Method for Evaluating Participants' Roles in Online Text Discussion Using Network Analysis

Abstract

We propose a method for evaluating participants’ roles in online text discussion using network analysis of chat log data. In our method, we use log data to construct a statement network indicating the relativity of the statements. We evaluate the participants’ role by calculating four types of point centralities. Experiments have been conducted to evaluate our method. The results from our method closely correspond to participants’ peer assessment data. This indicates that the proposed method is effective.
