【摘要】：[目的/意义]等级关系揭示了概念间的包含关系,不同深度的概念能够描述范围大小不同的主题,如何确定等级关系的层次深度,等级关系的层次遵循何种规律,成为知识组织系统的重要研究方向。[方法/过程]论文借鉴生态系统的能量流动规律,假设词族的等级结构符合生态系统能量流动的特点,并通过调研《汉语主题词表(工程技术卷)》的词族深度,发现词族等级关系深度与生态系统的营养级层次吻合,验证了等级关系生态属性的合理性。[结果/结论]等级关系遵循能量逐级递减的特性,且词族深度符合营养级3-5层的特征,等级关系的生态属性为叙词表等级关系的构建提供了新的思路。
[Abstract]:[purpose / meaning] hierarchical relationships reveal the inclusion relationships between concepts, concepts of different depths can describe topics with different ranges, how to determine the level depth of a hierarchical relationship, and what rules a hierarchy of hierarchical relationships follow. It has become an important research direction of knowledge organization system. [method / process] based on the rule of energy flow in ecosystem, the paper assumes that the hierarchical structure of word family accords with the characteristics of energy flow of ecosystem, and through investigating the depth of word family in < Chinese thematic Thesaurus (Engineering and Technology Volume) >, It was found that the depth of lexical hierarchical relationship coincided with the trophic level of ecosystem, which verified the rationality of ecological attributes of hierarchical relationships. [results / conclusion] the hierarchical relationship follows the characteristic of decreasing energy step by step, and the depth of the word family accords with the characteristics of the nutrition grade 3-5 layers. The ecological attribute of the hierarchical relationship provides a new way of thinking for the construction of the hierarchical relationship of the thesaurus.
