[目的/意义]以公共图书馆、博物馆、美术馆和群众艺术馆数字资源整合为例,探讨通过赋予受控词汇"身份",提高资源检索的效率的方法。[方法/过程]定义多维坐标系统空间面、主题坐标轴和坐标点;通过为词汇概念赋予标识符,建立概念与词汇的关联,按一定规则为词汇赋予"身份",以概念优选机制、关联数据技术与索引表构建作为其辅助。此外,通过解析用户检索词语义,构建语义标识符,并对概念标识符进行拆分、组合,利用测算标识符点距的方法建立语义标识符与概念标识符之间的映射关系,实现检索维度优选。[结果/结论]多维坐标系统的坐标关系模型以"面-线-点"的坐标关系处理层次为基础,以"概念定位-词汇定位-资源定位"的检索层次为依据,并结合优选、关联与索引,拆分、组合与点距等相关实现机制,通过量化方法来处理词汇关系,能够提高机器对词汇的理解。

[Purpose/significance] Taking digital resource integration of libraries, museums, art museums and mass art museums as examples, this paper discusses a way to improve retrieval efficiency by assigning the controlled vocabularies with their "identifiers".[Method/process] A coordinate system is defined, which consists of three parts: space surfaces,coordinate axes and coordinate points that represent different vocabulary concepts. Following certain regulations, the concepts are assigned "identifiers" to establish relationship between vocabularies. Meanwhile, the system is supported by the "concept optimization" mechanism, the data-linking technology and the index list construction mechanism. For search engine, words inputted by users are firstly assigned with semantic "identifiers", then the "identifiers" of concepts will be analyzed in parts, before the mapping relationship of the two identifiers is generated. With these processes, retrieval dimensionality optimization is achieved.[Result/conclusion] The coordinate relationship model of the multi-dimensional coordinate system is based on the hierarchical model of "plane-line-point", and is in accordance with the "concept locating, vocabulary locating, and resource locating" retrieval hierarchy. With the help of implementation mechanisms like optimization, association and indexing, split and merging, it processes the relationship of words numerically, and the understandability of vocabulary is enhanced.
