I'm dealing with a "ticket similarity task".
Every time new tickets arrive at the help desk (customer service), I need to compare them and find out about similar ones.
In this way, once the operator responds to a ticket, at the same time he can solve the others similar to the one solved.
I expect an input ticket and all the other tickets with their similarity in output.
I thought about using DOC2VEC, but it requires training every time a new ticket enters ...
what do you recommend?
