Improving Factual Completeness and Consistency of Image-to-Text Radiology Report Generation (2021.naacl-main)
Copied to clipboard
| Challenge: | Existing report generation systems suffer from incomplete and inconsistent generation, despite achieving high performance on natural language metrics such as CIDEr and BLEU. |
| Approach: | They propose two new rewards that encourage the generation of factually complete and consistent radiology reports by using an existing semantic equivalence metric. |
| Outcome: | The proposed system significantly improves the F1 score of a clinical information extraction performance on two open radiology report datasets. |
Keeping Consistency of Sentence Generation and Document Classification with Multi-Task Learning (D19-1)
Copied to clipboard
| Challenge: | Existing automated generation of articles' characteristics is inconsistent if they are generated individually. |
| Approach: | They propose a multi-task learning model with a shared encoder and multiple decoders for each task. |
| Outcome: | The proposed model generates more consistent headlines, key phrases and categories . it outperforms baseline model on the ROUGE scores and generates fluent headlines . |
Harnessing Popularity in Social Media for Extractive Summarization of Online Conversations (D18-1)
Copied to clipboard
| Challenge: | Existing methods for summarizing online conversations require large amounts of training data. |
| Approach: | They propose a disjunctive model that computes the contribution of content and context separately. |
| Outcome: | The proposed model outperforms baseline models which use popularity as informativeness measure. |
Integrating Tree Structures and Graph Structures with Neural Networks to Classify Discussion Discourse Acts (C18-1)
Copied to clipboard
| Challenge: | Existing models that analyze textual contents and discussion structures require understanding of textual content and discussion structure. |
| Approach: | They propose a model that integrates discussion structures with neural networks to classify discourse acts. |
| Outcome: | The proposed model improves accuracy and FB1 score by 1.5% compared to the previous best model. |

| Challenge: | Knowledge graphs (KGs) are incomplete and miss some information. |
| Approach: | They propose to learn entity representations via a graph structure that uses Seen-entities, Unseen-Entities and words as nodes created from the descriptions of all entities. |
| Outcome: | The proposed method improves relation prediction for the entity pairs containing Unseen-entities. |
Identifying Implicit Quotes for Unsupervised Extractive Summarization of Conversations (2020.aacl-main)
Copied to clipboard
| Challenge: | Existing methods of unsupervised summarization are lacking. |
| Approach: | They propose an unsupervised unsupervised extractive neural summarization model that extracts quotes as summaries from conversational texts. |
| Outcome: | The proposed model can extract quoted sentences as summaries from two email and social media datasets. |

| Challenge: | Radiology report generation systems can reduce the workload of radiologists by automatically describing the findings in medical images. |
| Approach: | They propose a planning-based radiology report generation system that generates the overall structure of reports as “plans” prior to generating reports that are accurate and consistent in order. |
| Outcome: | The proposed system improves the content order score by 5.1 pt in time series critical scenarios and the clinical factual accuracy F-score by 9.1 p.t. in time-series irrelevant scenarios. |
