In this paper, a thesaurus-based methodology is proposed for systematic ontological conceptualization in the manufacturing domain. The methodology has three main phases, namely, thesaurus development, thesaurus evaluation, and thesaurus conversion. A middle-out process is proposed for the thesaurus development. Simple Knowledge Organization System (SKOS) has been used as the thesaurus representation formalism. The concept-based nature of a SKOS thesaurus makes it a suitable medium for identifying important concepts in the domain. To that end, novel thesaurus evaluation and thesaurus conversion metrics that exploit such nature are presented. The ontology conceptualization methodology is demonstrated through the development of a manufacturing thesaurus, referred to as ManuTerms. Concepts in ManuTerms are considered for ontology conceptualization using the proposed thesaurus conversion metrics. The whole conceptualization process is the stepping stone to developing more axiomatic ontologies. Although the proposed methodology is developed in the context of manufacturing ontology development, the underlying logic, tools, and models can be applied to any formal ontology development. The developed thesaurus can serve as a standalone lightweight ontology and its concepts can be reused by other ontologies or thesauri.
