Representing and reasoning over a taxonomy of part-whole relations
TLDR
A formal taxonomy of types of mereological and meronymic part-whole relations is presented that distinguishes between transitive and intransitive relations and the kind of entity types that are related. Expand

The Use of Foundational Ontologies in Ontology Development: An Empirical Assessment
  • C. Keet
  • Computer Science
  • ESWC
  • 29 May 2011
TLDR
There is an assumption that ontology developers will use top-down approach by using a foundational ontology, because it purportedly speeds up ontology development and improves quality and interoperability of the domain ontology. Expand
Enhancing Comprehension of Ontologies and Conceptual Models Through Abstractions
  • C. Keet
  • Computer Science
  • AI*IA
  • 10 September 2007
TLDR
In addition to the Database Comprehension Problem, where diagrammatic conceptual data models are too large for a modeller or domain expert to comprehend or manage, an Ontology ComprehensION Problem is emerging. Expand
Factors Affecting Ontology Development in Ecology

  • 20 July 2005
TLDR
We have created a formal mapping between the software-supported ecological modeling method and software tool STELLA and ontology elements, which simplifies bottom-up ontology development considerably and has excellent potential for semi-automated ontological development. Expand
Formalising Temporal Constraints on Part-Whole Relations
TLDR
In this paper we face the issue of imposing temporal constraints on part-whole relationships, introducing a way to account for essential and immutable parts (and wholes) in addition to the usual mandatory parts, which distinguishes between rigid and anti-rigid classes. Expand
Functional Dependencies in OWL ABOX
TLDR
Functional Dependency (FD) has been extensively studied in database theory. Expand
Dependencies between ontology design parameters
  • C. Keet
  • Computer Science
  • Int. J. Metadata Semant. Ontologies
  • 1 September 2010
TLDR
Ontology development methodologies provide scenarios, but they do not address the dependencies between the permutations at the different stages in the development process. Expand
A Basic Characterization of Relation Migration
TLDR
Representing and reasoning over evolving objects has been investigated widely. Expand
The Data Mining OPtimization Ontology
TLDR
The Data Mining OPtimization Ontology (DMOP) has been developed to support informed decision-making at various choice points of the data mining process in view of extracting patterns associated with mining performance. Expand
