This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2).Getting a comprehensive answer to a medical question from Web search engines can be time-consuming because health information, as is common on the Web, is scattered across many websites. One difficulty is the prevalent vocabulary mismatch between different sources due to synonymous words, morphological variations, abbreviations, and different word orderings. Another challenge is that, for those who are not medical experts, health information can be complex and difficult to comprehend. Supportive visual representations can be helpful to various people, for example, those reading text not in their first language, older adults, or more generally, non-experts. To address these challenges, this project brings together health information in a single unified place by assimilating, synthesizing, and storing health information in a broad-coverage resource with a shared vocabulary. Such a resource serves the purpose of facilitating fast access to comprehensive answers to health questions to save people time who otherwise might need to spend a substantial amount of time reading different sources to connect the dots and get a complete answer to their information need. To help people understand complex health information, the project will generate summaries that combine text and supportive visualizations.This project will develop novel techniques for integrating information from disparate sources. This entails identifying relevant content and reconciling the mismatch in the vocabularies of different sources. To enforce a shared vocabulary across sources, the project will develop novel techniques for entity linking, that are not limited to recognizing entities seen at training time, as new diseases, treatments, other types of medical entities can emerge. For broad coverage, the project will consider content written by clinicians, researchers, and consumers. The project will convert this information into a graph structure that can be used to learn representations that further enhance coverage of the resource while maintaining high precision. The project will also develop novel techniques for multimodal summaries of healthcare answers to facilitate understanding of complex concepts.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项的全部或部分资金来源于《2021 年美国救援计划法案》（公法 117-2）。从网络搜索引擎获取医疗问题的全面答案可能非常耗时，因为健康信息（如网络上常见的那样）分散在许多网站上。困难之一是由于同义词、形态变化、缩写和不同的词序而导致不同来源之间普遍存在的词汇不匹配。另一个挑战是，对于非医学专家来说，健康信息可能很复杂且难以理解。支持性视觉表示对各种人都有帮助，例如，那些阅读非母语文本的人、老年人，或者更一般地说，非专家。为了应对这些挑战，该项目通过同化、合成和存储具有共享词汇的广泛覆盖资源中的健康信息，将健康信息汇集在一个统一的位置。此类资源的目的是促进快速获得健康问题的全面答案，以节省人们的时间，否则他们可能需要花费大量时间阅读不同的来源来连接各个点并获得其信息需求的完整答案。为了帮助人们理解复杂的健康信息，该项目将生成结合文本和支持性可视化的摘要。该项目将开发整合不同来源信息的新技术。这需要识别相关内容并协调不同来源词汇的不匹配。为了强制跨来源共享词汇表，该项目将开发用于实体链接的新技术，这些技术不仅限于识别训练时看到的实体，因为新的疾病、治疗方法和其他类型的医疗实体可能会出现。为了扩大覆盖范围，该项目将考虑临床医生、研究人员和消费者撰写的内容。该项目将把这些信息转换成图形结构，可用于学习表示，进一步增强资源的覆盖范围，同时保持高精度。该项目还将开发医疗保健答案多模式摘要的新技术，以促进对复杂概念的理解。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
