随着“循证医学”的发展，临床指南的出现对于医生的临床实践活动具有重要的指导意义。临床指南可以适时准确地为医生的临床实践活动提供科学权威的诊疗建议，对于减小医生的误诊率，提高诊疗效率具有重要意义。目前临床指南的重要性得到医生的普遍认可，但是临床指南在实际临床实践活动中使用率很低。为了解决临床指南发展过程中遇到的瓶颈，提高临床指南的利用率，结合本体的方法将文本临床指南转变成临床指南知识库，具有非常重要的研究意义。以高血压临床指南为例，结合语义本体的方法构建高血压临床指南知识库。%As an authoritative medical reference material, clinical guideline is of prime importance in guiding clinical practice.
