Functional and Cognitive Aspects in Linguistic Modelling

The paper focuses on the issues of establishing transferable language phrase structures.

The formalism developed for presentation of syntactic structures for the English-Russian machine translation is a variant of unification grammar and comprises about three hundred rules. A number of declarative modules of linguistic processors were designed and implemented w i t h i n t h e f r a m e w o r k o f m a c h i n e t r a n s l a t i o n system“Cognitive Translator” and knowledge extraction systems.
