v1 v2 58 58 The word ''''ontology'''' has been used to refer to all of the above things. When used in the AI/Knowledge Representation community, it tends to refer to things that have a rich and formal logic-based language for specifying meaning of the terms. Both a thesaurus and a taxonomy can be seen as having a simple language that could be given a grammar, although this is not normally done. Usually they are not formal, in the sense that there is no formal semantics given for the language. However, one can create a model in UML and a model in some formal ontology language and they can have identical meaning. It is thus not useful to say one is an ontology and the other is not because one lacks a formal semantics. The truth is there is a fuzzy line connecting these things. 59 59 60 ~~Look here for a paper describing the many uses of ontologies: A Framework for Understanding and Classifying Ontology Applications (http://sern.ucalgary.ca/KSI/KAW/KAW99/papers/Uschold2/final-ont-apn-fmk.pdf Rob Jasper and Mike Uschold.)~~ 60 Look here for a paper describing the many uses of ontologies: A Framework for Understanding and Classifying Ontology Applications (http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.39.6456&rep=rep1&type=pdf Rob Jasper and Mike Uschold.) 61 61 62 62 There is a very close relationship between a meta-model and an ontology, but it is not necessarily equivalence.
