As network and computing technologies have improved, and the number of mobile devices has increased, realizing context-aware personal services has become one of the most important issues in pervasive computing. Semantic technology may help acquiring, organizing, and processing context information. However, most approaches thus far have adopted semantic technology with an ideal point of view, and they have failed to produce feasible performance and scalability. We propose a practical semantic technology adoption strategy for contextaware personal services with respect to conventional technologies. Based on our strategy, we present a context-aware personal service framework with acceptable performance and scalability.
