Context-Aware Siamese Networks for Efficient Emotion Recognition in Conversation
This work addresses emotion recognition in conversation, an important challenge in human-computer interaction, with an incremental improvement over previous methods.
The paper tackled emotion recognition in conversation by proposing a context-aware Siamese network with metric learning, achieving a state-of-the-art macro F1 score of 57.71 on the DailyDialog dataset.
The advent of deep learning models has made a considerable contribution to the achievement of Emotion Recognition in Conversation (ERC). However, this task still remains an important challenge due to the plurality and subjectivity of human emotions. Previous work on ERC provides predictive models using mostly graph-based conversation representations. In this work, we propose a way to model the conversational context that we incorporate into a metric learning training strategy, with a two-step process. This allows us to perform ERC in a flexible classification scenario and to end up with a lightweight yet efficient model. Using metric learning through a Siamese Network architecture, we achieve 57.71 in macro F1 score for emotion classification in conversation on DailyDialog dataset, which outperforms the related work. This state-of-the-art result is promising regarding the use of metric learning for emotion recognition, yet perfectible compared to the microF1 score obtained.
