Frage
I'm studying about Sentiment analysis. What is the purpose of using Document Level, Sentence Level and Aspect Level?
I read this definition in Web Data Mining book by Bing liu.
In this book it was stated that,
Sentence Level sentiment analysis is to classify a sentence to negative, positive, neutral class.
Document level sentiment analysis to classify a document.
Aspect Level sentiment analysis is to classify each aspect of entity mentioned in a review.
Thanks.
