The purpose of this article is to discuss the actual problem of using smart systems, metaphorically called “artificial intelligence technology”, “virtual reality”, etc. In addition to the terminological problem, special attention is paid at such important aspect as “digital transformation”, which is the fourth stage of automation of activity, including that of libraries. In digital transformation, the main thing is the transformation of the regulatory framework, in particular, putting it in order. Without terminologization, algorithmization and creation of an ontology of the subject area of information and library activities, it is impossible to create a professional smart system. The study bases on the categorical tensor approach. It shows that the main trend in the development of digital innovations in library and information activities is smartization, mediatization and virtualization. The basic properties of smart systems that allow analyzing the authenticity of scientific and technical texts and identifying authentic texts in them are revealed. It is noted that compression and visualization of analyzed texts can enable librarians to carry out information analysis of publicly available documents, for example, abstracts of dissertations in order to identify detonation data located in the peripheral zone. The emergence of smart systems in the form of a GPT chatbot (Generative Pretrained Transformer) will reflect in the use of professional smart systems, which, unlike anti-plagiarism systems, will identify scientific media products at the semiotic level. The presented results can intensify the discussion on the topic under consideration.
