New and improved existing IAA management models have been developed, taking into account the possibilities of the scenario approach, features of information resources, characteristics of information flows circulating in computer networks; information technologies: automatic formation of the subject area model based on scanning of text resources and creation of a network of concepts; integration of graphical research tools and ontologies for the study of textual information spaces. An improved model of the system of monitoring, aggregation and generalization of information is proposed, which is based on the principle of filtering the results, and a new principle of building an adaptive documentary repository, which is to adjust to the information needs of users. A set of software modules for automated construction and visualization of a network of subject area concepts has been developed, with the help of which news from online media have been processed and a network of subject area concepts has been created. The results of research indicate the need for the development of methods and information technologies for processing large volumes of information flows (Big Data), methods of their integration, methods and means of meaningful analysis of information in the implementation of IAA.   Product Description popup.authors popup.nrat_date 2021-03-02 Close
