Identification of Multiword Expressions: comparing the performance of a Conditional Random Fields model on corpora of written and spoken Italian

This paper describes an experiment that compares the performance of a Conditional Random Fields model on identification of Multiword expressions in corpora of spoken and written Italian. The model is trained on a corpus of spoken language and a corpus of written language annotated with Multiword expressions, then tested on two other corpora (one written and one spoken). This methodology provides very good results regarding Precision.
