WebGrammar Rules. Example 1 Example 2 WebCYK Algorithm is a membership algorithm of context free grammar. It is used to decide whether a given string belongs to the language of grammar or not. It is also known as CKY Algorithm or Cocke-Younger-Kasami …
In computer science, the Cocke–Younger–Kasami algorithm (alternatively called CYK, or CKY) is a parsing algorithm for context-free grammars published by Itiroo Sakai in 1961. The algorithm is named after some of its rediscoverers: John Cocke, Daniel Younger, Tadao Kasami, and Jacob T. Schwartz. It employs bottom … See more The dynamic programming algorithm requires the context-free grammar to be rendered into Chomsky normal form (CNF), because it tests for possibilities to split the current sequence into two smaller sequences.

This takes a sentence and a context-free grammar and determines whether there is a valid parse tree that can explain the sentence in terms of the production rules of the CFG. However, the CYK algorithm assumes that the context free grammar is in Chomsky Normal Form …
WebGet Free Course. The CYK algorithm is a parsing algorithm for context-free grammar. It is used to check if a particular string can be derived from the language generated by a given grammar. It is also called the membership algorithm as it tells whether the given string is a member of the given grammar or not.
