Multi30k Data Repository

Getting ready

Along with the data files, we also provide:

• subword-nmt as a GIT submodule
• A recent (December 2017) snapshot of Moses preprocessing scripts

under scripts/ in order to minimize processing differences across the users.

In order to fetch everything correctly, you need to clone the repository with --recursive flag:

$ git clone --recursive https://github.com/multi30k/dataset.git multi30k-dataset

Visual features

Pre-extracted visual features can be downloaded from Google Drive and the raw images can be requested here.

Task 1

• Raw files under data/task1/raw
• Tokenized files under data/task1/tok. These files were produced with the preprocessing script scripts/task1-tokenize.sh.
