Popis: Context. Nowadays there is a constantly increasing interest to the application of the intelligent systems (IS) in different areassuch as information technologies (IT), engineering, medicine, biology, ecology, geography, jurisprudence etc. At the heart ofarchitecture of modern IS’s knowledge bases (KB) are used, which are formed due to the subject area (SA), where the given IS isused. The main part of KB is ontology as clearly structured SA’s model, systematic set of terms, which explain the connectionsbetween objects of this SA. Ontologies are generally accepted and widely used in different branches of science such as knowledgeengineering, presentation of knowledge, information search, knowledge management, database design, information modeling andobject-oriented analysis. In particular, Gather company in their researches of IT-market attributed the use of taxonomy/ontology inhis area. Consequently, research of syntactic ontological structures of KB, construction and research of optimal algorithm for syntacticanalysis of Ukrainian language texts and the development of software-algorithmic means of content, automatic referencing oftexts, gathering knowledge, translation etc. are relevant.Objective. The goal of the work develop a software system for formalizing the rules of syntax of the Ukrainian language in theform of an ontological basis of knowledge for the purpose of its use for working out natural language texts in the Ukrainian language.Method. Methods of solving the problem of creating a consolidated resource based on ontological KB were chosen decisiontrees, IDEF5 methodology and ontology construction methodology. The results of syntactic analysis work are taken into account byassociative-semantic context analysis to optimize the process of constructing associative context relationships between words andsentence combinations within the hierarchical network of ontological BB.Results. A consolidated information resource is created – an ontological KB of parsing analysis of Ukrainian-language textdocuments with the help of Protégé 3.4.7.Conclusions. The method of data extraction based on ontological BZ and FPGA language is developed for the further developmentof a consolidated information resource for the syntactic elaboration of text documents. As a result, an ontological type of KBwith FPSM was created. The syntactic structure of the input sentence is the foundation and frame for the next, not less important step– semantic analysis. This ontological KB of the consolidated LR of syntactic elaboration of Ukrainian-language text documentsserves as a powerful basis for further development of an automated IS for parsing Ukrainian-language texts
