Design and implementation ofa text retrieval tool based on video content searching

在足球赛事视频的应用背景下,分析了面向视频场景内容检索的文本解析关键技术,设计并实现了面向视频场景内容检索的文本解析工具。该工具利用中文分词技术分割自然语言文本,通过汉语语法规则提取关键词,采用加权算法对关键词排序,并将关键词映射到知识表达集,从而获得关键词的语义信息,完成文本解析。实验结果表明,该工具能够满足自然语言文本的视频检索需求。

In the background of application for soccer video, the paper analyzes key technologies on the text retrieval tool for video content, and designs and implements a text retrieval tool for video content. Firstly, the tool segment natural language text by using Chinese word segmentation, extract key words by Chinese grammar rules from the segmentation of natural hmgoage text, sort keywords by using the weighted algorithm, map the keywords to knowledge expression set to gaining semantic information of keywords and completing text pal.＇sing, and finally application of text retrieval tool for video search is showed by using the web page. The experiment results show that the text analysis tool for video content designed and implemented in the paper meets the demand for searching video by natural language text.
