Book description
Get to grips with solving real-world NLP problems, such as dependency parsing, information extraction, topic modeling, and text data visualization
Key Features
- Analyze varying complexities of text using popular Python packages such as NLTK, spaCy, sklearn, and gensim
- Implement common and not-so-common linguistic processing tasks using Python libraries
- Overcome the common challenges faced while implementing NLP pipelines
Book Description
Python is the most widely used language for natural language processing (NLP) thanks to its extensive tools and libraries for analyzing text and extracting computer-usable data. This book will take you through a range of techniques for text processing, from basics such as parsing the parts of speech to complex topics such as topic modeling, text classification, and visualization.
Starting with an overview of NLP, the book presents recipes for dividing text into sentences, stemming and lemmatization, removing stopwords, and parts of speech tagging to help you to prepare your data. You’ll then learn ways of extracting and representing grammatical information, such as dependency parsing and anaphora resolution, discover different ways of representing the semantics using bag-of-words, TF-IDF, word embeddings, and BERT, and develop skills for text classification using keywords, SVMs, LSTMs, and other techniques. As you advance, you’ll also see how to extract information from text, implement unsupervised and supervised techniques for topic modeling, and perform topic modeling of short texts, such as tweets. Additionally, the book shows you how to develop chatbots using NLTK and Rasa and visualize text data.
By the end of this NLP book, you’ll have developed the skills to use a powerful set of tools for text processing.
