Abstract

PURPOSE:To display the output character strings in the optimum order and regardless of the grammatical type by storing the used words after deciding one of two grammatical types where said words are used. CONSTITUTION:The KANA (Japanese syllabary) strings supplied through an input device 1 are stored in an input KANA string storing part 2. Then a KANA/KANJI (Chinese character) converting part 3 reads the KANA strings and retrieves the words having coincidence of reading out of a word storing part 4. Then the grammatically correct KANA strings are stored in an output character string storing part 7. The output character strings are rearranged in the order of higher priority by means of the word information stored in a word using information storing part 6 and displayed on a display device 8. Here the part 6 stores the word information containing the reading of independent words, the KANJI description and the additional word information is stored for the words used in the past. Then the output character strings are displayed in the optimum order regardless of the difference between two grammatical types 'independent word + additional word' and 'independent word'.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a kana-kanji conversion device for converting a Japanese sentence input in kana to a sentence containing kana and kanji.

BACKGROUND OF THE INVENTION In recent years, kana-kanji conversion devices are the most common means of inputting Japanese, and have been widely used in various Japanese language processing devices including Japanese word processors and saucers.

By the way, there are many homophones in Japanese words, so it may be difficult to uniquely convert a Japanese sentence input in kana to a sentence containing kana-kanji using a kana-kanji conversion device. It is well known that there are many.

Therefore, in order to reduce the number of homophone selection operations performed by the user, by having a means for storing usage information of homonyms selected by the user in the past, homonyms are displayed in order of frequency of use. Methods have been devised to display homonyms in order of most recently used.

Problems to be Solved by the Invention However, since the method described above is based on converting kana-kanji on a word-by-word basis, the following problems arise when attempting to convert kana-kanji on a phrase-by-bunsetsu basis. It had In other words, with conventional kana-kanji conversion devices that can convert kana strings into kana-kanji mixed sentences on a word-by-word or bunsetsu-by-bunsetsu basis, the kana-kanji mixed sentences obtained by performing kana-kanji conversion on the same input kana string are grammatically In terms of perspective, there may be two types of conversion results: one consisting of only an independent word and one consisting of an independent word and an attached word.

For example, for the input kana string ``Kareha'', two types of conversion results are obtained: - dry leaf - independent word ( dry leaf ) `` He is '' independent word ( him ) + adjunct word ( wa ) .

At this time, in the conventional method, if the user selects ``Autumn Leaves'', then ``Autumn Leaves'' is selected among the homophones of the reading ``Kareha''.
On the other hand, if ``he'' is selected, the word ``he'' will have a high priority among the homophones of the pronunciation ``curry.'' In other words, in the conventional method, the above If two types of conversion results are possible, it is possible to determine the priority of homophones among the conversion results belonging to the same type, but which of the two types should be displayed with priority? Therefore, even if the user always selects the conversion result "Kareha" for the input kana string "~Kareha",
There was a problem in that the next time I tried to convert the input kana string ``Kareha'' again, the conversion result ``he was'' would not necessarily be displayed preferentially.

The present invention has been made to solve the above problems.

Means for Solving the Problems The present invention provides "independent words" and "independent words +
When two types of conversion results are obtained with "ancillary word",
In addition to determining the priority of homophones only among the conversion results belonging to the same type, it also takes into account the priority between independent words that belong to two types and have different pronunciation lengths. It is something.

Operation: With the above configuration, a plurality of obtained conversion results can be displayed in an order that is optimal for the user, starting from the one with the highest priority.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of a kana-kanji conversion device according to an embodiment of the present invention. In Figure 1, 1 is a means for inputting a Japanese kana string, and a desired output from among a plurality of output character strings mixed with kana and kanji obtained by performing kana-kanji conversion on the input kana string. The input device includes means for selecting a character string. Reference numeral 2 denotes an input kana string storage unit that stores the kana string inputted from the input device 1. Reference numeral 3 denotes a kana-kanji conversion control section which reads a kana string from the input kana string storage section 2 and generates a character string containing kana and kanji. Reference numeral 4 denotes a word storage unit that stores the pronunciations, kanji notation, and part-of-speech information of words that can be independent words other than particles and auxiliary verbs in association with each other. Reference numeral 5 denotes a grammatical information storage unit that stores information on pairs of adjuncts consisting of particles and auxiliary verbs and information on connections between words.

