あなたの研究テーマについて教えてください。What is your research theme?
My research focuses on developing a chatbot that understands and generates “salty language” using large language models (LLMs), while ensuring adherence to ethical standards. “Salty language” refers to informal, humorous, or emotionally expressive speech that may include profanity but is not inherently offensive. This type of language plays a significant role in emotional communication and everyday interactions, yet current LLMs often avoid it due to concerns about ethical and security compliance.
The research involves constructing a specialized dataset to distinguish salty language from genuinely offensive expressions, fine-tuning LLMs through instruction training to generate context-appropriate salty language, and refining the model based on manual evaluation and user feedback.
The academic significance of this work lies in its exploration of the “gray areas” of language that challenge conventional boundaries of toxicity detection. It offers valuable insights into the subtleties of human communication and how LLMs can be adapted to better reflect these complexities.
The potential societal impact includes creating more authentic and emotionally engaging AI interactions, especially in fields like language therapy and education. By addressing ethical and cultural considerations, this research aims to build trust in AI and promote its use in sensitive, human-centric applications.
なぜ博士課程へ進学しましたか？Why did you decide to pursue a doctoral program?
I decided to pursue a doctoral program because of my desire to explore the complexities of natural language processing (NLP) beyond what I achieved during my master’s studies. While working on offensive language detection, I encountered a significant gap: distinguishing offensive language from non-offensive expressions of profanity, such as emotionally charged but harmless language. This challenge intrigued me and revealed the limitations of current NLP systems in capturing the subtleties of human communication.
A master’s program provided a strong foundation, but I felt it did not allow for the depth of exploration or innovation I wanted to achieve. I was particularly drawn to interdisciplinary approaches that integrate insights from sociology and psychology into NLP, and I realized that pursuing a doctoral program would enable me to engage in advanced, original research in this area. My ultimate goal is to create AI technologies that better understand and reflect human emotions and cultural contexts, and a doctoral program offers the time, mentorship, and resources to make meaningful contributions to both academia and society.
