Handbook for Evaluating Knowledge-Based Systems: Conceptual Framework & Compendium of Methods Cover

 

Synopses & Reviews

Publisher Comments:

Knowledge-based systems are increasingly found in a wide variety of settings and this handbook has been written to meet a specific need in their widening use. While there have been many successful applications of knowledge-based systems, some applications have failed because they never received the corrective feedback that evaluation provides for keeping development focused on the users' needs in their actual working environment. This handbook provides a conceptual framework and compendium of methods for performing evaluations of knowledge-based systems during their development. Its focus is on the users' and subject matter experts' evaluation of the usefulness of the system, and not on the developers' testing of the adequacy of the programming code. The handbook permits evaluators to systematically answer the following kinds of questions: Does the knowledge-based system meet the users' task requirements? Is the system easy to use? Is the knowledge base logically consistent? Does it meet the required level of expertise? Does the system improve performance? The authors have produced a handbook that will serve two audiences: a tool that can be used to create knowledge-based systems (practitioners, developers, and evaluators) and a framework that will stimulate more research in the area (academic researchers and students). To accomplish this, the handbook is built around a conceptual framework that integrates the different types of evaluations into the system of development process. The kinds of questions that can be answered, and the methods available for answering them, will change throughout the system development life cycle. And throughout this process, one needs to know what can be done, and what can't. It is this dichotomy that addresses needs in both the practitioner and academic research audiences.

Book News Annotation:

For practitioners and researchers increasingly reliant upon expert computer systems in a gamut of domains, this guide provides a conceptually-grounded tool for evaluating a knowledge-based system's efficacy in meeting task needs, user-friendliness, and ability to improve performance. Considerations include development models and five dimensions of evaluation models: requirements validation, knowledge-base verification, knowledge-base validation, usability evaluation, and performance evaluation. The concluding chapter by Adelman (George Mason U.) and Riedel (US Army Research Institute) is on planning and managing such evaluations. The appendix offers a generic questionnaire for assessing the utility of a decision-aiding system, and a survey tailored to a specific system (MapInfo).
