This book was released on 2012-12-06 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: What follows is a sampler of work in knowledge acquisition. It comprises three technical papers and six guest editorials. The technical papers give an in-depth look at some of the important issues and current approaches in knowledge acquisition. The editorials were pro duced by authors who were basically invited to sound off. I've tried to group and order the contributions somewhat coherently. The following annotations emphasize the connections among the separate pieces. Buchanan's editorial starts on the theme of "Can machine learning offer anything to expert systems?" He emphasizes the practical goals of knowledge acquisition and the challenge of aiming for them. Lenat's editorial briefly describes experience in the development of CYC that straddles both fields. He outlines a two-phase development that relies on an engineering approach early on and aims for a crossover to more automated techniques as the size of the knowledge base increases. Bareiss, Porter, and Murray give the first technical paper. It comes from a laboratory of machine learning researchers who have taken an interest in supporting the development of knowledge bases, with an emphasis on how development changes with the growth of the knowledge base. The paper describes two systems. The first, Protos, adjusts the training it expects and the assistance it provides as its knowledge grows. The second, KI, is a system that helps integrate knowledge into an already very large knowledge base.

Download or read book Knowledge Acquisition for Expert Systems written by A. Kidd and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: Building an expert system involves eliciting, analyzing, and interpreting the knowledge that a human expert uses when solving problems. Expe rience has shown that this process of "knowledge acquisition" is both difficult and time consuming and is often a major bottleneck in the production of expert systems. Unfortunately, an adequate theoretical basis for knowledge acquisition has not yet been established. This re quires a classification of knowledge domains and problem-solving tasks and an improved understanding of the relationship between knowledge structures in human and machine. In the meantime, expert system builders need access to information about the techniques currently being employed and their effectiveness in different applications. The aim of this book, therefore, is to draw on the experience of AI scientists, cognitive psychologists, and knowledge engineers in discussing particular acquisition techniques and providing practical advice on their application. Each chapter provides a detailed description of a particular technique or methodology applied within a selected task domain. The relative strengths and weaknesses of the tech nique are summarized at the end of each chapter with some suggested guidelines for its use. We hope that this book will not only serve as a practical handbook for expert system builders, but also be of interest to AI and cognitive scientists who are seeking to develop a theory of knowledge acquisition for expert systems.

Available in PDF, EPUB and Kindle. Book excerpt: This volume constitutes the proceedings of the 7th European Knowledge Acquisition Workshop (EKAW `93), held in Toulouse and Caylus, France, in September 1993. Traditionally the EKAW workshops deal with the various aspects of knowledge acquisition as a crucial topic in artificial intelligence as well as in computer science, engineering in general, and cognitive science. EKAW `93 had ist emphasis on knowledge acquisition for knowledge-based systems; besides the scientific workshop on the inter- disciplinary topic of knowledge acquisition there also was offered an open day as a users' forum open to the public. This proceedings contains the best papers presented at the scientific workshop after they had been selected by an international program committee consisting of leading experts in the field. The volume includes two surveys by Guy Boy and Brian Gaines and is divided in two main parts: the first part on problem solving models has sections on building steps, support tools, and comparison of approaches; the second part on life cycle and methodologies is divided in sections on refinement, methodologies, workbenches, and elicitation techniques.

Download or read book Current Trends in Knowledge Acquisition written by Bob Wielinga and published by IOS Press. This book was released on 1990 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge acquisition has become a major area of artificial intelligence and cognitive science research. The papers in this book show that the area of knowledge acquisition for knowledge-based systems is still a diverse field in which a large number of research topics are being addressed. However, several main themes run through the papers. First, the issues of integrating knowledge from different sources and K.A. tools is a salient topic in many papers. A second major topic in the papers is that of knowledge modelling. Research in knowledge-based systems emphasises the use of generic models of reasoning and its underlying knowledge. An important trend in the area of knowledge modelling aims at the formalisation of knowledge models. Where the field of knowledge acquisition was without tools and techniques years ago, now there is a rapidly growing body of techniques and tools. Apart from the integrated workbenches already mentioned above, several papers in this book present new tools. Although knowledge acquisition and machine learning have been considered as separate subfields of AI, there is a tendency for the two fields to come together. This publication combines machine learning techniques with more conventional knowledge elicitation techniques. A framework is presented in which reasoning, problem solving and learning together form a knowledge intensive system that can acquire knowledge from its own experience.

Download or read book Knowledge Acquisition written by James F. Brulé and published by McGraw-Hill Companies. This book was released on 1989 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important practitioner's guide is among the first to formulate a theoretical basis and derive a set of methods for consultants, knowledge engineers, and application programmers who must acquire human expert knowledge to create expert systems. By taking a cybernetic approach to the problems of knowledge acquisition, the authors use a single descriptive vocabulary to deal equally with recursive phenomena, knowledge acquisition, knowledge elicitation, expert system development, and the experts domain/knowledge base descriptions. Following a brief overview of the field, the authors focus on heuristic algorithms, the details of setting up a framework to define a given expertise, the practical interviewing process by which human experts pass on their knowledge to be modeled and coded for use in an expert system. The book concludes with a comprehensive case study selected for its broad application to all areas of knowledge acquisition.
