Abstract: [Purpose/significance] The multiple characteristics of data story can connect cognitive schema, solve users’cognitive disorder based on government open data, and improve the cognitive acuity and utilization rate of data. [Method/process] Through literature research, this paper summarizes the cognitive disorder of government open data amongusers, analyzes the internal causes of how the characteristics of data stories activate the cognitive schematic affiliation,clarifies the co-occurrence relationship and meaning construction process of cognitive schema under the effect of datastories, and constructs the schematic affiliation model by using system dynamics. [Conclusion/result] The storytellingbased on government open data has realized the transformation from cognitive disconnection to cognitive connection,which provides new ideas for the government to understand the public’s data cognitive needs, adopt data stories, promote and utilize data, and accelerate the efficiency of knowledge flow and transformation.
