# Dataset Card for "opus-medical-en-de"

This is a multi-domain German-English parallel data introduced in [Aharoni and Goldberg (2020)](https://aclanthology.org/2020.acl-main.692/). It is a new data split created that avoids duplicate examples and leakage from the train split to the dev/test splits. The original multi-domain data first appeared in [Koehn and Knowles (2017)](https://www.aclweb.org/anthology/W17-3204/) and consists of five datasets available in the [Opus website](http://opus.nlpl.eu/).
