This book offers a highly accessible introduction to Natural Language Processing, the field that underpins a variety of language technologies, ranging from predictive text and email filtering to automatic summarization and translation. With Natural Language Processing with Python, you'll learn how to write Python programs to 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, 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

Perfect for individual study, or as a classroom and workshop textbook, 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, documenting endangered languages, or if you are simply curious to have a programmer's perspective on how human language works, you will find Natural Language Processing with Python both fascinating and immensely useful.

结合Python的语言特性，循序渐进介绍了很多自然语言处理方面的知识，以及如何使用nltk进行NLP。再次体会到Python在文本处理方面有着很多先天优势。不过，如果Python较为熟悉，这本书的很多章节可以略过。

现在的研究方向是NLP，由于以前没有相关的基础知识（特别是数学很差劲），导致学习起来觉得困难重重。后来了解到Python语言在NLP领域有较好的应用空间，于是就学习了Python的基础知识，然后就发现了此书的中文翻译版，于是打印出来认真拜读。它的特点是：实例多（虽然木有中文...

入门级别的书，如果你对Python不太了解，里面还有介绍Python基本语法的内容。讲的主要是针对英文的自然语言处理，关于中文的基本没有，但大致思路是相通的。这本书是基于python2的。里面有些代码已经运行不了了。但是作者在http://www.nltk.org/book/ 有本书基于python3的修订...
