Train your model from scratch

Prepare word and aspect embeddings.

Train word2vec: python3 run.py --task word2vec

Run Kmeans: python3 run.py --task kmeans

Check Kmeans Keywords python3 run.py --task kmeans-keywords

Self-supervised Learning (Teacher Model)

SSCL Training python3 run.py --task sscl-train

Before validation, you need to perform aspect mapping. There is a file aspect_mapping.txt in nats_results. For general, please change nomap to none. Other aspects should use their names. Please check test.txt to validate the names.

SSCL validation python3 run.py --task sscl-validate

SSCL testing python3 run.py --task sscl-test

SSCL evaluate python3 run.py --task sscl-evaluate

SSCL teacher python3 run.py --task sscl-teacher

SSCL clean results python3 run.py --task sscl-clean

Student Model

SSCLS training python3 run.py --task student-train

SSCLS validation python3 run.py --task student-validate

SSCLS testing python3 run.py --task student-test

SSCLS testing python3 run.py --task student-evaluate

SSCLS clean python3 run.py --task student-clean
