This is a cooperative project aimed at the development, evaluation and application of programs for alignment and data generation from parallel corpora with Swedish as either source or target language. Applications include machine translation, computer-aided translation, translation data bases, multi-lingual web dictionaries and translator's training. The participating departments are Swedish language, Göteborg university, Computer and information science, Linköping university, and Linguistics, Uppsala university.
