python中NLTK中的POS标记中的zip文件错误 [英] bad zip file error in POS tagging in NLTK in python

问题描述

我是python和NLTK的新手..我想在其中进行单词标记和POS标记.我在Ubuntu 14.04中安装了默认的python 2.7.6的Nltk 3.0，首先我尝试对一个简单的句子进行标记化但是，我收到一个错误消息，提示"BadZipfile:文件不是zip文件".如何解决此问题???

I am new to python and NLTK ..I want to do word tokenization and POS Tagging in this.I installed Nltk 3.0 in my Ubuntu 14.04 having a default python 2.7.6.First I tried to do tokenization of a simple sentence.But I am getting an error,telling that "BadZipfile: File is not a zip file".How to solve this????

..另一个疑问.当我安装Nltk数据时(使用命令行)，我给出的路径为"/usr/share/nltk_data".由于某些错误而无法安装某些程序包.但是当我使用命令"nltk.data"进行检查时，它显示了其他路径.路径"和其他路径实际上是无效的.为什么?

..One more doubt..i.e. i gave path as "/usr/share/nltk_data" when i installed Nltk data (using command line).Some of the pakages couldnt be installed due to some errors.But it shows other paths when i cheked using command "nltk.data.path" and the other paths are invalid actually.. why???

我有1000个文本文件.如何编写一个用于标记和POS标记的程序，将这些文件作为python输入..我不知道..请帮助我...

I have got 1000 text files.How to code a program for tokenization and POS tagging for this much files together as a input in python..i dont know.. Please help me...

下面以相同的顺序给出了我在python解释器中使用命令的方式
