These tools result in a visual model of the sense-making process, providing a way for analysts to visualize their analysis process, to reinterpret the problem, explore alternative paths, extract analysis patterns from existing history, and reuse them with other related analyses. Second, on this base, we build both a history view showing progress and alternative paths, and a dependency graph showing the underlying logic of the analysis and dependency relations among the results of each step. The latter allows analysts to edit analysis steps, and ultimately to program them.

In CzSaw’s approach to this, first, user interactions are translated into a script language that drives the underlying scripting-driven propagation system. Conventional history navigation tools range from basic undo and redo to branching timelines of user actions. This volume of the i2 Analyst’s Notebook 8 User Guide introduces you to some of the basic features of Analyst’s Notebook. To help analysts understand, explore, reference, and reuse their analysis process, we present a visual analytics system named CzSaw (See-Saw) that provides an editable and re-playable history navigation channel in addition to multiple visual representations of document collections and the entities within them (in a manner inspired by Jigsaw). Few visual analytics tools support this process well, nor do they provide support for visualizing and understanding the analysis process itself. In this process, analysts typically iterate through sequences of steps many times, varying parameters each time. This three-day course is designed for current i2 Analysts Notebook (ANB) users that have a desire to advance their skills in advanced search and discovery.

Visual analytics tools provide powerful visual representations in order to support the sense-making process.
