Satisficing in knowledge-based systems
Data & Knowledge Engineering, 1990Abstract A satisficing knowledge-based system reaches a satisfactory resolution as quickly as possible. A satisfactory resolution is one that reaches an answer that may not be optimal, but is satisfactory or heuristically “close enough”. This work focuses on the principles that can be used to support a methodology that will produce satisficing ...

Knowledge-based systems: an overview
IEEE Expert, 1991Research sponsored by the US Department of Defence's Defense Advanced Research Projects Agency (DARPA) under the Strategic Computing Initiative is reviewed. The program has emphasized technologies that would provide significant advances in four areas: scalability, real-time performance, reusability, and methodologies for integration.

On Knowledge-Based System Architectures
1986This chapter investigates architectural issues of Knowledge-Base Management Systems (KBMSs) that might result from the integration of Knowledge-Base (KB) systems and Database Management Systems (DBMS) technology. A hypothetical KBMS architecture is presented that assumes the decomposition and current KB systems and DBMSs into components that may ...

Cooperative Knowledge-Based Systems
Intelligent Automation & Soft Computing, 1996ABSTRACTTraditional query processing provides exact answers to queries. It usually requires that users fully understand the database structure and content to issue a query. Due to the complexity of database applications, incorrect or incompletely specified queries are frequently posed and the users often receive no answers or they might need more ...

Knowledge-Based Control Systems
2001The monitoring and control of devices and systems has attracted attention from the field of knowledge-based systems for a number of reasons. The problem is intrinsically knowledge-intensive, benefiting from awareness of the behaviour and interactions of components.

A framework for knowledge-based systems
Journal of Applied Non-Classical Logics, 1996The paper continues the theme of [ knowledge.ps ]. We differentiate between our approach to knowledge representation and that of others by expressing the following Working Hypothesis: Knowledge is a data type, and knowledge revision is accomplished by continuous operations on it, which are coordinated with its effective basis.

Knowledge acquisition for knowledge-based engineering systems
International Journal of Information Technology and Management, 2005This paper is essentially concerned with the development of formal representations of knowledge required prior to the development of knowledge-based engineering systems (KBESs). Initially, the paper provides a brief introduction to knowledge-based systems (KBSs) and KBESs, stating the key commonalities and differences between the two, and presents the ...

Transferability of Knowledge Based Systems
1991This presentation illucidates the impact information technology factors may have on transferability of knowledge based systems. The paper describes how database content, knowledge acquisition and knowledge representation may hamper or enhance viable transfer of knowledge based systems.

AN INFERENCE BROWSER FOR VERIFYING THE KNOWLEDGE BASE IN KNOWLEDGE-BASED SYSTEMS
International Journal on Artificial Intelligence Tools, 1993In developing knowledge-based systems, the process of collecting the knowledge from the experts, representing it in certain formats, and verifying it is required. It is however not easy to verify the formulated knowledge base by checking if a desired conclusion is derived by a sequence of inferring steps.

Multilevel security for knowledge based systems
[1990] Proceedings of the Sixth Annual Computer Security Applications Conference, 1990Work aimed at defining a multilevel, mandatory security policy for knowledge based systems. The authors address two distinct issues: an effective implementation formalism based on a multilevel, object oriented programming paradigm and requirements for ensuring the correctness of inferences computed on the basis of possibly contradictory information ...
