  5. 5. Language Research Areas School of Computer Applications Example Based Machine Translation Given : John went to school Jean est allé à l’école . The butcher’s is next to the baker’s La boucherie est à côté de la boulangerie. Isolate useful fragments: John went to Jean est allé à the baker’s la boulangerie We can now translate: John went to the baker’s as Jean est allé à la boulangerie .
