Because your model will return a score between 0 and 1 for each label, you’ll determine a positive or negative result based on that score. Finally, you add the component to the pipeline using .add_pipe(), with the last parameter signifying that this component should be added to the end of the pipeline. For a deep dive into many of these features, check out Natural Language Processing With spaCy. Now you’ll begin training on batches of data: Now, for each iteration that is specified in the train_model() signature, you create an empty dictionary called loss that will be updated and used by nlp.update(). Sentiment Analysis¶ Now, we'll use sentiment analysis to describe what proportion of lyrics of these artists are positive, negative or neutral.