6 is attached word additional information indicating the pronunciation of a word used by the user among the words stored in the word storage unit and whether or not an attached word was added to the word at the time of use in kanji notation. This is a word usage information storage unit that stores. Note that the storage of word information in the word usage information storage unit 6 involves moving the already stored word information backward by one word and storing the word information used at the latest time in the empty area at the top that is created as a result. so that recently used words are stored near the beginning. 7 prioritizes the pair of the input kana string generated from the kana-kanji conversion control unit 3 with a delimiter inserted at the boundary between independent words and attached words and the output string containing kana-kanji obtained by kana-kanji conversion. This is an output character string storage unit that stores the strings in order from highest to lowest. Note that the output character string storage section is provided with an area for storing priority information for each output character string. 8 is a display device that displays the output character strings stored in the output character string storage unit in order of priority. 9 stores word information of the selected word in the word usage information storage unit 6 when one set of output character strings is selected from the set of output character strings displayed on the display device 8 via the input device 1. This is a word usage information update unit to store.

The operation of the kana-kanji conversion apparatus configured as described above will be described below with reference to the flowchart shown in FIG.

(a)... The kana string inputted by the user through the input device 1 is stored in the input kana string storage section 2.

(b) The following operations are executed in the kana-kanji conversion control unit 3. The kana string is read from the input kana string storage section 2, the word storage section 4 is searched for words whose pronunciation matches part or all of the input kana string, and the grammatical information storage section 5 stores these words. After determining whether or not a correct output string can be constructed using the adjunct word pair information and the connection information between words stored in An input kana string with delimiters inserted at word boundaries and an output character string mixed with kana and kanji are paired and sequentially stored in an output character string storage section 7.

(c)...The kana-kanji conversion control unit 3 prioritizes the set of output character strings stored in the output character string storage unit 7 in (b) using the word information stored in the word usage information storage unit 6. Sort in descending order of degree. A detailed explanation of the sorting procedure is as follows.

First, for all the output character strings stored in the output character string storage section 7, the pronunciations and kanji notations of the independent word portions of the output character strings are extracted. Here, the reading of the independent word part is extracted from the input kana string up to just before the delimiter, and the kanji representation of the independent word is extracted from the output string containing kana and kanji up to just before the delimiter. Furthermore, it is checked whether there is an attached word after the extracted independent word or not, depending on whether there is a kana remaining after the delimiter in the input kana string. Next, for all the output character strings, the word information consisting of the reading of the independent word extracted by the above operation, the kanji notation, and the additional information of the attached word is combined with the word information stored in the word usage information storage unit 6. Perform a comparison to see if there are any matches. At this time, the word information is compared starting from the beginning of the word usage information storage section 6. If the word information does not match, the word information at the next position is compared sequentially, and if the word information matches, the word information is After storing the stored position in the word usage information storage unit 6 in the priority information storage area of the corresponding output character string of the output character string storage unit 7, the word information for the next output character string is compared. Do it like this. In addition, if all word information comparisons are completed and it is found that there is no matching word information, a specific numerical value indicating the lowest priority is stored in the priority information storage area of the corresponding output character string in the output character string storage unit 7. After storing, proceed to comparing word information for the next output string. When the word information match check is completed for all output character strings in this way, the output character strings stored in the output string storage section are finally selected based on the priority information stored in the word information match check. Sort in order from Sorting is performed so that priority information values are arranged in ascending order.

(d)...The output character strings containing kana and kanji characters stored in the output character string storage section 7 are displayed on the display device 8 in order from the first stored character string without delimiters.

(E)... Out of the set of output character strings displayed on the display device 8, a set of output character strings to which the user has given a selection instruction using the input device 1 is stored in the output character string storage unit. The position information is conveyed to the word usage information updating section 9.

