by Xavier Llorà, Noriko Imafuji Yasui, David E. Goldberg (2006). Proceedings of the International Conference on Weblogs and Social Mining (ICWSM 2007). Also as IlliGAL TR. No. 2006026. Link to the PDF. Abstract The blogsphere is a valuable source of information. From simple topic analysis in the blogosphere—what’s hot—to harvesting and analyzing valuable market trends—what product and features are suggested—require a tight integration of computer- and human-based analysis capabilities.

Delineating Topic and Discussant Transitions in Online Collaborative Environments

by Noriko Imafuji Yasui, Xavier Llorà, and David E. Goldberg (2006). Illinois Technical Report No. 2006025. Link to the PDF. Abstract In this paper, we propose some methodologies for delineating topic and discussant transitions in online collaborative environments, more precisely, focus group discussions for product conceptualization. First, we propose KEE (Key Elements Extraction) algorithm, an algorithm for simultaneously finding key terms and key persons in a discussion. Based on KEE algorithm, we propose approaches for analyzing two important factors of discussions: discussion dynamics and emerging social networks....

Adaptable Extraction of Key Elements from Weblogs

by Xavier Llorà, Noriko Imafuji Yasui, David E. Goldberg (2006) Abstract This paper proposes AKEE (Adaptable Key Elements Extraction) algorithm for web-log (blog, for short) mining. AKEE enables us to identify significant information in various blog components (e.g., a blog post, a series of blog posts, a set of series of blog posts, etc.). Illinois Technical Report No. 2006024.
