铁路共享信息搜索引擎的设计

The Design of Search Engine for Railway Information Shared System

讨论了搜索引擎的基本组成模块,以及各模块的作用和相互关系.并根据铁路信息的特点给出了适合铁路共享信息搜索的引擎设计方案.设计所需技术主要有:分类检索技术、搜索引擎技术、自然语言理解技术等.主要目标是使得铁路信息资源共享平台建立以后,该搜索引擎能够提供全路范围内的各种共享数据的分类索引和查询,用户还可以通过智能化的用户界面,查找到所需数据的存放位置和存放方法.

Illustrating the constituted modules of search engine and the relation of these modules. The fundamental algorithms are reconstructed according to the characteristics of the railway information. The design needs the following technologies: natural language processing technology, search robot technology and the Chinese and English index technology. The purpose of design is to provide users with a quick, efficient and exact search tool at the railway information shared system. This search engine is able to provide the indexes of all the railway information, and users could search the needed data through the intelligent user interface.
