Which technique is used for sentiment analysis supervised learning or unsupervised learning?
And when is unsupervised learning a better choice for sentiment analysis?
Unsupervised learning is a better choice for sentiment analysis when we don't have labeled data available. For example, if we have a dataset of product reviews but we don't have labels for whether they are positive or negative, then we can use unsupervised learning to group similar reviews together based on their topics and keywords. This will give us insight into what the customers are talking about and how they feel about the product.
