SAPHIRE (Semantic and Probabilistic Heuristic Information Retrieval Environment) is an experimental computer program designed to test new techniques in automated information retrieval in the biomedical domain. A main feature of the program is a concept-finding algorithm that processes free text to find canonical concepts. The algorithm is designed to handle a wide variety of synonyms and convert them to canonical form. This allows natural language to be used for query input and also serves as the basis for a new approach to automatic indexing based on a combination of probabilistic and linguistic methods.
蓝宝石（语义和概率启发式信息检索环境）是一个实验性计算机程序，旨在测试生物医学领域自动信息检索中的新技术。该程序的一个主要特点是一种概念查找算法，它处理自由文本以找到规范概念。该算法旨在处理各种各样的同义词并将它们转换为规范形式。这使得自然语言可用于查询输入，并且还作为基于概率和语言方法相结合的自动索引新方法的基础。
