Diversity-Aware Top-k Publish/Subscribe for Text Stream

Summary: Diversity-Aware Top-k Subscription (DAS) maintains k up-to-date documents per query, balancing relevance, recency, and diversity in a text-stream. Scalable DAS processing for many queries yields 60–75% speedups over baselines on real data, with validated diversity benefits. (summarized by gpt-5-nano on Feb 09 2026)
