Description

Description: TECHNICAL FIELD The present invention relates to a document processing device, and more particularly to a device capable of efficiently outputting Chinese characters used in combination with numbers.

[Prior Art] Conventionally, in a device of this kind that converts a Japanese sentence input in kana or romaji into a kanji-kana mixed sentence, when converting to a character string composed of numbers and kanji connected before and after the number, There is a problem that homonyms are often output. In order to solve this problem, for example, (1) JP-A-55-44610 and (2) JP-A-55-92921 have been proposed.

(1) In Japanese Patent Laid-Open No. 55-44610, if input kana characters before and after numbers are inserted, and these are used as prepositional numeral (prefix before number) and postpositional numeral (numerical suffix after number) Focusing on the correspondence between these classifiers, all combinations of prepositional and postpositional classifiers having a correspondence relationship are registered as a table, and conversion is performed by referring to this table. It was to facilitate the conversion of homonyms, which was difficult with.

(2) In Japanese Patent Application Laid-Open No. 55-92921, numbers are input from the number keys of a kana keyboard, and kanji as a classifier used in connection with the numbers are stored in separate tables. It was to facilitate the conversion of difficult homonyms.

[Problems to be Solved by the Invention] However, the above-mentioned proposal has the following problems.

(1) In Japanese Patent Laid-Open No. 55-44610, in order to convert a prepositional auxiliary numeral and a postpositional auxiliary numeral having a predetermined correspondence, a corresponding auxiliary numeral table in which all the combinations are registered is used. This correspondence classifier table is arranged in order from the one with the largest number of kana character strings. For example, "dai one"
When the input string is input, the kana character string before the number is compared with the left half of the corresponding classifier table, that is, the prefix classifier table, and the kana character string after the number is compared with the right half, that is, the postpositional classifier table. , If there is a match, it is converted to the corresponding kanji and output. In other words, since all combinations must be checked from the beginning of the corresponding classifier table, a lot of processing time is spent in the Kana-Kanji conversion processing.

(2) In Japanese Patent Laid-Open No. 55-92921, words that are often used before, after, or before and after a number are stored in separate tables. Since each of these tables is searched independently, it is quite possible that the output ignoring the correspondence between the prepositional auxiliary numeral and the postpositional auxiliary numeral will be the same as the output of the correct conversion result.

Therefore, an object of the present invention is to facilitate the conversion of a kana-kanji conversion that converts a character string composed of numbers and the kanji connected before and after the number, even if there are homonyms, and to perform the conversion process. An object is to provide a document processing device that requires a short time.

[Means for Solving the Problems] Therefore, in the present invention, it is composed of a number and a prepositional auxiliary number as a prefix connected before the number and a postpositional number as a particle connected after the number. In a document processing device for converting a syllabary clause into a kana-kanji syllabary, a number dictionary for storing a numeral and a character corresponding to the number, and a postpositional number dictionary for storing a postfix and a letter and a number corresponding to the postfix. , Prepositional auxiliary words and the characters corresponding to the frontal auxiliary words, and the prepositional auxiliary word dictionary that stores the connection relationship between the postpositional auxiliary words and the postpositional auxiliary words corresponding to the numbers according to the state of the flag, and the number clause are input. And a conversion control means for retrieving a number dictionary, a prepositional auxiliary number dictionary, and a postpositional auxiliary number dictionary, and converting and outputting to a predetermined kana-kanji clause based on the connection relationship. And

[Operation] According to the above-described configuration, the prefix auxiliary numeral is connected before and after the numeral by providing the flag with the information of the postpositional auxiliary numeral that may be connected corresponding to the prefix auxiliary numeral. It becomes possible to convert to Kanji.

Fig. 4 is a schematic diagram showing a numeral dictionary to be referred to when converting arithmetic numbers input by the number keys of or numeric characters input by phonetic kana, Fig. 4 is stored in the PSTDIC of RAM3 and the kana connected after the number is FIG. 3 is a schematic diagram showing a postpositional numeral dictionary that is referred to when converting to kanji. Yomi (YF) and character code (KF) are recorded in the dictionary, and consecutive letters are added to each of the postpositional numeral. These correspond to the heading numbers (bit numbers) in the connection table with the postpositional classifier in the prepositional classifier dictionary. FIG. 5 is a connection table of the input auxiliary kana and the postpositional auxiliary words that match the input auxiliary kana, and is a schematic diagram showing a portion copied to the working memory CONDW in the RAM3.

