Nonetheless, the behavior of such algorithm lacks transparency, motivating measurements, modeling and analysis in order to understand and improve its properties. In this paper, we propose a reproducible methodology encompassing measurements, an analytical model and a fairness-based News Feed design. The model leverages the versatility and analytical tractability of time-to-live (TTL) counters to capture the visibility and occupancy of publishers over a News Feed. Measurements are used to parameterize and to validate the expressive power of the proposed model. Then, we conduct a what-if analysis to assess the visibility and occupancy bias incurred by users against a baseline derived from the model. Our results indicate that a significant bias exists and it is more prominent at the top position of the News Feed. In addition, we find that the bias is non-negligible even for users that are deliberately set as neutral with respect to their political views, motivating the proposal of a novel and more transparent fairness-based News Feed design.<\/jats:p>","DOI":"10.1145\/3308897.3308928","type":"journal-article","created":{"date-parts":[[2019,1,28]],"date-time":"2019-01-28T14:01:39Z","timestamp":1548684099000},"page":"68-69","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":5,"title":["Fairness in Online Social Network Timelines"],"prefix":"10.1145","volume":"46","author":[{"given":"Eduardo","family":"Hargreaves","sequence":"first","affiliation":[{"name":"Federal University of Rio de Janeiro, Rio De Janeiro, Brazil"}]},{"given":"Claudio","family":"Agosti","sequence":"additional","affiliation":[{"name":"University of Amsterdam, Amsterdam, Netherlands"}]},{"given":"Daniel","family":"Menasche","sequence":"additional","affiliation":[{"name":"Federal University of Rio de Janeiro, Rio de Janeiro, Brazil"}]},{"given":"Giovanni","family":"Neglia","sequence":"additional","affiliation":[{"name":"Universit \u00b4e C'ote d'Azur, Sophia Antipolis, France"}]},{"given":"Alexandre","family":"Reiffers-Masson","sequence":"additional","affiliation":[{"name":"Indian Institute of Science, Bangalore, India"}]},{"given":"Eitan","family":"Altman","sequence":"additional","affiliation":[{"name":"Universit\u00b4e Cote d'Azur, Sophia Antipolis, France"}]}],"member":"320","published-online":{"date-parts":[[2019,1,25]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1126\/science.aaa1160"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/2187836.2187907"},{"key":"e_1_2_1_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/nature11421"},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/INFOCOM.2016.7524445"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1145\/2702123.2702556"},{"key":"e_1_2_1_6_1","unstructured":"E.
