| Abstract: | Purpose/significance] As a special way of information acquisition behavior, researching the mechanism of information encountering can provide theoretical reference for the internal and external environment design that effectively promotes information encountering among research users, and rich information behavior research.Method/process] This paper firstly analyzes the influencing factors model of information encountering under the process perspective, and then comprehends the causal relationship among factors affecting information encountering by means of system dynamics model. Also, this paper constructs the corresponding flow graph model, and explores the role of various influencing factors in the occurrence of information encountering through simulation analysis and quantitative form finally.Result/conclusion] The scientific researchers' information encountering system under the process perspective mainly consists of three subsystems:user, information and context. Among them, personality characteristics, information quality levels and behavioral contexts can significantly promote information encountering, while mission context significantly inhibits the occurrence of information encountering. |
