Imagine having instant access to legal counsel, anytime, anywhere. That's the promise of DeliLaw, a new AI-powered legal counseling system developed in China. Traditional legal research can be a daunting task, sifting through countless documents and precedents. DeliLaw simplifies this process by using a large language model (LLM) to understand your legal questions and provide relevant information in a conversational manner, much like chatting with a human expert. But how does it work, and how effective is it? DeliLaw goes beyond simple keyword searches. It leverages advanced natural language processing to grasp the nuances of your queries, providing more accurate and helpful responses. To combat the common LLM issue of "hallucination," or generating false information, DeliLaw incorporates a two-pronged retrieval system. First, it pulls from a continuously updated legal database to ensure accuracy. Second, it has an efficient case retrieval module using a two-step process: keyword extraction followed by retrieval from a massive database of cases, ensuring access to relevant precedents. Think of it as having a legal library at your fingertips. But building a system like this isn't without its challenges. The sheer volume of legal texts requires sophisticated fine-tuning of the LLM. DeliLaw’s developers tackled this by training the model on a combination of general Chinese text and specialized legal data, including Q&A data, real-world case studies, and even simulated conversations between lawyers and clients. The development of DeliLaw has already shown positive results. In comparison with other leading LLMs, including ChatGPT, DeliLaw demonstrated a superior ability to provide accurate legal advice, correctly citing relevant laws and regulations. This isn’t just theoretical; DeliLaw is already in use, boasting over 20,000 professional users and handling nearly 3,000 queries daily. The accessibility of this technology has the potential to change the way people interact with the legal system, making legal information more readily available. While DeliLaw is currently focused on Chinese law, the underlying technology could be adapted for other legal systems, opening up a future where seeking legal guidance becomes as simple as asking a question.
