| ##### The DivEMT Explorer is a tool to explore translations, edits and errors in the [DivEMT dataset](https://huggingface.co/datasets/GroNLP/divemt). | |
| The table below shows the 430 source sentences taken from Flores-101 and translated into six typologically diverse languages to build the DivEMT corpus. When you find a sentence you would like to inspect closely, insert its numeric id (between 0 and 429) in the box below, and select all the available languages you want to use for visualizing the results. | |
| Inside every language section, you will find the translations for all the available settings, alongside aligned edits and all collected metadata. You can filter the settings to see only cases you are interested in. In the **Attributions** section, you can find attribution maps computed using the [Inseq library](https://github.com/inseq-team/inseq) and the mBART model. | |
