This report presents an analysis of an expert performing a highly interactive computer task. The analysis uses GOMS models, specifying the Goals, Operators, Methods, and Selection rules used by the expert; the GOMS models are implemented within a unified theory of cognition called Soar. Two models are presented, one with function-level operators, performing high-level functions in the domain; and one with keystroke-level operators, describing hand movements. For a segment of behavior in which the expert accomplished about 30 functions in a computer game in about 30 seconds, the function-level model predicted the observed behavior well, while the keystroke-level model predicted only about half of the observed hand movements. These results, including the discrepancy between the models, are discussed. Appendices include a transcription of observed behavior, predictions of the GOMS models, and a comparison between observed expert behavior and predictions of the GOMS models.

The rapid growth of the need for technical translations in recent years has led specialists to utilize computer technology to improve the efficiency and quality of translation. The two approaches considered were automatic translation and terminology banks. Since the results of fully automatic translation were considered unsatisfactory by various reports, significant efforts were made to construct automatized terminology banks. A critical comparison of the main existing banks suggests that these banks are the first step toward interactive translation systems. Exchange problems in networks of banks and terminological cooperation between international organizations will necessitate standardization of terms, symbols, and definitions. It is proposed that automatized terminology banks be designed from a different viewpoint by making greater use of well known techniques in computer systems and artificial intelligence, based on evaluation of present and future developmental issues in data base organization, translation research, interactive translation systems, and man-computer communication.
