In this paper, for the first time, the accuracy of solving the problem of recognizing named entities of the ADR type for the PsyTAR corpus was evaluated. Initially, the corpus contained markup for solving the problems of detecting entities, classifying their presence, and linking entities. We carried out additional marking of the corpus. A neural network based on the XLM-RoBERTa architecture was used as a model for entity recognition. The results of this model are also presented in comparison with the published results for this corpus on other tasks.
