During the article a hybrid named-entity recognition (NER) algorithm for Uzbek is presented. It combines rule-based modules (transliteration, dialect normalization, morphological analysis) with modern neural network models. The study is motivated by Uzbek’s agglutinative morphology, dialect diversity and the lack of specialized resources, which hinder the direct application of named entity recognition methods developed for English or other high-resource languages. As part of the work, an annotated corpus of more than three thousand sentences in the Uzbek language was formed, including legal documents, scientific articles, news materials and informal texts from social networks. The corpus is marked up according to the BIOES scheme taking into account the specific morphological and lexical features of the Uzbek language. The developed rule-oriented algorithms (transliteration, dialect standardization, morphological analysis) are integrated into a single post-processing system that complements neural network models. As a result of experiments aimed at assessing the effectiveness of the proposed approach, it was found that the hybrid approach significantly improves the accuracy and completeness metrics of named entity recognition in different thematic domains. The practical value of the study is that the proposed system can serve as a basis for automatic processing of Uzbek texts in the tasks of searching and extracting information, dialect normalization, annotating large text data and digitalization of document flow. The theoretical significance is that the work expands approaches to named entity recognition for low-resource languages, offering methods that take into account morphological-syntactic and dialectal features.
This article discusses the issues of improving the methodology and technology for the off-season storage of grain harvesting combines. The main factors affecting the preservation of the technical condition of combines, including storage conditions, quality of maintenance, and the qualification of the operator, are analyzed. Based on the research, the causes influencing the reduction of the service life of combine units were identified, and patterns enabling their quantitative evaluation were developed. In addition, recommendations are provided to improve the reliability and service life of combines through the optimization of maintenance and storage processes.
This research paper is devoted to the modernization of solar and wind power plants in Uzbekistan. The use of renewable energy sources in the country has been developing rapidly in recent years, and this process is becoming increasingly important in ensuring energy security and strengthening environmental sustainability. Introduction: Energy Landscape and Renewable Role.
The purpose of this work is to evaluate the stress-strain state of cotton threads with a linear density of 29 tex on a sizing machine SHB – 11/140 along the threading width of the sizing machine. The relevance of this work is that the study of the stress-strain state of cotton yarn will allow us to quickly influence the course of the technological process, as a result of which breakage will be reduced and productivity will increase both in sizing and in subsequent processes. Therefore, the primary goals of sizing are to improve the yarn's resistance to friction and high-cycle loads during its passage through the loom, as well as to create the yarn package necessary for the weaving process.
Maqolada Navbahor koni bentonit gilini xlorid kislota yordamida kislotali modifikatsiyalash jarayoni hamda uning fizik-kimyoviy xossalariga taʼsiri tadqiq etilgan. Bentonit namunalari 0,1 M va 1,5 M HCl eritmalari bilan faollashtirilib, ularning kimyoviy tarkibi hamda sirt morfologiyasidagi oʻzgarishlar skanerlovchi elektron mikroskop (SEM) yordamida baholangan. Tadqiqot natijalari kislotali ishlov berish natijasida almashinuvchi kalsiy, natriy va magniy ionlari miqdori sezilarli darajada kamayishini, montmorillonitning asosiy kristall tuzilishi esa saqlanib qolishini koʻrsatdi. Shuningdek, bentonit yuzasida yangi gʻovaklar hosil boʻlishi va sorbsion faollikning ortishi aniqlandi. Olingan natijalar modifikatsiyalangan bentonitlarni adsorbent va sorbent material sifatida qoʻllash istiqbollari yuqori ekanligini tasdiqlaydi.
