Aline Villavicencio visited the EMW Project Team at Koç University

Aline Villavicencio, one of the advisors of the Emerging Welfare Project, came to visit us at Koç University and gave a speech, titled Identifying Idiomatic Language with Distributional Semantic Models, on February 21, 2019. You can find the abstract below.


Precise natural language understanding requires adequate treatments both of single words and of larger units. However, expressions like compound nouns may display idiomaticity, and while a police car is a car used by the police, a loan shark is not a fish that can be borrowed. Therefore it is important to identify which expressions are idiomatic, and which are not, as the latter can be interpreted from a combination of the meanings of their component words while the former cannot. In this talk I discuss the ability of distributional semantic models (DSMs) to capture idiomaticity in compounds, by means of a large-scale multilingual evaluation of DSMs in French, Portuguese and English. The results obtained show a high correlation with human judgments about compound idiomaticity  (Spearman’s ρ=.82 in one dataset), indicating that these models are able to successfully detect idiomaticity.B
