Abstract (English): The dissertation by Kemelbekova Elmira Abdenovna on the topic «Semantic modification of applied geometry terms» has been prepared for the award of the degree of Doctor of Philosophy (PhD) in the educational program «8D02305 – Phylology» ABSTRACT General characteristics of the study. The rapid development of modern science and technology, including the expansion of engineering graphics, architecture, computer modeling, design, and digital technologies, has a direct impact on the continuous development and renewal of the terminology of applied geometry. In this process, geometric terms are used in new scientific contexts, resulting in changes in their semantic structure, that is, semantic modifications arise. The terms of applied geometry encompass not only mathematical concepts but also complex notions related to technical, engineering, and information fields. As a result, the same term may be used in different domains with different meanings, undergoing such semantic processes as polysemy, metaphorization, terminologization, and determinologization. Such processes may lead to inconsistencies in terminological standardization and difficulties in understanding scientific texts. In this regard, identifying the semantic modifications of applied geometry terms, the patterns of their semantic development, and the mechanisms of their transformation constitutes a relevant issue in terminology studies and cognitive linguistics. Relevance of the dissertation research. The terminological fund of applied geometry in the Kazakh language has been formed and consolidated to a certain extent in official sources: a significant number of terms have been approved by the State Terminological Commission under the Government of the Republic of Kazakhstan and are presented in the terminological database (http://termincom.kz). However, the terms of applied geometry in the Kazakh language have not yet been sufficiently examined in the context of interdisciplinary relations, and comprehensive studies in this field have hardly been conducted. In the context of the modern global «Fourth Industrial Revolution», when Kazakhstan’s engineering potential is actively developing and integrating into the international scientific and technological space, there arises a need for the study, systematization, and linguistic analysis of the terminological fund of applied geometry in the Kazakh language in accordance with new scientific and technological requirements. In this regard, the system of applied geometry terms and the processes of their semantic modification represent one of the pressing scientific issues of modern linguistics. Semantic transformation of geometric concepts and terms contributes to the expansion of their polysemy and functional-semantic range of usage. This process enhances the potential of the Kazakh language as a language of science and necessitates the development of semantic models reflecting the peculiarities of national cognitive and cultural perception. The relevance of the study is also determined by the objectives of the state language policy. The State Program for the Implementation of Language Policy in the Republic of Kazakhstan for 2020–2025 (Resolution of the Government of the Republic of Kazakhstan No. 1045 dated December 31, 2019) defines tasks aimed at improving the national terminological fund. In addition, the Law of the Republic of Kazakhstan “On Education” (No. 319-III dated July 27, 2007), as well as the speech of the President of the Republic of Kazakhstan, K. Tokayev, at the ceremonial session dedicated to the 75th anniversary of the Academy of Sciences, emphasize the need to improve scientific research and introduce innovative approaches into scientific activity. In accordance with these regulatory documents, the importance of issues related to the formation, systematization, and standardization of the national terminological fund is increasing. The semantic modification of applied geometry terms, which constitutes the core of the present dissertation, represents a new scientific direction and is considered for the first time in Kazakh linguistics as an independent object of research. At present, difficulties arise in the educational process when explaining certain terms of applied geometry. Moreover, specialists often demonstrate differing interpretations of some terms. In this regard, compiling a Kazakh–Russian–English dictionary of applied geometry terms used in higher education becomes an urgent task. Object of the research. Terms of applied geometry in the Kazakh language. Subject of the research. Features of the semantic modification of applied geometry terms. The aim of the research. The aim of the study is the theoretical and practical investigation of the features of semantic modification of applied geometry terms in the Kazakh language. To achieve this goal, the following objectives are set: 1. To theoretically systematize the history of the formation and study of applied geometry terms, and to determine their place in Kazakh terminology and the main stages of their development. 2. To analyze the lexical-semantic features of applied geometry terms in the Kazakh language from the perspectives of motivation and onomasiology. 3. To identify the types of semantic changes in applied geometry terms (semantic narrowing, semantic broadening, semantic derivation, metaphorical and metonymic transfers) and describe the mechanisms of their implementation. 4. To develop and scientifically substantiate a semantic model of the transition from general lexical meaning to terminological meaning. 