Abstract. The ever-growing datasets of user activity traces promise to
offer captivating insights into human phenomena. Yet, these datasets are
more than just an observational tool. The insights derived from them are
increasingly being used to drive policies, to shape products and services,
and for automated decision making. It is therefore important to understand
the limitations around their use, especially when they are used to tackle
significant societal challenges, such as humanitarian crises, climate change,
minority issues, hate speech, and health – social good applications that we
will be covering in this talk.
