Impact Analysis of the Person in Topic Event Mining

Impact analysis of the person can help us to understand the role that this individual plays and the development of the event. This paper focuses on a study of persons’ impact on events. The problem is addressed by exploiting concepts coming from physics and using indicators typically exploited in stock market analysis. We assess person’s impact on a specific topic event by expressing ‘momentum’ and referring to a key period as the interval when this impact is profound and is kept relatively stronger. Key features of the model (viz. the impacts and key periods) are estimated by the combination of Moving Average Convergence Divergence (MACD) and MACD histogram drawn from stock analysis. Experimental results reported for four well-known topic events in China show that the model could achieve desirable result in analyzing person’s impact on the topic event.
