The following execution scripts are constructed for toy category as in the paper.
python prepare_data.py --input data/toy/profile.csv --out data/toy --ratio_validation 0.2 --ratio_test 0.2
python train_efm.py --indir data/toy --epoch 1000 --out data/toy/efm
python train_mter.py --indir data/toy --epoch 100000 --out data/toy/mter
Execute the following command to prepare training data for this task
python prepare_opinion_contextualization_data.py --indir data/toy --efm_dir data/toy/efm --mter_dir data/toy/mter --out data/toy
Train ASC2V by the following command:
python train_asc2v.py --indir data/toy --gpu 0 --out data/toy/asc2v --context asc2v
For ASC2V with sentiment score from MTER model, executing the following command:
python train_asc2v.py --indir data/toy --gpu 0 --out data/toy/asc2v-mter --context asc2v-mter
python seer.py --input A10L9NQO44OLOU,B0044T2KBU,toy,toy --corpus_path data/toy/train.csv --strategy greedy-efm --preference_dir data/toy/efm --contextualizer_path data/toy/asc2v/model.params
or if you want to use the sentiments produced by MTER
python seer.py --input A10L9NQO44OLOU,B0044T2KBU,toy,toy --corpus_path data/toy/train.csv --strategy greedy-mter --preference_dir data/toy/mter --contextualizer_path data/toy/asc2v-mter/model.params
The above command generates an explanation for user A10L9NQO44OLOU, item B0044T2KBU, and the demanded aspects are toy,toy (2 sentences about aspect toy). This example is taken from the test dataset.
By default, we run SEER with greedy algorithm. SEER-ILP is provided and IBM ILOG CPLEX Optimization Studio must be ready to be able to proceed further. After setting up CPLEX, you can try SEER-ILP with argument --strategy ilp-efm (or --strategy ilp-mter).
To run the framework with other data, please modify the arguments accordingly.
