具體描述

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.

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...

粗略的看了一遍，最后几章几乎就是过了一眼。有很多知识是暂时看不懂，过一段时间需要重读一遍。没有提到中文的处理。不过大体的流程和原理应该是差不多的，书里提到了以下的技术，中文处理应该也同样需要，把看到大概的内容记录如下 1.Tokenize 2.Tagging，也就是给出词性...

不过书中还用了一部分篇幅穿插讲解python最基础的编程技术，就不太让人理解了。读这种书肯定是先对python有一定的了解了。这一点有点定位不清啊。整体的还是很不错的。为什么发表不了，抱怨我评论太短。 150字还短么
