From Generalist to Specialist: Customizing LLMs for Building Laws in Norway

At Norkart, we have spent the last year developing an LLM-based system to extract specific information from complex property regulations and laws, helping architects and property owners answer the question: What can you build on this property? Initially, with a basic RAG-system, the performance was rather fluctuating and inconsistent - as we often see with LLMs. We then had two options: Abandon the idea or dig deeper into the mud. We chose the latter! To create a system we can truly rely on to understand and simplify these intricate regulations, we developed a series of customizations, including: - Preprocessing - how we analyze and chunk our documents in order to keep the semantic meaning of each part of the text. - Teaching the system Domain-Specific Terms and Expressions. - Efficiently benchmark the performance of the customized RAG-system. - Combining UI and AI to simplify the system Join us to find out how we wrestled with the chaos of Norwegian building laws, tamed it with AI, and finally taught our system to answer the age-old question: "Can I build a jacuzzi here?"
