Пока вы со мной лясы тут точите, Moody уже забацала все практически:
Coronavirus Pulse uses machine learning and natural language processing to find English-language news articles related to COVID-19 and identify companies, sector-specific themes, and events mentioned in each article. It then assigns "article" and "credit" sentiment to each news item by evaluating the overall context of the story. Adverse, neutral, or positive "article" sentiment is assigned based on an approach that captures reputational, political, medical, and macroeconomic risks. Meanwhile, adverse "credit" sentiment is assigned to each item based on an approach developed for use in the Moody’s Analytics Credit Sentiment Score™ solution, which captures credit-relevant risks.
Developed by the Moody’s Analytics Accelerator, Coronavirus Pulse is built on a transferable framework of artificial intelligence models and is custom-trained using relevant data from across Moody’s Analytics. It is part of an evolving suite of solutions that use advanced machine learning techniques to scan unstructured data and deliver news sentiment analysis.https://finance.yahoo.com/news/moody-analytics-launches-tool-covid-100000975.html
