Datefinder Module特定字符串上的陌生人行为 [英] Datefinder Module Stranger behavior on particular string

问题描述

我有两个字符串:

s1 = 'Agreement dated on March 9, 2007'
s2 = 'Agreement signed on March 9, 2007'

我在字符串上运行以下代码

I run below code on the string

import datefinder
matches =datefinder.find_dates(s1) ## or s2
for match in matches:
       print (match)

s2给了我想要的结果，但s1却没有，因为它包含带日期的单词.

s2 gives me desired result but s1 doesn't as it contains the word dated.

P.S.我使用过日期查找器，因为我有多种日期格式，因此需要编写多个正则表达式.只是针对这种例外情况，效果很好

P.S. I have used datefinder as I had multiple date formats and hence need to write multiple regex. This worked well just for this exception

知道为什么会有这种奇怪的行为吗?

Any idea why this strange behavior?

推荐答案

这不是datefinder中的错误.

日期 是正则表达式代码中的令牌模式之一:

dated is one of the token patterns in the regex code:

EXTRA_TOKENS_PATTERN = r由于|在|上|在|标准|白天|节约|时间|日期| 已 |在|到|通过|之间|直到|当天"

EXTRA_TOKENS_PATTERN = r"due|by|on|during|standard|daylight|savings|time|date|dated|of|to|through|between|until|at|day"

您可能需要编写一个正则表达式来传递问题或成为解决该问题的项目的参与者.

You will likely need to write a regex to by pass the issue or become a contributor to the project to fix the issue.
