用家庭照片对话帮助老人锻炼思维、缓解孤独，还能让照顾者了解其情绪状态。
A Goal-Oriented Chatbot for Engaging the Elderly Through Family Photo Conversations
- 基于家庭照片生成提问，引导老人自然对话并刺激认知功能。
- 通过分析对话内容识别偏好，动态推荐相关照片继续交流。
- 为照护者提供上传照片和查看聊天记录的网页平台，便于远程关怀。
我们提出一种面向老年人的个性化聊天机器人，以家庭照片为切入点，引导用户自然展开对话。对话过程中，机器人会生成关于‘谁、哪里、何时、什么’的问题来激发认知活动，并随后提出开放式问题促进积极回忆。该系统采用目标导向的对话框架，每次对话后分析用户兴趣点，可自动推荐包含相同家庭成员或前文提及人物的其他照片。为此，我们还开发了一个网页门户，供照护者上传照片并查阅聊天记录。该聊天机器人不仅能提升老人的参与度、减轻孤独感，也为照护者提供了了解老人心理状态的重要工具。
原文摘要 · Abstract (English)
We propose a personalized chatbot designed for elderly individuals. The chatbot initiates discussions based on family photos, encouraging users to interact naturally. During these interactions, it generates W questions (who, where, when, and what) to stimulate cognitive function, followed by an open-ended question to promote positive reminiscence. This approach is structured around a goal-oriented dialogue framework. Additionally, after each conversation about a photo, the chatbot analyzes the discussion to identify topics that the user favors or dislikes. It then offers the user the option to chat about another photo either featuring the same family members or an individual previously mentioned in the conversation. To support this system, we have developed a web portal that allows caregivers to upload photos and review chat conversations. This personalized chatbot not only encourages elderly users to engage with the chatbot regularly and reduces feelings of loneliness but also provides caregivers with a valuable tool to gain insights into users' well-being.
