摘要
社交网络成为现在人们生活的一种重要方式,越来越多的人选择通过社交网络表达观点、抒发心情。在海量的数据下,快速发现讨论的内容得到越来越多的研究者的关注,随即出现了大量的话题发现算法。在大规模新浪微博数据环境下,针对3种经典分布式话题发现算法,结合社交网络平台的特点提出了分析性能的测试方案,并根据测试方案比较与分析了3种算法的性能,指出了各算法的优缺点,为后续应用提供参考。
Social network has become a way of life,therefore more and more people choose social network to express their views and feelings.Quickly find what people are talking about in big data gets more and more attention.And a lot of related methods of topic detection spring up in this situation.The performance analysis project was proposed based on the characteristics of social network.According to the project,the performances of some typical topic detection algorithms were tested and compared in large-scale data of Sina Weibo.What’s more,the advantages and disadvantages of these algorithms were pointed out so as to provide references for later applications.
