1/ With @LC_Labs, #NDNP, and @dsweld, I’m excited to share the Newspaper Navigator search app: train your own AI navigators to search over 1.5 million historic newspaper photos by visual similarity! (desktop viewing recommended) #ChronAm

2/ For the first phase of my @librarycongress Innovator in Residence project, I created the #NewspaperNavigator dataset: extracted visual content from 16+ million newspaper pages in #ChronAm. This search app provides new ways of searching the dataset.

3/ In addition to supporting keyword search, the Newspaper Navigator app leverages image embeddings to support on-the-fly training and re-training of AI navigators in just a couple of seconds. Here is an example of training an AI navigator to retrieve photos of sailboats: A screenshot of an AI navigator trained to retrieve images o
4/ As with the Newspaper Navigator dataset and #ChronAm, the full search app is in the public domain, from the photos to the code. You can find all code for Newspaper Navigator at this GitHub repo: github.com/LibraryOfCongr…
5/ Because machine learning has a fraught history with perpetuating marginalization, I wrote a data archaeology investigating the ways in which machine learning mediates our interactions with the visual content in the Newspaper Navigator dataset and app.

6/ In the data archaeology, I study the digitization journeys of 4 reproductions of the same photo of W.E.B. Du Bois, as found in the pages of 3 Black newspapers in #ChronAm.
7/ This afternoon, I’m presenting with the amazing scholars @SarahHSalter @jimcasey1 and @jgob at the public #NDNP panel discussion “Seeing Editors: Metadata, Machine Learning, and the Shapes of Social Justice"! @NEH_PresAccess

9/ I want to thank @LC_Labs, #NDNP, @librarycongress, @NEH_PresAccess, and my Ph.D. advisor @dsweld @uwcse for collaborating with me on #NewspaperNavigator and making the project possible!
10/ Lastly, please feel free to reach out to me on Twitter or by email with any questions about #NewspaperNavigator!
