Multi Language Indexing & Retrieving Support? about ragatouille

the link you provide on jaColBERT not working

Oh good catch! Updated it, the proper link is here

What is the suggestion do you have if I want to training on new languge? can you share your experience? I hope you can write down some steps so I can follow. I'm happy to introduce ColBERT new language if I can sucessful train it

There's some information on the training in the technical report . Otherwise, it should be pretty straightforward to train a ColBERT using the utils in RAGatouille, since training JaColBERT is what led to writing the lib! The training utilities handle hard negative mining, etc... for you

I forgot to meantion, how long and how much cost did you spent to train it? If you doing on home device, what is your specs?

I was lucky to get some GPU credits, so trained it on 8 Nvidia L4 GPU for around ~10 hours. I'm pretty sure you could still get decent results with less data and weaker hardware!

Hey!

ColBERT is essentially just a family of models, the examples use the original ColBERTv2 which is English-only.

There's a lot of interest in multilingual models and I'm hoping to be able to make that happen eventually, and I know other people are also working on it. Supporting more languages with ColBERT models would be fantastic! I'll leave this issue open as Help Wanted!

As of right now, I'm aware of these models to support non-English languages:

• 🇯🇵 bclavie/JaColBERT (by myself, trained using a mix of ColBERTv1 and ColBERTv2 methods)
• 🇫🇷 antoinelouis/colbertv1-camembert-base-mmarcoFR
• 🇬🇧🇨🇳🇷🇺... Suraj Nair et al.'s family of models for some multilingual support (eng queries to multiple languages retrieval), but not fully compatible with the main ColBERT codebase which RAGatouille is based on(definitely interesting to merge in the future!)

the link you provide on jaColBERT not working:

The model is trained on the japanese split of MMARCO, augmented with hard negatives. The data, including the hard negatives, is available on huggingface datasets.

Hey!

I had a go at training ColBERT for the spanish language a few weeks ago, unfortunately I still haven't had time to properly evaluate it, but if anyone wants to try it, it can be found here:
