{"pk":27763,"title":"Shapes in Scatterplots: Comparing Human Visual Impressions and Computational Metrics","subtitle":null,"abstract":"We are currently in the process of designing and implement-\ning a computational cognitive system that combines percep-\ntion, memory, attention, and domain-specific semantic knowl-\nedge to perform data visualization tasks. While this work is\nstill in early stages, we report here on one subset of this larger\nproject that involves building a “visual long term memory” for\nthe system. To constrain the problem, we assume a domain\nof astronomy, and we focus exclusively on scatterplot visual-\nizations. In this paper, we present three of our initial steps\nalong this path. First, we collected and analyzed a catalog of\n74 scatterplots from real astronomy sources (papers, books,\netc.), which we consider to be typical data visualizations that\nastronomers would frequently encounter during their educa-\ntion. Second, we asked a team of human raters to rate all\n74 scatterplots along nine dimensions describing shape cate-\ngories, taken from a computational approach originally sug-\ngested by John and Paul Tukey called scagnostics. Third, we\ncalculated computer-based scagnostics for a subset of the scat-\nterplots. We measured inter-rater agreements among the hu-\nman raters and between the calculated and human ratings.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Astronomy"},{"word":"data visualization"},{"word":"Scagnostics"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/6xb4t9cr","frozenauthors":[{"first_name":"Josseph","middle_name":"","last_name":"Eilbert","name_suffix":"","institution":"Vanderbilt University","department":""},{"first_name":"Zameese","middle_name":"","last_name":"Peters","name_suffix":"","institution":"Vanderbilt University; Norfolk State University","department":""},{"first_name":"Fernanda","middle_name":"Monteiro","last_name":"Eliott","name_suffix":"","institution":"Vanderbilt University","department":""},{"first_name":"Keivan","middle_name":"","last_name":"Stassun","name_suffix":"","institution":"Vanderbilt University","department":""},{"first_name":"Maithilee","middle_name":"","last_name":"Kunda","name_suffix":"","institution":"Vanderbilt University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27763/galley/17403/download/"}]}
