OpinioNetIt: A structured and faceted knowledge-base of opinions

Abstract

We propose a demonstration of our system, OpinioNetIt, a structured, faceted, knowledge-base of opinions, and its use in political analysis. OpinioNetIt consists of information about people, topics and opinions in the form of triples, indicating the opinion of a person on a topic. Our focus is on acquiring opinions held by various stakeholders on politically controversial topics. Our system can be used for various kinds of analyses such as generating heat maps showing political bias, identifying flip-flopping politicians, and identifying dissenters, etc. In this demonstration proposal, we give a brief overview of our system and the proposed demonstration.
