This book describes in detail the relationship between symbolic representations of knowledge and abstract states of knowledge, exploring along the way the foundations of knowledge, knowledge bases, knowledge-based systems, and knowledge representation and reasoning. The idea of knowledge bases lies at the heart of symbolic, or "traditional," artificial intelligence. A knowledge-based system decides how to act by running formal reasoning procedures over a body of explicitly represented knowledge—a knowledge base. The system is not programmed for specific tasks; rather, it is told what it needs to know and expected to infer the rest. This book is about the logic of such knowledge bases. It describes in detail the relationship between symbolic representations of knowledge and abstract states of knowledge, exploring along the way the foundations of knowledge, knowledge bases, knowledge-based systems, and knowledge representation and reasoning. Assuming some familiarity with first-order predicate logic, the book offers a new mathematical model of knowledge that is general and expressive yet more workable in practice than previous models. The book presents a style of semantic argument and formal analysis that would be cumbersome or completely impractical with other approaches. It also shows how to treat a knowledge base as an abstract data type, completely specified in an abstract way by the knowledge-level operations defined over it.
In this book, we incrementally specify, semantically characterize, and illustrate with examples, the concepts and tools necessary to the development of Evolving Knowledge Bases (EKB). An EKB is a knowledge base which can not only be externally updated, but is also capable of self evolution by means of its internally specified behavior. To this purpose, we first define the notion of Dynamic Logic Programming, based on the concept of Logic Program Updates, which characterizes knowledge given by a sequence of logic programs, each representing a state of the world. Then, we set forth a language capable of uniformly specify both the external updates as well as the knowledge base's internal behaviour and its updates.
Papers direct the focus of interest to the development and use of conceptual models in information systems of various kinds and aim at improving awareness about general or specific problems and solutions in conceptual modelling.
Creating Knowledge Based Organizations brings together high quality concepts and techniques closely related to organizational learning, knowledge workers, intellectual capital, and knowledge management. It includes the methodologies, systems and approaches that are needed to create and manage knowledge based organizations.
This volume provides comprehensive single-volume coverage of both the theory and the applications of knowledge-based systems.
