| Challenge: | Using a pointer-generator framework for reading/sampling over large documents, we propose a framework for learning over long narratives where documents easily span over thousands of tokens. |
| Approach: | They propose a curriculum learning (CL) based pointer-generator framework for reading/sampling over large documents, enabling diverse training of the neural model based on the notion of alternating contextual difficulty. |
| Outcome: | The proposed framework improves on the NarrativeQA reading comprehension benchmark and reaches state-of-the-art performance. |

| Challenge: | Existing techniques for relevance and semantic matching cannot be easily adapted to the other. |
| Approach: | They propose a model that incorporates a hybrid encoder module, a relevance matching module and co-attention mechanisms that capture context-aware semantic relatedness. |
| Outcome: | The proposed model incorporates a hybrid encoder module, a relevance matching module and co-attention mechanisms that capture context-aware semantic relatedness. |

| Challenge: | Differentiable Search Indices (DSIs) encode a corpus of documents and use the same model to map queries directly to relevant document identifiers. |
| Approach: | They propose a continual learning challenge for Differentiable Search Indices (DSIs) they propose to continuously index new documents while answering queries related to previously and newly indexed documents. |
| Outcome: | The proposed model stably memorizes more documents and improves the average Hits@10 by +21.1% over baselines. |
