This paper describes the design of a prototype machine translation system for a sublanguage of job advertis~nents. The design is based on the hypothesis that specialized linguistic subsystems may require special crmputational treatment and that therefore a relatively shallow analysis of the text may be sufficient for automatic translation of the sublanguage. This hypothesis and the desire to minimize computation in the transfer phase has led to the adoption of a flat tree representation of the linguistic data. . | DESIGN OF A MACHINE TRANSLATION SYSTEM FOR A SUBLANGUAGE Beat Buchmann Susan Warwick Patrick Shann Dalle Molle Institute for Semantic and Cognitive Studies University of Geneva Switzerland ABSTRACT This paper describes the design of a prototype machine translation system for a sublanguage of job advertisements.

INTRODUCTION The most premising results in computational linguistics and specifically in Machine Translation MT have been obtained where applications were limited to languages for special purposes and to restricted text types Kittredge Lehrberger 1982 . In light of these prospects the prototype MT system described below-L should be seen as an experiment in the computational treatment of a particular sublanguage. The project is meant to serve both as a didactic tool and as a vehicle for research in MT. The development of a large-scale operational system is not envisaged at present. The following research objectives have been defined for this project - to establish linguistic specifications of the sublanguage as a basis for automatic processing - to develop translation algorithms tailored to a computational treatment of the sublanguage. The emphasis of the research lies in defining the depth of linguistic analysis necessary to adequately treat the complexity of the text type with a view to acceptable machine translation. It is the conjecture of our research group that within the particular sublanguage defined by our corpus acceptable translation does not necessarily depend on standard linguistic structural analysis but can be obtained with a relatively shallow .
