A dop model for phrase structure trees

This chapter gives an instantiation of DOP (Scha 1990, 1992; Bod 1992) which is known as Tree-DOP or DOP1 and which will be extensively used in the rest of this book. Tree-DOP combines subtrees from a treebank to parse new sentences. It employs the relative frequency estimator to assign probabilities to subtrees, and computes the probability of a parse tree as the sum of the probabilities of its derivations.
