System for evaluating an information aggregate includes a metrics database for storing document indicia including document attributes, associated persons and time-stamped tracked activities; a query engine responsive to a user request and the metrics database for aggregating documents having same, unique attributes in an information aggregate; the query engine further for calculating recency value of the aggregate; and a visualization engine for visualizing recency values for a plurality of aggregates at a client display. Base recency, relative recency, cross-aggregate recency, and normalized cross-aggregate recency metrics are provided.
