-A model for mapping abstract sentence descriptions to sentences that fit the descriptions. Trained on Wikipedia. Use ```load_finetuned_model``` to load the query and sentence encoder, and ```encode_batch()``` to encode a sentence with the model.
+A model for mapping abstract sentence descriptions to sentences that fit the descriptions, used in the preprint [Retrieving Texts based on Abstract Descriptions](https://arxiv.org/pdf/2305.12517.pdf). Trained on Wikipedia. Use ```load_finetuned_model``` to load the query and sentence encoder, and ```encode_batch()``` to encode a sentence with the model.

+**Note**: the method uses a dual encoder architecture. This is the **sentence encoder**; it should be used alongside the [**Query encoder**](https://huggingface.co/biu-nlp/abstract-sim-query).
