Research on Key Technologies of VSE System and Its Application in the Bidding Field of Communication Industry

摘要: 本文首先对通信行业招投标领域信息获取的弊端进行分析，总结出用户当前存在三大需求，然后结合对比人工目录分类、文本处理和智能搜索引擎等技术，提出采用垂直搜索引擎系统实现行业应用的设计路线；并对大数据垂直搜索引擎系统的体系架构、信息采集、索引建立进行了详细设计，最后实现该系统并在通信行业招标领域进行推广使用。结果表明，本文提出的面向行业垂直搜索引擎系统具有良好的适用性，能够满足通信及其他行业的招标信息获取、精准分发和推送需求。

Abstract: This paper first analyzes the disadvantages of information acquisition in the field of bidding in the communication industry, summarizes the three current needs of users, and then proposes the de-sign route of using vertical search engine system to realize the industry application by comparing the technologies of artificial directory classification, text processing and intelligent search engine. The architecture, information collection and index establishment of big data vertical search engine system are designed in detail. Finally, the system is implemented and used in the field of communication industry bidding. The results show that the industry-oriented vertical search en-gine system proposed in this paper has good usability and can meet the requirements of bidding information acquisition, accurate distribution and push of communication and other industries.
