This chapter describes the development of the ideas behind the translator’s workstation, and looks at some of the computer-based tools that can be made easily available to translators. The translation activities discussed in this chapter can be broadly classified as computer-Aided Translation, though often a finer distinction is made between Machine-Aided Human translation and Human-Aided Machine Translation. This terminology suggests a spectrum of modes of operation in which the computer plays a progressively bigger part, which dictates the order of presentation of topics in this chapter.
