Following discussion with several expert backers, we’re proposing the following labels for ground truth on Places Visited, Contact Relationships, and Sedentary Activities. If you have any feedback, please share it in the comments section or send directly to us at organizers@crowdsignals.io
Places Visited
The data on places visited captures a user’s mobility patterns using semantic place categories that do not include any absolute location coordinates. We’re using a relatively standard approach to extraction of significant places from location data (e.g., clustering WLAN, GPS, and GSM data over time). The resulting places are initially tied to a geographic location and one or more visit events that include arrival and departure times. CrowdSignals.io participants will review the (geographically pinned) places on a map and provide one of the following labels for each. The data received by CrowdSignals.io backers will include only place labels with no absolute location information.

| Personal | Home, Work, Friend’s house, Family member’s house |

Sedentary activity labels will be collected simply with a two-part lockscreen questionnaire: first, are you seated? Then if so, what are you doing? The second label may take on any of the following values:
| Sedentary Behaviors |
| Eating, In Transit, Hobby, Playing a Game, Reading, Socializing, Using Computer, Watching Television, Working |
