METHONTOLOGY

Methontology is a methodology for ontology development that provides a structured, life-cycle based approach to building ontologies. Introduced in the late 1990s by researchers in the ontology engineering field, it aims to bridge theoretical commitments about a domain with practical engineering practices. The methodology outlines a systematic process that covers requirements specification through deployment and ongoing maintenance.

The Methontology life cycle typically comprises several activities: specification (gathering requirements and delimiting scope), conceptualization (defining the domain’s key concepts and relationships), formalization (selecting a formalism and organizing concepts into a formal ontology), implementation (coding the ontology in a chosen representation language), and maintenance and evaluation (ongoing validation, documentation, versioning, and reuse). Many presentations include iterative feedback loops, allowing revisiting earlier phases as understanding evolves.

Key principles associated with Methontology include explicit ontological commitments, modular and reusable design, thorough documentation, and alignment with existing ontologies to promote interoperability. The approach emphasizes verification and validation, stakeholder involvement, and the reuse of standards and patterns to support scalability and quality in complex domains.

Impact and reception: Methontology helped shape early comprehensive approaches to ontology engineering and is frequently cited in academic literature and textbooks. It has influenced subsequent ontology development life cycles, tooling, and best practices, contributing to a foundation for systematic ontology design and evaluation across diverse application areas.
