....including the FIBOF ESPRIT IV project which is presented here. Introduction Establishing effective communication among the different participants of an Information System Development project, and especially among users and developers, has been recognized as a crucial issue of software production [1], 2] 3] Users and developers have different knowledge and objectives and each community has its own vocabulary. Especially in large projects, these obstacles can be serious enough to put the project to failure. The classical approach to this problem consists in trying to make at least one ....

....a single strategy won t be much help. Additionally, if the user changes his mind about which problem solving stra tegy is appropriate, he may also have to change tools, potentially losing a lot of work in re configuring the domain knowledge. Recent knowledge acquisition work [Klinker et al. 1991; Musen and Tu 1993] has partially addressed these problems by creating tools that can use multiple problem solving methods. In PROTG II [Musen and Tu, 1993] problem solving methods are composed of preencoded building blocks. PROTG II permits modifications to problem solving by substituting one building block for ....

....this has been more flexible acquisition tools that allow users to make a greater variety of changes to the knowledge based system being built. To make this more concrete, we will begin by briefly reviewing three well known acquisition systems: TEIREISIAS [Davis 1976] SALT [Marcus 1988] PROTG II [Musen and Tu 1993]. We will then describe EXPECT, the acquisition framework we have been developing [Swartout and Gil 1995, Gil 1994, Gil and Paris 1994] Each of these four systems represents a point along the trend we outlined above. We conclude with a discussion about how these systems make the knowledge ....

....contain a library of problem solving methods of smaller size. New applications are built by composing the overall problem solving strategy from the smaller components of the library. Examples of systems that take this approach are SBF [Klinker et al. 1991] COMET [Steels 1990] and PROTG II [Musen and Tu 1993]. PROTG II guides acquisition based on fine grained role limiting methods. To build an application, a knowledge engineer configures the overall problem solving method using the components in the method library. At the same time, he or she builds a method ontology that contains the terms that are ....

....of implemented problem solving methods that can contribute program code to a system under development. Problem solving methods provide an enormous degree of procedural abstraction, allowing developers to treat complex algorithms as black boxes. Architectures such as those provided by Protg [40] and KSM [41] allow developers to compose problemsolving methods so that aggregations of methods can solve particularly complex tasks. The interactions among these problem solving methods can be reminiscent of the communication that takes among agents in agent oriented systems [42] Autonomous ....

Many of the medical knowledgebases built over the first 10 years of Protg shared a large percentage of their domain structural concepts (the second type of information in table 2) Most medical knowledge bases, whether they be for use within EON (Musen et al., 1995) or RESUME (Shahar and Musen, 1993) or some other knowledge based medical system, share notions such as patient, disease, and drug. 6.1.
