AN INTELLIGENT INFORMATION SYSTEM FOR UZBEK TEXT PROCESSING AND GRAMMATICAL QUESTION-ANSWERING

“UZAI Tahlil” integrates morphological, syntactic and lexical-statistical processing of Uzbek texts with source-grounded grammatical question answering. The system combines UzbekTaggerBERT, ByT5, Viterbi morphotactic validation, mDeBERTa-v3 + CRF, and hybrid BM25/MPNet retrieval-augmented generation. Experiments achieved F1 = 96.8% for morphotactics, macro F1 = 91.4% for syntactic classification, and Hit@4 = 97.1% for grammar retrieval.
