临床问题通常很长很复杂，形式多样。我们建立了一个名为AskHERMES的临床问答系统，可以对复杂的临床问题进行稳健的语义分析，并输出以问题为中心的提取摘要作为答案。本文介绍了AskHERMES的系统架构和初步评估，该系统在问题分析、总结和答案呈现方面实现了创新的方法。该系统收录了五种资源：MEDLINE摘要、PubMed Central全文文章、医学文献、临床指南和Wikipedia文章。我们将AskHERMES系统与谷歌（谷歌和谷歌Scholar）和UpToDate系统进行了比较，并要求医生根据易用性、回答质量、花费的时间和总体性能对这三个系统进行评分。AskHERMES允许医生以最小的查询公式以自然的方式输入问题，并允许医生有效地在所有回答句子中导航，以快速满足他们的信息需求。相比之下，医生需要制定查询来搜索谷歌和UpToDate中的信息。AskHERMES系统的开发仍处于早期阶段，与谷歌或UpToDate相比，知识资源有限。然而，评估结果表明，AskHERMES的性能与其他系统相当。特别是，在回答复杂的临床问题时，它显示出超越谷歌和UpToDate系统的潜力。AskHERMES可以在http://www.AskHERMES.org上找到，它有可能帮助医生实践循证医学，提高病人护理的质量。
Clinical questions are often long and complex and take many forms. We have built a clinical question answering system named AskHERMES to perform robust semantic analysis on complex clinical questions and output question-focused extractive summaries as answers. This paper describes the system architecture and a preliminary evaluation of AskHERMES, which implements innovative approaches in question analysis, summarization, and answer presentation. Five types of resources were indexed in this system: MEDLINE abstracts, PubMed Central full-text articles, eMedicine documents, clinical guidelines and Wikipedia articles. We compared the AskHERMES system with Google (Google and Google Scholar) and UpToDate and asked physicians to score the three systems by ease of use, quality of answer, time spent, and overall performance. AskHERMES allows physicians to enter a question in a natural way with minimal query formulation and allows physicians to efficiently navigate among all the answer sentences to quickly meet their information needs. In contrast, physicians need to formulate queries to search for information in Google and UpToDate. The development of the AskHERMES system is still at an early stage, and the knowledge resource is limited compared with Google or UpToDate. Nevertheless, the evaluation results show that AskHERMES’ performance is comparable to the other systems. In particular, when answering complex clinical questions, it demonstrates the potential to outperform both Google and UpToDate systems. AskHERMES, available at http://www.AskHERMES.org, has the potential to help physicians practice evidence-based medicine and improve the quality of patient care.
