Abstract

Tattle is a civic tech project in India that is creating an archive of content circulated on WhatsApp and other chat apps, and building open source tools to navigate this archive. Such an archive is useful for research on information networks as well as for increasing the efficiency and reach of fact checking efforts. One of Tattle’s goals is opening the archive, even if in a limited scope, to the general public.
We will describe some of the challenges in data collection on encrypted platforms; and our approach for different kinds of search operations (duplicate, approximate, semantic) on multi-lingual and multi-media content. We will conclude with some of the ethical considerations in doing this work.
