摘要
分析了Web文档的结构特征,并利用知识树快速高效等特征,设计了Web文档知识树;基于Web文档知识树结构,提出了构建Web文档知识树的构造算法、创建知识结点算法以及知识树访问算法.并对上述算法作了分析和评价,说明了这些算法对提高Web信息检索的准确率以及信息查找的速度是有益的.
The structural features of web documents have been analyzed and the structure of web knowledge tree which has fast and efficient features has been designed in this paper. Based on the structure of knowledge tree, some relevant algorithms are proposed, such as knowledge tree construction algorithm, creating knowledge tree node algorithm and visiting knowledge tree algorithm. The analysis and evaluation of these algorithms have showed that they are useful for improving the web information retrieval accuracy and speed.
