Собрано 197 отзывов студентов на 129 элективных дисциплин Тюменского государственного университета. Проведен сравнительный анализ методов извлечения ключевых слов: статистических TF-IDF, RAKE и YAKE; контекстуального KeyBERT; основанного на графах TextRank. На собранных отзывах, сгруппированных по элективным дисциплинам, наибольшую F1-меру BERTScore с результатом 79 % показал метод RAKE. Путем сбора данных из открытых источников сформирован датасет с 2210 русскоязычными отзывами на курсы различных образовательных платформ. Описано обучение моделей машинного обучения для анализа тональности: метода опорных векторов, логистической регрессии и основанных на архитектуре Transformers, полученных с ресурса Hugging Face, сравнение на вручную размеченной части собранных отзывов. После дообучения модели rubert-base-cased macro-усредненная F1-мера показала 71,6 %. Классификация осуществляется по трем классам (негативный, нейтральный, положительный) не для всего текста отзыва, а в отдельности для каждого предложения из этого текста. Представлена реализация базы данных и информационной системы сбора и обработки отзывов студентов на изученные элективные дисциплины. Модель для анализа тональности отзыва вынесена в отдельный микросервис, связь с которым осуществляется через интерфейс свободно распространяемого Python-фреймворка FastAPI. Запущенная информационная система призвана помочь студентам выбирать элективы, опираясь на большее количество качественных данных, а преподавателям и администрации вуза – делать выводы для дальнейшей трансформации образовательного пространства, учитывая мнение обучающихся.</p></abstract><trans-abstract xml:lang="en"><p>This article provides a review of publications on the analysis of students’ satisfaction with the educational process based on natural language processing methods. 197 student feedback on 129 elective disciplines at University of Tyumen was collected. A comparative analysis of keyword extraction methods was conducted: statistical TF-IDF, RAKE and YAKE; contextual KeyBERT; graph-based TextRank. On the collected reviews, grouped by elective disciplines, the RAKE method had the highest F1 BERTScore with 79 %. By parsing open sources, a dataset with 2210 Russian-language reviews for courses of different educational platforms was formed. Machine learning methods for sentiment analysis were described: support vector machines, logistic regression and based on Transformers, comparison on the manually marked part of the collected reviews. After fine-tuning on the rubert-base-cased model macro-averaged F1- score became 71.6 %. Classification into three classes (negative, neutral, positive) is not performed for the whole text of the review, but separately for each sentence from that text. The implementation of a database and information system for collecting and analyzing student feedback on the studied elective courses are presented. The model for sentiment analysis of the feedback is put into a separate microservice, which is communicated through an interface of the freely distributed Python framework FastAPI. The information system is designed to help students choose electives based on more qualitative data, and teachers and university administration ‑ to draw conclusions for further transformation of the educational space, taking into account students’ opinions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>выделение ключевых слов</kwd><kwd>анализ тональности</kwd><kwd>отзывы студентов</kwd><kwd>индивидуальные образовательные траектории</kwd><kwd>элективные дисциплины</kwd><kwd>информационная система</kwd></kwd-group><kwd-group xml:lang="en"><kwd>keyword extraction</kwd><kwd>sentiment analysis</kwd><kwd>student feedback</kwd><kwd>individual learning trajectories</kwd><kwd>electives</kwd><kwd>information system</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Федорова Н.
