DOKMF: Distributed Ontology-Based Knowledge Management Framework

This paper proposes a distributed ontology-based knowledge management framework-DOKMF. An autonomous organization unit is reified as a knowledge node, and virtual communities established according to interests are reified as knowledge communities with some semantic synergy. Global ontology provides a basic glossary of terms and relationships between terms in the domain. Local ontology organizes context-based local knowledge according to local systems. The mappings based on the context address issues of querying and collisions between different local ontologies by a multi- similarities strategy process. This distributed ontology-based design provides the members of a virtual community with more flexible, efficient, adaptable, semantic-based and intelligent knowledge management services.
