Arun Qamra, Belle Tseng, Edward Y. Chang
2006 Proceedings of the 15th ACM international conference on Information and knowledge management - CIKM '06  
We wish to extract such temporal discussions, or stories, occurring within blogger communities, based on some query keywords.  ...  We propose a Content-Community-Time model that can leverage the content of entries, their timestamps, and the community structure of the blogs, to automatically discover stories.  ...  RELATED WORK We present related work here in four parts: 1) blog mining research, 2) use of probabilistic graphical models for content and relation analysis, 3) temporal mining, and 4) Web search result  ...

Ranking of evolving stories through meta-aggregation

Juozas Gordevicius, Francisco J. Estrada, Hyun Chul Lee, Periklis Andritsos, Johann Gamper
2010 Proceedings of the 19th ACM international conference on Information and knowledge management - CIKM '10  
We evaluate the framework using both objective and subjective criteria, and discuss the selection of clustering method and similarity measure that lead to the best ranking results.  ...  First, the mining step discovers metastories, which constitute meaningful groups of similar stories that occur at arbitrary points in time.  ...  We use story clusters containing news articles as well as related blogs provided by a state-of-the-art platform for news and social media aggregation called Thoora.  ...
