... open question whether there exist important statistical dependencies that go beyond linguistically motivated dependencies. The Data Oriented Parsing (DOP) model, on the other hand, takes a rather extreme ... there may be several distinct derivations that generate the same parse tree. The probability of a parse tree T is thus the sum of the probabilities of its distinct derivatio...
