RedDust: a Large Reusable Dataset of Reddit User Traits

Social media is a rich source of assertions about personal attributes, such as ``I am a doctor'' or ``my hobby is playing tennis.'' Precisely identifying explicit assertions is difficult, though, because of the users' highly varied vocabulary and language expressions. Identifying implicit assertions like ``I've been at work treating patients all day'' is even more challenging. We present RedDust data resource consisting of personal attribute labels for over 300k Reddit users across five predicates: profession, hobby, family status, age, and gender. We construct RedDust using a diverse set of high-precision patterns To the best of our best knowledge, RedDust is the first semantic data resource about Reddit users at large scale. We envision further use cases of RedDust for providing background knowledge about user traits, to enhance personalized search and recommendation as well as conversational agents.
