Researchers have developed "Ranking Companion," a novel visual analytics system designed to improve the creation of personalized item rankings. This approach addresses the challenge of users lacking domain knowledge or the ability to articulate specific preferences by allowing them to express preferences through judgments on known items. Ranking Companion integrates six different item-selection methods, combining model-driven active learning with human-driven selection to offer users greater flexibility and control. A user study with 10 participants indicated trade-offs in perceived ranking quality across accuracy, diversity, novelty, transparency, control, and satisfaction when using these hybrid methods. AI
