Building ontologies in
the 1990s and 2000s Methodologies for building single ontologies do not consider the reuse of knowledge • Uschold and King’s method • Grüninger and Fox’s methodology • KACTUS approach • METHONTOLOGY • SENSUS method • On-To-Knowledge • DILIGENT Ontology learning approaches for building ontologies from structured, semi-structured and non-structured data • Are not integrated with current methodologies • Mainly from non-structured data using NLP techniques Ontological Engineering 12 © A.

Key issues • Reuse
of proprietary knowledge-aware resources • Heterogeneity – Terms are in different languages – Different conceptualization (different ways of organizing job categories) – Different DB schemas • Data must be kept in the original sources and in their own language. Ontological Engineering 21 © A. Gómez Pérez, M.C. Suarez de Figueroa, B. Villazón, E.Montiel, G. Aguado, M. Espinoza
22.
Key aspects of
Ontological Engineering • Ontologies – Single versus network of ontologies? – Are ontologies built from scratch or reusing knowledge-aware resources? – Are mappings used for solving conceptual mistmaches? • Instances – Where are the data/instances? • Instances are in the ontology • Instances are in RDF files independently of the ontology • Data are kept in the original sources – Are instances distributed or centralized? – Have instances a very high rate of changes? – Heterogeneous provenance of instances – Degrees of data quality – Permissions Ontological Engineering 22 © A. Gómez Pérez, M.C. Suarez de Figueroa, B. Villazón, E.Montiel, G. Aguado, M. Espinoza

Conclusions 1. The NeOn
methodology facilitates the reuse and reengineering of non ontological resources into ontologies 2. The reuse of non-ontological resources that have been reached some degree of consensus in a community allows the development of ontologies easier and quicker Ontological Engineering 53 © A.
