On domain similarity and effectiveness of adapting-to-rank
Keke Chen, Jing Bai, Srihari Reddy, Belle L. Tseng · 2009
Adapting to rank address the problem of insufficient domain-specific labeled training data in learning to rank. However, the initial study shows that adaptation is not always effective. In this paper, we investigate the relationship between the domain similarity and the effectiveness of domain adaptation with the help of two domain similarity measure: relevance correlation and sample distribution correlation.
