In January, Efe Okoro was awarded MSc Research. Efe’s thesis, ‘A study of different representation conventions during investigatory sensemaking’ explores the value of using different kinds of representational conventions for an intelligence analysis task. The study takes a particular interest in narrative, argumentation and freeform representations. Efe found that allowing users to structure information in freeform ways results in lower cognitive load. A post-hoc qualitative analysis resulted in Embedded Representational Structuring Theory (ERST), an approach which uses a finite set of conventions to characterise the structure of free-form user-generated representations.
