Abstract
A current bottleneck In the automation of software Is the lack of available, standardized, reliable and valid methods for extracting knowledge from expert programmers. This paper discusses the development of Computer Aided Protocol (CAP) to automatically collect the general and specific cognitive task components of a programmer. Results Indicate that CAP was able to collect lower level goals while protocol analysis collected only 56 percent of these lower level goals. However, protocol analysis was able to obtain significantly more procedural knowledge relating to cognitive states of the subject and more high level goals than CAP (F(1,8)=11.23; p<.004). This work suggests that the integration of the information derived from both protocol and CAP for knowledge extraction would provide more effective information for the development of expert systems than is feasible with either system alone.
