文章在扎根理论思想指导下,运用案例研究方法,以英、美等发达国家的情报、安全、执法、商业诸领域的政府和私营机构为分析单位,以规范的定性研究程序进行数据处理和模型构建。整个过程分为3个阶段:原型构建、模型精炼和模型验证与确立。最终,得出以7个核心范畴为支撑的公开源情报理论模型:效用、情境信息、沟通协作、分析、聚焦、应变能力、交叉检验。 Under the guidance of grounded theory, the article uses the case study method to take the government and the private sector in the intelligence, security, law enforcement and commercial fields in the developed countries such as Britain and the United States as the analysis units and conducts the data processing and the model with the standardized qualitative research procedure Construct. The whole process is divided into three stages: prototype building, model refining and model validation and establishment. Finally, we get the theoretical model of open source intelligence supported by seven core categories: utility, contextual information, communication and collaboration, analysis, focusing, adaptability and cross-checking.
