# Amazon ESCI/ESCI-S dataset

A combination of [Amazon ESCI](https://github.com/amazon-science/esci-data) and [ESCI-S](https://github.com/shuttie/esci-s) datasets in a JSON format. 
Used for fine-tuning bi- and cross-encoder models in the [Metarank](https://huggingface.co./metarank) project.

## Dataset format

The dataset is encoded in a JSON-line format, where each row is a single ranking event,
with all item metadata pre-joined. An example:
