Altmetric Attention ScoreIndicator of the amount of attention a reseacht output has received regardless its quality. The score is determined by an automated algorithm which takes into account three factors: volume (number of mentions), source (quality of the source of the mentions, e.g. an average newspaper posting will have a higher weighting that an average tweet), and author (the author of the mention changes the weighting given to each mention, i.e. someone who is considered an influencer within a community will receive a higher weighting that someone who is not)030,25
