From Guidon to Neomycin and Heracles in Twenty Short Lessons

AI Magazine

I review the research leading from the GUIDON rule-based tutoring system, including the reconfiguration of MYCIN into NEOMYCIN and NEOMYCIN's generalization in the heuristic classification shell, HERACLES. The presentation is organized chronologically around pictures and dialogues that represent conceptual turning points and crystallize the basic ideas. My purpose is to collect the important results in one place, so they can be easily grasped. In the conclusion, I make some observations about our research methodology.


Review of The Connection Machine

AI Magazine

Hillis's book, like its bibliography, has something to offer nearly everyone in the computer science community, even those with no background in computer architecture. The book provides a glimpse of what the next generation of computers will be like.


Research in Artificial Intelligence at the University of Pennsylvania

AI Magazine

This report describes recent and continuing research in artificial intelligence and related fields being conducted at the University of Pennsylvania. Although AI research takes place primarily in the Department of Computer and Information Science ( in School of Engineering and Applied Science), many aspects of this research are preformed in collaboration with other engineering departments as well as other schools at the University, such as the College of Arts and Sciences, the School of Medicine, and Wharton School.


Blackboard Application Systems, Blackboard Systems and a Knowledge Engineering Perspective

AI Magazine

The objectives of this document (a part of a retrospective monograph on the AGE Project currently in preparation) are (1) to define what is meant by blackboard systems and (2) to show the richness and diversity of blackboard system designs. In Part 1 we discussed the underlying concept behind all blackboard systems -- the blackboard model of problem solving. We also traced the history of ideas and designs of some application systems that helped shape the blackboard model. In application systems, the blackboard system components are integrated into the domain knowledge required to solve the problem at hand.


Strategy and Business Planning for Artificial Intelligence Companies: A Guide for Entrepreneurs

AI Magazine

This article provides some basic assistance to entrepreneurs involved in artificial intelligence, offering a synthesis of standard business-planning and capital-raising practices. Three main areas are discussed: (1) developing a corporate strategy, (2) developing a business plan that works, and (3) approaching sources of capital.


A Simple View of the Dempster-Shafer Theory of Evidence and Its Implication for the Rule of Combination

AI Magazine

During the past two years, the Dempster-Shafer theory of evidence has attracted considerable attention within the AI community as a promising method of dealing with uncertainty in expert systems. As presented in the literature, the theory is hard to master. In a simple approach that is outlined in this paper, the Dempster-Shafer theory is viewed in the context of relational databases as the application of familiar retrieval techniques to second-order relations in first normal form. The relational viewpoint clarifies some of the controversial issues in the Dempster-Shafer theory and facilities its use in AI-oriented applications.


Artificial Intelligence Research and Applications at the NASA Johnson Space Center: Part One

AI Magazine

Research and applications work in AI is being conducted by several groups at Johnson Space Center (JSC). In the Research and Engineering Directorate, these groups include (1) the Artificial Intelligence and Information Sciences Office, (2) the Simulation and Avionics Integration Division, (3) the Avionics Systems Division (ASD), and (4) the Tracking and Communications Division. In the Space Operations Directorate, these groups include (1) the Mission Planning and Analysis Division - Technology Development and Applications Branch, (2) the Spacecraft Software Division, and (3) the Systems Division-Systems Support Section. The first part of the article describes the AI work in Research and Engineering Directorate.


The Blackboard Model of Problem Solving and the Evolution of Blackboard Architectures

AI Magazine

The objectives of this article are (1) to define what is meant by "blackboard systems" and (2) to show the richness and diversity of blackboard system designs. The article begins with a discussion of the underlying concept behind all blackboard systems, the blackboard model of problem solving. In Section 2 the history of ideas is traced, and the designs of some application systems that helped shape the blackboard model are detailed. Part 2 of this article which will appear in the next issue of AI Magazine, describes and contrasts some blackboard systems and discusses the characteristics of application problems suitable for the blackboard method of problem solving.


A Knowledge System that Integrates Heterogeneous Software for a Design Application

AI Magazine

We have implemented a knowledge system that integrates the many computational programs ( technology codes) Boeing aerospace vehicle designers use, thereby expediting design analysis. Because this system separates facts about attributes of the current set of technology codes from general knowledge about running the codes, those who maintain the system can keep it continuously up to date at low cost. In contrast, three conventional approaches failed because they could not be maintained easily.


Recent and Current Artificial Intelligence Research in the Department of Computer Science SUNY at Buffalo

AI Magazine

This article contains reports from the various research groups in the SUNY Buffalo Department of Computer Science, Vision Group, and Graduate group in Cognitive Science. It is organized by the different research topics. However, it should be noted that the individual projects might also be organized around the methodologies and tools used in the research, and, of course, many of the projects fall under more than one category.
