Abstract: A system and method are provided that overcome the previously described limitations of prior art systems. The computer system, in fact, uses a set of information objects to interface with heterogeneous information sources. Information objects can be combined to form tasks that can be added, deleted and modified without requiring any modifications to the underlying program. In addition, the computer system allows users to navigate through a task and automatically generates links to related tasks based on the contextual information in which each step in the task is performed. As a result, links to related tasks do not have to be defined ahead of time, but rather can be dynamically generated at run time. This is accomplished by associating a semantic type or multiple semantic types with the information generated during each step. This allows the system to present links to tasks that utilize the same semantic types generated during the previous step.

Abstract: A method of displaying heterogeneous information includes executing an application program to process one or more activities. Each activity has information nuggets and next step links, and each information nugget is extracted from one or more heterogeneous information sources. Also, each next step link is associated with one or more information nuggets. One of the activities is selected, and an information nugget of the selected activity is displayed in a first region of the graphical user interface. A next step link associated with the displayed information nugget is displayed in a second region of the graphical user interface.
