Generative Information Retrieval Evaluation

no code implementations11 Apr 2024 Marwah Alaofi, Negar Arabzadeh, Charles L. A. Clarke, Mark Sanderson

We resolve this apparent circularity in two ways: 1) by viewing LLM-based assessment as a form of "slow search", where a slower IR system is used for evaluation and training of a faster production IR system; and 2) by recognizing a continuing need to ground evaluation in human assessment, even if the characteristics of that human assessment must change.

More Is Less: When Do Recommenders Underperform for Data-rich Users?

no code implementations15 Apr 2023 Yueqing Xuan, Kacper Sokol, Jeffrey Chan, Mark Sanderson

Users of recommender systems tend to differ in their level of interaction with these algorithms, which may affect the quality of recommendations they receive and lead to undesirable performance disparity.
