SUMMARY:Multiword Expressions and Compositionality Detection: Giving Word 
 Embeddings a Hard Time - Aline Villavicencio (Federal University of Rio Gr

DESCRIPTION:In this talk I start with an overview of Multiword Expressions
  (MWEs) like compound nouns and verb particle constructions\, which have p
 roved a challenge for computational analysis. These expressions need to be
  treated as a unit at some level of linguistic description. In particular\
 , they display a wide range of compositionality\, from more compositional 
 cases like police car to more idiomatic MWEs like kick the bucket. Models 
 for representing words and MWEs in semantic space\, and their ability to c
 apture compositionality/idiomaticity will be compared for three languages:
  English\, French and Portuguese. The impact of some factors like the degr
 ee of corpus pre-processing and the size of context for the performance of
  these models will be discussed. I discuss the findings of a large-scale m
 ultilingual evaluation of DSMs for predicting the degree of semantic compo
 sitionality of nominal compounds on 4 datasets for English and French.
