在版标引情报检索语言的组配及其句法语义控制/戴维民//北京图书馆通讯/北京图书馆·—1987(4)·—21～24组配是情报检索语言句法研究的重要内容之一。根据不同标准,组配可以划分为先组和后组、字面组配和概念组配、二元组配和多元组配。组配常常会造成各种语义误差,如二义性、多义性、同形异构和虚假语义等。在国内外的标引和检索实践中,通常采用先组与后组结合、概念组配、引用次序、职符、关系符和联符等手段,来控制这种语义误差。
In the version of the indexing information retrieval language assembly and syntax and semantic control / David Weimin Beijing Library Communications / Beijing Library · -1987 (4) · -21 ~ 24 grouping is an important part of information retrieval language syntax research one. According to different standards, grouping can be divided into the first group and the latter group, the literal grouping and concept grouping, binary grouping and multiple grouping. Grouping often leads to various semantic errors, such as ambiguity, ambiguity, isomorphism and false semantics. In the practice of indexing and searching at home and abroad, this kind of semantic error is usually controlled by combination of the first group and the latter group, the concept grouping, the reference order, the official character, the relational character and the concatenation.
