Convolution window of 3 is passed over the text, which is used as input to an LSTM. The output of the LSTM is averaged over all timesteps and then a single value in the range of [0,1] is predicted as a scaled-down score for the essay. They evaluate by measuring quadratic weighted Kappa on the Kaggle essay scoring dataset.
