This report treats some of the technical difficulties encountered in lexicological studies that were undertaken in order to establish a basic vocabulary. Its purpose is to show that the computer can overcome some of these difficulties, and specifically that computer programming can serve to establish a vocabulary common to scientific and technical languages. The discussion of the advantages of computer programming centers on the following topics: (1) availability, including a description of the compilation and correction of data, indexing, and programming; and (2) general vocabulary that is scientifically oriented, including a description of the process of choosing and identifying words, and the choice and structure of dictionaries.
