Lifelog-Based Activity Ontology Representation Approach for Disadvantaged Groups


  • School of Computer and Communication Engineering, Daegu University, Gyeongsan 38453, Republic of Korea


In this paper, we propose an approach of a lifelog-based activity ontology representation that expresses activity logging, activity tracking, and activity reasoning. In addition, we analyze related research works, and then we classify them based on our defined ontology. Especially, we design the activity ontology model, then we evaluate the proposed approach by utilizing developed systems for disadvantaged groups. Furthermore, we expect that the proposed approach can be utilized to develop rehabilitation application for the disabled and non-disabled people.