5. To classify the modification structures of applied geometry terms and determine their analytical and structural features. 6. To model the conceptual structure of applied geometry terms on the basis of frame analysis and identify the system of their cognitive organization. 7. To conduct quantitative and qualitative analyses of the semantic modification of applied geometry terms and substantiate the obtained results with statistical data. 8. To determine the ethnolinguistic and cognitive features of applied geometry terms and substantiate their connection with the national spatial worldview. 9. To develop a Kazakh–Russian–English dictionary of applied geometry terms and systematize the historical-semantic development of the terms. Scientific novelty of the research. The scientific novelty of the dissertation is determined by the following specific results: 1. For the first time in Kazakh linguistics, the semantic modification of applied geometry terms has been comprehensively examined as an independent object of research. Based on a 30-volume terminological dictionary, the structural, semantic, and conceptual features of more than 3,000 terms were systematized through quantitative and qualitative analyses. 2. For the first time, the leading role of semantic derivation in the formation of applied geometry terms was proven on the basis of statistical and linguistic data, and the functions of semantic narrowing and semantic broadening in the process of terminologization were systematically described. 3. A model of the transition from general lexical meaning to terminological meaning was proposed: «general meaning → semantic selection → specification of meaning → terminological meaning». The structural-semantic mechanism of terminologization was theoretically substantiated. 4. The metaphorical nomination of applied geometry terms in the Kazakh language was, for the first time, examined as an independent object of research. Anthropomorphic, artifact-based, natural, and sociomorphic metaphorical models were identified. Models of metonymic transformation based on the patterns «action–result», «whole–part», and «property–abstraction» were systematized. 5. The conceptual structure of applied geometry terms was modeled on the basis of cognitive frame analysis. As a result of the quantitative classification of 200 terminological units, the proportional distribution of frames was determined, and the hierarchical organization of the terminological system was statistically proven. 6. The morphological structure of applied geometry terms was analyzed for the first time on the basis of an extensive corpus of data. Productive and non-productive affixes were systematized using materials from more than 3,000 terms; rarely used suffixes were identified, and the derivational hierarchy of term formation was established. 7. Based on the materials of the 30-volume dictionary, the process of borrowing terms was analyzed, and their frequency indicators and dynamics of distribution across different historical periods were determined through quantitative analysis. 8. As a result of a retrospective content analysis conducted using the Google Books Ngram Viewer platform, the frequency of use of applied geometry terms and the dynamics of their semantic development were, for the first time, systematized graphically and statistically. 9. The historical stages of the development of applied geometry terms were evaluated using SWOT analysis, which made it possible to identify the strengths and weaknesses of the terminological system, as well as determine its development prospects and potential risk factors. 10. A Kazakh–Russian–English dictionary of applied geometry terms was developed, systematizing the historical-genetic and semantic evolution of the terms. 11. Applied geometry terms were, for the first time, studied from the perspectives of cognitive linguistics and terminological linguoconceptology. The theoretical principles of cognitive terminology studies were identified, and the concepts of the scientific worldview and professional linguistic personality were formulated on the basis of applied geometry terminology. 12. In the process of translating applied geometry terms, regularities in rendering into Kazakh the terms formed with the suffixes -ный, -ная, and -ное were established. On the basis of the principles of functionality and linguistic economy, a scientifically grounded model for term unification was proposed. The theoretical and methodological framework of the research was formed by the scientific concepts of domestic and foreign scholars in the fields of general terminology, cognitive linguistics, and ethnolinguistics. Among Kazakhstani scholars, the works of A. Baitursynuly, K. Zhubanov, M. Dulatuly, E. Omaruly, S. Kozhanuly, N. Karatyshkanov, K. Zhalenuly, K. Satpayev, Sh. Bilal, Akzhan al-Mashani, U. Aitbaiuly, Sh. Kurmanbaiuly, S. Amanzholov, S. Kulmanov, S. Aliszhan, S. T. Akayev, E. Orazaliyeva, S. S. Isakova, G. A. Begimova, and others were used. The theoretical principles of foreign scholars are represented in the works of O. Wüster, J. C. Sager, Alain Rey, M. T. Cabré Castellví, G. Rondeau, Eugenio R. Luján, G. Lakoff, Ch. Fillmore, M. Foucault, M. Black, S. V. Grinev-Grinevich, I. V. Pashkova, V. M. Toporova, I. O. Kraevskaya, and others. The study also employed philosophical principles and the fundamental concepts of the theory of scientific cognition. The analysis of the semantic modification of applied geometry terms requires a systematic description of changes in the meanings of linguistic units depending on historical period, scientific