On the Development of Commercial Expert Systems
We use our experience with the Dipmeter Advisor system for well-log interpretation as a case study to examine the development of commercial expert system. We discuss the nature of these systems as we see them in the coming decade, characteristics of the evolution process, development methods, and skills required in the development team. We argue that the tools and ideas of rapid prototyping and successive refinement accelerate the development process. We note that different types of people are required at different stages of expert system development: Those who are primarily knowledgeable in the domain, but who can use the framework to expand the domain knowledge; and those who can actually design and build expert systems. Finally, we discuss the problem of technology transfer and compare our experience with some of the traditional wisdom of expert system development.

Report on the 1984 Distributed Artificial Intelligence Workshop
The fifth Distributed Artificial Intclligencc Workshop tias held at the Schlumberger-Doll Research Laboratory from October 14 to 17, 1984 It was attended by 20 participants from academic and industrial institutions. As in the past,’ this workshop was designed as an informal meeting It included brief research rcport,s from individual groups along with genera1 discussion of questions of common interest. This report summarizes the general discussion and contains summaries of group presentations that have been contributed by individual speakers to scale the resources applied to a problem). Others arc motivated by problem characteristics, such as natural spatial or functional distribution. Finally, some researchers are motivated by the observation that some issues in problcm solving and reasoning (e.g., communication and coherent cooperation) are brought into sharp focus in the distributed setting. The main body of this report contains summaries written by individual attcndces of the workshop. This is, in turn, followed by a brief smnmary of the gcncral discus

A Conceptual Clustering Program for Rule Generation
We present an Interesting Situation Generator (ISG) that assists in the synthesis of interpretation rules from basic domain knowledge. The ISG is a hierarchical clustering program that discovers equivalence classes of situations (e.g. types of geological formations) that give rise to qualitatively distinct manifestations (e.g. different patterns of geophysical measurements corresponding to types of geological formations). The equivalence classes can be used by a rule generator to construct an initial set of interpretation rules of the form manifestation ⇒ situation.

Automated auditing of design principle adherence
Software design patterns and refactoring browsers are useful tools in developing high-quality software. Object-Oriented Oracle (OOO) is a tool that combines patterns and refactoring and extends them with the ability to recognize when the source-base doesn't adhere to software design principles. OOO relies on sophisticated compiler analyses and a set of heuristics to recognize characteristics of the code where a design principle is applicable, but is not being used. We present an example where the OOO can recognize noncompliance of design rules and the analyses and heuristics that are used to do the recognition. We also discuss other patterns where this approach applies and results from a prototype.

A Framework to place Cross-cultural Case Study Research in an Information Systems Action Research Context
2 School of Management Information Systems, Deakin University, Australia. E-mail: smithr@deakin.edu.au . ABSTRACT: The progressive evolution of the global information society has escalated the debate over effective ways to facilitate relevance in information systems research without sacrificing rigor. Accommodation of interpretivist research methodologies has been suggested to address this problem, particularly in instances of research conducted in Asian developing countries. This paper discusses problems encountered in attempting to apply, in such a context, positivist longitudinal case study research methods, using models originating from research focused on organisations in Western, developed economies. We outline a synthesis of the positivist methods with an action research approach, and the subsequent use of a particular research framework to track progress and report outcomes.

Undergraduate Software Engineering - An Innovative Degree at Swinburne
In this paper we outline the context for the development of an undergraduate degree in Software Engineering in Australia, reflect on curriculum development ideas relevant to such a degree, and describe aspects of the Computer Science degree at Swinburne which, despite its title, may be viewed as a Software Engineering degree. We emphasise the role of project-based units within the degree.

The Fighter Aircraft LCS: A Case of Different LCS Goals and Techniques
A system employed by the authors to acquire novel fighter aircraft manoeuvres from combat simulation is more akin to the traditional LCS model than to more recent systems. Given the difficulties often experienced in LCS research on simple problems, one must ask how a relatively primitive LCS has had consistent success in the complex domain of fighter aircraft manoeuvring. This paper presents the fighter aircraft LCS, in greater detail than in previous publications. Positive results from the system are discussed. The paper then focuses on the primary reasons the fighter aircraft LCS has avoided the difficulties of the traditional LCS. The authors believe the system's success has three primary origins: differences in credit assignment, differences in action encoding, and (possibly most importantly) a difference in system goals. In the fighter aircraft system, the goal has been simply the discovery of innovative, novel tactics, rather than online control. The paper concludes by discussing the most salient features of the fighter aircraft learning system, and how those features may be profitably combined with other LCS developments.
