Visual Analytics for Investigative Analysis

Zhicheng Liu and John Stasko

This work addresses the challenges faced by investigative analysts
confronting collections of text documents such as case reports. One
key task for these analysts is to "connect the dots" and discover
threats or plots that may be embedded across the document collection,
but only hinted to by any individual document. We have developed a
visual analytics system named Jigsaw that helps investigators in such
scenarios by providing interactive visual representations of the
documents, the entities within the documents, and connections between
them. This talk will describe Jigsaw and illustrate how it is useful
in these types of situations.
