| Challenge: | a limited amount of data exists for human-human spoken dialogues for research and development . a dialogue comprehension system that extracts clinical information from spoken conversations is clinically useful . |
| Approach: | They propose a framework inspired by nurse-initiated clinical symptom monitoring conversations to construct a simulated human-human dialogue dataset. |
| Outcome: | The proposed system achieves more than 80% F1 on held-out test set from nurse-to-patient conversations. |
Analyzing Code Embeddings for Coding Clinical Narratives (2021.findings-acl)
Copied to clipboard
| Challenge: | Recent work on automated ICD coding learn mappings between low-dimensional representations of clinical text reports and codes. |
| Approach: | They propose novel neural networks for encoding medical codes based on textual, structural and statistical characteristics using a single deep learning baseline model. |
| Outcome: | The proposed methods improve the accuracy of medical codes based on their textual, structural and statistical characteristics. |
Joint Dialogue Topic Segmentation and Categorization: A Case Study on Clinical Spoken Conversations (2023.emnlp-industry)
Copied to clipboard
| Challenge: | Utilizing natural language processing in clinical conversations is effective to improve the efficiency of workflows for medical staff and patients. |
| Approach: | They propose a model for dialogue segmentation and topic categorization that integrates natural language processing techniques into a joint model. |
| Outcome: | The proposed model improves on follow-up calls for diabetes management and reduces computational complexity and cost. |
Uncertainty Modeling for Machine Comprehension Systems using Efficient Bayesian Neural Networks (2020.coling-industry)
Copied to clipboard
| Challenge: | Neural approaches have improved machine comprehension tasks, but models often operate as a black-box, resulting in lower interpretability. |
| Approach: | They propose a hybrid approach to quantify model uncertainty using Bayesian weight approximation and boost up inference speed by 80% relative to test time. |
| Outcome: | The proposed approach boosts inference speed by 80% relative to the previous approach and is applied to a clinical dialogue comprehension task. |
