WebDerivation. Derivation is a sequence of production rules. It is used to get the input string through these production rules. During parsing, we have to take two decisions. These are as follows: We have to decide the non-terminal which is to be replaced. We have to decide the production rule by which the non-terminal will be replaced.

Every non-terminal in a CFG stands for a language. Thinking in terms of languages instead of strings should be more helpful sometimes for constructing the CFG. WebA CFG is said to be in Chomsky Normal Form if every production is of one of these two forms: 1. A -> BC (right side is two variables). 2. A -> a (right side is a single terminal).
