Which algorithm is best suited for sentiment analysis?
For a non-neural network based models, DeepForest seems to be the best bet. With extensive research happening on both neural network and non-neural network-based models, the accuracy of sentiment analysis and classification tasks is destined to improve.
Why SVM is used in sentiment analysis?
Support vector machine (SVM) is a learning technique that performs well on sentiment classification. Non-negative linear combination of multiple kernels is an alternative, and the performance of sentiment classification can be enhanced when the suitable kernels are combined.

How to build a movie review sentiment classifier?
Here we will build a classifier that is able to distinguish movie reviews as being either positive o r negative. For that, we will use Large Movie Review Dataset v1.0 [2] of IMDB movie reviews.
How is sentiment analysis used in natural language processing?
Sentiment analysis, an important area in Natural Language Processing, is the process of automatically detecting affective states of text. Sentiment analysis is widely applied to voice-of-customer materials such as product reviews in online shopping websites like Amazon, movie reviews or social media.
How to build sentiment classifier using scikit-learn?
All reviews for a given movie are either in train or test set but not in both, in order to avoid test accuracy gain by memorizing movie-specific terms. After the dataset has been downloaded and extracted from archive we have to transform it into a more suitable form for feeding it into a machine learning model for training.
