METHODS AND APPARATUS FOR OBTAINING VISUAL INSIGHT PROVENANCE OF A USER

摘要

Generally, methods and apparatus are provided for obtaining a user's insight provenance. A logical record of visual analytic activity of a user is maintained by recording one or more visual analytic actions. An exemplary method determines a set of action features of the one or more visual analytic actions; instantiates a data structure to record the action features; calculates a set of operations required to update the logical record based on the determined features; and updates the logical record based on the calculated operations. The visual analytic actions can optionally be classified using a predefined action taxonomy and by recording other action features. A plurality of the data structures can be associated with a node in a trail graph that represents one or more analytical paths of the user.
