• Setting properties for each class;
• Define the characteristics associated with the properties (type, scope and co
domain, the axioms, if any, etc.);
• The creation of instance, which supposedly define individuals for classes, as
well as updating the property with the appropriate values.
A general methodology, in 6 steps, it is proposed in (Peffers K. et al., 2007):
• Identification of the problem and motivation (solution justification);
• Definition of the objectives of a solutions derived from the definition of the
problem;
• Ontology design and development;
• Demonstration of utility items obtained previously in solving of one or more
instances of the problem;
• Evaluation of solution in relation to the problem;
• The communication.
Of these methodologies, we choose on the proposed (Noy N.F. & McGuinness D. L.,
2001), because is much closed to information systems modeling and design
methodologies and, additionally, is a methodology that is mapped very well on
Protégé logic tool used in our research.
3. THE PROPOSED ONTOLOGY FOR ENTERPRISES REPRESENTING
ON THE WEB
The steps followed for development of the enterprise's own ontologies are, according
to the general guide for the ontologies preparation (Noy N.F. & McGuinness D. L.,
2001), the following:
3.1. Domain and scope determination for the ontology
Proposed ontology aims description of an enterprise in the light of information and
knowledge traced by potential users-beneficiaries: products and services supplied,
jobs offer, as well as indicators that can provide a picture of the economic-financial
condition of the enterprise. As potential users, we have in mind traders interested in
finding a vendor for a particular product or service, investors on financial market and
the people who watch finding a job.
3.2. The re-use of the existing ontologies in the field
The best known ontologies for enterprise are published only in the stage of conceptual
models, they are not implemented and in a language (such as OWL) to allow their
import by anonymous users. We have in mind here: TOronto Virtual Enterprise
(TOVE), ontology developed by a group of researchers at the Toronto University,
Resources-Events-Agents (REA) proposed by McCarthy, Business Model Ontology
(BMO) developed by Osterwalder and Pigneur (Osterwalder A. & Pigneur Y., 2002)
etc. By shared ontologies, most are either too complex or contain irrelevant our
objective elements (are focusing only on certain activities – sales, supply chain
management, etc. or approaches the enterprise only in terms of organizational). In
conclusion, the proposed new ontology does not contain any item imported from
another formal existence on the WEB.
