Discovering geographical topics in the twitter stream

Liangjie Hong, Amr Ahmed, Siva Gurumurthy, Alexander J. Smola, Kostas Tsioutsiouliklis
2012 Proceedings of the 21st international conference on World Wide Web - WWW '12  
In this paper we focus on Twitter and present an algorithm by modeling diversity in tweets based on topical diversity, geographical diversity, and an interest distribution of the user.  ...  It is a challenge task to discover topics and identify users' interests from these geo-tagged messages due to the sheer amount of data and diversity of language variations used on these location sharing  ...  In addition, we thank Twitter to provide the dataset and the permission for publication of this work. We also appreciate the reviews from anonymous reviewers.  ...
