Abstract
The system described herein automatically defines a set of radicals to be used in a Kanji character handwriting recognition system and automatically creates a dictionary of the Kanji characters that are recognized by the system. In performing its functionality, the system described herein first obtains representative handwriting samples for each Kanji character that is to be recognized by the system. The system described herein then evaluates the samples to identify a set of subparts (“radicals”) that are common to at least two of the Kanji characters. These radicals represent component roots from which the characters are formed. Each Kanji character is formed by one or more of these radicals. The radicals that are identified by the system described herein are not constrained to any preset definition (e.g., the traditional set of radicals used to organize Japanese dictionaries). Thus, the radicals utilized by the system described herein may include some of the traditional radicals or may include none of the traditional radicals. After identifying the set of radicals, the system described herein generates a dictionary with a mapping of each Kanji character that is to be …
