Typically, when carrying out the task at hand, police officers need to have up-to-date information contextualized to their current situation in order to support their decision making. In contrast to the traditional work environments in which workers are involved in standard office work, the situations in which mobile workers perform their tasks are characterized by various types of context. This feature requires the designers of a system serving those mobile users to understand which context dimensions might influence the users’ information needs; thus, developers must find solutions that enable applications to adapt their behaviour to the current context without consuming too much of users’ attentions. In this thesis we designed a generic architecture supporting delivery of contextualized information that can assist mobile users to take decisions during their activities. Within the MOSAIC project, aiming to enhance situation awareness of emergency responders, we developed a rule-based system which can assess the relevance of information items by taking into account the contextual situations police officers are involved in. Following our quantitative evaluation method, we evaluated the effectiveness and adaptability our system based on realistic scenarios in cooperation with end-users. The competitive results have shown that the system can select adequately relevant information for end-users given their contexts and thus demonstrated the feasibility of the architecture we designed.
