Akio Sashima, Yutaka Inoue, Koichi Kurumatani
2006 Proceedings of the 1st international workshop on Advanced data processing in ubiquitous computing (ADPUC 2006) - ADPUC '06  
The facility of real-time analysis, which includes pe riodical evaluations of spatio-temporal conditions, enables application developers to outsource context-aware mecha nisms.  ...  As described in this paper, we first examine mid dleware of context-aware services and our approaches.  ...  Consequently, spatio-temporal manage ment is an inevitable function of context-aware systems.
