Modular Graphical Ontology Engineering Evaluated

Abstract

Ontology engineering is traditionally a complex and timeconsuming process, requiring an intimate knowledge of description logic and predicting non-local effects of different ontological commitments. Pattern-based modular ontology engineering, coupled with a graphical modeling paradigm, can help make ontology engineering accessible to modellers with limited ontology expertise. We have developed CoMo-dIDE, the Comprehensive Modular Ontology IDE, to develop and explore such a modeling approach. In this paper we present an evaluation of the CoModIDE tool, with a set of 21 subjects carrying out some typical modeling tasks. Our findings indicate that using CoModIDE improves task completion rate and reduces task completion time, compared to using standard Protégé. Further, our subjects report higher System Usability Scale (SUS) evaluation scores for CoModIDE, than for Protégé. The subjects also report certain room for improvements in the CoModIDE tool-notably, these comments all concern comparatively shallow UI bugs or issues, rather than limitations inherent in the proposed modeling method itself. We deduce that our modeling approach is viable, and propose some consequences for ontology engineering tool development.

“…The construction of the model followed the eXtreme Design (XD) methodology (52,53), an agile methodology for KG construction based on the reuse of Ontology Design Patterns (38) (ODPs). ODPs provide solutions to recurrent modelling issues, guaranteeing a high level of ontology quality (54); previous work has demonstrated their positive impact on KG engineering and quality (55,56). The ontology definition is accompanied by the actual mapping of available data with the…”

Time is ripe to embrace the scientific approach in Applied Ontology

“…Stanford's Protégé 4 ) that help the authoring of ontologies. In particular, we reference a plug-in for that platform, called CoModIDE, which enables graphical modeling, and has been shown to speed up the modeling process, especially for those who are not ontologists (Shimizu et al, 2020a).…”

Towards a Modular Ontology for Space Weather Research

“…The OWL files for the pattern, module, and ontology can be found online, as well as our supplementary data. 4 The OWL files were generated using the CoModIDE plugin [8] and annotated with OPLa [3,2] using the OPLa Annotator plugin [9]; both plugins are for Protégé 5…”

“…Algorithm is very domain dependent and we leave it to be specified in specific use-cases. Axiomatization This axiomatization was produced using the out-of-the-box axioms depicted in the Edge Inspector tool in CoModIDE [8], as well as the same axioms used during the systematic axiomatization process particular to Modular Ontology Engineering [11]. They are provided in description logic syntax below.…”
