python - nltk.concordance 最多提供 25 行，无论我如何更改该参数

问题描述

所以我开始通过 nltk book 学习 NLP，似乎我立即遇到了一个以前没有人提到过的问题。

让我们从 nltk.book 导入数据，就像书上说的那样：

from nltk.book import *

现在我想继续书中的例子：

text1.concordance("monstrous")

给我：

到目前为止，一切都很好。现在我想知道《白whale鲸记》中单词的一致性。

什么，不可能是对的。“鲸鱼”这个词不可能在《白鲸记》中只出现 25 次。“它”这个词怎么说？

text1.concordance("it")

好的，让我们增加显示的行数：

text1.concordance("it", lines=100)
Displaying 25 of 25 matches:

怎么减呢？

text1.concordance("it", lines=10)
Displaying 10 of 25 matches:

它要我相信“它”这个词只出现了 25 次？虽然这绝对是一个故障，但争论会变得更糟width（它根本没有考虑到它）。

我使用 nltk 的系统：

赢10 64位；

Python 3.6.5 32 位

发生了什么事，我该如何解决？

解决方案

这似乎是 NLTK 3.3 的一个错误。

在源代码中，行

concordance_list = self.find_concordance(word, width=80, lines=25)

强制结果为 <= 25 行，宽度 <= 80 并且应该是

concordance_list = self.find_concordance(word, width=width, lines=lines)

最简单的解决方法是将您的 NLTK 安装降级到 3.2 版（其中concordance具有预期的行为）。
