TL;DR
This paper introduces an emoji-based co-attention network that models the mutual emotional semantics between text and emojis in microblog sentiment analysis, significantly improving accuracy over existing methods.
Contribution
It presents a novel co-attention mechanism integrating text and emojis with a squeeze-and-excitation CNN to better capture emotional semantics.
Findings
Significantly outperforms baseline models in sentiment analysis accuracy.
Effectively captures emotional semantics of emojis and text interaction.
Enhances sensitivity to emotional features through squeeze-and-excitation blocks.
Abstract
Emojis are widely used in online social networks to express emotions, attitudes, and opinions. As emotional-oriented characters, emojis can be modeled as important features of emotions towards the recipient or subject for sentiment analysis. However, existing methods mainly take emojis as heuristic information that fails to resolve the problem of ambiguity noise. Recent researches have utilized emojis as an independent input to classify text sentiment but they ignore the emotional impact of the interaction between text and emojis. It results that the emotional semantics of emojis cannot be fully explored. In this paper, we propose an emoji-based co-attention network that learns the mutual emotional semantics between text and emojis on microblogs. Our model adopts the co-attention mechanism based on bidirectional long short-term memory incorporating the text and emojis, and integrates a…
