DialogXL: All-in-One XLNet for Multi-Party Conversation Emotion Recognition

Recognizing thoughts in conversation is a process wherever current language versions face several complications. They are not tailored to multi-party dialogues and do not encode intra- and inter-speaker dependencies. Also, enter size is constrained, and the info in distant historical utterances might be misplaced. A current review tries to defeat these issues.

It utilizes flexible and memory-preserving utterance recurrence to keep the states of historical utterances and reuse them whilst determining a question utterance. As an alternative of computing focus weights between text, the novel model utilizes dialog-conscious self-focus, which differentiates reception fields and party roles, particularly neighborhood self-focus, world-wide self-focus, speaker self-focus, and listener self-focus. The substantial experiments show that the advised model outperforms all the baselines.

This paper provides our pioneering energy for emotion recognition in conversation (ERC) with pre-trained language versions. Not like standard files, conversational utterances surface alternately from unique get-togethers and are ordinarily structured as hierarchical structures in preceding function. This sort of structures are not conducive to the software of pre-trained language versions such as XLNet. To deal with this problem, we suggest an all-in-one particular XLNet model, particularly DialogXL, with improved memory to keep longer historical context and dialog-conscious self-focus to offer with the multi-party structures. Precisely, we very first modify the recurrence mechanism of XLNet from section-stage to utterance-stage in purchase to better model the conversational information. 2nd, we introduce dialog-conscious self-focus in replacement of the vanilla self-focus in XLNet to capture handy intra- and inter-speaker dependencies. Considerable experiments are performed on four ERC benchmarks with mainstream versions presented for comparison. The experimental outcomes show that the proposed model outperforms the baselines on all the datasets. A number of other experiments such as ablation review and mistake analysis are also performed and the outcomes affirm the purpose of the essential modules of DialogXL.
