基于科学数据的用户相关性判断实证研究
An Empirical Study on User's Relevance Judgment Based on Scientific Data
摘要
Abstract
In order to explore the relationship among clues, criteria and perceived value in the process of scientific data relevance judgement and find the cognitive mechanism of user's relevance judgment in scientific data. This study measures the variables of clues, criteria and perceived value that affect scientific data relevance judgement. By investigating the participants who took part in"The Shared Cup"through questionnaire survey in China, this study obtains relevant data. The exploratory factor method is used to explore the clue set, the criteria set and the perceived value set. Based on the existing theoretical relationship between the clues, the criteria and the perceived value, and the relationship are verified by the method of structural equation modeling. The study finds the main clues, criteria and perceived value that affect theuser's relevance judgementin scientific data. Through the empirical analysis of the relationship between the cues, the criteria and the perceived value, the cognitive mechanism of the relevance judgment in the scientific data is explored.关键词
