| Abstract: | We describe a quantitative model for the performance evaluation of
interactive computer systems. The approach involves the development of
an "interaction graph" or state transition diagram to describe
the user-machine interaction. Given numerical data on transition times
and probabilities, the model can be used to perform sensitivity analyses
of changes in system parameters and user behavior. To illustrate the
model, we use empirical data from field and laboratory experiments
designed to compare a prototype natural language query system with a
formal (relational) query system. The general approach is applicable in
a broad range of other contexts including bibliographic retrieval and
the analysis of web-log data. It should be of interest to both system
developers and potential users of these systems. |
