Abstract
A program for matching between controlled medical vocabularies has been developed which adopts methods used in the domain of Information Retrieval. This program combines a stemmer based on fragments of words (digrams) with a similarity function. The proposed stemmer did not require any knowledge about word-formation rules and helped the identification of several kinds of word variants. The adopted similarity function assigned the highest score to the best candidate match in 99.0% of the cases.
摘要
已开发出一种用于受控医学词汇匹配的程序，该程序采用了信息检索领域中使用的方法。此程序将基于单词片段（双字母组）的词干提取器与相似性函数相结合。所提出的词干提取器不需要任何关于构词规则的知识，并有助于识别多种单词变体。所采用的相似性函数在99.0%的情况下将最高分赋予最佳候选匹配项。
