  • Methods and Algorithms of POS-tagging of Adverbs and Pronouns in Uzbek Texts

    In this scientific article, the problem of automatic identification of adverbs and pronouns in Uzbek texts is analyzed based on linguistic and computational approaches. For the Uzbek language, which has an agglutinative structure, the task of POS-tagging causes not only morphological, but also syntactic difficulties. In particular, the multifunctional and contextual variability of adverbs and pronouns requires precise approaches to their automatic classification. The article analyzes performance indicators between traditional rule-based algorithms, as well as modern models based on statistical and neural networks (Conditional Random Fields and BiLSTM). Methodologically, the formal classification of models, their functionality and experimental foundations. Based on the results, the advantages and weaknesses of each approach are identified, and proposals for the optimal tagging model for the Uzbek language are put forward. The research results will be of great importance for morphological analysis, machine translation, automatic text indexation, and improving the overall quality of Uzbek NLP systems.

    This paper presents a comprehensive study of two statistical approaches to part-of-speech (POS) tagging in Uzbek - the Hidden Markov Model (HMM) and the Conditional Random Field (CRF) - from both mathematical and empirical perspectives. We first formalize each model: transition and emission probabilities for HMM, and feature functions with weight parameters for CRF. Both models were trained on a 205 k-token (77821 sentences) CONLL-U corpus annotated with 15 Uzbek-specific POS tags, employing Laplace-smoothed Viterbi decoding for HMM and an L-BFGS-optimized CRF with Viterbi inference. On the held-out test set, the HMM achieved 82% tagging accuracy, while the CRF reached 88%, outperforming HMM by six percentage points thanks to its richer contextual and linguistic features. The results confirm that statistical models remain robust for agglutinative, low-resource languages like Uzbek, yet are sensitive to feature engineering. We conclude with an error analysis, guidelines for model selection, and perspectives on migrating to neural architectures such as BiLSTM-CRF and BERT-based taggers.

    The development of a semantic analyzer of natural language is considered one of the factors that develop the language. Homonymy is one of the main elements of semantic analysis. Different methods can be used for semantic analysis of homonyms. Homonyms can also be determined using Lesk's algorithm. Lesk's algorithm is based on WordNet of natural language. The weight of the compounds of the homonymous word in the sentence entered through WordNet is determined. The meaning of the word homonym was determined according to the compounds with high weight.
  • The Problem of Pos Tagging and Stemming for Agglutinative Languages (Turkish, Uyghur, Uzbek Languages)

    The number of possible word forms in agglutinative languages is theoretically unlimited. This, in turn, creates the problem of POS tagging (part-of-speech) of out-of-vocabulary (OOV) words in agglutinative languages. In agglutinative languages, words are formed by adding suffixes to the stem. Due to the occurrence of phonetic harmony and disharmony while adding suffixes to the stem, it is necessary to analyze both phonetic and morphological changes. When solving many NLP tasks, it is necessary to reduce word forms to the stem (stemming). Removing all inflectional affixes from a word and lemmatizing the rest of the word is considered one of the important tasks of natural language processing (NLP), and this process is called stemming. The stemming process is important in information retrieval (IR) systems.
