摘要 随着商务贸易电子化、企业和政府事务电子化、信息处理产业化等的发展,产生了大规模的Web数据源,由于这些Web数据源的动态性、多元性、无序性、模式化等特点,特别是数据库的半结构化,加大了数据处理或数据挖掘的难度,知识发现应运而生,为自动化和智能化地把海量的数据转化为有用的知识提供了手段。文章从半结构化数据的3种分布方式中,探索出半结构化数据的3种模型,进而提出了半结构化数据知识发现的算法及方法。 According to the three ways of data distribution, the author discusses three data models of semi-structured data of Web-based resource. He furthermore puts forward to the arithmetic and method of knowledge discovery from the semi-structured data of Web-based resource.
