Abstract: Methods and apparatus are disclosed to identify users associated with device application usage. A disclosed example method involves obtaining demographics of persons to participate in a panel for an audience research study, identifying a set of applications to be monitored, providing devices associated with the persons in the panel with a meter to record usage of the applications and with a user-to-application associator, the user-to-application associator to define associations between the applications to be monitored and the persons associate with the device before the applications are launched, receiving data from a first one of the devices identifying a first one of the persons as a primary user of a first one of the applications in the set of applications, receiving data from the first device identifying usage of the first application, and associating the demographics of the first person with the usage of the first application.

Abstract: An example includes a segment collector to: access impression records indicative of media access segments, the media access segments including start times and end times corresponding to media accessed by a panelist; and determine ones of the impression records that include a watermark corresponding to a first media platform presenting the media; a segment classifier to convert a first one of the impression records including the watermark to a converted impression record; and combine the converted impression record corresponding to the first media platform and a second impression record corresponding to a second media platform; and a media creditor to generate audience measurement metrics based on the combined impression records.

Abstract: Methods, apparatus, systems and articles of manufacture are disclosed for determining media access sessions. In an example, an apparatus to determine media access sessions includes a record locator to access, in a data store, a first media impression record indicative of a first media access segment, and a second media impression record indicative of a second media access segment and a view counter. The view counter is to update at least one of the first or second media impression records in the data store, when the second media access segment occurs within a threshold time after the first media access segment, to indicate that the first and second media access segments are associated with a same first media access session.
