EDEM-CONNECTONTO: Dementia Agitation Ontology for Caregiver Support

An ontology of dementia-related agitation developed to support informal caregivers. It contains 252 concepts, 16 relations, and 241 individuals, formalizing knowledge about agitation types, causes, consequences, and non-pharmacological interventions. The ontology was created by Sumaiya Suravee through literature review, expert workshops, and caregiver interviews, and is implemented in OWL.

Use Cases

• Constructing knowledge graphs for caregiver-support applications based on the formalized domain knowledge.
• Enabling ontology-guided data annotation for digital support systems based on the structured semantic foundation.
• Developing GraphRAG-based applications for identifying agitation patterns based on the modelled concepts and relations.
• Supporting informal caregivers in selecting appropriate care strategies based on the modelled types of agitation and interventions.

Strengths

• Contains 252 formally defined concepts, providing a detailed semantic structure.
• Includes 16 relations and 241 individuals, offering a specific level of detail for modelling.
• Validated with Protégé and meets standards for biomedical ontologies, indicating a level of formal quality.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 1.4 MB PDF file, which may not be the most accessible format for direct computational use.
