Designing scripts to guide users in modifying knowledge-based systems
Marcelo Tallis, Yolanda Gil · 1999
Knowledge Acquisition #KA# Scripts capture typical modi#cation sequences that users follow when they modify knowledge bases. KA tools can use these Scripts to guide users in making these modi #cations, ensuring that they follow all the rami- #cations of the change until it is completed. This paper describes our approach to design, develop, and organize a library of KA Scripts. We report the results of three di#erent analysis to develop this library, including a detailed study of actual modi#cation scenarios in two knowledge bases. In addition to identifying a good number of KA Scripts, we found a set of useful attributes to describe and organize the KA Scripts. These attributes allow us to analyze the size of the library and generate new KA Scripts in a systematic way. Wehave implemented a portion of this library and conducted two di#erent studies to evaluate it. The result of this evaluation showeda15to52percent time savings in modifying knowledge bases and that th...
