ColBERTer (Dim: 32) for Passage Retrieval

If you want to know more about our ColBERTer architecture check out our paper: https://arxiv.org/abs/2203.13088 🎉

For more information, source code, and a minimal usage example please visit: https://github.com/sebastian-hofstaetter/colberter

Limitations & Bias

• The model is only trained on english text.

• The model inherits social biases from both DistilBERT and MSMARCO.

• The model is only trained on relatively short passages of MSMARCO (avg. 60 words length), so it might struggle with longer text.
