Table 1 summarizes the properties just explained. Our goal is to use these properties to induce the semantic class of adjectives. For instance, if an adjective is denominal, appears almost exclusively in postnominal position, and is strictly adjacent to the head noun, we predict that it is relational. In the experiments reported in Sections 4 and 5, we extract data related to these and other properties of adjectives from linguistic resources, and use them as features in machine learning experiments.