In the connection table of each of the above figures, "1" indicates that there is a correspondence relation between classifiers, and "0" indicates that there is no relation.

Next, referring to the flowchart of FIG. 7, the conversion process between the prepositional auxiliary numeral and the postpositional auxiliary numeral according to the present invention will be described by taking the case of inputting the character string “first time” as an example.

When a kana character string "Daichi 1 kai" made up of a prepositional numeral, a numeral and a postpositional numeral is input, first, step S12.
In PERDIC's Prepositional Numeral Dictionary (Fig. 2)
Is searched. Next, in step S13, it is determined whether or not a candidate corresponding to "dai" has been found. If there is a “first” candidate for “dai”, step S1
4 and step S15, and in step S14, step S
The reading (YF), character code (KF), and connection table (partial CONDIC in Fig. 5) corresponding to the prepositional classifier found in 13 are copied to CONDW in RAM3.

On the other hand, in step S15, the NUMDIC number dictionary is searched for the number "1", and it is determined whether or not it is found in step S16. If found, proceed to step S17, P
Search for "kai" in the STDIC postpositional dictionary (Fig. 4). Then, it is determined whether or not it is found in step S18. If the candidate "times" is found, the process proceeds to step S19, the connection table with the postpositional classifier copied to CONDW in RAM3 is referred to, and the prepositional classifier and postpositional code found based on the serial number of the postpositional classifier are detected. The connection check is made to see if the classifiers have a correspondence and the correct one is determined. In this connection check, if the connection flag is "1", the connection is determined to be correct, and if the connection flag is "0", the connection is determined to be incorrect. That is, since "times" have a serial number of 1, the flag of the 1st bit of the connection table with the postpositional classifier copied to CONDW is checked, and if the connection flag is "1", the connection Is determined to be correct, and if the connection flag is "0", the connection is determined to be incorrect.

If it is determined that the connection is correct, proceed to step S21,
The combination of the prepositional numeral, the numeral and the postpositional numeral is sent to the document buffer TBUF. According to the connection check table in Fig.5, the one with "1" in the first bit is
Since it is "No.", it is "No."
Is determined to be the correct connection and is selected, and the “first time” output can be obtained.

If it is determined that the connection is not correct, the process proceeds to step S22, the prefix particle dictionary is searched again after the prefix particle found in the first search, and it is determined whether or not it is found in step S23. In the case, the process proceeds to step S19 again.

Post-positional number dictionary search in steps S12 and S13, number dictionary search in steps S15 and S16, step S1
7. If no match is found in the prepositional numeral search in steps S18, S22, and S23 in each dictionary, no kana reading buffer (YBUF) to document buffer (TBUF) is found in step S24. It is sent out as converted.

In the first embodiment, the connection relationship (correspondence relationship) between the prepositional auxiliary word and the postpositional auxiliary word is divided into two states, that is, whether to connect or not, but instead of the prepositional auxiliary word dictionary as shown in FIG. If a prepositional numeral dictionary having a connection relation with a frequency as shown in FIG. 8 is used, those having a reliable connection relation to those having a possibility of connection are output in descending order of frequency. For example, for an input such as "Daily 1",
In the first embodiment, only the "first time" was output, but according to the second embodiment, the "first time" is output to the first candidate,
Then, "first floor" is output as the second candidate.

FIG. 9 is a flow chart showing the process of conversion of the prefix and the postfix in the second embodiment of the present invention. The difference from the flowchart of the first embodiment is the process of step S21 '. In step S21 ', a plurality of combinations for which the connection is determined to be correct are rearranged based on the frequency of the connection table in the prepositional dictionary, and the document buffer TBUF
It is a process of sending out to.

[Effects of the Invention] As is clear from the above description, by providing a prefix with the information of the postpositional auxiliary that may be connected corresponding to the prepositional auxiliary, the flag is used as a medium. It is possible to convert to kanji that connects before and after. This allows
It becomes possible to easily and accurately perform conversion in which homonyms exist, and it is possible to shorten the processing time for such conversion.

Therefore, it was possible to improve the operability associated with kana-kanji conversion.
