SSDOnt: An Ontology for Representing Single-Subject Design Studies

Area of Science:

• Biomedicine
• Education
• Behavioral Science

Background:

• Single-subject designs are crucial in education and biomedicine.
• Current search methods for these studies are limited due to a lack of formal vocabulary.
• A need exists for detailed annotation of study configurations and results.

Purpose of the Study:

• To introduce SSDOnt, an ontology for describing and annotating single-subject design studies.
• To facilitate complex querying of single-subject design research data.
• To establish a standardized vocabulary for this research methodology.

Main Methods:

• Developed using the NeOn methodology.
• Formal model defined in Description Logic.
• Implemented using OWL 2 DL ontology language.

Main Results:

• SSDOnt provides a reference model for annotating single-subject design studies.
• The ontology covers key components: phases, interventions, outcomes, and results.
• Demonstrated extensibility for specific interventions (e.g., autism) and query examples.

Conclusions:

• SSDOnt successfully addresses the need for comprehensive description in single-subject research.
• The ontology enhances information retrieval and analysis of single-subject design studies.
