摘要
为了从海量数据空间中快速、准确获取用户所需Web信息,设计并实现了一个基于分类本体的Web信息集成系统。设计了Web信息自动归类算法,研究了基于分类本体的异构分类体系集成方法,实现了异构分类体系的合并,形成逻辑统一的、基于分类的Web集成视图。通过Web数据抽取机制以及Web信息分类技术实现了检索结果的分类和层次化展示,方便用户浏览、快速定位所需信息。
A web information integration system based on classification ontology is designed and implemented to obtain the web information what users need among magnanimous data space fast and accurately. The arithmetic of web information classification is designed and the integrated method based on classification ontology is studied to merge the isomerism classification system. The logical web integration view based on classification is formed. Result can be classified into groups and displayed hierarchically by web information extraction mechanism and users obtain what they need on WWW fast, which has the great significance for the convenience of browsing and the fast localization.
