In Web Science, Social Media Based Epidemic Intelligence has emerged as a type of medical intelligence gathering that supports health ocials in routinely identifying potential health threats from more dynamic sources of information. State-of-the-art supervised approaches for SM-EI suer from the high costs associated with manually labeling training examples. This paper addresses the aforementioned problem by build- ing a self-supervised classier, one that labels its own train- ing examples. Our results show that a self-supervised classi- er, which discriminately selects its support vectors at each iteration achieves an F-measure of 78%. These results are comparable with existing, state-of-the-art systems, which rely exclusively on labeled data to build a classier.
