Abstract: An interface for a database. The database contains information about subnets in a large network, such as the Internet. The interface displays the information in a hierarchical fashion. However, because all subnets cannot be displayed on a display at once, some subnets are displayed, and a user reaches other subnets by calling for subsets of the subnets displayed.

Abstract: A system or method (collectively “system”) for gathering and utilizing information. The system can identify, gather, and manage information in an automated fashion without human intervention and in accordance with user-defined processing rules (“rules”). Communications, documents, and other forms of information embodied in a retrievable format (collectively “files”) can be stored in a depository that is accessible by a search tool. The search tool uses a search parameter to identify one or more interesting files amongst all of the files in the depository. Search parameters can be created in accordance with rules relating to particular objectives. For example, in a tax credit embodiment, potential tax credit opportunities can be identified from within the depository. The search parameters can be designed to identify particular activities in accordance with relevant tax laws and regulations.
