Contract NLI model

The new model is based on Flan T5 (LLM model released by Google) and finetuned on the Stanford Contract NLI dataset. This model can apply Natural Language Inference (NLI) in legal contracts, meaning that it can classify whether a hypothesis is an entailment, contradiction or neutral (not related to or not clear) to the premise (context).

See the following examples:

  • Not clear if hypothesis is related to premise:
  • Contradiction:
  • Entailment:

New demo apps

We release new demo apps for Question Answering and for Summarization, showing examples using the latest models of the library.

  • New Flan T5 based model for Question Answering:
  • New Flan T5 based model for Summarization:

Showing the capabilities of the pretrained models can help practitioners understand how to use Legal NLP for their specific use cases.
