Crowd mining

Proceedings of the 2013 ACM SIGMOD International Conference on Management of Data, 2013
Harnessing a crowd of Web users for data collection has recently become a wide-spread phenomenon. A key challenge is that the human knowledge forms an open world and it is thus difficult to know what kind of information we should be looking for. Classic databases have addressed this problem by data mining techniques that identify interesting data ...
