Distributional Measures of Semantic Abstraction.

ABSTRACT: This article provides an in-depth study of distributional measures for distinguishing between degrees of semantic abstraction. Abstraction is considered a "central construct in cognitive science" (Barsalou, 2003) and a "process of information reduction that allows for efficient storage and retrieval of central knowledge" (Burgoon et al., 2013). Relying on the distributional hypothesis, computational studies have successfully exploited measures of contextual co-occurrence and neighbourhood density to distinguish between conceptual semantic categorisations. So far, these studies have modeled semantic abstraction across lexical-semantic tasks such as ambiguity; diachronic meaning changes; abstractness vs. concreteness; and hypernymy. Yet, the distributional approaches target different