(F)...The word usage information update unit 9 recognizes the output character string selected by the user based on the position information in the output character string storage unit 7 obtained in (E), and updates the output character string. (c)
Word information consisting of three items, the reading of the independent word, the kanji notation, and the attached word additional information, similar to that extracted in step 2, is stored at the beginning of the word usage information storage section 6. Note that when storing word information, previously stored word information is moved backward by one word. Further, at this time, if word information has already been stored in all areas of the word usage information storage section 6, the word information at the end is deleted.

By repeating the execution of one kana-kanji conversion from (a) to (kube) above, the word information used is accumulated in the word usage information storage unit 6, and the output character string obtained in the subsequent kana-kanji conversion is This will be used effectively when determining priorities.

The operations have been explained above using the flowchart in FIG. 2, but in order to make the operations more specific, we will focus on the processing performed by the kana-kanji control unit 3 with reference to FIGS. 3 to 7. An example will be explained.

FIG. 3 is a diagram showing the storage state of the word storage unit 4.
It shows the parts in which the reading, kanji notation, and part-of-speech information are stored for words with the readings ``and -saker,'' respectively. FIG. 4 is a diagram showing the storage state of the word usage information storage unit 6, and this also shows the part where word information about independent words with pronunciations of "-sei" and "sei-riki" is stored. 7 to 7 are diagrams showing the storage state of the output character string storage section 7, and show the storage state of the output character string storage section 7 when the input kana string "Seiroku" is subjected to kana-kanji conversion. FIG. 5 shows the memory contents of the output character string storage unit 7 for 100 words after executing the process of flowchart (b).Here, the words shown in FIG. Output character strings determined to be grammatically correct obtained by referring to the information and grammar information storage section 5 are stored. This is a diagram showing the storage state of the output character string storage unit 7 at the time when the match check between the word information stored in the unit 6 and the word information in the output character string is completed, and the priority information storage area is filled with the information in the match check. This shows that the obtained priority information is newly stored. Fig. 7 is a diagram showing the storage state of the output character string storage unit 7 immediately after the execution of the process in flowchart (c) is completed. Indicates that the strings are sorted in order of priority.

Referring again to Figure 5, the output character string for the input kana string "Seika" is "Independent word (Seika) x Adjunct word (
It can be seen that two types of output character strings are obtained: ``Power〉'' and ``Independent word (Seiki)''. On the other hand, from the memory contents of the word usage information storage unit 6 in Figure 4, the pronunciation used in the form with attached adjuncts is -sei, and the words surname and sho are obtained, and no adjuncts are added. It can be seen that the pronunciation used in the pattern consisting of only independent words yields "birthplace" as the saker word.Based on this information, the output character string shown in Figure 5 is determined by the priority. It is sorted in descending order of height and becomes the state shown in Figure 7.Comparing Figures 5 and 7, in the state of Figure 5-, the types of "independent word + adjunct word" and "independent word" are different. Although the output character strings are stored separately, it can be seen that in the state shown in FIG. 7, the output character strings are stored in the order of output character strings related to each type (highest priority).

As described above, according to this embodiment, the word usage information storage unit 6
By storing words that have been used in the past, distinguishing whether they were used in the "independent word + different word" type or in the "independent word" type, kana-kanji conversion can be performed for the input kana string. Even if two types of output character strings are obtained when performing ``independent word ten attached words'' and ``independent word'', the output string with the highest priority will be used regardless of the difference in these types. They can be displayed on the display device 8 in order.

In this embodiment, the word usage information storage unit 6 is configured to give priority to words that have been used recently, but the word usage information storage unit 6 has an “independent” It may also be configured such that words with high frequency of use are given priority, such as distinguishing between two types, ``word + adjunct word'' and ``independent word'', and storing the frequency of use in each type.

Effects of the Invention As described above, the present invention is capable of determining in which of two types a word used in the past was used from a grammatical point of view: "independent word + adjunct word" or "independent word". By storing them separately, even if two types of the same kana string, ``independent word + attached word'' and ``independent word'', are obtained as output character strings for kana-kanji conversion, the difference between these types is eliminated. It is possible to display a set of output character strings in an order that is optimal for the user, regardless of the user, and this has a great practical effect.
