INFERRING USER CONTEXT VIA TIME-SERIES CORRELATION ANALYSIS

摘要

There is disclosed a technique of associating device activity to a broadcast programme, comprising: receiving a model for a broadcast programme identifying portions of content and portions of breaks in the content; monitoring, via a client software module running on users' mobile devices, said device's active or inactive states; receiving an activity stream of a user device; comparing the activity stream to the model of the broadcast programme to identify a correlation between them; inferring a user of the user device as watching the broadcast programme based on a level of the correlation.
