Abstract

GRADE, a software environment for machine translation is described. It has been developed for the Mu machine translation project, which was supported by the Science & Technology Agency of the Japanese Government. GRADE consists of 3 components: (1) a grammar writing language based on flexible tree-to-tree transformation rules with a control mechanism and an interpreter; (2) software tools for constructing and maintaining grammar rules; and (3) software tools for developing dictionary databases which are based on the concept ofneutral dictionary. In this paper, these software packages are discussed from the viewpoint of the development of a large scale machine translation system.
