I'm not quite sure exactly I was searching for, but somehow I serendipitously stumbled upon the site learnprolognow.org a few months ago. It's the home for an introductory Prolog programming course. Logic programming offers an interesting way to think about your problems; I've been doing so much procedural and object-oriented programming in the past decade that it really took effort to think at a higher level! I found the most interesting features to be definite clause grammars (DCG), and unification. Difference lists are very powerful and Prolog's DCG syntax makes it easy to work with them. Specifying a grammar such as: s(s(NP,VP)) --> np(NP,X,Y,subject), vp(VP,X,Y). np(np(DET,NBAR,PP),X,Y,_) --> det(DET,X), nbar(NBAR,X,Y), pp(PP). np(np(DET,NBAR),X,Y,_) --> det(DET,X), nbar(NBAR,X,Y). np(np(PRO),X,Y,Z) --> pro(PRO,X,Y,Z). vp(vp(V),X,Y) --> v(V,X,Y). vp(vp(V,NP),X,Y) --> v(V,X,Y), np(NP,_,_,object). nbar(nbar(JP),X,3) --> jp(JP,X). pp(pp(PREP,N
