WebThe inside-outside algorithm is a recursive dynamic programming scoring algorithm that can follow expectation-maximization paradigms. It computes the total probability of all derivations that are consistent with a given sequence, based on some PCFG. WebCYK, known as Cocke-Kasami-Youngerknown, is one of the oldest parsing algorithms. The standard version of CKY recognizes only languages defined by context-free grammars in CNF. It is also possible to excel the CKY algorithm to handle some grammars which are harder to understand.
