Understanding an Ontology through Divergent Exploration

Abstract

Abstract. It is important that the ontology captures the essential conceptual structure of the target world as generally as possible. However, such ontologies are sometimes regarded as weak and shallow by domain experts because they often want to understand the target world from the domain-specific viewpoints in which they are interested. Therefore, it is highly desirable to have not only knowledge structuring from the general perspective but also from the domainspecific and multi-perspective so that concepts are structured for appropriate understanding from the multiple experts. On the basis of this observation, the authors propose a novel approach, called divergent exploration of an ontology, to bridge the gap between ontologies and domain experts. Based on the approach, we developed an ontology exploration tool and evaluated the system through an experimental use by experts in an environmental domain. As a result, we confirmed that the tool supports experts to obtain meaningful knowledge for them through the divergent exploration and it contributes to integrated understanding of the ontology and its target domain.

Multistep expansion based concept search for intelligent exploration of ontologies

“…Future works include an integration of the proposed method and other ontology exploration methods such like our previous works [1,2], application of the system for other ontologies, and improvements of the system through feedbacks from them.…”

“…In previous works, the authors proposed divergent exploration of ontology and showed it contribute to the user's understanding of ontology according to their intention and interests [1,2]. Ontology explorations are done through finding concepts related with a focused concept and trace them repeatedly.…”

Dashboard by-example: A hypergraph-based approach to on-demand data warehousing systems

“…Most of semantic web applications use ontologies as vocabularies to describe metadata and are aimed at semantic processing of them [20]. Regarding ontology as the exploration target, the main DBE approache is composed of: (1) the systematized conceptual structure of ontologies and (2) on the fly conceptual structures identification from the ontologies to cope with various dashboard interests.…”

Ontology exploration tool for social, economic and environmental development

“…The framework defines six (6) locally-led innovation lifecycle phases; needs, strategy, incubation, localization, evaluation, and creation. It is refined via four (4) [1]. This paper focuses on semantic knowledge management for the SEED framework.…”

“…Annotating metadata using terms defined in ontologies enable users to search data across domains (Layer 0-1). A divergent ontology exploration tool can generate comprehensive conceptual maps from user's multiple arbitrary perspectives [4]. The exploration tool allows the user to explore ontologies interactively according to their interests.…”
