The user-defined inference rule is created using a knowledge base search language that is basically provided in a knowledge base management system. Accordingly, the user-defined inference rule is a knowledge base search statement and is processed using a function of searching a knowledge base as a base function of the knowledge base management system. The user-defined inference rule is applied by including a knowledge base search process and a search result in the knowledge base, when the knowledge base is changed. The user-defined inference rule is managed by a user-defined inference rule manager. The user-defined inference rule manager monitors a change in the knowledge base to determine when the user-defined inference rule is applied, executes the user-defined inference rule to obtain the execution result, and includes the execution result in the knowledge base.

摘要:
An apparatus and method for correcting a scanning error in a flatbed scanner, can minimize the scanning error due to deviations in position or scanning of a CCD (charge-coupled device) module by determining a scanning position, a scan region, and a scan rate for each flatbed scanner. The scanning error correcting apparatus includes a white shading plate having a black patch, a reading module for reading the white shading plate and the black patch, and a controller that compares information about the black patch read by the reading module with a predetermined reference value to correct the scanning error in the flatbed scanner. Thus, the apparatus and method can secure a scanning region in horizontal and vertical directions as wide as possible for each flatbed scanner and prevent occurrences of errors in a scanned image due to deviations of the CCD module. Furthermore, the apparatus and method provide an accurately scanned image having a desired scan rate by comparing right and left sizes and the entire scan size for a currently scanned region.
