Learning Rich Representation of Keyphrases from Text (2022.findings-naacl)
Copied to clipboard
| Challenge: | Prior work has referred to extractive (part of document) or abstractive (not part of document). |
| Approach: | They propose to use a new pre-training objective to introduce keyphrases into transformer language models in discriminative and generative settings. |
| Outcome: | The proposed model improves performance in discriminative and generative settings and also improves on named entity recognition, question answering, relation extraction and abstractive summarization tasks. |
Generating Fine-Grained Open Vocabulary Entity Type Descriptions (P18-1)
Copied to clipboard
| Challenge: | Fig. 1 shows an example of a concise entity description presented to a user. |
| Approach: | They propose a dynamic memory-based network that generates a short open vocabulary description of an entity by leveraging induced fact embeddings and dynamic context. |
| Outcome: | The proposed network generates a short open vocabulary description of an entity . it can discern relevant information for more accurate generation of type description . |
Unsupervised Contrast-Consistent Ranking with Language Models (2024.eacl-long)
Copied to clipboard
| Challenge: | Language models contain ranking-based knowledge and are powerful solvers of in-context ranking tasks. |
| Approach: | They propose to use a model to elicit language models' ranking knowledge without supervision by using a pairwise, pointwise and listwise prompting method. |
| Outcome: | The proposed method is inspired by an unsupervised probing method called Contrast-Consistent Search (CCS). |

| Challenge: | Prior work on salient entity detection focused on machine learning models that require heavy feature engineering. |
| Approach: | They propose to fine-tune medium-sized language models with a cross-encoder style architecture to achieve significant performance gains over feature engineering approaches. |
| Outcome: | The proposed model fine-tunes medium-sized pre-trained language models with a cross-encoder style architecture yields substantial performance gains over feature engineering approaches. |
