Ontological Engineering Knowledge Representation
Ontological Engineering Knowledge Representation. a general ontology the basic categories representing actions mental events & mental objects 3 Ontological Engineering • Complex domains – e.g. internet shopping agents – require very general & flexible representations • should include actions, time, physical objects, beliefs, …. – ontological engineering • is the process of finding/deciding on representations for these abstract concepts – somewhat like Knowledge Engineering • but at a larger scale • generalized to a more complex real world 4 Ontological Engineering • We use a general framework of concepts – an upper ontology • "upper" due to the diagrammatic convention of putting the most general at the top 5 Ontological Engineering • a sample upper ontology 6 Ontological Engineering – there are limitations to a FOL representation – e.g. there are exceptions to generalizations • they hold only to some degree • "tomatoes are red" • but there are green, yellow, even purple tomatoes – exceptions & uncertainty are important topics • however, they are orthogonal to a general ontology – & their discussions are deferred
