用低代码平台连接聊天机器人与后端服务，实现前后端无缝集成。
Low-code from frontend to backend: Connecting conversational user interfaces to backend services via a low-code IoT platform
- 通过Rasa与Node-RED搭建中间件架构，实现前端对话与后端服务的低代码对接。
- 无需手动编码即可完成聊天机器人与业务系统的联动，支持事务型交互。
- 适合无编程背景的开发者快速构建智能客服或物联网应用。
当前聊天机器人开发平台主要支持语言与对话逻辑的构建，但连接后端服务和业务功能仍需大量手动编码与编程技能。本文提出一种新方法：以聊天机器人作为前端，采用开源物联网平台Node-RED作为中间件，实现前后端连接。具体地，论文详细阐述并演示了如何将基于开源平台Rasa开发的聊天机器人与Node-RED结合，从而在无需编写代码的情况下，从前端到后端实现事务型对话界面的低代码/无代码开发。
原文摘要 · Abstract (English)
Current chatbot development platforms and frameworks facilitate setting up the language and dialog part of chatbots, while connecting it to backend services and business functions requires substantial manual coding effort and programming skills. This paper proposes an approach to overcome this situation. It proposes an architecture with a chatbot as frontend using an IoT (Internet of Things) platform as a middleware for connections to backend services. Specifically, it elaborates and demonstrates how to combine a chatbot developed on the open source development platform Rasa with the open source platform Node-RED, allowing low-code or no-code development of a transactional conversational user interface from frontend to backend.
