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…

Expressing Mathematical Subroutines Constructively
Roylance, Gerald

Formato:
Enlaces:	The typical subroutines that compute $\\sin(x)$ and $\\exp(x)$ bear little resemblance to our mathematical knowledge of these functions: they are composed of concrete arithmetic expressions that include many mysterious numerical constants. Instead of programming these subroutines conventionally, we can express…
