Context
Dey (2001) says, “Context is any information that can be used to characterize the situation of entity” where an entity is a person, place, or object that is considered relevant to interactions. In a survey on context modeling approaches, Strang and Linnhoff-Popien (2004) report ontologies as a promising technology for modeling contexts. Wang, Zhang, Gu, and Pung (2004) and Chen, Perich, Finin, and Joshi (2004) propose CONON and SOUPA ontologies, respectively, for modeling contexts in a pervasive and distributed computing environment that contain concepts such as person, location, activity, or action. We define simple ontologies for our purposes modeling a team coordination environment that requires core concepts such as teams, logs, events, and tasks.
