Knowledge-Based Intermediaries
International Journal of E-Business Research, 2008A new generation of intermediaries is predicted to flourish in the emerging electronic markets. They rely on new information technologies such as the semantic Web, rule-based triggers, and knowledge-based constraint maintenance systems. These technologies do not automate or reduce intermediation, but inspire new types of intermediaries that rely on the

Distributed Computing, 1995
Reasoning about activities in a distributed computer system at the level of the knowledge of individuals and groups allows us to abstract away from many concrete details of the system we are considering. In this paper, we make use of two notions introduced in our recent book to facilitate designing and reasoning about systems in terms of knowledge. The

KNOWLEDGE-BASED OR KNOWER-BASED?
The Singapore Economic Review, 2001This paper analyses the concept of a knowledge-based society. It suggests that certain important features of a knowledge-based society are better understood by appealing to the notion of a knower-based society, and discusses some implications following from this.

Collaboration of Knowledge Bases via Knowledge Based Coordination
1991To take advantage of the growing number of databases and knowledge bases, we present a system that allows for cooperation among spatially distributed agents. Cooperation is supported by providing a uniform agent model and a framework for instantiating various cooperation strategies.

Knowledge base views in multiuser knowledge based systems
Proceedings. Fourth International Conference on Data Engineering, 2003The author presents a methodology for representing knowledge in a collection of interlinked, largely autonomous knowledge base views, to facilitate multiple heterogeneous use of a KBS (knowledge based system). The knowledge base views are defined so that while knowledge outside each user's view is transparent to him/her, problem solving can be achieved

Research on Knowledge Model for Ontology-Based Knowledge Base
2011 International Conference on Business Computing and Global Informatization, 2011The robust knowledge base needs a reasonable design pattern to represent knowledge model. On the foundation of the research about relationship of knowledge model with knowledge ontology, the knowledge model defined by three categories of domain knowledge, reasoning knowledge and task knowledge is set up. Furthermore, the matching relationship mechanism

Knowledge Exploration in Medical Rule-Based Knowledge Bases
2017This paper introduces the methodology of domain knowledge exploration in so called rule-based knowledge bases from the medical perspective, but it could easily by transformed into any other domain. The article presents the description of the CluVis software with rules clustering and visualization implementation.

In the present work we introduce a simple yet powerful formalism to model the evolution of knowledge bases. The semantics are based on the fundamental intuition that more recent information overrides previous knowledge, insofar as keeping the old knowledge would lead to inconsistencies.

Review of Educational Research, 1993
"Toward a Knowledge Base for School Learning" (Wang, Haertel, & Walberg, 1993a) is an ambitious and provocative piece of work. It purports to capture the essential lessons from several broad domains of research and translate them into findings that are relevant for educational policy and practice.

IEEE Transactions on Knowledge and Data Engineering, 1995
We define a new fixpoint semantics for rule based reasoning in the presence of weighted information. The semantics is illustrated on a real world application requiring such reasoning. Optimizations and approximations of the semantics are shown so as to make the semantics amenable to very large scale real world applications.
