What problem does the paper attempt to solve? Is this a new problem?

The paper aims to address the challenge of achieving stable persona consistency in role-playing agents by proposing a novel persona reconstruction framework called CharacterGPT . This framework involves Character Persona Training (CPT), which updates the character persona by extracting traits from the summary of the novel for each chapter as the story progresses . The problem of maintaining consistent persona in role-playing agents is not new, but the paper introduces a new approach to alleviate the shortcomings of existing methods and enhance persona stability .


What scientific hypothesis does this paper seek to validate?

This paper aims to validate the scientific hypothesis related to enhancing consistency and role-specific knowledge capturing by rebuilding fictional character's persona. The hypothesis revolves around the effectiveness of a novel persona-based assistant, CharacterGPT, in preserving persona and knowledge through a structured character traits approach . The research focuses on addressing the challenge of achieving stable persona consistency by proposing a persona reconstruction framework that updates character persona traits based on the progression of a story in a novel . The study explores the impact of this approach on maintaining persona consistency, especially in role-playing agents, by amalgamating extracted trait information into the character persona document in chronological order .


What new ideas, methods, or models does the paper propose? What are the characteristics and advantages compared to previous methods?

The paper "Enhancing Consistency and Role-Specific Knowledge Capturing by Rebuilding Fictional Character's Persona" proposes a novel framework called CharacterGPT that focuses on persona-based assistants . This framework involves a process called Character Persona Training (CPT), where the character persona is updated by extracting traits from a given summary of a novel for each chapter, simulating the progression of a story . The method aims to address the challenge of achieving stable persona consistency by rebuilding the character's persona effectively .

CharacterGPT introduces a structured approach to character traits input, emphasizing the importance of maintaining consistent persona and knowledge . It leverages a persona rebuilding framework that amalgamates extracted trait information into the same paragraph within a character persona document in chronological order . This approach ensures that each trained protagonist's persona is stored every epoch, offering advantages for various domains, especially in non-player characters (NPC) in games .

Furthermore, the paper discusses the convergence of psychology and technology in the field of Natural Language Processing (NLP) . It highlights the application of foundational personality theories like the Big Five Inventory (BFI) and the Myers-Briggs Type Indicator (MBTI) in developing psychometric tools for assessing individual differences across domains . This integration of psychology concepts with technology has led to the emergence of Large Language Models (LLMs) like CharacterGPT, expanding the potential for personality assessment and personalized interactions . The proposed framework, CharacterGPT, introduces a structured approach to character traits input, emphasizing the importance of maintaining consistent persona and knowledge . This framework consists of an initialization phase where the story's progress-related content is removed, and a training phase where the character persona is updated by extracting traits from a given summary, simulating the progression of a story in a novel . By following this process, CharacterGPT effectively preserves persona and knowledge, addressing the challenge of achieving stable persona consistency .

One key advantage of CharacterGPT is its ability to minimize information loss and computational cost that occurs in document-based retrieval . By rebuilding the character persona document according to traits in chronological order, this framework alleviates the problem of unstable search locations within the document when using the Assistants API . Additionally, CharacterGPT generates a total of 16 character personas chronologically based on the novel's summary, allowing users to interact with characters at specific points in the story, enhancing the user experience .

Furthermore, CharacterGPT demonstrates superior performance in maintaining a character's persona compared to models that do not utilize this framework . The ablation study shows that characters without CharacterGPT fail to effectively capture the persona of the character, highlighting the importance of this framework in maintaining persona consistency . Additionally, the framework enables characters to evolve and change throughout the story, enhancing role-specific knowledge capturing and controllability .

In conclusion, CharacterGPT offers significant advantages over previous methods by effectively preserving persona and knowledge, minimizing information loss and computational costs, enabling interactions at specific story points, and enhancing role-specific knowledge capturing and controllability .
