A legal tech firm is developing an LLM to summarize lengthy court case documents for lawyers. Their training strategy involves two feedback loops: 1) An AI system automatically scores the summaries based on whether they are 'easy to read' and have a 'professional tone'. 2) A team of paralegals manually verifies that all names, dates, and specific legal citations mentioned in the summary are factually correct. Critically evaluate this hybrid feedback strategy. In your evaluation, identify the primary weakness of this approach and propose a more effective way to combine AI and human feedback for this specific task, justifying your proposal based on the distinct strengths of each feedback type.
