Documentation

This class represents a bracted string used in training of SCFGs.

An object in this class builds an index of valid bracketing of the string. Thus offering both a tree like access and direct access to the leafs of the tree. The definition of ``valid bracketing'' is any substring

that doesn't cross any brackets.
