Abstract

PURPOSE:To simplify operations and to shorten the processing time by automatically selecting a rejected character according to a word dictionary in terms of recognizing sentence information. CONSTITUTION:Word data is inputted through an input part 11 to read characters or as accumulated data, and a recognition part 12 recognizes the characters. A word buffer 13 temporarily stores the result obtained by recognizing input character data and character data selected by a rejected word selection part 16. A next candidate buffer 14 temporarily stores a next candidate if it is present by rejecting the recognized result. The word dictionary 15 stores a character string composed of words in Japanese alphabetical order of a top character. If no rejected character is found through the recognized result, the characters are outputted as they are from an output part 17. If the rejected character is present, the selection part 16 selects the rejected character in combination with a piece of next candidate information in the word dictionary 15 and in the next candidate buffer 14 according to presence or absence of the next candidate. The word dictionary 15 selects the rejected character and outputs it from the output part 17.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a character selection method that automatically selects a rejected character when an input character is rejected in character recognition, voice recognition, or the like.

(Prior art) In character recognition, voice recognition, etc., a word consisting of four letters, such as "hanjitsu", is input, and the third word is recognized as the recognition result.
As shown in the figure, when the last fourth character is rejected, conventionally the user manually inputs the fourth character "tsu" using a keyboard or the like. Therefore, there is a problem that the operation becomes complicated and the processing takes time.

(Objective of the Invention) The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a character selection method that automatically selects and inputs reject characters.

<Example> FIG. 1 shows the functional configuration of the true and unbelievable character selection method.

The input unit 11 includes a tablet, a character reader, or the like for inputting text information. The recognition unit 12 recognizes input character data character by character using a known method. The word buffer 13 temporarily stores recognition results of input character data and character data selected by the reject word selection section 16. The next candidate buffer 14 temporarily stores the next candidate when there is a next candidate in the recognition result paste or the like. The word dictionary 15 stores word strings in alphabetical order of the first letter, for example. The reject word selection section 16 selects the reject character by referring to the contents of the word dictionary 15 and the next candidate buffer 14 when one or more characters are duplicated during the recognition process of the input word data. Output section 1
7 consists of a display device, a printer, etc., and outputs the character data stored in the word buffer 13. Control unit 18
consists of, for example, a CPU, and controls each of the above elements according to a control program.

FIG. 2 shows the processing procedure of this character selection method.

When word data is input as character reading or stored data (step 532), recognition processing is performed (step 533), and if there are no reject characters, the recognition result is output as is (step 838). If there is a reject character, a reject character is selected based on the combination of the word dictionary 15 and the next candidate information depending on whether there is a next candidate (step 836
) or select a reject character using the word dictionary 15 (step 537). Then, the result is output (step 538).

For example, if the aforementioned character string "hanjitsu" is input and the recognition result is that the fourth and final character "tsu" is a rejected character, the procedure for deriving this reject character "tsu" is as follows.

i) Since the input word is a four-letter word, the search in the word dictionary 15 is limited to four-letter words.

1i) The first to third characters of "hanshi" are recognized.

iii) Referring to the contents shown in FIG. 4 of the word dictionary 15,
°Select and output the correct character string "hanjitsu". In this case, if other character strings such as "Hanjiko" appear,
Select candidate strings in ascending order of distance. Furthermore, even if there are no candidates at all, the correct character string is selected.

<Effects of the Invention> As explained above, in the present invention, reject characters are automatically selected based on a word dictionary when recognizing text information, which simplifies operation and reduces processing time. can.
