Webtoday: CKY algorithm • Cocke-Kasami-Younger (independently discovered, also known as CYK) • a bottom-up parser for CFGs (and PCFGs) 13 “I shot an elephant in my pajamas. How he got into my pajamas, I'll never know.” — Groucho Marx CKY is a dynamic programming algorithm. Where else have we seen such an algorithm? 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-up parsing and dynamic programming. The standard version of CYK operates only on context-free grammars given in Chomsky normal …
