Klevu’s algorithms aim to identify positive sentiments. This component depends on Natural Language Processing (NLP) rules, not only synonyms/positive keywords.
For example. "Great" is positive sentiment but when you write like "not so great", the component should not extract "great" from reviews.
To handle such scenarios, we can not only rely on keywords matching but it requires process beyond that and that's what we do.Further to this we don't consider product ratings while extracting positive sentiment from reviews. Please note that this feature is only available as part of the premium-plus and/or enterprise plan. You are required to submit a feed containing a product ID and the related reviews.
