Boilerplate text analysis - text mining

Dear community 

I'm new to text mining with RM and would like to know, if it's even possible to build a process in RM which suits my research question. I would like to create a process which searches for boilerplate language in documents. 

In detail I'd like to input management reports from different companies (pdf files) and compare them regarding the usage of boilerplate language/ templates. (If they are using the same sentences or passages in their reports only with other numbers or years) 

I would really appreciate every idea

Thank you very much in advance!
