Abstract
A computer-implemented system and method for populating clusters of documents is provided. A set of clusters is placed in a display in relation to a common origin. One of a plurality of unclustered documents in the display is selected and an angle θ of the document from the common origin is determined. An angle σ of the cluster relative to the common origin is computed for each cluster. A difference is determined between the document angle θ and one such cluster angle σ. A predetermined variance is applied to the difference. The document is placed into the cluster when the difference is less than the variance.
