基于元搜索的信息获取是网络信息采集中重要且行之有效的手段之一,得益于近些年搜索引擎快速发展,这种方式的信息获取具有覆盖面广、简单操作等优点.探讨基于元搜索的信息采集平台的实现方法,对获取到的海量异构信息实现归一化存储,并实现自动热点聚成及热点呈现.实验证明,该平台在信息获取中有着不错的效果,还在信息汇总、热点融合等功能上为用户提供高效、便捷的操作手段.%Meta-search based information acquisition is one of the important and effective ways in network information acquisition, thanks to the rapid development of search engines in recent years, information acquisition in this way has the superiorities of wide coverage, simple operation and so on. This article expounds meta-search based information acquisition platform implementations, acquires a mass of heterogeneous information to a normalised storage, and automatically clusters them into hot spots and shows the hot spots view. Experiments show that the platform has good achievement of information acquisition in effect, and provides users efficient and convenient operations such as info aggregation and hot spots fusion.
