Demarcating Endogenous and Exogenous Opinion Dynamics: An Experimental Design Approach

no code implementations11 Feb 2021 Paramita Koley, Avirup Saha, Sourangshu Bhattacharya, Niloy Ganguly, Abir De

The networked opinion diffusion in online social networks (OSN) is often governed by the two genres of opinions - endogenous opinions that are driven by the influence of social contacts among users, and exogenous opinions which are formed by external effects like news, feeds etc.

A graphical framework to detect and categorize diverse opinions from online news

no code implementations WS 2016 Ankan Mullick, Pawan Goyal, Niloy Ganguly

This paper proposes a graphical framework to extract opinionated sentences which highlight different contexts within a given news article by introducing the concept of diversity in a graphical model for opinion detection. We conduct extensive evaluations and find that the proposed modification leads to impressive improvement in performance and makes the final results of the model much more usable.
