Ontological Engineering

ontologicalengineering2Ontological Engineering refers to the set of activities that concern the ontology development process, the ontology life cycle, as well as the methodologies, tools and languages required for building ontologies.

Our goal is to provide the guidelines and technologies for more effective and efficient ontology network development, management, and use.

With the goal of speeding up the ontology development and improving the management of ontology development projects, our research is focused on identifying prescriptive methodological guidelines that help software engineers and ontology practitioners to build ontologies as well as on providing the necessary technological support.

Our effort is mainly devoted to the following processes and activities: ontology requirements specification; planning and scheduling; control; reuse and reengineering of non-ontological resources such as lexicons, thesauri, and classification schemes; reuse of general and domain ontologies; reuse of ontology design patterns, collaborative and argumentative ontology development; ontology modeling; ontology dynamics and evolution, multilingual mappings between ontologies, ontology localization, ontology summarization, and ontology evaluation and assessment.

Additionally, we are focused on enriching or grounding non-ontological models (e.g., qualitative models) and terms coming from folksonomies with ontological information. On the other hand, we are investigating agile methods for building lightweight terminologies to be used in the generation of linked data from a set of keywords.

Currently, we are applying our methods and techniques to build ontologies in the following domains and fields: e-government, geography, intellectual property rights, multimedia, and user context.

We are devoted to creating methodologies for building semantic applications, with special emphasis on methodologies for building applications that use linked data.


Currently we have the following projects in execution in this area:

In the past, for this research area, we have worked in the following projects:

Main results

The work done so far in this research area has mainly been focused on providing (a) a general vision of the Ontology Engineering, (b) a methodology, called METHONTOLOGY, for building ontologies from scratch, and (c) the NeOn Methodology Framework for building ontology networks. The NeOn Methodology supports the collaborative aspects of ontology development and the reuse and the dynamic evolution of networked ontologies in distributed environments. It is also a scenario-based methodology that includes methodological guidelines and proposes methods, techniques and tools for carrying out processes and activities, defined in the NeOn Glossary of Processes and Activities.

The following ontologies have been developed by members of the OEG:
