摘要
文章首先给出了基于话题检测实现论坛热门话题发现的基本方法,再针对论坛文本稀疏性造成的漏报率高的问题,提出了基于主题扩展的话题发现方法,最后设计并实现了一个BBS热点话题发现原型系统。实验结果表明文章提出的方法和系统可以有效地监控校园论坛上出现的热门话题。
The basic method of bulletin board hot topic finding was given based on the realization of topic detection and a topic finding method was proposed based on topic extension in connection with the high rate of false negatives caused by the sparsity of bulletin board text. Finally a primitive type system of BBS hot topic finding was designed and realized. The experimental results showed that the method and the system proposed can effectively monitor the hot topics appeared in BBS.
