Description

The SemETAP semantic model is a part of a more general ETAP linguistic processor aiming at analyzing and generating NL texts. The task of SemETAP is building two kinds of semantic structures – Basic SemS, which capture the core meaning of the sentence, and Enhanced SemS, which contain diverse inferences drawn from Basic SemS. SemETAP is supported by two main lexical resources – a combinatory dictionary of Russian and an ontology. One important requirement for the SemS is that it should explicitly represent all semantic arguments of the predicates of the sentence, expressed by all kinds of words – verbs, nouns, adjectives or adverbs. We discuss the argument structure of ordinal adjectives (first, second,…, last, next), which has been largely neglected in the literature on valency and arguments. Several semantic slots are introduced for ordinal adjectives: hasObject, hasObject2, belongsTo, hasNumber, hasStartingPoint, hasTerminalPoint, orderedBy. Our analysis reveals interesting features in the behavior of the arguments of ordinal adjectives.
