CONTEXT-AWARENESS STATISTICS ON MOBILE DEVICES

摘要

A context of a mobile device is determined by: when the mobile device is stationary, determining that the mobile device is at a place of interest; inferring a semantic interpretation of the place of interest; and generating an output containing the inferred semantic interpretation. The semantic interpretation is inferred by considering historical data relating to times of day at which the mobile device has been located at the place of interest, and/or relating to days of the week on which the mobile device has been located at the place of interest. The semantic interpretation may be a home, or a primary workplace. The semantic interpretation is inferred by determining location coordinates of the place of interest; and selecting the semantic interpretation based on addresses corresponding to the location coordinates. An output is generated, in the form of a prediction of a place of interest that the mobile device will visit at a future time, based on historical data relating to a sequence in which places of interest are visited. The prediction has an associated confidence level. The output also includes a prediction of a length of time that the mobile device will remain at a place of interest.
