... likely structure and la- beling. This is similar to conventional probabilis- tic context-free grammar (PCFG) parsing, with two exceptions: (a) we maximize conditional likelihood of the parse tree, ... infinite unary chains with infinite mass. However, it is standard in the parsing liter- ature to transform grammars into a restricted class of CFGs so as to permit efficient parsing. Bina...
