面向KMS的Web信息采集机制研究

Research on Web Gathering Mechanism for Knowledge Management System

Web是知识管理系统（KMS）信息采集的重要来源之一，但其数据的庞杂无序和半结构化特性给信息采集工作造成了一定难度。文章对Web信息采集机制，特别是HTML结构特征分析法进行了探讨，并结合采集机制研究，以建立企业名录信息库为例，说明采集系统如何最大限度地提高KMS基础信息采集的能力。

Web is one of the important sources for KMS information collection. HoWeVer, web information is large in amount, disordered and semistructured, which brings difficulties for information collection. This paper discussed the mechanism of Web information collection, especially discussed the HTML structure characteristic analysis method. Combining to collection mechanism, taking the establishment of business enterprise record database as an example, the paper explained how the system can improve the ability of KMS information collection.
