Abstract

Opinion propagation analysis in online forum threads is a relatively new research field emerging in the context of the increasing popularity of forums. Many changes occur over time in online forum threads since new users intervene in the discussion and express their opinions. In this paper, we propose a novel task in the analysis of opinion propagation in online forum threads, i.e. the modeling of post-level sentiment evolution in online forum threads. This task consists in the analysis of post-level sentiment evolution in an online forum thread in order to obtain a simplified model of this evolution. Based on opinion mining, graph theory, and post-level sentiment analysis, our method comprises five steps: removal of posts containing only facts, post-level sentiment identification, removal of posts with neutral sentiment, aggregation of parent-child vertices, and aggregation of sibling vertices. We evaluate the proposed method on real-world forum threads, and the results of our experiments are presented in the visualization interfaces.
