基于智能的网页信息提取系统的研究与设计

Research on Web information extraction system based on intelligence and its design

随着Internet的迅速发展,为人们提供了大量的信息,但这些信息都包含在网页中,为了使用这些信息数据,需要将数据从网页中提取出来.本文介绍了一种新的基于智能的网页信息提取系统EIES,通过对RoadRunner的改进和利用,在提取过程中不需人工干预,实现了信息提取的智能化.实验表明,该系统能够更准确、更有效地分类相似网页和提取网页信息.

Along with the Internet rapid development, a mass of information is supplied for people, but all these information is in the Web pages. In order to make use of these information data, it＇s needed to extract the data from the pages. This paper presents a new Web information extraction system based on intelligence-EIES. Through improving and using RoadRunner, it realizes the information extraction intellectualization without any manual work in the extraction process. The experiment indicates that this system can be more accurate and more effective to classify similar pages and extract web information.
