Identification and Visualization of Emerging Trends from Blogosphere

Makoto Uchida, Naoki Shibata and Susumu Shirayama

We propose a method for tracking emerging trends from weblogs, by a hybrid approach of semantic-based and citation-based. In the present method, we form a citation network of the blogosphere by regarding entries as nodes and track-backs as edges, and identify groups (communities) of entries by topological clustering on the network. Then we assign featured terms which represent a topic of each community by applying a TF-IDF based technique. The overall results are visualized by graph drawing. Applying the method to a test collection of Japanese weblogs, we confirm that the proposed method works successfully.
