Semantic data modeling – conceptual view
Abstract: In this talk, I will explain the principles of semantic modeling. I
will briefly compare popular data models, such as rational vs. NoSQL databases.
Then, I will focus on graph ontologies. I will describe their features, the
problem of abstraction, information levels (e.g., upper vs. domain ontologies),
and other aspects that are important for semantic modeling. The discussion will
be supported by practical examples that emerged in our research of the semantic
modeling of image content.
Examples from the cybersecurity domain will, in turn, demonstrate the abilities
and limitations of ontologies for detection and mitigation of cyber threats.
Possible utilization of ontologies for formal knowledge modeling in hands-on
cybersecurity training will be presented as well.
