Jigsaw is a visual analytics system that helps investigators understand large collections of text documents and spreadsheets. It combines text mining with a suite interactive visualizations of the analysis results and the documents’ text. The system acts like a visual index onto a document collection, highlighting connections between entities and facilitating more rapid understanding of their important relationships. Jigsaw helps analysts “put the pieces together” and link initially unconnected activities into a more coherent story across the documents. It has been used in areas such as journalism, academic research, consumer reviews, law enforcement, and intelligence analysis.
