.... Tallis et al. developed a library of scripts for modifying knowledge bases, which helped to enforce the consistency of the modified knowledge [7, 27, 28, 29] Kim and Gil considered the use of scripts for building new knowledge acquisition tools, and created a system for evaluating these tools [9, 10]. Blythe et al. designed a general knowledge acquisition interface based on previous techniques [2] Musen developed the prot eg e environment for creating knowledge acquisition tools [14, 16] which proved e#ective for the development of knowledge systems, including the aids expert systems [20] ....

....in the future. While these approaches work well for simple tasks, as the complexity of the knowledge to be captured increases, direct knowledge authoring tools seem more useful. In the past we have built various knowledge editors and tools to enable end users to specify new knowledge directly [2,12,3]. Recently, we have been investigating approaches to helping end users author and analyze process models and plans, including process models in biology and plans in military applications. Often process models are quite complex, as shown in Figure 1. The figure illustrates a part of a process model ....

....Models to acquire procedural knowledge A theme of our KA research has been how KA tools can exploit Interdependency Models (Swartout Gil 1995) that relate individual componentsof the knowledge base in order to develop expectations of what users need to add next. EMeD (EXPECT Method Developer) (Kim Gil 1999; 2000), a knowledge acquisition tool to acquire problemsolving knowledge, exploits the Interdependency Models to guide users by helping them understand the relationships among the individual elements in the knowledge base. Our hypothesis is that Interdependency Models allow users to enter more knowledge ....

.... officers using our KA tools to extend a Course of Action critiquer, and was part of the Knowledge Acquisition Critical Component Experiment that was conducted as part of the DARPA High Performance Knowledge Bases program (Cohen et al. 1998) More details on these and other studies acn be found in (Kim Gil 2000; 2000; Blythe Gil 2000; Tallis Gil, 1999) With EMeD, we spent 8 hours (two half day sessions) for training. Users spent roughly half of that time learning EXPECT s language and how to put the procedural knowledge together. The rest of the time was spent learning about the KA tool and its ablated ....

....different types of users interact with it, so that we can improve our tools and our experimental methodology. For these reasons, we performed a preliminary study before the actual evaluation with domain experts. The study used a spectrum of users that had gradually less background in AI and CS (Kim Gil2000). We had (1) four knowledge engineers who had not used EMeD before but were familiar with EXPECT, 2) two knowledge engineers not familiar with EXPECT but that had experience with knowledge based systems, 3) four users not familiar with AI but had formal training in computer science, and (4) two ....

....the users was done with simpler sample tasks from the same knowledge base. The training time was significantly longer and harder for the subjects with no technical background (2 hours for knowledge engineers and 7. 5 hours for the project assis tants) More details of this study are discussed in (Kim Gil 2000), showing that even the end users were able to finish complex tasks, and that the KA tool saves more time as users have less technical background. As described above, we extended our tool based on the pre test results, creating a new version of EMeD (version 2) The next section describes the ....
