基于人机交互的数字图书相关联查询系统设计

Design of digital book incidence query system based on human-computer interaction

当前使用的数字图书查询系统中,由于系统发出的查询指令不明确,导致存在查询速度慢、查全率低的问题。为此,文中从硬件、数据库和软件三个方面,利用人机交互技术实现对数字图书相关联查询系统的优化设计。在硬件方面主要是对系统的服务器、扫描机、控制器等设备进行改装与优化,并将采集的数字图书数据按照类别存储在系统数据库中。在硬件设备和数据库的支持下,利用人机交互技术输入查询关键词,并通过收集数字图书信息、处理数字图书文本、计算数字图书关联度和生成查询索引4个步骤,实现系统的数字图书相关联查询功能。通过系统测试得出结论:与传统查询系统相比,设计的查询系统平均查询耗时为0.36 s,且查全率为99.7%,具有一定的应用价值。

The currently⁃used digital book query system has the problems of slow query speed and low recall ratio due to the unclear query instructions issued by the system.Therefore,the human⁃computer interaction technology is adopted to realize the optimization design of a digital book incidence query system in three aspects of hardware,database and software.In terms of hardware,the server,scanner,controller and other equipments of the system are modified and optimized,and the collected digital book data are stored in the system database according to categories.With the support of hardware equipments and database,the query keywords are input by means of the human⁃computer interaction technology,and the digital book incidence query function of the system is realized through four steps:collecting digital book information,processing digital book text,calculating digital book correlation degree and generating query index.The system testing results show that,in comparison with the traditional query system,the average query time⁃consuming of the designed query system is 0.36 s,and the recall ratio is 99.7%.It has a certain application value.
