WebAug 15, 2024 · This is a dataset for binary sentiment classification containing substantially more data than previous benchmark datasets. We provide a set of 25,000 highly polar movie reviews for training, and 25,000 for testing. There is additional unlabeled data for use as well. Raw text and already processed bag of words formats are provided. WebJun 14, 2024 · As discussed above LSTM facilitated us to give a sentence as an input for prediction rather than just one word, which is much more convenient in NLP and makes it more efficient. To conclude, this article explains the use of LSTM for text classification and the code for it using python and Keras libraries. Author Shraddha Shekhar
