Existing works on scientific document representation learning only leverage the title and abstract of the paper. We present COSAEMB, a model that learns representations from the full-text of 97402 scientific papers from the S2ORC dataset. We present a novel supervised contrastive training framework for long documents using triplet loss and margin gradation. Our framework can be used to learn representations of long documents with any existing encoder-only transformer model without retraining it from scratch. COSAEMB shows improved performance on information retrieval from the paper’s full-text in comparison to models trained only on paper titles and abstracts. We also evaluate COSAEMB on SCIREPEVAL and CSFCube benchmarks, showing comparable performance with existing state-of-the-art models.falseConference Paper283-29220240cpConference Proceeding
