摘要
Techniques for determining context based on a spatial trail include determining data that indicates a first trail comprising a plurality of locations of finite spatial granularity at a corresponding plurality of times. The techniques also comprise determining data that indicates at least one criterion for belonging in a group. The criterion indicates a first spatial granularity for at least a first location at a corresponding first time in the first trail. The techniques further comprise determining whether a particular entity belongs in the group based, at least in part, on the criterion and a second trail for the particular entity. A trail for any entity comprises a plurality of locations of finite spatial granularity indicating actual locations of the entity at a corresponding plurality of times.
