Abstract: The present invention provides a system and related method that enables a user to use one or more appropriate ROI tools according to the needs of the users. Specifically, the user provides data related to the organizations and technical expenditures, and this information is used to determine an applicable set of ROI tools. The inputted data is then provided to the applicable ROI tools for automatically examining a company's financial data, and using this evaluation to assess the desirability of technology expenditures.

Abstract: A system including a document repository is provided. The system determines, automatically, a level of similarity between at least two of a plurality of discrete elements stored in the document repository. The system then stores data representative of a link between the elements based in-part on the level of similarity. In another embodiment, the system determines a relationship between documents by retrieving a plurality of documents from a document repository. The system segments at least two documents of the plurality of documents into a plurality of conceptually meaningful segments. The system determines if a segment of one document is related to a segment of another document and stores data representative of the relationship.

Abstract: In a data transmission system, for communicating messages between a base station and a plurality of mobile stations, each mobile station includes a radio frequency transceiver and a programmable data terminal for sending and receiving predeterminedly formatted digitally encoded messages. A keyboard subsystem and character display subsystem are controlled by a programmable microprocessor subsystem which also processes received and transmitted messages. A transmit and receive system clock interrupts the operation of the microcomputer to process messages. The messages include a cyclical redundant check byte as well as a control number byte. Characters which are not editable blink. A terminal status display line is provided and a message received character is also provided. The system sets the system clock period to be the same for all data rates. Automatic restart of the system is provided as well as a means for detecting and generating a pseudo-random message preamble.
