Tutorial On Keras Tokenizer For Text Classification in NLP

Tutorial On Keras Tokenizer For Text Classification in NLP - exploring Keras tokenizer through which we will convert the texts into sequences. In this article, we will explore Keras tokenizer through which we will convert the texts into sequences that can be further fed to the predictive model. 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.

Natural language processing has many different applications like  Text Classification, Informal Retrieval, POS Tagging, etc. Almost all tasks in NLP, we need to deal with a large volume of texts. Since machines do not understand the text we need to transform it in a way that machine can interpret it. Therefore we convert texts in the form of vectors. There are many different methods to do this conversion like count vectorizer,  TF-IDF vectorizer, and also Keras have tokenizers that serve the same purpose.

We will make use of different modes present in Keras tokenizer and will build  deep neural networks for  classification.

Hands-on Guide to Pattern - A Python Tool for Effective Text Processing and Data Mining

Pattern is an open-source python library and performs different NLP tasks. It is mostly used for text processing due to various functionalities it provides. Text Processing mainly requires Natural Language Processing( NLP), which is processing the data in a useful way so that the machine can understand the Human Language with the help of an application or product. Using NLP we can derive some information from the textual data such as sentiment, polarity, etc.
