摘要
首先给出基于事件的新闻报道分析技术相关概念的定义,并提出一个基于事件的新闻报道分析技术框架;然后从四个方面介绍了基于事件的新闻报道分析中的关键技术,包括事件探测、事件追踪、事件相关文档摘要和事件RSU检索。对一些关键技术进行了分类和评价,剖析其优势及不足,通过对各种方法的分析和比较,提出了一些改进的方法和建议。最后展望了未来基于事件的新闻报道分析技术的发展方向。
The definitions relevant to event based analyzing techniques in news report were firstly presented and a frame of event based analyzing techniques in news report was proposed, and then key techniques were discussed from four aspects： event detection, event tracking, event related document summarization and event RSU retrieval. Some key techniques were classified and evaluated, and their advantages and disadvantages were analyzed. Based on the analysis and comparison, the improved methods and suggestions were presented. At last, the problems of current research were discussed and the future directions of event based analyzing techniques in news report were pointed out.
