Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention, when inputting kana-kanji conversion for inputting kana character strings as corresponding kanji kana kanji notation, selects a specific word from a plurality of homophones. This is a homophone learning device for efficient selection.

2. Description of the Related Art In recent years, a kana-kanji conversion device, which has been regarded as a particularly powerful device for easily creating a Japanese document by kana input, has a homophone learning mechanism for quickly selecting a correct word from among homophones. Have been developed.

For example, a so-called homophone usage frequency learning device changes the search order designation information of homophones in the word dictionary based on the usage frequency of the words used in the word dictionary, and quickly obtains the frequently used words. Is possible.

Also, a device called a homophone usage order learning device stores the usage history information of the words in order and stores them in the input kana string each time a specific word is selected from the words having a plurality of homophones in the word dictionary. On the other hand, the homophone selected immediately before is used as the first search word, and the homophon selected before that is sequentially output as the second search word, so that the word used recently can be obtained earlier.

Conventionally, in order to realize the functions of the homophone usage frequency learning and the homophone usage sequence learning together, corresponding mechanisms are provided.

For example, in the homophone usage order learning, the word identifiers that can uniquely limit the words are ordered and stored in the homophone order memory unit, and when the word is searched, the homophone word order memory unit is sequentially searched to search for the homophone words. The order of use learning was realized.

In the homophone usage frequency learning, the usage frequency information in the word dictionary is updated every time a homophone is selected, and the homophone usage frequency learning is performed by searching for the words in the homophony in the order sorted by this usage frequency. Was realized. By having these two mechanisms, both homophone usage sequence learning having the meaning of short-term learning and homophone frequency learning having the meaning of long-term learning can be performed.

(For example, Japanese Unexamined Patent Publication No. 52-132653 and Japanese Unexamined Patent Publication No.
Problems to be Solved by the Invention However, in such a conventional homophone learning device,
The mechanism itself is complicated, and the frequency information of all words must be stored in the word dictionary in association with the words in the word dictionary, making it impossible to use the storage device efficiently. Was there.

The present invention has been made in view of the above problems, and uses a word dictionary compactly with a simple configuration, and enables long-term learning equivalent to homophone usage frequency learning and homophone usage order learning together. The purpose is to provide a learning device.

Means for Solving Problems The present invention provides a word dictionary that stores at least readings and notations of Japanese words to achieve the above-mentioned goal, and a kana input unit for inputting Japanese reading strings by kana. , A homophone selection unit that selects any one of a plurality of homophone variants, a homophone order storage unit that stores the selection order of words selected by the homophone selection unit, and an input from the Kana input unit A character exchanging unit for changing the input kana string into a kanji-kana mixed sentence by searching the homophone order storage unit for the partial string of the Kana string and the word dictionary;
The number of duplicates of words stored in the homophone order storage unit is counted, and with respect to this number, words satisfying a specified condition are first searched in the homophones in the word dictionary.
The homophone learning device includes a dictionary updating unit that rewrites the word dictionary so as to be searched as a homophone.

Operation According to the present invention, the dictionary update unit capable of counting the number of word duplications in the homophone word order storage unit can be easily simulated by using only the word use information stored in the homophone word order storage unit. Frequency learning can be performed. This makes it possible to learn homophone usage frequency with a compact word dictionary,
This makes it possible to perform homophone usage order learning.

Reference numeral 4 denotes a homophone word order storage unit which stores homophone different characters selected by a homophone word selection unit 5 described later in association with their readings and notations in the selected order.

Reference numeral 5 denotes a homophone selection unit which, when there are a plurality of output word expressions from the character conversion unit 3, that is, when there are homophone variants, these are designated as the next candidate instruction code z3 from the homophone designation device 9 described later. The display unit 6 to be described later in order by input
Is displayed on the screen, and the operator can select the desired notation.

A display unit 6 displays the word notation selected by the word selection unit 4 on the screen.

Reference numeral 7 denotes a word dictionary updating unit, which counts the number of times of duplicate occurrence of each homophone variant stored in the homophone order storage unit 4, and when the number exceeds the prescribed value 3, the homophones in the word dictionary 2 are counted. Re-store homophones so that the storage order in the different characters is first.

