Dear Marcelino,

 

I’ll take a crack at these:

 

Construct: A syntactic structure that is itself devoid of meaning, but can have many meanings placed on it. E.g. the subject, verb, object structure can take on different meanings with the use of different subjects, objects, and verbs.

 

Primitive: A term that is not fully defined  by logical constructs in terms of other terms in a theory (a text definition does not count). For example, a class that is defined as the intersection of two other classes is fully defined and is not primitive. A class that is defined as a subtype of anther class, but has no other axioms restricting membership is primitive – it is only partially defined.

 

Term: An identifier in a logical theory. In general a term has an intended interpretation, and is often named in terms of this intended interpretation. However, other models of the theory may exist.

 

Regards

Subject: [ontolog-forum] Constructs, primitives, terms

 

Hi...

 

Along my studies in the subject of ontologies, i perceived that i have some doubts about the meaning of some terms which generally appear in the literature. My doubts are (mainly) regarding to the following terms: Construct, primitive, term. What each of them means in the context of ontology? How they are related?

 

Thanks.
