Sentiment analysis is a growing field of research, driven by both commercial applications and academic interest. In this paper, we explore multiclass classification of diary-like blog posts for the sentiment dimensions of valence and arousal, where the aim of the task is to predict the level of valence and arousal of a post on a ordinal five-level scale, from very negative/low to very positive/high, respectively. We show how to map discrete affective states into ordinal scales in these two…

Community-Based Weighted Graph Model for Valence-Arousal Prediction of Affective Words

This study proposes a community-based weighted graph model that can select seeds which are both similar to and have similar ratings with each unseen word to form a community (subgraph) so that its VA ratings can be estimated from such high-quality seeds using a weighted propagation scheme.

A locally weighted method to improve linear regression for lexical-based valence-arousal prediction

This study proposes the use of a locally weighted linear regression (LWLR) model to predict the valence-arousal ratings of affective words and shows that the proposed method achieved better performance for VA word prediction.

Chinese EmoBank: Building Valence-Arousal Resources for Dimensional Sentiment Analysis

This study aims to build a Chinese valence-arousal resource called Chinese EmoBank, the first Chinese dimensional sentiment resource featuring various levels of text granularity and evaluate the proposed resource using different categories of classifiers such as lexicon-based, regression- based, and neural-network-based methods.

A Two-Dimensional Sentiment Analysis of Online Public Opinion and Future Financial Performance of Publicly Listed Companies

The empirical results tended to support the two hypotheses that there is a positive association between the valence or arousal-augmented valence of online public opinion about the listed companies and their future financial performance.
