“…In this way, the ontological base or CRO (Core Reference Ontology) is generated, taking the keywords and classifying them to produce a specific taxonomy . In this sense, each concept was characterized as follows: the state, through which policies regulate the other actors; the HEIs, observing the organizational distribution of the faculties, institutes, research units, and departments attached to them; the labor market, taking into account employment agencies, and studies on entering the productive sector [3] [17]; graduates, made up of intrinsic data (hard and soft skills) and extrinsic data (courses, studies and experience); and finally, employment observatories that are already operating in different countries [31] [32]. Then, for each of the actors, a version is generated and validated, finally integrating the one that best fits its description, giving rise to the domain specific ontology or DSO (Domain Specific Ontology).…”
