Hello! I recently graduated from BSUIR (Belarus) and now considering using prolog in my master thesis next year.
Unfortunately, there aren’t much decent online resourses to learn about prolog. I flipped through http://learnprolognow.org, but it’s merely an introduction. There were some advanced topics on http://edu.swi-prolog.org, but for some reason platform has been closed.
Can you, please, suggest some other learning resources? Are there any decent MOOCs?
If you’re using Prolog for knowledge representation, there are some books by John Sowa. Also: http://www.jfsowa.com/
There’s also Datalog and Datalog-like systems, if you’re interested in accessing structured data using a language better than SQL. Also, Yedalog (not sure of its status).
