WebMar 7, 2024 · A natural language parser is a program that figures out which group of words go together (as “phrases”) and which words are the subject or object of a verb. The NLP parser separates a series of text into smaller pieces based on the grammar rules. If a sentence that cannot be parsed may have grammatical errors. 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 …
