Is Sentiment Analysis supported? Maybe there are some examples?

theolivenbaum commented 4 years ago

Hi @KSemenenko,

We've no specific examples on sentiment analysis, but you could use the FastText classifier model for it (see the text classification sample code).

There are a few examples online on how to use FastText for sentiment analysis, such as https://towardsdatascience.com/twitter-sentiment-analysis-using-fasttext-9ccd04465597.

The main idea is to feed your training data in with three possible labels (such as 'POSITIVE', 'NEGATIVE' or 'NEUTRAL'), and let the model learn from it.
