description: This work is dedicated to the study of various methods of text classification and sentiment analysis of texts published on the internet, as well as the development of effective approaches for solving this problem based on modern machine learning methods. Tasks that were solved during the research: Collection and preprocessing of text data. Reviews of various products were collected from the online store www.wildberries.ru. Preprocessing operations such as stop-word removal, lemmatization, and text cleaning from specific symbols were performed. Training a model for determining the category of the review. A machine learning model was developed for classifying reviews into categories. Training a model for determining the sentiment of the review. A machine learning model was developed for sentiment analysis of reviews. Output of the classification and sentiment analysis results of texts. After training the models, testing was performed on a test set of data. The results showed a high accuracy of text classification and sentiment analysis. As a result of the research, effective algorithms for text classification and sentiment analysis were developed, which can be used for automatic processing and analysis of large volumes of data from the Internet.
