如何使用google ngram查看器和python获取句子的出现情况？

Question

简短的背景:我试着用Peter Norvig在python中增强拼写校正器。在这个意义上，我需要出现一个句子(最多3-4个单词)…Ngram viewer from Google会对我有很大帮助，但我不知道如何通过API或其他东西获得值。

伪代码：

# Sentence without meaning but word for word correct.
>> occurrence("were are you")
0.0000000978

# Sentence that makes sense
>> occurrence("where are you")
0.000148

# Then my method should return the sentence with the highest value. (But thats not the problem)

对不起，我的英语:-D谢谢！

Answer 1

他们实际上有一个未记录的api。

import requests
import json

term = "where are you"
url =f"https://books.google.com/ngrams/json?content={term}&year_start=1800&year_end=2000&corpus=26&smoothing=3"
resp = requests.get(url)
if resp.ok:
  results = json.loads(resp.content)

results[0]['timeseries']拥有您需要的频率：

[2.854326695000964e-07,
 3.4926038665616944e-07,
 3.3916604043800663e-07,
 ...]
