Skillex: A graph-based lexical score for measuring the semantic efficiency of used verbs by human subjects describing actions

Dictionaries are sociocultural objects that can be used as underlying structures of cognitive science models. We first show that the lexical networks constructed from dictionaries, despite a surface disagreement at links level, share a common topological structure. We assume that this deep structure reflects the semantic organisation of the lexicon shared by the members of a linguistic community. We propose a model based on the exploration of this specific struc- ture to analyse and compare the semantic efficiency of [Children/Adults] productions in action labelling tasks. We define a generic score of semantic efficiency, S KILLEX. Assigned to partic- ipants of the A PPROX protocol, this score enables us to accurately classify them into Children and Adults categories.
