@misc{asur2010predicting, abstract = {In recent years, social media has become ubiquitous and important for socialnetworking and content sharing. And yet, the content that is generated fromthese websites remains largely untapped. In this paper, we demonstrate howsocial media content can be used to predict real-world outcomes. In particular,we use the chatter from Twitter.com to forecast box-office revenues for movies.We show that a simple model built from the rate at which tweets are createdabout particular topics can outperform market-based predictors. We furtherdemonstrate how sentiments extracted from Twitter can be further utilized toimprove the forecasting power of social media.}, author = {Asur, Sitaram and Huberman, Bernardo A.}, file = {asur2010predicting.pdf:asur2010predicting.pdf:PDF}, groups = {public}, interhash = {538607d6d5da7946a0c5a2114a7c44f5}, intrahash = {9c23c0465529a60d9540ee29e74856f1}, note = {cite arxiv:1003.5699}, timestamp = {2010-11-09 10:12:57}, title = {Predicting the Future with Social Media}, url = {http://arxiv.org/abs/1003.5699}, username = {dbenz}, year = 2010 } @inproceedings{wagner2010wisdom, abstract = {Although one might argue that little wisdom can be conveyed in messages of 140 characters or less, this paper sets out to explore whether the aggregation of messages in social awareness streams, such as Twitter, conveys meaningful information about a given domain. As a research community, we know little about the structural and semantic properties of such streams, and how they can be analyzed, characterized and used. This paper introduces a network-theoretic model of social awareness stream, a so-called \tweetonomy", together with a set of stream-based measures that allow researchers to systematically define and compare different stream aggregations. We apply the model and measures to a dataset acquired from Twitter to study emerging semantics in selected streams. The network-theoretic model and the corresponding measures introduced in this paper are relevant for researchers interested in information retrieval and ontology learning from social awareness streams. Our empirical findings demonstrate that different social awareness stream aggregations exhibit interesting differences, making them amenable for different applications.}, author = {Wagner, C. and Strohmaier, M.}, booktitle = {Proc. of the Semantic Search 2010 Workshop (SemSearch2010)}, file = {wagner2010wisdom.pdf:wagner2010wisdom.pdf:PDF}, groups = {public}, interhash = {02c222a4f9abd5964ea61af034769af4}, intrahash = {2f96232a648d4fd1617c389d899f3d2b}, location = {Raleigh, NC, USA}, month = {april}, timestamp = {2010-04-19 08:03:47}, title = {The Wisdom in Tweetonomies: Acquiring Latent Conceptual Structures from Social Awareness Streams}, url = {http://mstrohm.wordpress.com/2010/04/17/on-taxonomies-folksonomies-and-tweetonomies/}, username = {dbenz}, year = 2010 }
