Description
Since 1998, the number of countries publishing a public national security or defence document has risen from 1 to 125. This paper is part of a wider project to analyse a comprehensive corpus of these documents using an innovative methodology based on natural language processing technologies. This paper will (1) map the changing issues identified by countries in their top-level public security documents over the past 25 years, and (2) analyses the varied and changing conceptualisation of these issues as threats, risks, priorities, etc.
