    Abstract:We present an approach for selecting objectively
    informative and subjectively helpful annotations to social media
    posts. We draw on data from on an online environment where
    contributors annotate misinformation and simultaneously rate the
    contributions of others. Our algorithm uses a
    matrix-factorization (MF) based approach to identify annotations
    that appeal broadly across heterogeneous user groups - sometimes
    referred to as "bridging-based ranking." We pair these data with
    a survey experiment in which individuals are randomly assigned to
    see annotations to posts. We find that annotations selected by
    the algorithm improve key indicators compared with overall
    average and crowd-generated baselines. Further, when deployed on
    Twitter, people who saw annotations selected through this
    bridging-based approach were significantly less likely to reshare
    social media posts than those who did not see the annotations.
