The modelling of the semantics of adjectives is notoriously challenging. We consider this prob- lem in the context of the so called ontology-lexicon interface, which attempts to capture the semantics of words by reference to an ontology in description logics or some other, typically first-order, logical formalism. The use of first order logic (hence also description logics), while effective for nouns and verbs, breaks down in the case of adjectives. We argue that this is primar- ily due to a lack of logical expressivity in the underlying ontology languages. In particular, be- yond the straightforward intersective adjectives, there exist gradable adjectives, requiring fuzzy or non-monotonic semantics, as well as operator adjectives, requiring second-order logic for modelling. We consider ho...
