Google WIT Vietnamese
This data repos contain extracted data from Google WIT. The extracted data is all for Vietnamese language.
Given x is a data point in the OG dataset which has keys following OG field_name, the criteria to filter is
criteria = lambda x: x.get("language", "") == "vi" and x.get("caption_reference_description", "")
Text-related details
All .tsv.gz files follow OG data files in terms of file names and file structures.

Google Research has made sure that all sets don't share same exact images.

⚠ Please for the love of the gods, read this section carefully.
For all.index.fmt_id.image_url_list.tsv, from left to right, without headers, the columns are index, fmt_id, image_url. It is to map image_url (in all.image_url_list.txt) to fmt_id. It's for downloading images.
fmt_id is:
- used to name images (with proper image extensions) in
images/. indexbut filled with 6 zeros
Downloading time was less than 36 hours with:
- 90 Mbps
- Processor Intel(R) Core(TM) i7-8550U CPU @ 1.80GHz 1.99 GHz
- No asynchronous
For fail.index.fmt_id.status.image_url_list.tsv, from left to right, without headers, the columns are index, fmt_id, status, image_url. It is to track image urls (during downloading) that are inaccessible.
3367 image urls returned 404 (status values). In other words, we were able to download 97.88839275% of images.
images/ folder takes disk space of:
- 215 GBs (uncompressed)
- 209 GBs (compressed)
We use Pillow to open each image to make sure that downloaded images are usable. We also log all faulty files in corrupted_image_list.json. There are less than 70 image files.
For corrupted_image_list.json, for each item in this list, the keys are file_name, error. file_name is fmt_id with extension but without images/. Some errors are either:
- files exceed Pillow default limit
- files are truncated
To actually load those files, the following code can be used to change Pillow behavior
from PIL import Image, ImageFile
# For very big image files
Image.MAX_IMAGE_PIXELS = None
# For truncated image files
ImageFile.LOAD_TRUNCATED_IMAGES = True
