The aim of the study is to design an electronic terminographic product in the form of a terminological data bank (TDB) “Classification Parameters of Phraseological Units” with consistent implementation of infological and datological stages. The object in the study is the TDB, the focus is terms for designation of types of phraseological units (PU), which actively function in Ukrainian and Russian linguistics in the 2nd half of the 20th century to 2020. The methodology of the study is based on theoretical foundations of phraseology, terminology, applied linguistics, and computer terminography (linguistic database/data bank technology). The general and specific scientific methods are used: analysis and synthesis, ascent from the abstract to the concrete, classification, definitional analysis, identification, linguistic observation and description, selection, elements of a statistical method. The infological stage is related to the solution of a set of information problems: 1) definition of the principle of regularization of terms of phraseology, 2) selection of terms with the archeseme “phraseoclassification type” from scientific literature in order to form an alphabetical register, 3) establishment of the composition of the dedicated terminology subsystems, 4) description of terminology subsystems, 5) creation of an electronic catalog of terms for further computer processing of collected information. The main principle of systematization is the thesaurus: “terminological system – terminological microsystem – terminological subsystem – term”. The next step is to develop a datalogical scheme, which is a system of tables whose fields display information about the described terms in the form of data, for example: number, term, terminology subsystem, scientific source, definition, illustration, paradigm relations of the term. The TDB modeled in the work is a special terminology dictionary (monolingual (Ukrainian) in terms of the number of languages involved), which has 113 terms to denote types of PUs and covers 17 classifications of PUs. The TDB “Classification Parameters of Phraseological Units” is positioned as an electronic terminographic product created for storage of information, optimization and intensification of system research on fundamental issues of phraseology and phraseography, works devoted to problems of comprehensive analysis and parameterization of PUs. The prospect of the study is to create a Russian-language version of this terminographic product.
