Datasets

Sanitized privacy/benefits preference factors dataset (Facebook usage) This dataset contains survey participants’ responses to three questions used to quantify the relative benefits of sharing/viewing location and co-location information on Facebook, and the associated relative costs in terms of location privacy. Specifically, we assessed the participants’ preferences regarding, respectively, (1) sharing vs. viewing posts with location information (i.e., check-in posts), (2) sharing posts with location information vs. sharing posts with colocation information, and (3) location privacy vs. benefits of sharing location information. We designed these survey questions by following a rigorous full-profile conjoint analysis approach. The datasets also contains general information about the participants’ Facebook general usage and location and co-location sharing on Facebook. The data was collected in early 2016, from 250 active Facebook users recruited via the Amazon Mechanical Turk platform, through an online survey. The survey participants were asked to rank by preference a number of scenarios in which posts were removed from Facebook (e.g., “two of your recent posts are kept and one of your friend’s recent posts is kept”, “none of your recent posts is kept and one of your friend’s recent posts is kept”). Preference factors can be extracted from the responses. Please e-mail alexandramihaela.olteanu@epfl.ch to obtain the dataset. The dataset is in the CSV File Format.
