It is also possible to add the "unknown word estimation start" key to the input means so that the user can estimate the unknown word by himself / herself.

[0016]

Embodiments of the present invention will now be described in detail with reference to the drawings.

The block diagram of FIG. 1 shows the construction of a character processing apparatus according to an embodiment of the present invention. In FIG. 1, reference numeral 101 denotes a kana-kanji conversion engine, which performs “kana-kanji conversion processing” and “deletes the converted character string” when the converted character string is lost.
Message when the conversion confirmation key is pressed, and a message “conversion confirmation” is sent to the message receiving unit 102. For example, in the example of FIG. 5, the kana-kanji conversion engine 101 sends a "conversion character string deletion" message after inputting the "BS" key (backward key) in step t13, and a conversion confirmation after inputting the "confirm" key at t22 and t32. "send a message. The message receiving unit 102 receives these messages from the Kana-Kanji conversion engine 101, and determines whether the message is “delete conversion character string” or “confirm conversion”.

Reference numeral 103 is a reception notification (affirmative judgment) of the "conversion character string deletion" message from the message receiving unit 102.
Is an unknown word estimation processing unit that estimates an unknown word that is not registered in the Kana-Kanji dictionary 106 according to. An unknown word registration processing unit 104 registers an unknown word in the Kana-Kanji dictionary 106 in response to a notification (affirmative determination) of receiving a "confirmation of conversion" message from the message receiving unit 102. A keyboard 105 is an example of an input unit. The kana-kanji conversion engine 101 performs kana-kanji conversion processing by using the kana-kanji conversion engine 101.

Reference numeral 107 denotes an input key buffer (buffer memory) for storing an input key string from the keyboard 105. An unknown word reading key buffer 108 stores a key string having unknown word reading information. An unknown word notation key buffer 109 stores a key string having unknown word notation information.

The flowchart of FIG. 2 shows the procedure of the overall processing operation of the embodiment of the present invention in the configuration of FIG. In addition, S in S201 and the like in the figure represents a step. Further, in the input example of FIG. 5 described later, the input mode from the keyboard 105 is set to romaji, but kana (hiragana key)
However, it goes without saying that the same processing is performed.

First, in step S201, the message receiving unit 102 determines whether the message sent from the kana-kanji conversion engine 101 is the above "conversion character string deletion".
Determined by If this determination is affirmative (yes), the process proceeds to the unknown word reasoning process of S202 by the unknown word estimation processing unit 103, and if negative (no), the process proceeds to the determination process of S203.

In step S203, the kana-kanji conversion engine 101
The message receiving unit 102 determines whether or not the message sent from is the above-mentioned “confirmation of conversion”. If this determination is affirmative (yes), the unknown word registration processing unit 104 proceeds to the unknown word registration processing of S204, and if negative (no), the processing returns to the determination processing of S201. After the processes of S202 and S204 are completed, the process returns to the determination process of S201.

The flowchart of FIG. 3 shows an operation procedure (process) of the unknown word estimation processing of S202 of FIG. 2 by the unknown word estimation processing unit 103. First, in S301, it is determined whether or not the unknown word reading key buffer 108 in FIG. 1 is empty. If this determination is a positive determination, the process proceeds to S303, and if the determination is negative, the process proceeds to S302.

In S302, the unknown word reading key buffer 1
Clear 08 to empty. Then, the process proceeds to S304.

On the other hand, in S303, the input key buffer 1
In 07, a character string excluding "conversion" and "BS" which are control commands of the kana-kanji conversion engine 101 (in the example of FIG. 5, "jansou" at t14, for example) is copied to the unknown word reading key buffer 108. (Copy) Then S30
The process shifts to the process of No. 4.

In step S304, the input key buffer 107 is cleared to be empty. In the example of FIG. 5, it corresponds to t14.
Then, the process is terminated and the process returns to the main routine of FIG.

The flowchart of FIG. 4 shows an operation procedure (process) of the unknown word registration processing of S204 of FIG. 2 by the unknown word registration processing unit 104. First, in S401, it is determined whether or not the unknown word reading key buffer 108 in FIG. 1 is empty. If this determination is affirmative, the process jumps to S406, and if negative, the process proceeds to S402.

In S402, the unknown word reading key buffer 1
It is determined whether a part of the character string in 08 is included in the character string of the input key buffer 107. If this determination is affirmative, the process proceeds to S403, and if negative, S
Jump to 406 processing. In the example of FIG. 5, the character string “so in the unknown word reading key buffer 108 is reached at t32, for example.
Since "u" is included in the character string of the input key buffer 107, the determination in S402 is affirmative.

In step S403, the contents of the input key buffer 107 are added to the unknown word writing buffer 109. Next S40
At 4, it is determined whether or not all the character strings in the unknown word reading key buffer 108 are included in the character strings in the unknown word writing key buffer 109. If this determination is affirmative, S
If the determination is negative, the process ends, and the process returns to the main routine of FIG.

In step S405, the kana-kanji dictionary 10 shown in FIG.
Register unknown words in 6. Here, the kana character string in the unknown word reading key buffer 108 is used as the unknown word reading, and the output when the character string in the unknown word notation key buffer 109 is passed to the kana-kanji conversion engine 101 is referred to as the unknown word expression. To do. In the example of FIG. 5, for example, at t33, the reading of the unknown word is “Janso”, and the notation of the unknown word is “Jakuso”. The character string "majan
When [Convert] [Confirm] [←] [←] [Delete] [→] sou [Convert] [Confirm] ”is input, t15 to t3 in FIG.
Following the state up to 2, "Jakuso" is the above output. At this time, the screen at t32 also becomes "Sparrow Villa". Next, S406
Move on to processing.

In step S406, all buffers, the input key buffer 107, the unknown word reading key buffer 108, and the unknown word writing key buffer 109 are cleared to empty. In the example of FIG. 5, it corresponds to t34, for example.

(Other Embodiments) In the above-described embodiment of the present invention, unknown words are automatically registered in the Kana-Kanji dictionary 106 without confirmation by the user, but the present invention is not limited to this. When registering an unknown word in the Kana-Kanji dictionary 106, it may be configured to confirm once with the user and register the unknown word that the user has approved for registration in the Kana-Kanji dictionary 106.

In addition, in the above-described embodiment of the present invention, when registering an unknown word in the Kana-Kanji dictionary 106, the priority of the word is not particularly considered, but the present invention is not limited to this. When registering an unknown word in the Kana-Kanji dictionary 106, the unknown word to be registered has a lower priority than other words (registered words), and is the same as the word registered by the unknown word registration processing unit 104. If the written word has already been registered, it is possible to make the newly registered word less likely to be selected than the existing word.

Further, in the above-described embodiment of the present invention, the kana-kanji conversion engine 101 sends the message "conversion character string deletion" to cause the unknown word estimation processing unit 103 to perform the unknown word estimation processing. The present invention is not limited to this, and the keyboard 10 is used instead of the message transmission and estimation processing.
It is also possible to add a "start unknown word estimation" key to 5 and configure the user to estimate the unknown word by himself.

The present invention may be applied to a system composed of a plurality of devices (eg computer system) or an apparatus composed of one device (eg word processor or word processor). Further, it goes without saying that the present invention can be applied to the case where it is achieved by supplying a program to a system or an apparatus.

[0036]

As described above, according to the present invention, when an unknown word not registered in the Kana-Kanji dictionary appears, the device can automatically register the unknown word in the Kana-Kanji dictionary. From the next kana-kanji conversion, the word will no longer be an unknown word, and the effect of eliminating the need for troublesome input operations will be obtained.
