Design of Tag-rank based cross media retrieval system for contact screen informatization
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.
