Online Learning of Relaxed CCG Grammars for Parsing to Logical Form Luke S. Zettlemoyer and Michael Collins MIT CSAIL lsz@csail.mit.edu,mcollins@csail.mit.edu Abstract We consider the problem of learning to parse sentences to lambda-calculus representations of their underlying semantics and present an algorithm that learns a weighted combinatory categorial grammar (CCG). A key idea is to introduce non-standard CCG combinators that relax certain parts of the grammar—for example allowing flexible
