Tutorial On Keras Tokenizer For Text Classification in NLP To do this we will make use of the Reuters data set that can be directly imported from the Keras library or can be downloaded from Kaggle. This data set contains 11,228 newswires from Reuters having 46 topics as labels. We will make use of different modes present in Keras tokenizer and will build deep neural networks for classification.

Datasets - keras-contrib IMDB Movie reviews sentiment classification. Dataset of 25,000 movies reviews from IMDB, labeled by sentiment (positive/negative). Reviews have been preprocessed, and each review is encoded as a sequence of word indexes (integers). For convenience, words are indexed by overall frequency in the dataset, so that for instance the integer "3" encodes the 3rd most frequent word in the data.
