TRANSFOR- MATION The parsing algorithm of Vijay.Shanker and Joshi uses a special CKY algorithm for CFGs which requires fewer restrictive constraints than the Chomsky normal form for the ... Therefore, first the two form is defined and the idea of the constructive proof for transforming a TAG into two form is given. The TAG parser is then presented in more detail. 286 3.1 TWO FORM...
