Research Statement

As research datasets and analyses grow in complexity, data that could be valuable to other researchers and to support the integrity of published work remain undiscoverable across disciplines. These data are especially concentrated in the “Long Tail” of funded research (Heidorn, 2008) where curation resources and related expertise are often inaccessible. In the domain of astronomy, it is widely acknowledged that uncurated "dark data" exist, but the scope of the problem remains uncertain. Following expert feedback obtained through two workshops held in 2015 and 2016 for the “Astrolabe” project, my PhD dissertation research aims to define the properties of uncurated or at-risk astronomical data, and to identify strategies for locating potentially-useful data to be targeted for curation. This mixed-methods project will enhance our understanding of the nature and prevalence of astronomical dark data and characterize astronomy’s Long Tail by: 1) Conducting background research through content analysis, targeted interviews, participant observation, and workshops; 2) Developing heuristics for searching the astronomical literature for references to potentially uncurated or at-risk data by identifying statistically-significant attributes of publications and authors, and through text classification; and 3) Surveying authors of a sample of journal publications about data and research practices.
