Abstract

The heterogeneity of information formats is a well-known problem that affects organizations and communities that want to access public data. Today, most public agencies provide access to their data, but the great majority is unreadable by automated mechanisms, even when they in digital formats (doc, pdf, xls, images, etc.) and without even a dictionary meaning for the published content. A solution to this problem is of particular importance to emergency response organizations that need access to all information available to better respond to disasters and crisis. The linked open data (LOD) initiative allows the interconnection of data, using standards in the context of the semantic web approach. In ideal conditions, government agencies publish their public data, thus allowing the use of automated data concerned consumers, whether they are other government agencies or citizens. Efforts aimed to link government data are growing in several countries around the world. This talk presents the LOD concepts and describes an architecture that uses LOD in the design of an Emergency Management System. It describes a scheme for collecting available data from government agencies, such as departments of health, transport, works, that can supply information needs during an emergency response operation. The proposed architecture components are disposed in six layers. Four of them are already present in a typical information system: data, integration, application and user layer, and two others were specially created to support the recommendations of Linked Data: Raw to Linked Data Processing Layer and Semantic Layer. Some other uses of the architecture are also introduced.
