This paper is devoted to the presentation of approaches applied to the development of an information-expert system for the investigation of structural-mechanical properties of materials. The demand for such a system follows from the necessity of the solution of an important technological problem, namely, automation of the process of developing essential products with rigidly regulated functional properties. A general architecture of the system and theoretical aspects of the development of its basic components are described, along with subsystems of automation of workflow processes, automatic classification, and three-dimensional visualization.

Thematic information search is used in various fields of activity. The use of thematic analysis tools to search for conferences allows you to increase the completeness of the search and coverage of conferences, helps to expand the circle of scientific communication of young scientists and the formation of closer scientific connections. The search algorithms developed by the authors use the co-authorship graph and the reference set of authors. The set can be obtained using methods of thematic search of experts or based on given samples. The developed algorithms are language insensitive and take into account the authority of conferences in the scientific community. Approbation was carried out on the data of the scientometric system IAS ISTINA.
