I’m not sure of the numbers, but I had in mind all of that ground-breaking work by Chris Collins, Luke Zettlemoyer, Mark Steedman, Percy Liang, Siva Reddy, Miralla Lapata, Jayant Krishnamurthy, and lots of others. Percy and I tried to provide a guide to this stuff in our paper Bringing machine learning and compositional semantics together. (I guess that title explains why I was primed to think of this example!)
