The candidates appear over time. Each time one appears, it must be immediately selected or rejected---a decision that is made by a group of individuals through voting. Assume the voters use approval ballots, i.e., for each candidate they only specify whether they consider it acceptable or not. This setting can be seen as a voting variant of choosing k secretaries. Our contribution is twofold. (1) We assess to what extent the committees that are computed online can proportionally represent the voters. (2) If a prior probability over candidate approvals is available, we show how to compute committees with maximal expected score.<\/jats:p>","DOI":"10.24963\/ijcai.2022\/36","type":"proceedings-article","created":{"date-parts":[[2022,7,16]],"date-time":"2022-07-16T02:55:56Z","timestamp":1657940156000},"page":"251-257","source":"Crossref","is-referenced-by-count":1,"title":["Online Approval Committee Elections"],"prefix":"10.24963","author":[{"given":"Virginie","family":"Do","sequence":"first","affiliation":[{"name":"Universit\u00e9 Paris Dauphine, PSL, CNRS, LAMSADE, France"},{"name":"Meta AI Research"}]},{"given":"Matthieu","family":"Hervouin","sequence":"additional","affiliation":[{"name":"Universit\u00e9 Paris Dauphine, PSL, CNRS, LAMSADE, France"}]},{"given":"J\u00e9r\u00f4me","family":"Lang","sequence":"additional","affiliation":[{"name":"CNRS, Universit\u00e9 Paris Dauphine, PSL, LAMSADE, France"}]},{"given":"Piotr","family":"Skowron","sequence":"additional","affiliation":[{"name":"University of Warsaw, Poland"}]}],"member":"10584","event":{"number":"31","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"acronym":"IJCAI-2022","name":"Thirty-First International Joint Conference on Artificial Intelligence {IJCAI-22}","start":{"date-parts":[[2022,7,23]]},"theme":"Artificial Intelligence","location":"Vienna, Austria","end":{"date-parts":[[2022,7,29]]}},"container-title":["Proceedings of the Thirty-First International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2022,7,18]],"date-time":"2022-07-18T11:07:20Z","timestamp":1658142440000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2022\/36"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2022,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2022\/36","relation":{},"subject":[],"published":{"date-parts":[[2022,7]]}}}
