Onlinу recruitment systems have accumulated a huge amount of data on the real labor market in recent years. Of particular interest to the study are the data on the real requirements of the labor market contained in the texts of online vacancies, as well as the process of extracting and structuring them for further analysis and use. The stage of compiling an up-to-date list of requirements for a position profile in the recruitment process is very time-consuming and requires a large amount of effort from an HR specialist related to monitoring changes in entire industries and professions, as well as analyzing relevance of existing requirements on the market. In this article, the author proposes a conceptual model of a recommendation system that allows one to reduce the burden on an HR specialist at the stage of forming an up-to-date list of requirements for a position profile in the recruitment process. The model is based on a combination of the following components: a graph model of labor market requirements based on the ESCO taxonomy adapted for the Russian language; and an intelligent method of forming recommendations for compiling an up-to-date list of requirements in the recruitment process based on neural network models of the language on the architecture of transformers, ESCO skills taxonomy and corpus online vacancies of the Russian labor market. The article also provides a conceptual algorithm for the work of the recommendation system and possible options for recommendations on updating the list of requirements of the position profile in the recruitment process based on an analysis of the needs of the real labor market.
