Abstract
Context-aware database has drawn increasing attention from both industry and academia recently by taking users’ current situation and environment into consideration. However, most of the literature focus on individual context, overlooking the team users. In this paper, we investigate how to integrate team context into database query process to help the users get top-ranked database tuples and make the team more competitive. We review naive method and propose an optimized query algorithm to select the suitable records and show that they output same results while the latter is more computational efficient. Extensive empirical studies are conducted to evaluate the query approaches and demonstrate their effectiveness and efficiency.
