Towards a Teenager Tailored Ontology: Supporting Inference About the Obesity-Related Health Status

In this paper we outline the general framework of the PEGASO ontology initiated within the European research project Personalised Guidance Services for Optimising lifestyle in teenagers through awareness, motivation and engagement. We present our particular choices regarding the ontology-structure, which should be capable of capturing multiple perspectives aiming at (1) describing a teenager and (2) reasoning about its changes during the time. In the same line, we address several issues related to the modelling of normative concepts related to obesity and depict how the public health concern impacts classification of teenagers according to their phenotype. In particular, we present a fragment of the ontology that supports inference about individuals and a personalised assessment of the obesity-related health conditions.
