Arden Syntax for Medical Logic Module (MLM)1 was designed for writing and sharing task-specific health knowledge in 1989. Several researchers have developed frameworks to improve the sharability and adaptability of Arden Syntax MLMs, an issue known as "curly braces" problem. Karadimas et al proposed an Arden Syntax MLM-based decision support system that uses an object oriented model and the dynamic linking features of the Java platform.2 Peleg et al proposed creating a Guideline Expression Language (GEL) based on Arden Syntax's logic grammar.3 The New York Presbyterian Hospital (NYPH) has a collection of about 200 MLMs. In a process of adapting the current MLMs for an object-oriented event monitor, we identified two problems that may influence the "curly braces" one: (1) the query expressions within the curly braces of Arden Syntax used in our institution are cryptic to the physicians, institutional dependent and written ineffectively (unpublished results), and (2) the events are coded individually within a curly braces, resulting sometimes in a large number of events - up to 200.
医学逻辑模块（MLM）的阿登语法于1989年设计用于编写和共享特定任务的健康知识。几位研究人员已经开发出框架来提高阿登语法医学逻辑模块的可共享性和适应性，这一问题被称为“花括号”问题。卡拉迪马斯等人提出了一种基于阿登语法医学逻辑模块的决策支持系统，该系统使用面向对象模型和Java平台的动态链接特性。佩莱格等人提议基于阿登语法的逻辑语法创建一种指南表达式语言（GEL）。纽约长老会医院（NYPH）有大约200个医学逻辑模块的集合。在将当前的医学逻辑模块适配为面向对象事件监视器的过程中，我们发现了两个可能影响“花括号”问题的问题：（1）我们机构使用的阿登语法花括号内的查询表达式对医生来说晦涩难懂，依赖于机构且编写效率低下（未发表的结果），以及（2）事件在花括号内单独编码，有时会导致大量事件——多达200个。