Reference numeral 8 is a word dictionary update designation device, which is a dictionary update instruction code z5.
By inputting, the word dictionary updating unit 7 is instructed to change the storage order of the homophone groups of the word dictionary 2 based on the current contents of the homophone order storage unit 4.

Reference numeral 9 is a homophone word designating device, which outputs a next candidate designation code z3 and a definite code z4 meaning completion of selection in a homophone variant to the homophone word selection device 5.

The operation of the homophone learning device of the present embodiment configured as described above will be described below with reference to the flowchart of FIG.

〔Character conversion〕

(1) The kana string k input by the operator from the kana input unit 1 is sent to the character conversion unit 3 in a format with the conversion instruction code z1 or the hiragana display instruction code z2 added to the end.

(2) The character conversion unit 3 is the input kana string k from the kana input unit 1.
When the end of is a hiragana display instruction code z2, the hiragana notation of k is output to the homophone selection section 5 as a word notation.
That is, control is transferred to (5).

(3) The character conversion unit 3 sequentially searches the homonym word order storage unit 4 and the word dictionary 2 for the input kana string k, and sends out a word having a corresponding reading to the homonym word selection unit 5 together with the input kana string k in the search order. . At this time, if there are a plurality of homophone variants, they are all output to the homophone selection unit 5.

(4) The homophone selection unit 5 first determines whether or not the word received from the character conversion unit 3 includes homophone variants. If included, control is transferred to the process (6). If not, the following process (5) is performed.

(5) The display unit 6 outputs the notation of the word delivered from the homophone selection unit 5 to the display unit 6 and displays it on the screen, and then enters the input waiting state.

(6) The homophone selection unit 5 outputs the first received word notation in the delivered homonyms to the display unit 6 and displays it on the screen, and at the same time provides guidance for the operator to select the homophone on the display screen. After sending out, it will be in input waiting state.

[Homophone selection]

(7) When the operator inputs the next candidate instruction code z3 from the homonym designation device 9 while the guidance for homonym selection is displayed, the homonym selection unit 5 displays the same homophones in the order received from the character conversion unit 3. Display one word notation in order.

(8) When the operator obtains the desired word notation on the screen, the operator inputs the confirmation code z4 from the homophone designation device 9. Then, the homophone selection unit 5 outputs the selected word notation to the homophone order storage unit 4 together with the input kana string k.

(9) The homophone order storage unit 4 stores the selected homophones and different characters in the selected order internally. At this time, the homophone order storage unit 4 stores the latest word position information indicating which is the latest stored word. After storing the word, it waits for input again.

[Word dictionary update]

(10) In the input waiting state, when the operator inputs the word dictionary update instruction code z5 from the word dictionary update instruction section 8, the word dictionary update section 7 operates.

(11) When the word dictionary update unit 7 is instructed to update the word dictionary by the word dictionary update instruction unit 8, if there are duplicate words by enumerating the stored word contents of the homonym order storage unit 4 at that time, Count the frequency.

After that, only the words having the duplication frequency of 3 or more are identified and stored as the homophone priority output word together with the duplication frequency.

(12) For each of the above-mentioned homophones prioritized output words, a retrieval by reading is performed in the word dictionary 2, and the storage order is changed so that the storage position in the homophone variant group is first in descending order of the degree of duplication.

According to the present embodiment, for the duplicate words in the homophone sequence storage unit 4, the homophone storage order in the word dictionary 2 is updated in order from the one with the smallest degree of duplication, so that the homophones are listed in order from the one with the most duplicates. Words are stored and a more appropriate word dictionary update function is realized.

EFFECTS OF THE INVENTION As is clear from the above description, this homophone learning device is
To realize the above-mentioned functions in a compact configuration without having the frequency information in the word dictionary for the homophone usage order learning and the homophone usage frequency learning, and without preparing a special storage device for the frequency learning. Can be done. According to the present invention, the area for learning the word use frequency, which has been conventionally held for each word in the word dictionary, is unnecessary.
