Ontology Research Seminar - Brazil - 2008

Paper published in Ontology Research Seminar, Brazil, 2008.

Domain ontologies have shown a powerful approach for capturing strategic knowledge and is being studied in the Petroleum Geology domain. Geologists apply multiple types of knowledge for problem solving, the visual knowledge being the most important for interpretation task even being hard of representing by ontological primitives. We have proposed the definition of representational primitives of visual knowledge in three levels of abstraction, keeping the symbolic anchor between levels. We have also introduced primitives for temporal ontologies to support the identification of sequences of non-time labeled events. The results of this project were implemented in a petrographic system to support the description and interpretation of reservoir rocks.
