Bratko’s textbook contains a semantic parser for a very tiny fragment of English. It can parse sentences like every woman that admires a man that paints likes monet. into ∀x: woman(x) ∧ (∃y: man(y) ∧ paints(y) ∧ admires(x, y) → likes(x, monet)) which is fun (although incorrect, in this case). …

Well, surely not ‘state-of-the-art’, but I suggest to take a look at chat80 . For something playable and more advanced, I suggest to evaluate Attempto .

Yes, the pack is the way to go. Thanks for pointing out.

There was quite a bit of work on this in the 1980s and 1990s. Two projects I know of (that also used Prolog) were “Lilog” at IBM Germany (there’s a Springer book on that) and another at IBM Sweden, but I can’t find the references to the latter (it was based on someone’s PhD thesis, I think). I’ll tr…

A bit ashamed to ask… but what is incorrect in that sentence ?

[image] CapelliC: what is incorrect in that sentence “a man” is ambiguous and can mean “there exists”, as in, “A man is in my garage”, or “for any”, as in “A man needs regular sleep”. In this particular case, a universal quantifier makes more sense, but Bratko’s mini-grammar interprets “a” on…

Sorry I don’t have a copy of Bratko available, but probably the technique he applied should derive from the formalization (or better, implementation in Prolog) of Montague approach, popularized from Pereira Schieber in Prolog and Natural-Language Analysis (I have the Italian edition). In this book, …

There is also quite extensive study on semantic representation of natural language for the purpose of inferencing by Blackburn and Bos here ( folder with files ). (all examples are in Prolog).

[image] CapelliC: probably the technique he applied should derive from the formalization (or better, implementation in Prolog) of Montague approach, I am very glad to see this comment. In fact, I have a cgi page on Montague’s PTQ (sorry only in Japanese.) http://web.sfc.keio.ac.jp/~mukai/cgi…
