A Brief Survey of Ontology Development Methodologies

The Recent Pace of Ontology Development Appears to Have Waned

Some of the leading methodologies, presented in rough order from the oldest to newest, are as follows:

Cyc – this oldest of knowledge bases and ontologies has been mapped to many separate ontologies. See the separate document on the Cyc mapping methodology for an overview of this approach [9]
TOVE (Toronto Virtual Enterprise) – a first-order logic approach to representing activities, states, time, resources, and cost in an enterprise integration architecture [10]
IDEF5 (Integrated Definition for Ontology Description Capture Method) – is part of a broader set of methodologies developed by Knowledge Based Systems, Inc. [11]
ONIONS (ONtologic Integration Of Naive Sources) – a set of methods especially geared to integrating multiple information sources [12], with a particular emphasis on domain ontologies
COINS (COntext INterchange System) – a long-running series of efforts from MIT’s Sloan School of Management [13]
METHONTOLOGY – one of the better known ontology building methodologies; however, not many known uses [14]
OTK (On-To-Knowledge) was a methodology that came from the major EU effort at the beginning of last decade; it is a common sense approach reflected in many ways in other methodologies [15]
UPON (United Process for ONtologies) – is a UML-based approach that is based on use cases, and is incremental and iterative [16].

Some Ongoing KBS/Ontology Projects and Groups

useful Ontology and KR collections

and additional systems under Knowledge Acquisition Tools.
  • Ontology Learning Tools - Automated/assisted techniques for building an ontology. Also see a good survey of ontology learning methods and techniques (OntoWeb deliverable 1.5, A. Gomez-Perez, D. Manzano-Macho).
  • The New Ontology of the Mental Causation Debate - an AHRC (Arts & Humanities Research Council) funded research project, attempting to frame the debate with more metaphysical precision, and explore the consequences of that reframing (Univ Durham, UK).
  • Ontology Merging Tools - See Chimera and PROMPT. Also see Carter, a tool for helping experts build a consensus KB.
  • Ontologies - Dealing with multiple ontologies - See InfoQuilt.
