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.
