Abstract Various international organizations and classification societies have established extensive regulations to enhance the safety and reliability of ships. These regulations are continuously revised and updated to keep pace with technological advancements, the increasing size of ships, and the tightening of environmental regulations in the shipbuilding and maritime industry. However, the complex formats, including formulas and tables, and the high level of expertise required to comprehend these regulations pose significant challenges for users seeking to retrieve and accurately interpret the necessary information quickly.
This study proposed a generative AI-based search method for ship regulations utilizing Retrieval-Augmented Generation (RAG) to address these challenges. The proposed method comprises a Question-and-Answer (Q&A) system that retrieves relevant information from a large-scale database and generates reliable answers tailored to the intent of the user’s query. To achieve this, we built ship regulations into a database optimized for searchability and incorporated hierarchical structures to improve search accuracy. Additionally, a domain adaptation technique was applied to a general-purpose language model, enabling the Q&A system to clearly understand the specialized terminology and context within the domain of ship regulations.
The Q&A system developed in this study supports users in quickly navigating ship regulations, facilitating clear comprehension and practical application of the information. The proposed method was applied to the “Classification Technical Rules” regulations of the Korean Register, demonstrating its capability to promptly and accurately retrieve rules related to user queries within the regulations and generate reliable answers.
