WebYou are allowed to use NLTK and Stanford's NLP packages supporting PCFG parsing so that you don't have to code up the classes and data structures needed to maintain the grammar. But the rest of the programming must be done from scratch (e.g., the binarization and the CKY dynamic programming algorithm). Binarization WebVery important in NLP (and beyond) We will start with the non-probabilistic version 5. Constraints on the grammar The basic CKY algorithm supports only rules in the Chomsky Normal Form (CNF): Unary preterminal rules (generation of words given …
