Neural Essay Assessor: An Automated Essay Scoring System Based on Deep Neural Networks

Neural Essay Assessor

An automatic essay scoring system based on convolutional and recurrent neural networks, including GRU and LSTM.

Set Up

• Install Keras (with Theano backend)
• Prepare data
• Run train_nea.py

Data

We have used 5-fold cross validation on ASAP dataset to evaluate our system. This dataset (training_set_rel3.tsv) can be downloaded from here. After downloading the file, put it in the data directory and create training, development and test data using preprocess_asap.py script:

cd data
python preprocess_asap.py -i training_set_rel3.tsv

Options

You can see the list of available options by running:

python train_nea.py -h

Example

The following command trains a model for prompt 1 in the ASAP dataset, using the training and development data from fold 0 and evaluates it.

THEANO_FLAGS="device=gpu0,floatX=float32" python train_nea.py
	-tr data/fold_0/train.tsv
	-tu data/fold_0/dev.tsv
	-ts data/fold_0/test.tsv
	-p 1	# Prompt ID
	--emb embeddings.w2v.txt
	-o output_dir
