vertical search engine （VSE） , the automatic classification technique is introduced into VSE to improve the efficiency and the accuracy of information search. After the concept and features of VSE are described, the benefits of automatic classification technique integrated into VSE are analyzed from VSE＇s characteristics： specialization, accuracy and deepness. Based on these, an architecture of the VSE integrated with automatic classification technique is built, and key technologies in the architecture are discussed and studied, which are automatic classification algorithm, auto- matic classification-integrated information search, browsing and recommendation. Finally, an example is introduced to demonstrate the implementation and the effects of automatic classification integrated VSE
