A Lexical Conceptual Approach to Generation for Machine Translation
Dorr, Bonnie J.

Formato:
Enlaces:	Current approaches to generation for machine translation make use of direct-replacement templates, large grammars, and knowledge-based inferencing techniques. Not only are rules language-specific, but they are too simplistic to handle sentences that exhibit more complex phenomena. Furthermore, these systems are…
