识别任意日期字符串 [英] Recognise an arbitrary date string

问题描述

我需要能够识别日期字符串。如果我无法区分月份和日期（例如12/12/10），我只需要将字符串分类为日期，而不是将其转换为Date对象。所以，这真的是一个分类，而不是解析问题。

I need to be able to recognise date strings. It doesn't matter if I can not distinguish between month and date (e.g. 12/12/10), I just need to classify the string as being a date, rather than converting it to a Date object. So, this is really a classification rather than parsing problem.

我将会有一些文字，例如：

I will have pieces of text such as:

bla bla bla bla 12 Jan 09 bla bla bla
01/04/10 bla bla bla

"bla bla bla bla 12 Jan 09 bla bla bla 01/04/10 bla bla bla"

，我需要能够识别每个日期字符串的开始和结束边界。

and I need to be able to recognise the start and end boundary for each date string within.

我想知道是否有人知道任何java图书馆可以做到这一点。到目前为止，我的google-fu还没有提出任何东西。

I was wondering if anyone knew of any java libraries that can do this. My google-fu hasn't come up with anything so far.

更新：我需要能够识别尽可能广泛的代表日期的方式。当然，天真的解决方案可能是为每个可想到的格式编写一个if语句，但是使用经过训练的模型的模式识别方法是理想的我之后。

UPDATE: I need to be able to recognise the widest possible set of ways of representing a dates. Of course the naive solution might be to write an if statement for every conceivable format, but a pattern recognition approach, with a trained model, is ideally what I'm after.

推荐答案

使用 JChronic

您可能想使用 DateParser2 。
