Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a Japanese input device that performs kana-kanji conversion using word-separate input, phrase-separate input, or solid-letter input.

Conventionally, in Japanese input devices using a kana-kanji conversion method, when the conversion result desired by the operator does not appear as a first candidate, the operator obtains the desired result by selecting a homophone. If we pay attention to the homophone group that is the target of this homophone selection, we will find out whether or not the kana notation is included in the homophone group.
Or even if it is included, it is ranked as the lowest priority in the homophone group. However, for example, regarding the word "Thank you", there are cases where the kana name "Thank you" is used depending on the person and the type of document used.

However, as mentioned above, with conventional devices, when converting kana to kanji using word-separated input, phrase-separated input, or solid input,
It is necessary to forcefully specify a character type in part, or it takes time to select the kana notation at the lowest level of the homophone group.

In view of the above drawbacks, the present invention provides word separation input,
To provide a Japanese input device that allows an operator to quickly obtain desired kana notation when converting kana to kanji by segmented bunsetsu input or solid input.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a Japanese language input device according to an embodiment of the present invention. In the figure, reference numeral 1 denotes a key reading unit, which reads the pressed key and, depending on the type of the pressed key, a kana word string conversion unit 5, an output notation string creation unit 7, or kana notation selection history information, which will be described later. Either the update section 9 is activated, or the kana string is stored in the input buffer 2, which will be described later. 2 is an input buffer that stores the input kana string. 3 is a word dictionary that stores at least the reading of words, kanji notation, and kana notation selection history information. Reference numeral 4 denotes a buffer for word string information, which stores word string information output from a kana word string converter 5, which will be described later, or homophone output priority information, which is an output from a homophone output priority determiner 6, which will be described later. Reference numeral 5 denotes a kana word string conversion unit which converts the kana in the input buffer 2 into a word string while referring to the contents of the word dictionary 3, and stores the result in the word string information buffer 4. Reference numeral 6 denotes a homophone output priority determining unit, which determines the output priority of homophone groups and kana notation by referring to the word string information and the kana notation selection history information of the word dictionary 3, and uses the results for word string information. Store in buffer 4. Reference numeral 7 denotes an output notation string creation section, which refers to the word string information output from the kana word string conversion section 5, the homophone output priority information output from the homophone output priority determination section 6, and the word dictionary 3. Create an output representation column. (However, at this time, for the words in the word dictionary 3, only the kanji notation in the dictionary is read out, but for the kana notation, this includes creating the kana notation based on the pronunciation in the word dictionary 3.)8 is an output section that displays or prints the notation string that is the output of the output notation string creation section 7. Reference numeral 9 denotes a kana notation selection history information update unit, in which a key is pressed to confirm the notation in the key reading unit 1, and the kana notation of the word in the word dictionary 3 is included in the notation string being output at that point. In this case, the kana notation selection history information of the word in the word dictionary 3 is updated.

The operation of the above configuration will be explained below.

First, the key reading section 1 reads the pressed key, and if it corresponds to a kana, stores it in the input buffer 2 sequentially, and if it starts conversion, starts the kana word string conversion section 5. In addition, if the next notation in the homophone group is requested, the output notation string creation unit 7 is started, and if it means confirmation of the notation, the kana notation selection history information update unit 9 is activated. Activate.

Now, if the key pressed in the key reading section 1 is the one that starts the conversion, the kana word string conversion section 5 reads the kana string from the input buffer 2 and converts it into a word string while referring to the contents of the word dictionary 3. The resulting word string information is converted into word string information buffer 4.
Then, the homophone output priority determining unit 6 is activated. For example, suppose that the input kana string "Arigatai" is converted into the word string "Thank you". Assuming that such a word string consists of one word and that there is no other notation for it, the contents of the word string information buffer 4 will be as shown in Figure 2a,
In this case, the word dictionary 3 is associated with a point (or address) A in the word dictionary.
Also, Figure 2b is an example of word information in the word dictionary,
X is a term indicating reading, Y is a term indicating kanji notation, and Z is a term indicating kana notation selection history information. Note that kana notation selection history information Z is information indicating whether or not kana notation was selected at the most recent selection occasion for the homophone group, and if it was kana notation, "1" ” is also written in kanji, it is assigned “0”, and therefore, in Figure 2 b
Regarding the word "thank you" shown in , "1" indicating that the kana notation was selected in the previous homophone selection opportunity is stored in the Z term.

