Social media and before them the Web have democratized the production and
dissemination of information, ushering us into a new era of civic engagement and
innovation at a global scale. However, a number of worrisome trends threaten
the foundations of these public information spaces. Misinformation boosted by
automated amplifiers (i.e., social bots) is an obvious example, but we are also
witnessing to the rise of other negative `malinformation' trends, such as
harassment, hate speech, and gender inequality. In this talk I will describe my
contributions to understanding what is threatening the integrity of the digital
public sphere, and reducing universal access to it. I will first talk about
tracking the diffusion of digital misinformation and the manipulation
strategies employed by social bots on Twitter. I will then describe one of the
first large-scale, systematic studies of gender inequality and objectification
in the social gaming platform Twitch. Finally, on the side of possible
countermeasures to the spread of false information, I will describe a novel
approach to mining knowledge networks like Wikipedia to perform fact-checking.
These methods could find potential application in the newsroom, where new data
science tools are desperately needed by journalists to cope with the massive
volume of unstructured information that needs to be checked. I will conclude
describing an agenda of future research, and discuss what external funding
bodies are most interested in this type of work.
