Proceedings of the 7th International AAAI Conference on Weblogs and Social Media
The social and community driven aspects of our digital lives continue to rapidly increase, resulting in transformative behaviors and, significantly, publishing and distributing huge amounts of fascinating data. The seventh meeting of the International AAAI Conference on Weblogs and Social Media (ICWSM-13) held in Cambridge, Massachusetts, promised to be a benchmark year for ICWSM. Thanks to the enthusiastic participation of our community, we received a record number of submissions, with a growth of 50 percent over the previous year. More than the quantity, however, the high quality of the submitted papers is the truest evidence that ICWSM is maturing in its role as a premier venue for social media research.
We study information dissemination in Twitter. We present an analysis of two important characteristics of so called “ retweet cascades”: retweet count and “show” count, i.e., number of users that receive the tweet in their feed. We show that these two measures behave differently. We describe three models that are aimed to predict the audience size of a tweet: first one utilizes only the data available at the moment of the initial tweet, the second one utilizes the spread of the cascade up to some moment while the third one is an “online prediction”.
