Question

我是python和NLTK的新手。我想在这里做单词标记化和POS标记。我在我的Ubuntu 14.04中安装了Nltk 3.0，默认python 2.7.6。首先我尝试对一个简单的句子进行标记化但是我收到一个错误，告诉他＆＃34; BadZipfile：文件不是一个zip文件＆＃34;。如何解决这个问题????

..还有一个疑问......呃。我给了道路＆＃34; / usr / share / nltk_data＆＃34;当我安装Nltk数据时（使用命令行）。由于某些错误，某些pakages无法安装。但是当我使用命令＆＃34; nltk.data.path＆＃34;时，它显示了其他路径。其他路径实际上是无效的..为什么???

我有1000个文本文件。如何将这么多文件的标记化和POS标记编码一起作为python中的输入...我不知道..请帮助我......

我在python解释器中使用命令的方式在下面以相同的顺序给出

>>> from nltk import pos_tag, word_tokenize
>>> sentence = "Hello my name is Derek. I live in Salt Lake city."
>>> sentence

Answer 1

你显然还没有download_corpora.py（成功）。

Answer 2

我已经解决了与在stackoverflow上关注此问题相同的问题。

基本上，检查您的NLTK版本。如果高于v3.2，请使用以下命令行：

nltk.download('averaged_perceptron_tagger')

对我有用。
