Researchers have developed SemViews, a novel semantic query engine designed to optimize the use of large language model (LLM) labels. This system reuses previously collected labels as "semantic views" to reduce the cost of evaluating natural-language filters. SemViews prioritizes tuples based on these existing labels, local embeddings, and a helper model's score before refining the order with new oracle calls, ensuring user-defined precision and recall targets are met with high probability. In experiments, SemViews achieved significant savings in oracle calls compared to prior methods, particularly when queries were rephrased. AI
IMPACT Optimizes LLM inference costs by enabling efficient reuse of labels, potentially reducing operational expenses for AI applications.
