Title: The Knowledge Dictionary: A KBMS architecture for the many-to-many coupling of knowledge based-systems to databases

Miscellaneous ·
OSTI ID:6047680

The effective management and leveraging of organizational knowledge has become the focus of much research in the computer industry. One specific area is the creation of information systems that combine the ability to manage large stores of data, making it available to many users, with the ability to reason and make inferences over bodies of knowledge capturing specific expertise in some problem domain. A Knowledge Base Management System (KBMS) is a system providing management of a large shared knowledge base for (potentially) many knowledge-based systems (KBS). A KBMS architecture for coupling knowledge-based systems to databases has been developed. The architecture is built around a repository known as the Knowledge Dictionary-a multi-level self-describing framework that facilitates the KBS-DBMS integration. Th Knowledge Dictionary architecture allows the following enhancements to be made to be made to the KBS environment: knowledge sharing among multiple KBS applications; knowledge management of semantic integrity over large-scale (declarative) knowledge bases; and, knowledge maintenance as the declarative portion of the shared knowledge base evolves over time. This dissertation discusses the architecture of the Knowledge Dictionary, and the underlying knowledge representation framework, focusing on how it is used to provide knowledge management services to the KBS applications having their declarative knowledge base components stored as databases in the DBMS. The specific service investigated is the management of semantic integrity of the knowledge base.
