Overview of this book

Natural language processing (NLP) has found its application in various domains, such as web search, advertisements, and customer services, and with the help of deep learning, we can enhance its performances in these areas. Hands-On Natural Language Processing with Python teaches you how to leverage deep learning models for performing various NLP tasks, along with best practices in dealing with today’s NLP challenges. To begin with, you will understand the core concepts of NLP and deep learning, such as Convolutional Neural Networks (CNNs), recurrent neural networks (RNNs), semantic embedding, Word2vec, and more. You will learn how to perform each and every task of NLP using neural networks, in which you will train and deploy neural networks in your NLP applications. You will get accustomed to using RNNs and CNNs in various application areas, such as text classification and sequence labeling, which are essential in the application of sentiment analysis, customer service chatbots, and anomaly detection. You will be equipped with practical knowledge in order to implement deep learning in your linguistic applications using Python's popular deep learning library, TensorFlow. By the end of this book, you will be well versed in building deep learning-backed NLP applications, along with overcoming NLP challenges with best practices developed by domain experts.

Data

In order to build our search and retrieval system, we will use the same data for training and testing. We will use the Quora duplicate questions data for building our approach to searching and retrieving. The task of the Quora duplicate question pair is to determine whether two pairs of questions have the same meaning. The data contains a pair of questions and a ground truth label, marked by a human expert, mentioning whether the pairs of questions are duplicates. The ground truth data provided also mentions that these labels are subjective, meaning that not all human experts might agree on whether the pair of questions is similar. Hence, the data should be taken as informed, and not 100% accurate, due to the inherent subjectivity in the text data.
