The ontologies specific to the landslide scenario can be accessed here:
In addition to these ontologies, JSI created a set of topic ontologies available at (http://marquis.ijs.si/alexandra/envision/landslides/) using the OntoGen tool. They are obtained using documents provided by domain experts from the landslides domain.
These ontologies contain relevant concepts for the case studies, however they are not complete. The extension of the ontologies can be done manually by loading them into an editor. Two types of files can be used to extend existing ontologies:
- the files with .owl extension can be loaded in ontology editors, such as Protégé
- the files with .rdf and .bow extensions can be loaded in OntoGen
For the landslides domain, two ontologies were built. The first ontology was created by using a document corpus obtained from glossaries. The second one was generated in similar way but extended with information from scientific articles. The first ontology contains 17 concepts grouped under three concepts descending from the root: (risk, hazard, losses), (landslide, earth, maps), and (probability, timely, water). The second ontology contains 28 concepts grouped again under three concepts descending from the root: (water, debris, earth), (zoning, susceptibility, mapping), and (landslide_risk, losses).
We consider the second ontology to have more suggestive concepts, compared to the first ontology. It can be observed that the first ontology may refer to the physical phenomenon of landslides. The second ontology refers to the process of building maps for landslides representation and the third one could refer to risk management in case of landslide events. The name of the concepts are obtained using the default setting of OntoGen, which gives the first three keywords of the documents cluster under those specific concepts. A detailed report of these ontologies can be found in D4.2.
