Using taxonomy, discriminants, and signatures for navigating in text databases

Summary: Organizes text-search results within a corpus taxonomy, augmenting each node with dynamically computed, context-sensitive document signatures. A lightweight multilevel classifier isolates node-specific discriminants from noise, enabling fast, accurate navigation and updates. (summarized by gpt-5.6-luna on Jul 24 2026)
