Hy-NLI: a Hybrid System for Natural Language Inference

Hy-NLI is a hybrid system for NLI. It computes inference with a deep learning (DL) and a symbolic approach and then its hybrid component determines which of the two labels should be trusted for a given pair. For the DL approach, it currently uses the BERT (Devlin et al, 2018) model, which is further fine-tuned on the SICK (Marelli et al, 2014) corpus. The symbolic approach computes inference based on a version of Natural Logic (Valencia, 1991; MacCartney, 2009) and on the Graphical Knowledge Representation (Kalouli et Crouch, 2018). The hybrid classifier is an MLP trained model. Please find more details in our paper:

Note that Hy-NLI targets performance, rather than explainability. If you are interested in the explainability of our system, check out our demo on XplaiNLI
