Using DLL is an excellent way to reuse code. You don't have to re-implement the same routine in every program you create, but you just need to write these routines once and then refer

there is no sample code available. It is also unfortunate that machine learning lacks a framework or gem based on Ruby. Discover Python and NLTK I continued to search the solution and encountered "Python" in the result set. As a Ruby developer, although I haven't learned the language yet, I know that Python is a text-based, understandable, and dynamic programming language for similar objects. Although there are some similarities between the two lan
