%X According to the requirement of context-aware computing in ubiquitous environments, this paper proposed a context information data model based on generalized modeling theory with an extensible and multi-leveled hierarchical structure. Moreover, this paper established the context-aware middleware based on the data model which contained context acquisition layer, context handler layer and context access layer. Acquisition layer was used for capturing context information; Handler layer was responsible for context fusion; Access layer implemented the convenient context information access mechanism. Finally, experimental results show that the context-aware middleware has better performance on providing context-aware service.
