摘　　要：针对接触屏信息交互量较大,导致检索精准度低的问题,设计了基于Tag-rank的接触屏信息化跨媒体检索系统。基于跨媒体交互结构、动态接触屏信息化存储器和跨媒体检索引擎,完成系统硬件设计。在此基础上,通过Tag-rank方法计算词项关联度,抽取跨媒体关键词,将图像和文本转换到同构数据子空间,构建图像、文本的索引键值,获取两类检索结果,完成基于Tag-rank的接触屏信息化跨媒体检索系统设计。由测试结果可知,所设计系统的图像、文本检索精准度最高分别为0.95和0.97,具有良好的检索效果。In response to the problem of high interaction volume of contact screen information,which leads to low retrieval accuracy,a Tag⁃rank based contact screen information cross media retrieval system was designed.Based on the cross media interaction structure,dynamic contact screen information storage,and cross media search engine,complete the system hardware design.On this basis,the Tag⁃rank method is used to calculate the term association degree,extract cross media keywords,convert images and text into isomorphic data subspaces,construct index key values for images and text,and obtain two types of search results.The design of the contact screen information cross media search system based on Tag⁃rank is completed.According to the test results,the highest image and text retrieval accuracy of the designed system is 0.95 and 0.97,respectively,indicating good retrieval performance.
