摘要:

社交媒体(例如Twitter)的日益普及允许用户轻松地彼此分享信息,并通过表达自己对各种主题的看法来影响他人。在这项工作中,我们提出了一个无监督的\emph{tri-clustering}框架,分析用户级和推文级的情感,通过共同聚类的三方图。该框架的一个引人注目的特点是,推文,用户和功能的情感聚类的质量可以通过联合聚类相互提高。我们进一步研究在线框架中用户级情感和潜在特征向量的演变,并设计一种高效的在线算法,用新到达的数据顺序更新推文、用户和特征的集群。在线框架不仅提供了更好的质量的动态用户级和推文级情感分析,但也提高了计算和存储效率。我们验证了2012年11月加州选票Twitter数据的有效性和效率的方法。

英文摘要:

The growing popularity of social media (e.g, Twitter) allows users to easily share information with each other and influence others by expressing their own sentiments on various subjects. In this work, we propose an unsupervised \emph{tri-clustering} framework, which analyzes both user-level and tweet-level sentiments through co-clustering of a tripartite graph. A compelling feature of the proposed framework is that the quality of sentiment clustering of tweets, users, and features can be mutually improved by joint clustering. We further investigate the evolution of user-level sentiments and latent feature vectors in an online framework and devise an efficient online algorithm to sequentially update the clustering of tweets, users and features with newly arrived data. The online framework not only provides better quality of both dynamic user-level and tweet-level sentiment analysis, but also improves the computational and storage efficiency. We verified the effectiveness and efficiency of the proposed approaches on the November 2012 California ballot Twitter data.
