The meaning of what I’d like to say is: “The research of this year”.
Do I make mistakes if I say “This year research” or “This year’s research”?
Hi Marilena,
You can say ‘This year’s research’, but not "This year research’ to indicate what you mean.
If you say ‘This year, research.’ it becomes an imperative, a command to somebody to do research all year long. 
Oh! thank you
So I am wrong also if I say “local community collaboration” instead of “local community’s collaboration”, when what I mean is “the collaboration of the local communities”, right? Where can I find the grammatical rule of this, to clarify in my mind the subject?
