I know that ontology is a philosophical term and Computer Science used, but the problem comes from, the computer science uses ontology and ontologies like the same thing , and I tried to set a definition of each of ontology and ontologies and have reached:

Ontology: is the theory of conceptualization classification and expression of specifications of shared conceptualization

ontologies: - stractural frameworks for organizing information and knowledge, and these structures encode by ontology languages (Site Wikipedia helped me in drafting definition ontologies) ontology languages= owl languages

please these definition are true or no

I'm afraid, in order to answer your question whether the definition for the term "Ontology" is correct or not, I first need to know what the following terms mean: "theory", "conceptualization", "classification", "expression", "specification", and "/shared/ conceptualization". So can you please give me a definition for each of these terms? :-)

Ontologies, the kind of structures that are supposed to describe and formalise knowledge about a domain, are countable, so you can have one ontology. Therefore computer science uses both the term ontology and ontologies. But "an ontology" (in computer science) is not the same as "ontology" (in philosophy). Your definitions look good enough to me (knowing that there is not one single unique universal definition).

OWL is the Web Ontology Language. It is used to write down ontologies in files in a way that is compatible with the concepts of the WWW (e.g., it uses IRIs to identify terms, it connects ontologies together via import links). Ontologies can be written in languages that are not Web compliant (e.g., using a first order logic syntax) and therefore not all ontologies must be in OWL.
