随着Internet的飞速发展.web已经发展成为一个巨大的信息资源库,但是目前web数据大都以HTML形式出现,这使得应用程序无法直接利用Web上的海量信息.针对这一问题,出现了Web信息采集技术.该文对信息采集技术进行了探讨,并在此基础上实现了一个基于web的新闻采集系统,该系统可根据用户使用正则表达式编写的采集规则快速而精确的采集目标网页中的信息,保存在本地数据库中,用于内部使用或外网发布.

With the rapid development of Internet, Web has become a huge, distribution and sharing of information resources library. But most of Web-data are represented with HTML. So the massive Web-data are not available to the applications. For this purpose, the technology of Web-information extraction appeared.In this thesis, we discussed the technology of information extraction, and on this basis to achieve a Web-based news extraction system,which users can use regular expressions to make extraction rule and use it to extarct the Web-information quickly and accurately, save in local database, for internal use or released them to the Intemet.
