“…Our findings build nevertheless upon the results on these previous works, some of the most important of which we will mention in this section. Ontology engineering has been subject of several analytical surveys, which assessed ontology engineering methodologies from the theoretical perspective and identifies open issues in the field from its early days (Grüninger & Fox, 1995;Jones, Bench-Capon, & Visser, 1998;Lenat, 1995;Noy & Hafner, 1997;Peterson, Andersen, & Engel, 1998) to the time that preceded the advent of Linked Data (Cardoso, 2007;Corcho, Fernández-Lopéz, & Gómez-Pérez, 2003;Hepp, 2007;Paslaru-Bontas & Tempich, 2006;Simperl, Mochol, & Bürger 2010;Sure, Tempich, & Vrandecic, 2006). The most recent of these studies attested the maturity of ontology engineering as an established engineering discipline, with methodologies used in projects whose success critically depends on a systematic operation of the engineering process, and a constantly improving tool landscape facilitating the involvement of lay users at various stages of the ontology life cycle.…”
