By convention, the lefthand side of the first production is the start-symbol of the grammar, typically S, and all well-formed trees must have this symbol as their root label. In NLTK, context-free grammars are defined in the nltk.grammar module. WebbCHOMSKY NORMAL FORM. Context-free grammars come in a wide variety of forms.
