Open Domain Multi-document Summarization: A Comprehensive Study of Model Brittleness under Retrieval (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Multi-document summarization (MDS) assumes a set of topic-related documents is provided as input. |
| Approach: | They formalize the task and bootstrap it using existing datasets, retrievers and summarizers. |
| Outcome: | The proposed method reduces the sensitivity of summarizers to imperfect retrieval, but is highly sensitive to other errors. |
TOPICAL: TOPIC Pages AutomagicaLly (2024.naacl-demo)
Copied to clipboard
| Challenge: | Topic pages aggregate useful information about an entity or concept into a single concise article. |
| Approach: | They propose a web app that generates topic pages for biomedical entities on demand . they use large language models and retrieval-augmented generation to generate high-quality topics . |
| Outcome: | The proposed method is based on a human evaluation of 150 biomedical topics . it uses large language models and retrieval-augmented generation (RAG) |
DeCLUTR: Deep Contrastive Learning for Unsupervised Textual Representations (2021.acl-long)
Copied to clipboard
| Challenge: | Sentence embeddings are an important component of many natural language processing systems. |
| Approach: | They propose a self-supervised objective for learning universal sentence embeddings that does not require labelled training data. |
| Outcome: | The proposed approach closes the performance gap between unsupervised and supervised pretraining for universal sentence encoders. |
