有效地检索HTML文档

ＷＷＷ上的资源大多以ＨＴＭＬ格式的文档存储,同普通文档不同,ＴＨＭＬ文档的标签特性使得它具有一定的结构我们采取了一种检索,它扩展了传统的传统检索,利用ＨＴＭＬ文档结构提高了在ＷＷＷ环境下的检索和率。本文介绍了ＨＴＭＬ的结构以及传统的向量空间信息检索提出了运用聚族方法为标符合分组;最后详细讨论了如何利用文棣结构扩展加权架,使得检索词能更贴切地描述文档,以提高检索的准确性。

EFFECTIVELY RETRIEVE HTML DOCUMENTS

The information resources in WWW are mostly stored as HTML. Unlike norm al documents, the HTML documents is structured. In this paper, we propose a meth od for making use of the structure to effectively retrieve HTML documents. This method derived from the traditional information retrieval. First, we describe th e structure of HTML and the traditional IR based on the vector space model. Then we propose our extending weighting schema and tags classes. Finally we provide the conclusion and future work.
