Abstract

During extended sensemaking tasks people typically create external representations that integrate information and support their thinking. Understanding the variety, role and use of these is important for understanding sensemaking and how to support it effectively. We report a case-study of a large, document-based fraud investigation undertaken by a law firm. We focus on the construction and use of integrated representations in the form of chronologies. We show how these supported conjecture recording, focussing on time-periods, identifying gaps, identifying connections and reviewing interpretations. We use our findings to highlight limitations of a previous analysis of representations in sensemaking which regards this as schema definition and population. The findings also argue for search tools designed to identify date references in documents, for the support of ad-hoc event selections, and the support of linking between integrating representations and source documents.
