CLIPS

An existing database for a protocol retrieval system constructed from individual protocol data extracted from 184,634 clinical trials and 13,210 frame structures of clinical trial protocols. The database contains a variety of semantic information that allows the filtering of protocols during the search operation. Based on the database, a web application called the clinical trial protocol database system (CLIPS) is developed. This system enables an interactive search by utilizing protocol elements. To enable an interactive search for combinations of protocol elements, CLIPS provides optional next element selection according to the previous element in the form of a connected tree.本数据集为一款用于协议检索系统的现有数据库，其构建数据源自从184634项临床试验以及13210个临床试验方案框架结构中提取的独立方案数据。该数据库包含多类语义信息，可在检索流程中对试验方案实现筛选。基于该数据库，研究人员开发了一款名为临床试验方案数据库系统（Clinical Trial Protocol Database System，CLIPS）的Web应用程序。该系统依托方案元素实现交互式检索功能。为支持方案元素组合的交互式检索，CLIPS以连通树的形式，根据已选定的前序元素提供可选的下一元素选择机制。
