Extracting Meaningful Contexts from Mobile Life Log

摘要

Life logs include people's experiences collected from various sources. It is used to support user's memory. There are many studies that collect and store life log for personal memory. In this paper, we collect log data from smart phone, derive contexts from the log, and then identify which is meaningful context by using a method based on KeyGraph. To evaluate the proposed method, we show an example of the meaningful places by using contexts and GPS logs collected from two users.
