Information technology for identifying terms and project artifacts in the requirements for the information system

The object of the study is the activity «Determining system requirements» of the «Determining system requirements» process. It has been determined that one of the best ways to carry out this activity is to use human-machine or machine-based methods of defining and analyzing system requirements. But the existing instrumental means of defining and managing the requirements for IT products do not allow automating the execution of the relevant work. Therefore, conducting research on the application of artificial intelligence methods and, in particular, natural language processing methods for the definition and analysis of textual publications of system requirements is relevant. The main goal of the research is the development of information technology for identifying terms and artifacts of the project in the requirements for the information system. The formal basis of this technology was defined, which is based on the application of lemmatization methods. A description of the architecture of information technology has been developed. A technological stack for the development of a service that implements this technology has been defined. Features of the development of the most important software modules of this service are considered. An experimental verification of the obtained results of information technology development was carried out. Ukrainian and English localizations of the «Football» information system were used for this check. This system implements the minimally necessary set of functions that allow automating the solution of the tasks of planning and accounting for football matches. During the experimental verification, it was established that the service, which implements the developed information technology, successfully solves the problem of identifying project terms and artifacts in the requirements for the information system and provides relevant results for solving this problem for translations of the same requirement in different languages.
