C++ libraries for text preprocessing?

Question

C++ / C#

What libraries could be used to implement text preprocessing?
For example:
1. Replace abbreviated words (thousand - millennium)
2. Distinguish dates, distinguish between abbreviation and end of sentence points (11/07/2017 - remake in "November 7, 2017", i.e. - in "that is")
3. distinguish cardinal numbers (1st, 2nd, 5th - remake "into the first, second, fifth")
4. spelling - (US - remake into "u es")
and similar functionality?

Answer 1

write your own parser, as an option to make a map-based dictionary, for example, read line by line and analyze text, etc.
