Methods and apparatus for determining audience metrics across different media platforms
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.
1. An apparatus to generate audience metrics across different media platforms, comprising:
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.
2. The apparatus of claim 1 , further including a viewing segment sorter to arrange the ones of the impression records including the watermark in a chronological order to identify adjacent ones of the impression records, the chronological order based on times the impression records were attributed to the panelist.
3. The apparatus of claim 1 , wherein the segment classifier is to determine a time period separating adjacent first and second ones of the media access segments of the ones of the impression records including the watermark, the time period defined by an end time of the first one of the media access segments and a start time of the second one of the media access segments.
4. The apparatus of claim 3 , wherein the time period defines a duration during which the media was not presented via the first media platform between the first one of the media access segments and the second one of the media access segments.
5. The apparatus of claim 3 , wherein the segment classifier is to determine if the time period exceeds a threshold, the threshold corresponding to a maximum duration between adjacent media access segments for the adjacent media access segments to be considered a part of a same media access session.
6. The apparatus of claim 1 , wherein the segment classifier is to convert the ones of the impression records including the watermark into views, the views determined based on a threshold corresponding to a maximum duration between adjacent media access segments.
7. The apparatus of claim 6 , wherein the ones of the impression records including the watermark converted into views are of a same format as the impression records corresponding to the second media platform.
8. A method to generate audience metrics across different media platforms, comprising:
determining, using a processor, ones of impression records that include a watermark corresponding to a first media platform;
converting, using the processor, a first one of the impression records including the watermark to a converted impression record;
combining, using the processor, the converted impression record corresponding to the first media platform and a second impression record corresponding to a second media platform; and
generating, using the processor, audience measurement metrics based on the combined impression records.
9. The method of claim 8 , further including arranging the ones of the impression records including the watermark in a chronological order to identify adjacent ones of the impression records, the chronological order based on times the impression records were attributed to a panelist.
10. The method of claim 8 , further including determining a time period separating adjacent first and second ones of media access segments of the ones of the impression records including the watermark, the time period defined by an end time of the first one of the media access segments and a start time of the second one of the media access segments.
11. The method of claim 10 , wherein the time period defines a duration during which the media was not presented via the first media platform between the first one of the media access segments and the second one of the media access segments.
12. The method of claim 10 , further including determining if the time period exceeds a threshold, the threshold corresponding to a maximum duration between adjacent media access segments for the adjacent media access segments to be considered a part of a same media access session.
13. The method of claim 8 , further including converting the ones of the impression records including the watermark into views, the views determined based on a threshold corresponding to a maximum duration between adjacent media access segments.
14. The method of claim 13 , wherein the ones of the impression records including the watermark converted into views are of a same format as the impression records corresponding to the second media platform.
15. A non-transitory computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
determine ones of impression records that include a watermark corresponding to a first media platform;
convert a first one of the impression records including the watermark to a converted impression record;
combine the converted impression record corresponding to the first media platform and a second impression record corresponding to a second media platform; and
generate audience measurement metrics based on the combined impression records.
16. The non-transitory computer readable medium of claim 15 , wherein the instructions further cause the machine to arrange the ones of the impression records including the watermark in a chronological order to identify adjacent ones of the impression records, the chronological order based on times the impression records were attributed to a panelist.
17. The non-transitory computer readable medium of claim 15 , wherein the instructions further cause the machine to determine a time period separating adjacent first and second ones of media access segments of the ones of the impression records including the watermark, the time period defined by an end time of the first one of the media access segments and a start time of the second one of the media access segments.
18. The non-transitory computer readable medium of claim 17 , wherein the instructions further cause the machine to define the time period as a duration during which the media was not presented via the first media platform between the first one of the media access segments and the second one of the media access segments.
19. The non-transitory computer readable medium of claim 17 , wherein the instructions further cause the machine to determine if the time period exceeds a threshold, the threshold corresponding to a maximum duration between adjacent media access segments for the adjacent media access segments to be considered a part of a same media access session.
20. The non-transitory computer readable medium of claim 15 , wherein the instructions further cause the machine to convert the ones of the impression records including the watermark into views, the views determined based on a threshold corresponding to a maximum duration between adjacent media access segments.
