绘制单词频率和NLTK [英] Plotting words frequency and NLTK

问题描述

我有一个包含多个单词的文件，我想计算文档中每个单词的频率并将其绘制出来. 但是，我的情节没有显示结果. x-axis必须包含单词，而y-axis必须包含频率. 我正在使用NLTK，NumPy和Matplotlib

I have a file with various words, which I want to count the frequency of each word in the document and plot it. However, my plot is not showing results. The x-axis must contain the words, and the y-axis the frequency. I am using NLTK, NumPy and Matplotlib

这是我的代码，也许我做错了事

Here's my code, maybe I did something wrong

def graph():
    f = open("file.txt", "r")
    inputfile = f.read()
    words = nltk.tokenize.word_tokenize(inputfile)
    count = set(words)
    dic = nltk.FreqDist(words)
    FreqDist(f).plot(50, cumulative=False)
    f.close()

预先感谢您的帮助

推荐答案

def graph():
  f = open("file.txt", "r")
  inputfile = f.read()
  tokens = nltk.tokenize.word_tokenize(inputfile)
  fd = nltk.FreqDist(tokens)
  fd.plot(30,cumulative=False)

您可以通过更改plot()的参数来玩图

You can play with the graph by altering the parameters to the plot()
