Fall 2021 All-Users Group Meeting:

The Making of Enslaved.org new-window-icon.png : LOD, Enslaved Ontology, and Wikibase
Seila Gonzalez Estrecha and Dean Rehberger, Matrix (the Center for Digital Humanities and Social Sciences at Michigan State University)

Oct. 28, 2021, 1-2pm Eastern (12-1pm Central), via Zoom - register now new-window-icon.png

The Enslaved.org project brings together multiple siloed datasets in a Wikibase representation of People, Places, and Events within the historical slave trade. A goal of this project is to develop a tool for scholars and the public to interact with this data to better understand the lives of enslaved Africans and their descendants. This talk addresses the solutions taken by Enslaved.org in order to represent space, event, and people information and various challenges, including the technology behind the project and the motive to use Wikibase. It also covers the influence of places to disambiguate people records and the ontology alignment between the Wikibase graph and the owl ontology developed for Enslaved.org.
