摘要

摘要: 为了解决用户在搜索引擎结果列表中寻找所需信息困难的问题,帮助用户快速有效地定位有价值的Web文档,与向量空间模型方法不同,采用基于关键特征的聚类算法(KFC).首先从搜索引擎返回结果的关键词里选择重要的词作为关键特征,然后通过分析特征间的关系对特征聚类,最后基于特征聚类结果实现文档的聚类.通过对实验结果的测试表明了算法的有效性.

Abstract: To solve the problem that users of web search engines are often forced to sift through the long ordered list of document, a new key-feature clustering (KFC) algorithm was presented to help locate the valuable search results that the users really needed, which was different from VSM. The algorithm firstly extracted some key features from the keywords in the search results. Then the relationships between key features were analyzed and features were clustered. Finally, the documents were clustered based on these clusters of key features. The algorithm was tested and validated by the results of experiments.
