WebJun 14, 2024 · Context-free grammars are part of the Chomsky hierarchy of languages which contains (in order of increasing expressiveness) regular, context-free, context-sensitive, and recursively enumerable grammars. Each differs in the family of production rules that are permitted and the complexity of the associated parsing algorithms (table 1).
WebCKY Algorithm Below is a probabilistic CFG and a 5-word sentence. Fill in the CKY table using the provided PCFG. Each cell should contain any matching non-terminals, and each non-terminal must have the probability of that non-terminal’s subtree.
