基于DOM树的视频元数据抽取系统
Video Metadata Extraction System Based on DOM Tree
摘要
Abstract
Most of the extraction methods mainly focus on the extraction of the subject information block, and pay no attention on the individual information piece. A video metadata extraction system based on DOM tree is proposed to solve this problem. Combining with the node type of Web DOM tree, it extracts the metadata of Web pages thorough individual subject information block by improving the links filter functions of Heritrix and queue management strategy of URL. Experimental results show that the average precision ratio of Web page and the average extraction ratio of the system are 95.7% and 98.4%, greatly higher than the similar systems.关键词
