【摘要】：为探索科学数据用户相关性判断中线索、标准与感知价值关系,发现科学数据用户相关性判断的认知机理,本研究对影响科学数据用户相关性判断的线索、标准和感知价值因素进行测量,以问卷调查形式对"共享杯"参赛人员进行调研,获得相关数据。使用探索性因子对线索集、标准集和感知价值集进行探索性分析,基于线索、标准、感知价值间已有理论关系,通过结构方程方法对三者关系进行验证分析。研究发现,影响科学数据用户相关性判断的主要线索、标准和感知价值因素,通过对线索、标准和感知价值关系的实证分析,探究科学数据用户相关性判断的认知机理。
[Abstract]:In order to explore the relationship between scientific data users' relevance judgment, the relationship between standards and perceived value, and to find out the cognitive mechanism of scientific data user correlation judgment, this study has a significant impact on the scientific data user relevance judgment. The criteria and perceived value factors were measured, and the participants of the "shared cup" were investigated by questionnaire to obtain the relevant data. The exploratory factors were used to analyze the clue set, the standard set and the perceptual value set, based on the clue, the standard set and the perceptual value set. There is a theoretical relationship between standard and perceived value, and the structural equation method is used to verify and analyze the three relationships. The research finds that the main clues, standards and perceived value factors that affect the correlation judgment of scientific data users, through the clue, The empirical analysis of the relationship between standard and perceived value explores the cognitive mechanism of user relevance judgment in scientific data.
