There are a number of standards aiming to facilitate the exchange of competence data in the educational and job market areas. Despite their relevance, we have observed that they could benefit from an in-depth analysis of the notion of competence, given its central role in the intended application areas. This includes addressing facets of competence...

Several efforts that leverage the tools of formal on-tology have demonstrated the fruitfulness of considering key metaproperties of classes in ontol-ogy engineering. Despite that, it is still a common practice to apply representation schemes and approaches-such as OWL-that do not benefit from identifying ontological categories and simply treat all...

The problem of using structured methods to represent knowledge is well-known in conceptual modeling and has been studied for many years. It has been proven that adopting modeling patterns represents an effective structural method. Patterns are, indeed, generalizable recurrent structures that can be exploited as solutions to design problems. They ai...

Formal Ontology is a discipline whose business is to develop formal theories about general aspects of reality such as identity, dependence, parthood, truthmaking, causality, etc. A foundational ontology is a specific consistent set of these ontological theories that support activities such as domain analysis, conceptual clarification, and meaning n...

Several efforts that leverage the tools of formal ontology (such as OntoClean, OntoUML, and UFO) have demonstrated the fruitfulness of considering key metaproperties of classes in ontology engineering. These metaproperties include sortality, rigidity, and external dependence, and give rise to many fine-grained ontological categories for classes, in...

Diverse types of Knowledge Organization Systems (KOS) can be built using Semantic Web technologies, with distinct objectives and formality levels. In this paper, we focus on two of them, lexicons and thesauri, which can be specified using the Ontolex-Lemon and the Simple Knowledge Organization System (SKOS) vocabularies, respectively. Because thesa...

Conceptual models are artifacts representing conceptualizations of particular domains. Hence, multi-domain model catalogs serve as empirical sources of knowledge and insights about specific domains, about the use of a modeling language’s constructs, as well as about the patterns and anti-patterns recurrent in the models of that language crosscuttin...

Provisioning is an important activity in the configuration of networks. The ITU-T Recommendation M.3400 defines network provisioning as the "procedures which are necessary to bring an equipment into service, not including installation". Resource and service provisioning are recent challenges in communication network planning and important activitie...

Standards are documents that aim to define norms and common understanding of a subject by a group of people. In order to accomplish this purpose, these documents must define its terms and concepts in a clear and unambiguous way. Standards can be written in two different ways: by informal specification (e.g. natural language) or formal specification...

The SNMP protocol remains a broadly adopted technology in the Internet management framework and its MIB was proposed to guarantee interoperation. In order to enable the management of new equipment, the human manager must compile the correlated MIB file (MIB description) and choose the right objects to manage an implicit knowledge. This paper prese...

OntoUML and OWL are ontology languages appropriated to different knowledge representation levels. In order to have better knowledge representation and reasoning capabilities in OWL ontologies, an Ontology Engineering should be used – which corresponds to the transformation of a conceptual model ontology language, such as OntoUML, to a computational...

Normative Acts are important legislative and regulatory documents made by different governmental organs. Every year, a huge amount of information is provided in Normative Acts by these organs without control, i.e., there is no effective way to verify redundancies, inconsistencies, crossimpact and ambiguities. In this paper, we propose a domain onto...

The construction of large-scale reference conceptual models and ontologies is a complex engineering activity. To develop high quality models, a modeler must have the support of expressive engineering tools such as theoretically well-founded modeling languages and methodologies, ontological patterns and computational environments. Patterns and Anti-...

The ITU-T Recommendation G.805 is a telecommunication standard providing a generic functional architecture for transport networks and serving as the basis for several others networking and management specifications. Due to its fundamental importance, it is essential for this recommendation to be clear, complete and unambiguous, thus eliminating the...

This paper describes an ontology model (conceptual model) based on the ITU-T Recommendation G.805 for transport network architectures. The goal is to take a step forward to the autonomic applications fortransport network operation and management. Besides the conceptual model description and explanation, including its main elements (classes, propert...

This paper presents the OOTN - ontology for optical transport networks: a computational ontology proposal for optical transport networks based on the ITU-T G.805 and G.872 recommendations. It shows the most relevant issues found during the modeling process and presents a case study where the classical concepts of VTD and RWA applications have been...
