This paper describes MetaIndex, an automatic indexing program that creates symbolic representations of documents for the purpose of document retrieval. MetaIndex uses a simple transition network parser to recognize a language that is derived from the set of main concepts in the Unified Medical Language System Metathesaurus (Meta-1). MetaIndex uses a hierarchy of medical concepts, also derived from Meta-1, to represent the content of documents. The goal of this approach is to improve document retrieval performance by better representation of documents. An evaluation method is described, and the performance of MetaIndex on the task of indexing the Slice of Life medical image collection is reported.
本文介绍了MetaIndex,这是一个自动索引程序,其目的是为文档检索创建文档的符号表示。MetaIndex使用一个简单的转移网络解析器来识别一种源自统一医学语言系统叙词表(Meta-1)中主要概念集的语言。MetaIndex使用同样源自Meta-1的医学概念层次结构来表示文档内容。这种方法的目标是通过更好地表示文档来提高文档检索性能。本文描述了一种评估方法,并报告了MetaIndex在对“生活片段”医学图像集进行索引任务时的性能。
