Abstract: A plane figure presents statistics relating to data items. The plane figure includes multiple wedges which categorize a set of data items into base subsets of data items. A ring with a ring radius is displayed, and the ring radius represents a measure for at least one base subset. A corresponding wedge has a wedge radius which differs from the ring radius in proportion to a difference between the measure for that base subset and a measure for a subsidiary subset of that base subset. For example, the subsidiary subset may relate to data items for a predetermined timeframe. Boundaries, such as dividing lines, may be displayed within one or more wedges to define areas that represent additional subsets of data items. In another embodiment, a presentation space include first, second, and third groups of objects, with lines displayed between certain objects to represent flows of information between those objects.

Abstract: A program product characterizes a set of information to determine common characteristics among subsets of the set of information. The program product includes computer instructions which obtain characteristic data that describe characteristics of an entity. For example, the characteristic data may include titles of individuals within an organization. The computer instructions also obtain a set of information associated with the entity (e.g. a set of e-mail messages, Web pages, business memoranda, etc.) The computer instructions identify key terms within the set of information and classify the set of information into at least first and second subsets. In addition, the computer instructions characterize the first subset as more important than the second subset, based on the key terms and the characteristic data. For example, a subset of documents associated with officers of a company may be characterized as more important than a subset of documents associated with temporary employees.
