概念组配的应用实例及其分析

Application Cases of Concept Combination and Its Analysis

组配标引是在词表中选择两个及两个以上有形式逻辑关系的词,按照特定规则组成的一组标引词串,用以满足文献多层次、多途径检索的需要。概念组配是文献标引的关键环节。根据参与组配的主题词之间的逻辑关系,概念组配可分为交叉组配、限定组配和联结组配3种基本类型。在实际组配标引工作中,编目员应避免因对新词表不熟悉造成检索词语构成混乱,避免因主题概念转换错误造成粗标、漏标和错标,避免因未遵循专指性标引规则造成切题不当,减少组配标引失误。

Combination indexing is a word string consisted by two or more than two formal logical relationships from the vocabulary according to specific rules for meeting literature needs of multi-level and multi-channel retrieval.Concept combination is a key round of document indexing.According to logical relationship between combination keywords,there are three basic types of concept combination,such as chiasmata combination,limited combination and coupling combination.In the practical work of combination indexing,catalogers could avoid the confusion of retrieval terms caused by the unfamiliar new vocabulary,avoid coarse indexing,leakage indexing and wrong indexing caused by conversion errors of theme concepts,and avoid indexing off the point caused by failing to follow exclusive rules,and so on,in order to reduce inaccurate combination indexing.
