Abstract: Traditional information extraction processes are usually implemented on a programmed general purpose computer. The process looks for certain information, and organizes the information into a database record. The database created is usually stored in a searchable format such as a structured relational database or an object-orientated structured database, which can be accessed, research, and analyzed by computer-implemented database research systems. However, generic information extraction processes only input the extracted information into the database, in the last step of the process and do not address the problem of compiling large and comprehensive database from a plurality of source documents. Furthermore, information extraction processes are not focused on how the information extracted will be used in the construction of a large database.

Abstract: A system for processing images includes an image file subsystem providing a source signal representing an input image; a color transformation subsystem coupled to the image file subsystem and accepting as input the source signal and producing a target signal therefrom, and an image forming subsystem coupled to the color transformation subsystem and forming a physical manifestation of the input image in response to the target signal, the color transformation subsystem being configured to establish a memory "cube" area representative of possible source signals, to define a sub-cube portion of the memory area as representative of the source signal; to determine possible target signals corresponding to the sub-cube portion; and to determine the target signal responsive to the possible target signals. If interpolation is found to be accurate for a mini-cube portion of the sub-cube, truncation or interpolation are used to derive the target signal; otherwise, the target signal is determined directly.
