Compositionnaliteé en sémantique distributionnelle et ordonnancement des adjectifs

In this talk, we propose an unsupervised approach to determine restrictions in adjective ordering through the use of compositional methods in distributional semantics. Specifically, we focus on being able to automatically distinguish phrases in which there is flexibility in the adjective ordering from those bound to a rigid order. We explore a number of measures extracted from the distributional representation of a phrase, both qualitative and quantitative, which may indicate a word order restriction. We find that we are able to distinguish the two cases of ordering significantly based primarily on the degree of modification of the adjectives. Currently, this approach has only been implemented in English, yet we predict that the methodology and results pertain naturally to French. This method offers fresh insight into the semantic properties that determine adjective ordering, building a bridge between syntax and distributional semantics.
