CONTENTS
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 pro¬
grams 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
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 multi¬
lingual news sources, or documenting endangered languages
—
or if you're simply curious to have a programmer's perspective
on how human language works
—
you'll find Natural Language
Processing with Python both fascinating and immensely useful. |
