Designing an agent system for collecting and dysplaying data on scientific publications of BRICS union countries

The paper is devoted to the design of an agent system for collecting and displaying data on scientific publications of the BRICS Union countries. Therefore, the aim of the work is to design a system that allows you to collect information from databases that contain information about scientific publications published in leading journals and provide statistical information about the publication activity of the BRICS countries in a convenient form for analysis. The site natureindex.com is selected as an information resource from which the required data will be extracted. The selected Nature Index resource contains links to publications of each country in a particular journal. In the designed system, it is required to develop an agent program that should collect links to publications and journal titles of these publications from the site. The article presents the requirements for the system, describes the structure of the selected information resource. The design of each part of the system is carried out: the database model is described, the algorithm of the agent program is presented and a class diagram for its further implementation is given, the choice of a three-level architecture of the web application is justified and user interface layouts are created to display information according to the advanced requirements and use cases. The design results will be used in the future to develop the described system.
