| 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. |

| Abstract |
The importance of distinguishing between direct and indirect losses of disasters is stressed. In order to estimate indirect losses, a conceptual framework of direct and indirect losses is presented. For the case of the Great Hanshin-Awaji (Kobe) Earthquake of 1995, direct stock losses of both the manufacturing and the commercial sectors record almost same size of big damage. As for indirect flow losses, the commercial and the other services sectors show far greater damage than the manufacturing sector. A careful statistical analysis of indirect losses using the gross regional product in the stricken area presents a new finding that the lost product and income in terms of estimated indirect losses are quite large and continue to arise for longer than 10 years, mounting to some 14 trillion yen (about US$0.13 trillion). Disaster management policy should be improved by paying attention not only to direct losses but also to indirect losses. |
