Cover Story: AI is revolutionizing the legal field, enhancing efficiency and fairness in critical tasks like finding similar cases—a cornerstone of legal practice. Our research introduces a groundbreaking semantic search system that identifies comparable legal decisions using concise fact drafts. By analyzing over 1100 Hungarian court decisions, we compared 12 cutting-edge text-embedding models and implemented innovative techniques like last-chunk scaling. Models such as Cohere and BGE-M3 excelled in handling lengthy, complex texts. Validated by legal experts, our system promises to transform legal case retrieval, saving time while improving accuracy. View this paper
