+This repo contains the \[emb\]-cross-encoder model -- the cross-encoder model 
+which scores a query-item pair using dot-product of the contextualized query and item embeddings after jointly encoding the query-item pair. 
+This model is used in the experiments for our EMNLP 2022 paper titled "[Efficient Nearest Neighbor Search for Cross-Encoder Models using Matrix Factorization](https://arxiv.org/pdf/2210.12579.pdf)". 
+
+See [paper](https://arxiv.org/pdf/2210.12579.pdf) and/or [code](https://github.com/iesl/anncur) for more details about the model.
