- Relation Extraction task is one of the task of Korean Language Understanding Evaluation(KLUE) Benchmark.
- Relation extraction can be defined as multiclass classification task for relationship between subject entity and object entity.
- Classes are such as
no_relation,per:employee_of,org:founded_by... totaling 30 labels. - This repo contains custom fine-tuning method utilizing monologg's R-BERT Implementation.
- Custom punctuations with Pororo NER has been added to the dataset prior to the model's training.
- If you want to refer to the experimentation note such as punctuation method of the entity, please refer to the blog post
RBERT structure can also be used on Code Clone Detection Task and Natural Language Inference Task.