paradigm, and sphere of functioning. Research methods and techniques. To accomplish the objectives of the study, a set of general scientific and specialized linguistic methods was employed. In particular, the methods of content analysis, comparative-historical, contrastive, semasiological, onomasiological, cognitive, and ethnolinguistic analysis were applied. In order to model the conceptual structure of terms, frame analysis was conducted, and its results were visualized using the mind map method. In addition, SWOT analysis, quantitative analysis, comparative-etymological analysis, and retrospective content analysis based on the Google Books Ngram Viewer platform were used to determine the dynamics of term development, the frequency of their usage, structural features, and to evaluate the strengths and weaknesses of the development of the terminological system. Theoretical significance of the research. The theoretical significance of the study lies in the fact that its results contribute to solving a number of theoretical issues related to the terminology of applied geometry. In particular, the processes of semantic modification of terms, semantic narrowing and broadening, semantic derivation, metaphorical and metonymic models, frame organization, and morphological structure of terms have been systematized, while the semasiological and cognitive mechanisms of the process of terminologization have been clarified. The obtained results provide a scientific basis for the further development of terminology studies, semasiology, word-formation theory, and cognitive terminology. Practical significance of the research. The practical significance of the research results lies in the possibility of their application in the development of educational and methodological materials on applied geometry, engineering graphics, and technical disciplines; in ensuring the uniformity of terms; in compiling specialized terminological dictionaries and multilingual (Kazakh–Russian–English) explanatory dictionaries; in creating a domain-specific thesaurus reflecting the structural and semantic relations of applied geometry terms; as well as in the standardization and codification of terms in scientific and technical texts. In addition, the results of the study may be applied in implementing the principle of «one term – one concept» in the process of term formation. Furthermore, the results of the research may be used in the digitalization and automation of applied geometry terminology. In particular, they can serve as a basis for developing electronic terminological databases; creating intelligent terminological systems based on frame models; designing systems for automated morphological and semantic analysis of terms; ensuring consistent translation of domain-specific terms in machine translation systems; improving AI-based algorithms for terminological identification and retrieval; as well as developing an electronic thesaurus and a digital terminological platform for applied geometry. Thus, the results of the study are significant not only from a theoretical perspective, but also in the fields of education, terminological standardization, lexicography, and the development of digital terminology. Main provisions submitted for defense: 1. Applied geometry terms represent not only a system of names denoting technical concepts, but also a linguistic reflection of national worldview and spatial thinking. The terminological system represents a national-cognitive model of the scientific worldview. 2. Semantic derivation plays a leading role in the formation of applied geometry terms. The processes of semantic narrowing and semantic broadening function as the main semasiological mechanisms of terminologization. 3. The process of terminologization is carried out according to the model «general meaning → semantic selection → specification of meaning → terminological meaning», through which the закономерность of the linguistic formation of a scientific concept is determined. 4. The semantic modification of applied geometry terms is realized through cognitive models (frame, metaphor, metonymy). Anthropomorphic, artifact-based, natural, and sociomorphic metaphorical models, as well as metonymic models such as “action–result,” “whole–part,” and “property–abstraction,” determine the conceptual organization of the terminological system. 5. Borrowed terms in the field of applied geometry in the Kazakh language undergo processes of linguistic and cultural adaptation, become integrated into the national conceptual system, and acquire new semantic nuances. 6. Adherence to the principle of “one term – one concept” in the translation and formation of terms is a scientifically grounded mechanism for ensuring the consistency and standardization of specialized terminology. 7. The ethnolinguistic nature of applied geometry terms is closely connected with the national worldview and reflects the linguistic representation of the scientific worldview. Approbation of the research results. The research results have been disseminated through 20 publications on the topic of the dissertation, including 6 articles in journals included in the list recommended by the Committee for Quality Assurance in Science and Higher Education of the Ministry of Science and Higher Education of the Republic of Kazakhstan, 12 articles in the proceedings of domestic and international scientific-theoretical and scientific-practical conferences (including 1 article published in a journal indexed in the Scopus citation database), 1 chapter in a collective monograph, and 1 published terminological dictionary.
