Visual Analytics for Investigative Analysis and Exploration of Document Collections

Speaker: John Stasko , Georgia Institute of Technology
Date: September 11 2009
Time: 1:00PM to 2:00PM
Location: Grier A 34-401
Host: Rob Miller, MIT CSAIL

Making sense of data becomes more challenging as the data grows larger and becomes more complex. If a picture truly can be worth a thousand words, then clever visualizations of data should hold promise in helping people with sense-making tasks. In this talk, I will illustrate how interactive visualization and visual analytics can help people understand their data better. In particular, I will describe my research into visualization for supporting investigative analysis. This project explores how visual analytics can help investigators explore a large document collection in order to discover embedded stories and narratives scattered across the documents in the collection. My research group has developed a system named Jigsaw that assists investigators in such scenarios by providing interactive visual representations of the documents, the entities within the documents, and connections between them. I'll describe Jigsaw's design, visualizations, application to investigative scenarios, and its potential use in other document-centered sense-making tasks.
