Open source intelligence (OSINT) refers to information that is collected, identified, refined, and utilized from any publicly available sources to meet intelligence needs. With the advent of the internet, particularly the widespread use of social media, OSINT information in many fields is distributed across various online platforms, fundamentally altering its value, status, and impact. Generally, OSINT has characteristics such as low value density (a small proportion of valuable intelligence relative to total data), frequent spatiotemporal evolution (the content and connections of the information can change over time), and complex multidimensional relationships (intelligence and its related information can be embedded in any dimension and appear in any form).
