Pretraining with Contrastive Sentence Objectives Improves Discourse Performance of Language Models (2020.acl-main)
Copied to clipboard
| Challenge: | Recent models for unsupervised representation learning of text have put little focus on discourse-level representations. |
| Approach: | They propose an inter-sentence objective for pretraining language models that models discourse coherence and the distance between sentences. |
| Outcome: | The proposed model outperforms the BERT-Large model on the discourse representation benchmark DiscoEval and yields gains of 2%-6% absolute even for tasks that do not explicitly evaluate discourse. |
