Natural Language Processing with Python

This Book will help you gain practical skills in natural language processing using the Python programming language and the Natural Language Toolkit (NLTK) open-source library. If you’re interested in developing web applications, analyzing multilingual news sources, or documenting endangered languages or are curious about a programmer’s perspective on how human language works, you’ll find both fascinating and immensely useful.

This book offers a highly accessible introduction to natural language processing, the field that supports a variety of language technologies, from predictive text and email filtering to automatic summarization and translation. With it, you’ll learn how to write Python programs that work with large collections of unstructured text. You’ll access richly annotated datasets using a comprehensive range of linguistic data structures, and you’ll understand the main algorithms for analyzing the content and structure of written communication.

Packed with examples and exercises, Natural Language Processing with Python will help you:

  • Extract information from unstructured text, either to guess the topic or identify “named entities”
  • Analyze linguistic structure in text, including parsing and semantic analysis
  • Access popular linguistic databases, including WordNet and treebanks
  • Integrate techniques drawn from fields as diverse as linguistics and artificial intelligence

    What You Will Learn By digging into the material presented here, you will learn:
    • How simple programs can help you manipulate and analyze language data, and
    how to write these programs
    • How key concepts from NLP and linguistics are used to describe and analyze
    language
    • How data structures and algorithms are used in NLP
    • How language data is stored in standard formats, and how data can be used to
    evaluate the performance of NLP techniques
