The behavioural science team is developing an ontology specific to behaviour change interventions – the Behaviour Change Intervention Ontology (BCIO). The BCIO is a set of definitions for entities and relationships used to describe behaviour change interventions, their contexts, effects and evaluations. It is being used to structure the evidence in intervention evaluation reports and provides a structured framework to underpin the training of the system. Computer scientists use the resulting data structure to create algorithms which can gather and synthesise relevant information from research reports more rapidly than current methods for systematic reviewing allow.
