Chat Summarization

Chat summarization is an NLP technique that extracts important information and key points from chat or conversational text and condenses them into a concise summary. It is used to efficiently grasp and share the content of large volumes of conversation logs or online chat, and is attracting attention across business, customer support, education, and many other fields. There are two main types of chat summarization: • Extractive summarization: Pulls out important sentences or phrases from the conversation directly • Abstractive summarization: Understands the original text and generates a summary in new language. This approach allows for contextual understanding and paraphrasing. In recent years, abstractive chat summarization using large language models (LLMs) such as GPT-based systems has achieved high accuracy, evolving from simple transcription into meaningful extraction of key points. Use cases include summarizing customer support chat histories, producing minutes for meetings and discussions, and organizing information from SNS and forums. Chat summarization is an important technology that reduces information overload from large volumes of conversational data and supports efficient communication and decision-making.
