[目的/意義]情報研究對情報感知不斷增長的要求,促進了系統科學探討情報感知方法和模式的進程。[方法/過程]文章解析了錢學森提出的系統辨識方法,找出其支持情報感知的依據,并在系統辨識理念的指導下,解讀了情報感知的過程和人機交互的情報感知模式。[結果/結論]分析發現第四范式下的情報感知是人機交互的一個過程,其核心就是情報人員在面對"海量、嘈雜和不確定"的數據時,基于系統辨識理念,綜合運用人類感知能力和機器感知技術,構建起系統辨識模型,準確、理性、快速地識別和解釋模糊數據之間關系,完成判讀情報的任務。

[Purpose/significance] The increasing demand for information awareness in intelligence research has promoted the systematic and scientific study process of the methods and patterns of information awareness.[Method/process] This paper analyzes the system identification method proposed by Qian Xuesen,finds out the basis for information awareness support,and under the guidance of system identification theory,studies the information awareness process and information awareness modes of human-computer interaction.[Result/conclusion] The information awareness under the fourth paradigm is a process of human-computer interaction.Its core is that when the intelligence personnel face the "massive,noisy and uncertain" data,they will comprehensively use human awareness ability and machine awareness technology based on system identification theory,and build the system identification model,in order to accurately,rationally and quickly identify and interpret the relationship between fuzzy data,and to complete the task of interpreting information.
