Abstract: PURPOSE: To surely avoid an error by utilizing a dictionary for postprocessing error correction in online recognition of hand-written character. CONSTITUTION: In a verification block 26, a recognized character string is collated with the dictionary in a block 28 to check whether the dictionary has a word having this spelling or not. If the dictionary has this word, the word is given to a cache integrated block 30, and the output word is given to a line 31. If the dictionary doesn't have the word, character collation marks are calculated in a block 32; and if marks per character reach a determined level, the word is outputted to the block 30, and the output word is given to the line 31, and stroke collation is calculated in a block 34, and a hypothesis of best match is marked and preserved together. The final word hypothesis of best collation marks is inserted to a global word hypothesis list, and thereafter, the output of a collation block 34 is given to a spelling support block 36, and words resembling the character string are searched in the dictionary and are inserted to the global word hypothesis list.
