In Proc of the 25th international conference … WebIn this paper, we present an active learning method to select the most informative query-document pairs to be labeled for learning to rank. Our method relies on hierarchical clustering. Unlike tra-ditional active learning methods, our method is unsupervised and the selected training sets can be used to train di‡erent learning to rank models.