On the other hand, the homophone output priority determination unit 6 is activated by the kana word string conversion unit 5 and refers to the word string information shown in FIG. 2a and the corresponding kana notation selection history information in the word dictionary 3. Then, output notation priority information as shown in FIG. 2c is created. In other words, in the case of the current example, the word string information in Figure 2a indicates that the word "thank you" has no homophones, so the number of notations is "thank you".
The kanji notation is ``thankless,'' and the kana notation for this word is ``thankless.'' In addition, the output priority order among them is that, as shown in the Z term in Figure 2b, kana notation was selected at the previous homophone selection opportunity, so this is reflected in the output. In this case, the first priority notation is set as kana notation, and the point in the word dictionary of the first priority notation is a specific value, which is assumed to be 0 here, to indicate that it is kana notation, and the second
The priority notation in the word dictionary is point "A" for the word "thank you".

Thereafter, the homophone output priority determination unit 6 sets 0 as the initial value of the priority of the currently displayed notation, as shown in FIG. 2d, and outputs the output notation string creation unit 7.
Start. Then, the output notation string creation section 7 activated by the homophone priority determination section 6 or the key reading section 1 creates an output notation string based on the contents of FIG. 2 b, c, and d. That is, the priority term of the currently displayed notation is incremented by 1, and if the result becomes a value greater than the number of notations, the value is set to 1. Then, the notation of the corresponding priority order is extracted from the word dictionary 3 based on the points in the word dictionary. If the point in the word dictionary is a specific value indicating that it is in kana notation, that is, "0", the reading of the word is extracted based on the points in the word dictionary of the preceding and following priority notation, and based on this reading. , for example, by code conversion to create a kana notation.

Note that when the output notation string creation section 7 is activated by the homophone priority determination section 6, it performs nothing but an operation for outputting the first candidate as a result of the kana word string conversion; On the other hand, when activated by the key reading section 1, it is nothing but an operation for outputting the next candidate of the candidate output at that time. Therefore, in the former case,
Corresponding to the example explained using Fig. 2, and adding a little explanation, in this case, as shown in Fig. 2 d, the priority term of the currently displayed notation is "0".
Therefore, it is incremented by 1 and set to "1". After that, if you take out the point in the word dictionary for the first candidate notation, it will be "0" as shown in Figure 2c.
becomes. In other words, since "0" is a value indicating kana notation, read from the word dictionary 3 based on point A in the word dictionary of the notation in the priority order after it,
Take out “Arigatai” and convert this reading to the kana notation “Thank you”, for example, through a code conversion process.
can be obtained.

After the above operations, the output notation string creation section 7 activates the output section 8 and transfers the output notation string to the output section 8. Then, the output unit 8 activated by the output notation string creation unit 7 presents the conversion result to the operator by displaying or printing the output notation string.

On the other hand, the kana notation selection history information update unit 9 is activated by the key reading unit 1 when the notation is confirmed, and if the notation being output at that time is a kana notation, the kana notation selection history information update unit 9 is activated in the Z term in the dictionary 3 of the corresponding word. , the value “1” indicating that kana notation was selected at the previous homophone selection opportunity.
Store. If the notation being output is kanji notation, a value "0" indicating that kana notation has not been selected is stored. Then, the determination as to whether or not the notation being output at that point is kana notation is made based on the priority order shown in FIG. 2 d at that point.
This can be done by extracting a point in the word dictionary 3 and determining whether the value is a specific value indicating that it is written in kana.

As described above, according to this embodiment, the output priority order of kana notation in a homophone group is determined based on the kana notation selection history information, and the output priority order of kana notation in a homophone group is determined based on the kana notation selection history information, and By updating the kana notation selection history information of a word, the kana notation can be selected as having the first output priority among the homophones. In other words, the conversion results for the input kana string “mata” are “mata”, “mata” and the kana notation “mata”
If you select the kana notation “Mata” from the menu, if you enter the kana string “Mata” again and convert it, the first
The kana notation "mata" can be obtained as a priority. Therefore, when the kana notation "Mata" is desired, it is not necessary to request the next candidate in order of "Mata", "Mata", and "Mata" each time.

As described above, according to the present invention, there is a means for storing word pronunciation, kanji notation, and kana notation selection history information, a means for converting a kana string into a word string, and a means for storing the word string. means for determining the output priority order of kana notation in the homophone group based on the kana notation selection history information; means for creating the kana notation of the word from the pronunciation of the word; By providing means for updating the kana notation selection history information in at least one word data, it is possible to select the kana notation as having the first output priority among the homophone groups. , when using any of the Kana-Kanji conversion methods such as word splitting, bunsetsu splitting, and solid writing input,
When an operator wants to repeatedly obtain the kana notation for the same reading, the desired result can be obtained without the need for special character type specification operations and with fewer opportunities for homophone selection operations. , its practical effects are great.
