The authors shown many advantages of using postal syntacticfeatures in address block location. Performing character recognition atlow resolution (100 PPI) is desirable for a real-time system. Anefficient word matching algorithm is designed to match words against adictionary of about 500 keywords and assign a syntactic tag to each wordin a text block. The critical information and the street syntax areextracted by parsing the syntactic tags. The usage of the postalsyntactic features has been introduced in many aspects such asrecovering lost information, selecting a more likely destination addressblock, and improving destination address block segmentation. Withcharacter recognition available in the system, the utilization of othersyntax and context information on the mail pieces becomes feasible. Theinitial testing results of the incorporation of the syntactic processingin address block location were positive and encouraging
