Linguistic Documentation of Metal System

Abstract : The report constitutes a linguistic documentation of the third generation machine translation system designated METAL (Mechanical Translation and Analysis of Languages, or METALanguage). Section I presents an overview of the system (underlying philosophy and general description of system's components). It also includes a description of 14 programs (translation phases), used in the original FORTRAN implementation, and a description of the system's LISP version (8 translation phases). The remaining sections describe in detail each phase in the German-English machine translation process. The description for a phase gives examples of rules used at this stage, and annotates the features and possible feature values used by the program, as well as the operations that may be performed at hat point.
