  Abstract In the area of information system design, the development of context-aware systems which can provide relevant information in a context-driven fashion to support mobile users in crisis management tasks represents a great challenge. Motivated by the fact that police officers are often overwhelmed by too much information, the goal of the MOSAIC project (a multi-officer system of agents for informed crisis control) is to support mobile police officers by a system which delivers contextualized information that is relevant to the task at hand. In order to elicit the information requirements of police officers who are involved in crisis situations, a questionnaire-based requirements elicitation study has been carried out in the context of the work described here. The results mainly shed light on the situation-specific information requirements of police officers in certain scenarios. The design requirements that follow from our study have clearly the potential to guide the design of context-based information delivery systems for users involved in critical situations such as the police officers we target. Our findings thus offer an important contribution to the field of information system design for crisis management.

  Title A rule-based system for contextualized information delivery Type Conference Article
  Year 2011 Publication 8th International Conference on Information Systems for Crisis Response and Management: From Early-Warning Systems to Preparedness and Training, ISCRAM 2011 Abbreviated Journal ISCRAM 2011  
  Volume Issue Pages  
  Keywords Information systems; Semantic Web; Context-aware informations; Information requirement; Precision and recall; Quantitative evaluation; Rdf; Rule-based system; Sources of informations; Sparql; Law enforcement  
  Abstract When carrying out tasks, police officers need up-to-date information contextualized to their current situation to support them in decision making. The results of a previous user study with the aim of capturing the information requirements of police officers have led to the implementation of a rule-based system for contextualized information delivery. In this paper, we present the overall system and discuss how the various sources of information are modelled using ontologies. Our focus is on the formalism for expressing the rules and the engine executing those rules to decide which information is relevant for specific users. These declarative rules can be modified independently of the code executing them, thus providing a principled way to adapt the system to new domains. Quantitative evaluations on scenarios constructed in cooperation with police officers show that precision and recall levels of our system are satisfactory compared to other systems and that our system can be adapted to new scenarios with reasonable efforts.
