垂直搜索引擎应用中的若干策略探讨——以12580餐饮垂直搜索为例

Research on the Policy of Vertical Search Engine Application——An Example of 12580 Search Engine

首先概述垂直搜索引擎的有关研究,结合通用搜索引擎分析垂直搜索引擎的一些特点和应用,然后结合实际的开发应用从提高查准率、提高查询速度、提高信息采集效率、控制信息采集质量等角度进行分析和探讨,在实例探讨中结合12580网络信息采集的餐饮垂直搜索原型系统提出信息采集、信息更新、信息抽取等实际应用领域中的若干策略。

This paper introduces research on vertical search engines, analyzes its features and applications comparing with general search engines. Practical problems such as improving precision ratio, searching speed, information acquisition efficiency and controlling information acquisition quality are also discussed. With the catering vertical search prototype in 12580 information acquisition system as a reference, some application strategies about information acquisition, information updates and information extraction are proposed.
