Query: Detecting Ghostwriters in High Schools   Students hiring ghostwriters to write their assignments is an increasing
problem in educational institutions all over the world, with companies selling
these services as a product. In this work, we develop automatic techniques with
special focus on detecting such ghostwriting in high school assignments. This
is done by training deep neural networks on an unprecedented large amount of
data supplied by the Danish company MaCom, which covers 90% of Danish high
schools. We achieve an accuracy of 0.875 and a AUC score of 0.947 on an evenly
split data set.
