[3H1-GS-3d-04] Towards construction of daily living episode ontology

Approach by reusing “activity and participation” categories in ICF

Keywords:Daily living episode, Ontology

There is research related to commonsense reasoning and robotic agents in a human living environment these days. Handling contexts of human daily living is crucial for the systems e.g. detection of risky situations in a care facility and realizing a long-term natural dialogue system that considers the context of daily living.
This research aims to construct a daily living episode ontology to represent daily living activities by reusing the International Classification of Functioning, Disability, and Health (ICF). This ontology provides the common vocabulary for annotating the context to the sensed data in the daily living environment. We extracted the categories from ICF and constructed the is-a hierarchy.
The constructed ontology contains 284 classes. The evaluation of its coverage is performed by using the extracted samples from two resources of commonsense reasoning, i.e. ATlas Of MachIne Commonsense (ATOMIC) and STAIR Actions captions. We tried to describe the context of each sample retrieved from the resources by using the constructed ontology as an evaluation. The results are 0.63 and 0.84 coverage respectively. A detailed discussion will be written in the paper.
