Combining Linguistic Features for the Detection of Croatian Multiword Expressions
Maja Buljan, Jan Šnajder · 2017
As multiword expressions (MWEs) exhibit a range of idiosyncrasies, their automatic detection warrants the use of many different features.Tsvetkov and Wintner (2014) proposed a Bayesian network model that combines linguistically motivated features and also models their interactions.In this paper, we extend their model with new features and apply it to Croatian, a morphologically complex and a relatively free word order language, achieving a satisfactory performance of 0.823 F1-score.Furthermore, by comparing against (semi)naïve Bayes models, we demonstrate that manually modeling feature interactions is indeed important.We make our annotated dataset of Croatian MWEs freely available.
