Modeling Provenance and Understanding Reproducibility for OpenRefine Data Cleaning Workflows

Preparation of data sets for analysis is a critical component of research in many disciplines. Recording the steps taken to clean data sets is equally crucial if such research is to be transparent and results reproducible. OpenRefine is a tool for interactively cleaning data sets via a spreadsheet-like interface and for recording the sequence of operations carried out by the user. OpenRefine uses its operation history to provide an undo/redo capability that enables a user to revisit the state of the data set at any point in the data cleaning process. OpenRefine additionally allows the user to export sequences of recorded operations as recipes that can be applied later to different data sets. Although OpenRefine internally records details about every change made to a data set following data import, exported recipes do not include the initial data import step. Details related to parsing the original data files are not included. Moreover, exported recipes do not include any edits made manually to individual cells. Consequently, neither a single recipe, nor a set of recipes exported by OpenRefine, can in general represent an entire, end-to-end data preparation workflow. Here we report early results from an investigation into how the operation history recorded by OpenRefine can be used to (1) facilitate reproduction of complete, real-world data cleaning workflows; and (2) support queries and visualizations of the provenance of cleaned data sets for easy review.

Helping Science Succeed: The Librarian’s Role in Addressing the Reproducibility Crisis

Headlines and scholarly publications portray a crisis in biomedical and health sciences. In this webinar, you will learn what the crisis is and the vital role of librarians in addressing it. You will see how you can directly and immediately support reproducible and rigorous research using your expertise and your library services. You will explore reproducibility guidelines and recommendations and develop an action plan for engaging researchers and stakeholders at your institution. #MLAReproducibility Learning Outcomes By the end of this webinar, participants will be able to: describe the basic history of the “reproducibility crisis” and define reproducibility and replicability explain why librarians have a key role in addressing concerns about reproducibility, specifically in terms of the packaging of science explain 3-4 areas where librarians can immediately and directly support reproducible research through existing expertise and services start developing an action plan to engage researchers and stakeholders at their institution about how they will help address research reproducibility and rigor Audience Librarians who work with researchers; librarians who teach, conduct, or assist with evidence-synthesis or critical appraisal, and managers and directors who are interested in allocating resources toward supporting research rigor. No prior knowledge or skills required. Basic knowledge of scholarly research and publishing helpful. Recording ($) is available here:
