Please join the Department of Human Centered Design & Engineering for the 2016 HCDE Seminar Series. Full series at hcde.uw.edu/seminar-series. One key design feature of User Generated Content (UGC) systems is that they leverage the diverse contributions of the participants. The interests of the users of the system and their content contributions are likely to be of interest to other users of the system. One of the key design challenges for UGC systems is that they are designed to leverage the contributions of the participants. This is a challenge because the content contributed by the current set of participants might not represent the interests of a potentially growing audience of new users. For many UGC system understanding how existing content reflects the interests and biases of the participants is a difficult problem. In this talk, Dr. McDonald will describe a method for assessing the representativeness of UGC content based on the existence of that content in a target exogenous source. He will illustrate the method with two case studies that investigate how well the English language Wikipedia addresses the content interests of four sample audiences: readers of men’s and women’s periodicals, and readers of political periodicals geared toward either liberal or conservative ideologies. Preliminary findings from each case study are used to demonstrate the method About David W. McDonald
