Abstract

Personality Recognition in Conversations (PRC) is a task of significant interest and practical value. Existing studies on the PRC task utilize conversation inadequately and neglect affective information. Considering the way of information processing of these studies is not yet close enough to the concept of personality, we propose the SAH-GCN model for the PRC task in this study. This model initially processes the original conversation input to extract the central speaker feature. Leveraging Contrastive Learning, it continuously adjusts the embedding of each utterance by incorporating affective information to cope with the semantic similarity. Subsequently, the model employs Graph Convolutional Networks to simulate the conversation dynamics, ensuring comprehensive interaction between the central speaker feature and other relevant features. Lastly, it heuristically fuses central speaker features from multiple conversations involving the same speaker into one comprehensive feature, facilitating personality recognition. We conduct experiments using the recently released CPED dataset, which is the personality dataset encompassing affection labels and conversation details. Our results demonstrate that SAH-GCN achieves superior accuracy (+1.88%) compared to prior works on the PRC task. Further analysis verifies the efficacy of our scheme that fuses multiple conversations and incorporates affective information for personality recognition.

基于融合多对话和语篇级情感的启发式人格识别
对话中的人格识别(PRC)是一项具有重大意义和实用价值的任务。现有的关于人格识别任务的研究对对话的利用不够充分,忽略了情感信息。考虑到这些研究的信息处理方式还不够贴近人格的概念,我们在本研究中提出了针对 PRC 任务的 SAH-GCN 模型。该模型对原始对话输入进行初步处理,以提取说话者的中心特征。利用对比学习(Contrastive Learning)技术,该模型会结合情感信息不断调整每句话的嵌入,以应对语义相似性问题。随后,该模型采用图卷积网络来模拟对话动态,确保中心发言人特征与其他相关特征之间的全面互动。最后,它启发式地将涉及同一发言人的多个对话中的中心发言人特征融合为一个综合特征,从而促进个性识别。我们使用最近发布的 CPED 数据集进行了实验,该数据集是包含感情标签和对话细节的个性数据集。结果表明,在 PRC 任务中,SAH-GCN 的准确率(+1.88%)优于之前的研究。进一步的分析验证了我们融合多个对话和情感信息的人格识别方案的有效性。
