日本データベース学会のみなさま 早稲田大学の酒井と申します。NTCIR-17の新タスク（グループフェアネスを考慮したウェブ検索タスク） の参加募集第一弾をお送りいたします。ご検討いただければ幸いです。 * * * FIRST CALL FOR TASK PARTICIPATION: NTCIR-17 FairWeb-1 Task http://sakailab.com/fairweb1/ # Overview The FairWeb-1 task is a new English web search task that considers both relevance and group fairness. Each of our search topic seeks information about specific entity types: R (researher), M (movies), T (Twitter accounts), and Y (YouTube contents); accordingly, we have four topic types: R-topics (e.g., information retrieval researchers) M-topics (e.g., Daniel Craig 007 movies) T-topics (e.g., Twitter accounts that provide info on COVID) Y-topics (e.g., Coldplay covers on YouTube) For evaluating group fairness, we consider the following attribute sets containing either ordinal or nominal groups: R-topics: h-index (ordinal) AND gender (nominal) M-topics: #reviews on IMDb (ordinal) AND geographic region (nominal) T-topics: #followers (ordinal) Y-topics: #subscribers of the YouTube account (ordinal) For R- and M-topics, we will evaluate intersectional groupfairness. For example, for each R-topic, we want the search engine result page (SERP) to contain information about researchers with varying levels of h-index (not just high h-index people), AND with different genders (not just "men"). # Task input/ouput INPUT: - a search topic (R, M, T, or Y) - attribute set(s) and target distribution(s) OUTPUT: - a TREC-style run (a SERP for each topic) # Evaluation method We will use the Group Fairness and Relevance (GFR) framework: please visit our webpage for details. # Timeline October 7, 2022 Release of 1st CFP with sample topics and evaluation protocol December 16, 2022 Pilot relevance assessments for the sample topics and a few pilot runs released; topic set size determined Dec 19-Feb 28, 2023 Topic development March 1, 2023 Topics released; task registrations due May 12, 2023 Run submissions due May 15-July 31, 2023 Entity annotations; runs evaluated August 1, 2023 Evaluation results and draft overview released September 1, 2023 Draft participant papers due November 1, 2023 Camera ready papers due December 2023 NTCIR-17@NII, Tokyo, Japan # Inquiries: fairweb1org@list.waseda.jp # Organisers: Sijie Tao, Nuo Chen, Tetsuya Sakai (Waseda University, Japan) Zhumin Chu (Tsinghua University, P.R.C.)
