An approach to curves in abelian surfaces using Fourier--Mukai and quadratic forms
Katrina Honigs, Graham McDonald, Peter M. McDonald
It was proven by Yoshioka that given a complex abelian surface of Picard rank whose primitive polarization is non-principal of type , there is an isomorphism $Ψ:\mat…
Explaining When PRF Fails: Participatory Auditing for Selective Query Expansion
Zeyan Liang, Graham McDonald, Iadh Ounis
Pseudo-Relevance Feedback (PRF) improves retrieval effectiveness on average, but harms a substantial fraction of queries through query drift, an asymmetry hidden by aggregate offli…
Document Similarity Enhanced IPS Estimation for Unbiased Learning to Rank
Zeyan Liang, Graham McDonald, Iadh Ounis
Learning to Rank (LTR) models learn from historical user interactions, such as user clicks. However, there is an inherent bias in the clicks of users due to position bias, i.e., us…
Quantifying Query Fairness Under Unawareness
Thomas Jaenich, Alejandro Moreo, Alessandro Fabris +4
Traditional ranking algorithms are designed to retrieve the most relevant items for a user's query, but they often inherit biases from data that can unfairly disadvantage vulnerabl…
Query Exposure Prediction for Groups of Documents in Rankings
Thomas Jaenich, Graham McDonald, Iadh Ounis
The main objective of an Information Retrieval system is to provide a user with the most relevant documents to the user's query. To do this, modern IR systems typically deploy a re…
Theta characteristics and the fixed locus of [-1] on some varieties of Kummer type
Katrina Honigs, Graham McDonald
We study some combinatorial aspects of the fixed loci of symplectic involutions acting on hyperkähler varieties of Kummer type. Given an abelian surface with a -polariza…
Overview of the TREC 2022 Fair Ranking Track
Michael D. Ekstrand, Graham McDonald, Amifa Raj +1
The TREC Fair Ranking Track aims to provide a platform for participants to develop and evaluate novel retrieval algorithms that can provide a fair exposure to a mixture of demograp…
The FACTS of Technology-Assisted Sensitivity Review
Graham McDonald, Craig Macdonald, Iadh Ounis
At least ninety countries implement Freedom of Information laws that state that government documents must be made freely available, or opened, to the public. However, many governme…
