有什么高效的算法对 url 中的路径参数做模式识别分类么

[etoahn]

比如我有以下 url(输入)

https://www.showcase.com/user/home

https://www.showcase.com/bill/BlKLSJDFLJERSDF
https://www.showcase.com/bill/BSERlKLSSDFEJSDF
https://www.showcase.com/bill/BSDREWRDF
https://www.showcase.com/bill/BSERDWEDFEJSDF # 类似 url 可能有 100+个

https://www.showcase.com/bill/BlKLSJDFLJERSDF/detail
https://www.showcase.com/bill/BSERlKLSSDFEJSDF/detail
https://www.showcase.com/bill/BSDREWRDF/detail
https://www.showcase.com/bill/BSERDWEDFEJSDF/detail # 类似 url 可能有 100+个


https://www.showcase.com/topic/234566833245234566
https://www.showcase.com/topic/200000234523456683
https://www.showcase.com/topic/2586683567243w56324 # 类似 url 可能有 100+个


# 其它大量 url ， 正则规则不固定，只能通过统计分析

分类为(输出)

https://www.showcase.com/user/home
https://www.showcase.com/bill/{param} 
https://www.showcase.com/bill/{param}/detail
https://www.showcase.com/topic/{param}

暂时只想到用模式识别， 不知大佬有无其它方法

分词处理，有那种分词处理算法

这不是正则吗
