Towards a Conceptual Framework and Metamodel for Context-Aware Personal Cross-Media Information Management Systems
4 likes1,035 views
The document discusses a conceptual framework and metamodel for context-aware personal cross-media information management systems, titled the Object-Concept-Context (OC2) framework. It outlines various layers such as object, concept, and context layers, and their interconnections, while addressing issues like information fragmentation and integration of context. Additionally, it mentions future work including implementation and evaluation strategies for the framework.
