Publication number: 20260277933Abstract: A topical cluster hierarchy (TCH) is constructed by recursive subclustering of document clusters until a termination condition is detected. The clusters have centroids of topic proximity with respect to at least one user-specified topic. Subclustering starts after thresholds of minimal cluster topic proximity or minimal cluster coherence are met, thus avoiding processing of low-utility clusters. Subclustering terminates when sufficient topic proximity, coherence, or cluster depth is reached. A tool utilizes the TCH to control topic-directed searching, topic-directed filtering, analyzing, summarizing, or categorizing, of documents.Type: ApplicationFiled: April 29, 2025Publication date: September 17, 2026Inventors: Ge WANG, Pak On CHAN, Deepika PURI, Andy NGUYEN, Vinayak NADIR, Ghazal MAZAHERI, Milenko DRINIC, Samuel Johnson SHELTON, Sundar KAMESWARAN, Nicholas James ROBINSON, Ramya KONERU, Annapurna Lakshmi SARIPALLI, Chen XU, Kai LIANG, Israa Qasim JARADAT, Pankaj Jitendra PARIKH, Michael RAWSON, Maxim NACU, Venkata Rao SALADI
