The first stage

LSTK is a two-stage framework. In the first stage, it aims at generating a set of soft triples for reasoning.

You can generate a set of soft triples by:

Path for code: src_nli

1. training a textual entailment model:

python main_nli.py [dataset]

2. Searching triples with corresponding texts:

python generate_triples_by_index.py [dataset]

3. If the dataset is in Chinese, please use:

python generate_triples_by_index_zh.py [dataset]

4. Appling the trained textual entailment model to generate soft triples:

python apply_model_nli.py [dataset]

After the above process, you can get three files (train/valid/test_triple_scores.txt) storing soft triples.

You can also directly download our processed soft triples:

The second stage

In the second stage, you can use the generated soft triples to train SOTA neural approximate rule-based models.
