| Zusammenfassung |
| With the proliferation of the geospatial technologies on the Internet, the
role of geo-portals (i.e. gateways to Spatial Data Infrastructures) in the
area of wildfires management emerges. However, keyword-based techniques
often frustrate users when looking for data of interest in geo-portal
environments, while little attention has been paid to shift from the
conventional keyword-based to navigation-based mechanisms. The presented
OntoFire system is an ontology-based geo-portal about wildfires. Through the
proposed navigation mechanisms, the relationships between the data can be
discovered, which would otherwise not be possible when using conventional
querying techniques alone. End users can use the browsing interface to find
resources of interest by using the navigation mechanisms provided. Data
providers can use the publishing interface to submit new metadata, modify
metadata or removing metadata in/from the catalogue. The proposed approach can
improve the discovery of valuable information that is necessary to set
priorities for disaster mitigation and prevention strategies. OntoFire
aspires to be a focal point of integration and management of a very large
amount of information, contributing in this way to the dissemination of
knowledge and to the preparedness of the operational stakeholders. |
