Over 80 practical recipes on natural language processing techniques using Python's NLTK 3.0 In Detail This book will show you the essential techniques of text and language processing. Starting with tokenization, stemming, and the WordNet dictionary, you'll progress to part-of-speech tagging, phrase chunking, and named entity recognition. You'll learn how various text corpora are organized, as well as how to create your own custom corpus. Then, you'll move onto text classification with a focus on sentiment analysis. And because NLP can be computationally expensive on large bodies of text, you'll try a few methods for distributed text processing. Finally, you'll be introduced to a number of other small but complementary Python libraries for text analysis, cleaning, and parsing. This cookbook provides simple, straightforward examples so you can quickly learn text processing with Python and NLTK. What You Will Learn Tokenize text into sentences, and sentences into words Look up words in the WordNet dictionary Apply spelling correction and word replacement Access the built-in text corpora and create your own custom corpus Tag words with parts of speech Chunk phrases and recognize named entities Grammatically transform phrases and chunks Classify text and perform sentiment analysis
