Using ontologies for knowledge management: An information systems perspective

Knowledge management research focuses on the development of concepts, methods, and tools supporting the management of human knowledge. The main objective of this paper is to survey some of the basic concepts that have been used in computer science for the representation of knowledge and summarize some of their advantages and drawbacks. A secondary objective is to relate these techniques to information sciences theory and practice. The survey classifies the concepts used for knowledge representation into four broad ontological categories. Static ontology describes static aspects of the world, i.e., what things exist, their attributes and relationships. A dynamic ontology, on the other hand, describes the changing aspects of the world in terms of states, state transitions and processes. Intentional ontology encompasses the world of things agents believe in, want, prove or disprove, and argue about. Social ontology covers social settings, agents, positions, roles, authority, permanent organizational structures or shifting networks of alliances and interdependencies.
