Multiword expressions in multilingual applications within the Grammatical Framework

The main focus of Grammatical Framework (GF) is in multilingual applications
where the same type of content is produced and analyzed in several languages at
once. This is achieved by joining the grammars for all languages with a shared
interlingual representation. In designing the interlingua, multiword expressions
are an important factor that must be considered. Here, I adopt the broader defi-
nition where everything that translates non-compositionally accross languages is
considered an expression. In this chapter I present multiword expressions from a
cross-lingual perspective in relation to an interlingual grammar.
