... compares a number of statistical and machine learning techniques for ordering se- quences of adjectives in the context of a natural language generation system. 1 The problem The question of robustness ... for ordering adjectives is that it requires storing all of the adjective pairs observed in the training data. In this respect, the direct evidence method can be thought...
