The first annual Dataverse Community Meeting June 9-11th was a success thanks to you, the Dataverse Community! Thank you to all who attended the meeting, presented, and participated in breakout sessions each afternoon. Read more about We are now a community!
At the beginning of next week, April 13th, Harvard Dataverse will be upgraded to Dataverse 4.0! The current version of the Harvard Dataverse (thedata.harvard.edu) will still be available for the next month for you to view. However, you will be able to edit, upload, or download in the new release 4.0 and can benefit from the new functionalities there. Read more about Dataverse 4.0, Next Week!
This presentation will provide some background information on the Dataverse's history, offer examples of how libraries and archives are using Dataverse to share data, and showcase the new features developed in version 4.0 for researchers.
Binary trees can be made differentially private by adding noise to every node and leaf. In such form they allow multifaceted exploration of a variable without revealing any individual information. While a differentially private binary tree can be used and read just like its conventional exact-valued analog, realizing that different combinations of nodes contain overlapping answers to the same information allows us to bring the statistical properties of multiple measurements under measurement error to noisy binary trees to create statistically efficient node estimates. We construct estimators that correctly use all available information in the tree, thus decreasing the error of nodes by up to eighty percent for the same level of privacy protection.
This article describes the novel open source tools for open data publication in open access journal workflows. This comprises a plugin for Open Journal Systems that supports a data submission, citation, review, and publication workflow; and an extension to the Dataverse system that provides a standard deposit API. We describe the function and design of these tools, provide examples of their use, and summarize their initial reception. We conclude by discussing future plans and potential impact.
