Twitter Topic Summarization by Ranking Tweets using Social Influence and Content Quality

Yajuan Duan, Zhimin Chen, Furu Wei, Ming Zhou, Heung-Yeung Shum
2012 International Conference on Computational Linguistics  
In this paper, we propose a time-line based framework for topic summarization in Twitter. We summarize topics by sub-topics along time line to fully capture rapid topic evolution in Twitter.  ...  Moreover, we show how the content quality of tweets and the social influence of users effectively improve the performance of measuring the salience of tweets.  ...  We randomly select 3,000 tweets from an additional tweet corpus for content quality training and evaluation. One of two labels, H(high quality) and L(low quality), are assigned to every tweet.  ...
