基于标签的垂直搜索研究及在视频搜索中的应用

Study on Label-based Vertical Search and Applications on Video Search

分析了针对视频资源进行标签抽取的信息抽取机制,以及利用垂直搜索引擎的特点进行数据处理的方法,对于农业视频资源搜索准确度难以提高等问题进行了优化,并应用于农业搜索中,对搜索结果进行了测试以及与通用视频搜索进行了对比。实验结果表明,在农业领域的视频垂直搜索结果更加精准清晰,用户友好度更高。

The resources tab for the extraction of video information extraction mechanism and the characteristics of using vertical search engines for data processing method are analyzed.Issues about search accuracy of agriculture video resources is difficult to improve are optimized and applied to agricultural search.The search results were tested and were compared with general video search.Experimental results show that the videos in agriculture vertical search results are more precise and have a higher user-friendly degree.
