The Newspaper Navigator Search Interface has launched!

Breaking news! You can now visit //news-navigator.labs.loc.gov/search  to interactively browse over 1.5 million historic photos from the Chronicling America database of digitized newspapers. Innovator in Residence Ben Lee built this application to give users with all levels of technical experience a simplified and dynamic way to explore the Newspaper Navigator dataset, which he created by using a machine learning algorithm to identify and extract all the visual content in Chronicling America.

Ben’s search application for Newspaper Navigator allows site visitors to search for images by visual similarity. First, visitors enter a keyword and select relevant photos from the search results based on what they’re looking for. This trains a machine learning algorithm, called an “AI Navigator,” which then searches through the collection of images again but this time identifies only those that are visually similar to the ones selected by the user.

As a result, visitors to the site can reverse image search by training their very own machine learning “classifier” on the fly. Don’t take our word for it–visit the Newspaper Navigator experiment page to try it out yourself!

Catch up on the Informal Virtual Audio Visual Summit

As you saw in last month’s newsletter, several units across the Library of Congress worked together to design and host an online conference for internal and external practitioners who work with audiovisual materials on September 15, 2020.

The event had over 400 attendees and over 30 speakers from all across the nation and world. In case you missed the impressive range of presentations, you can view the slides from all four thematic sessions (LC Share Out, Accessibility for All, A/V Makerspace, and Notes from the Field) on the LC Labs Event page: //labs.loc.gov/events/.

A captioned recording of the event will be available on this page in the coming weeks.
