Emerging Technologies and Standards

Common Alerting Protocol (CAP) is an open standard for the exchange of emergency alerts and public warning over data networks, computer-controlled public warning systems, and emergency management software applications. CAP allows a consistent warning message to be disseminated simultaneously over many different warning systems, thus increasing warning effectiveness while simplifying the alerting task. Using CAP, emergency responders can: Ensure alert messages reach the right audience at the right timeReduce the workload and costs associated with multiple warning systemsEnhance technical reliabilityEnsure consistency in the information transmitted over multiple delivery systemsReduce costs and operational complexities by eliminating the need for multiple custom interfaces to warning sources and dissemination systems

The web interface is split up into the four different pages (1) Dashboard, (2) Social Media (SM) activity, (3) App activity and (4) Settings. The dashboard is the default page featuring the display of alerts within the map view and list of alerts to provide a quick orientation (Figure 2). Following the CAP standard, alerts are categorised as either ‘Fire’, ‘Meteorological’, ‘Transport’ or ‘Other’, the latter comprising all other CAP categories. We chose to only integrate the most relevant subset of categories for our scenarios (cf. section 5.3) to keep the interface clear and simple. Each category has its own symbol, which is used on the map, list and alert counters above. Furthermore, using text input fields, the user can define a distinct set of complex Boolean keywords for each category, such as ‘Dortmund (fire, bomb)’ for the fire category. In this example, the results are filtered by social media messages that contain the term ‘Dortmund’ as well as ‘fire’ and/or ‘bomb’. At the top-right corner, the user may enter the settings page to define the sets of keywords (information gathering).

It is an important issue for governments to handle emergencies caused by natural disasters, e.g., earthquakes, flood, etc., in order to save money and life. The OASIS (Organization for the Advancement of Structured Information Standards) technical committee on emergency management has defined the CAP (Common Alerting Protocol) standard1 to facilitate interagency emergency communications. In Taiwan, based on the open data initiatives, a governmental website2 has also been built as a platform to release official warning messages.
