“Economic and Financial Analysis”, “Accounting” and “Management and<br />

Information Systems”. For the “Economic and Financial Analysis” module, one can<br />

define more courses, structured in pedagogical entities or learning entities. In the<br />

Figure 7 we have presented the component of the course “Analysis of output<br />

activities”, and also the content of two learning entities within it.<br />

4.2. Instantiation of the “Oriented on activity specialization” model using UML<br />

for the ontology that defines the “Economic and Financial Analysis”<br />

in a formative context<br />

The instantiation of the representation model corresponding to the ontology of<br />

“Economic and Financial Analysis”, firstly involved building the domain’s ontology,<br />

by defining the concepts and the relations between the concepts. It is well-known that<br />

the process of building up and improving an ontology is quite difficult. Besides,<br />

building up an operational ontology occurs in three main steps:<br />

• Conceptualization, consisting in identifying the knowledge within a<br />

representative area of the field, regrouping in semantic classes and structuring<br />

them in networks;<br />

• Defining the ontologies, implying the formalization of the conceptual model<br />

attained in the previous step;<br />

• Operationalization, presuming the transcription of the ontology in a formal<br />

and operational language of knowledge representation.<br />

In the present paper we already completed the first two steps. The conceptualization<br />

step was performed based on the reference corpus for the Economic and Financial<br />

Analysis field (guidebooks, books, articles, Web pages and so on). In fact, to<br />

complete the conceptualization step it was absolutely necessary to rely on a thesaurus<br />

created by experts in the field. Regarding the second step, the research team has<br />

proceeded to transcribe the ontology in the UML language.<br />
