Context Modeling and Measuring for Context Aware Knowledge Management

Abstract

To fully understand and to better reuse knowledge, it's necessary to correlate knowledge with the context under which the knowledge is generated and managed.However, it remains a challenge to support context awareness in knowledge management system.This paper tries to overcome the difficulties by introducing key enabling technologies for context modeling and measuring: The knowledge context ontology correlates knowledge and its contexts through a high level activity based model is defined; The algorithm for Context similarity measurement is designed by exploiting the hierarchical domain structure defined in the context model.
