受控词汇表的传统作用是将分散在多种自然语言术语中的项目集合在一起。因此,将其视为召回器械。当前在线结构系统的文件结构现在导致使用这样的词汇表作为精确设备。由于受控词汇表中的特定级别,对更广泛概念的搜索意味着可能有几个术语是无关紧要的。在这种情况下,检索系统的文件结构要求为了有效地搜索,入口点被分析并最小化。完全而不是部分输入受控术语似乎效率不高。
The traditional role of the controlled vocabulary has been to bring together items scattered by a multiplicity of natural language terms. Therefore, it was considered a recall device. The file structure of current online structure systems now leads to the use of such vocabularies as a precision device. Because of the levels of specificity in the controlled vocabulary, the search for broader concepts means several terms may be ncessary. In this case, the file structure of the retrieval systems requires that for efficient searching the entry points be analyzed and minimized. Complete, rather than partial, entry of controlled terms appears to be inefficient.
