Enslaved.org: A knowledge representation in WikiBase of people, events and places in the historical slave trade

11:30 a.m. Tuesday, November 10, 2020 | Zoom*


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. The vague definitions for places, with limited geographical information, presents challenges for this project including identifying the best approaches to represent the data. In this context, the meaning of place does not only include the concept of space but also the ethno-identity of many of those who were enslaved. 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.
