Sentence Transformer

Using the Sentence Transformer to I’m trying to use Sentence Transformer to infer causal relationships between documents.

If we can do this, we can extract the cause and symptoms of the incident from the report.

So, I wondered if NLI could be used for feature learning to extract causal information. I thought.

What is NLI?

Inference of the relationship between two sentences

• Forward
• Inverse
• Unrelated

The three relations are.

Apply to causal relationships

If we apply the three relationships of NLI to causality, the following patterns are possible.

. BERT is a model that can be powerfully applied to natural language processing tasks.

However, it does not do a good job of capturing sentence-wise features.

Some claim that sentence features appear in [ CLS\ ], but This paper](https://arxiv.org/abs/1908.10084) claims that it does not contain that much useful information for the task.

Sentence BERT is a model that extends BERT to be able to obtain features per sentence.

The following are the steps to create Sentence BERT in Japanese.
