Prototype system for visualizing review text using evaluative expression dictionaries

Abstract

We propose a system that can score online reputation text for a given attribute, e.g., design and portability, in a certain category, e.g., mp3 players and laptops. Additionally, we visualize scored results as an interactive system. The scoring system has evaluative expression dictionaries created in advance using reviews. They comprise evaluative values that determine the attribute-wise polarity of evaluative expressions: good or bad. Our system analyzes online reputation using the evaluative expression dictionaries, and then outputs the scores of the reputation. The system helps users to ascertain a reputation easier than merely by reading through textual information. ?? 2014 Springer International Publishing Switzerland.
