AI总结:

E3VA通过情感分析和自然语言处理提升虚拟对话代理的情感表达性,增强用户体验和对话质量。

摘要:

随着生成式AI和大语言模型的出现,具身对话代理已成为在线交互的代名词。这些代理拥有大量知识,但表现出有限的情感表达性。缺乏充分的表达,代理可能无法适应用户的情绪,这可能导致用户体验和参与度不理想。目前大多数系统优先考虑基于内容的响应,忽视对话中的情绪上下文。该领域的研究目前局限于特定情境,如心理健康。为了弥合这一差距,我们的项目提出了在虚拟对话代理中实现表达性特征,该代理将利用情感分析和自然语言处理来指导生成富有同理心和表达性的响应。项目交付了一个能够评估和响应用户情绪的实用对话代理。我们认为这将提高可用性、参与度以及对话的整体质量,并展示了从探索性试点研究中得出的结果。

英文摘要:

With the advent of generative AI and large language models, embodied conversational agents are becoming synonymous with online interactions. These agents possess vast amounts of knowledge but suffer from exhibiting limited emotional expressiveness. Without adequate expressions, agents might fail to adapt to users' emotions, which may result in a sub-optimal user experience and engagement. Most current systems prioritize content based responses, neglecting the emotional context of conversations. Research in this space is currently limited to specific contexts, like mental health. To bridge this gap, our project proposes the implementation of expressive features in a virtual conversational agent which will utilize sentiment analysis and natural language processing to inform the generation of empathetic, expressive responses. The project delivers a functional conversational agent capable of assessing and responding to user emotions accordingly. We posit this will enhance usability, engagement, and the overall quality of conversations and present results from an exploratory pilot study investigating the same.
