A New Era of Conversational AI - Persona Chatbots
Getting started
A persona chatbot is an interactive AI system designed based on a specific person, personality, or role. Beyond traditional simple question and answer chatbots, we aim for emotional connection and immersion that users can feel. For example, we provide more humane communication with users by setting up roles such as psychological counselors, game characters, and brand spokespersons.
The history and development of persona chatbots
- ELIZA (1966): The Beginning of Persona Chatbots
ELIZA simulated the “psychological counselor” persona for the first time and showed the possibilities of interactive AI.
- features: Generate keyword-based responses.
- Limitations: The rules-based system does not have a deep understanding of the meaning of the conversation.
- Strengthen large-scale language models and personas
The development of modern persona chatbots is based on large-scale language models (LLM) such as GPT and BERT. They support sophisticated persona design through contextual understanding, sentiment analysis, and adaptive conversation.
The technical components of a persona chatbot
- Natural Language Processing (NLP) and Large Language Models (LLM)
- Models such as GPT and T5 understand the context and generate appropriate responses.

- Persona design
- Explicit personas: A character set via a specific conversation dataset.
- Implicit personas: Character traits that come naturally during conversation.
- Reinforcement learning (RLHF)Technology that continuously improves personas based on user feedback.
