Abstract

PURPOSE:To provide a character string retrieving device capable of retrieving and specifying a Japanese character string by the input of a HIRAGANA (cursive form of Japanese syllabary) input. CONSTITUTION:A HIRAGANA string is inputted to an input operation part 11 as a retrieving key. A notation reading converting part 14 divides a character string to be retrieved which is stored in a retrieved character string storing part 13 in each word and allows the reading to correspond to respective words. A character string retrieving part 12 successively retrieves the reading of the character string to be retrieved which is made to correspond to respective words by the converting part 14 by using the character string inputted from the input operation part 11 as a retrieving key. When the retrieval succeeds, an output part 16 specifies the retrieving key concerned and displays the retrieved character string.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A character string searching device according to the present invention will be described below based on embodiments. (First Embodiment) FIG. 1 is a block diagram of a first embodiment of a character string search device according to the present invention. The character string search device according to the present embodiment includes an input operation unit 11 that inputs a search key (keyword), a character string search unit 12 that searches for a character string based on the search key input from the input operation unit 11, The search target character string storage unit 13 that stores the search target document, the notation reading conversion unit 14, the notation reading storage unit 15, and the output unit 16 are provided.

In the input operation section 11, an operator inputs a hiragana as a search key. The input search key is notified to the character string search unit 12. The search target character string storage unit 13 stores a search target Japanese kanji kana mixed sentence created by a word processor or the like. The notation reading storage unit 15 stores the heading notation 21, the word notation 22, and the reading 23 in association with each other as shown in FIG. 2 as an example. The “selection” mentioned in the heading notation 21 on the first line is the word notation 22 “selection” and the reading 23 “sentaku”.

The notation reading conversion unit 14 includes a character string search unit 12
When the activation notification is received from, the kanji / kana mixed sentence stored in the search target character string storage unit 13 is read. Morphological analysis is sequentially performed from the beginning of the read sentence to extract a character string. When the extracted character string includes Chinese characters, the heading notation 21 of the notation reading storage unit 15 that matches the extracted character string.
To search. When the matching headline notation 21 is detected as a result of the search, the character string is recognized as one Japanese word, the word notation 22 and its reading 23 are extracted from the notation reading storage means 15, and the word and its The reading is associated with and stored in the temporary storage unit. For example, the search target character string storage unit 1
When the Japanese sentence “Ama Teneru Maeru Autumn” as shown in FIG. 3 is stored in 3, the temporary storage unit of the notation reading conversion unit 14 stores the content as shown in FIG. There is. Here, each symbol of Wn (a, b); has the following meanings. “W” represents a word, “n” represents the order of recognized words, “a” represents a recognized word, “b” represents the corresponding reading, and “;” represents a word delimiter.

The notation reading conversion unit 14 determines whether or not the reading of the sentence stored in the search target character string storage unit 13 is completed, and when the reading is completed, as shown in FIG. 4, it is stored in the temporary storage unit. The character string search unit 12 is notified while the stored word and its reading are associated. Character string search unit 12
Determines whether or not the hiragana input as a search key from the input operation unit 11 is present in the Japanese sentence to be searched (search target character string) notified from the transcription reading unit 14. The search for the search character string is performed by sequentially shifting the characters from the beginning of the search target character string backward by one character and checking whether or not the search key exists. When present in a Japanese sentence, the word (Wn (a, b)) associated with the corresponding reading (symbol b) is extracted, and the sentence and the notation character position in the sentence are output to the output unit 16. Notice. If it does not exist, the output unit 16 is notified of the search failure.

For example, when "Uma" is notified as the search key, the corresponding word notation "horse" 41 (FIG. 4) is present in the Japanese sentence "Tenko Ma Furu Aki".
The notation character position is notified in the format of "start notation character position, end notation character position". In this case, it is "4, 4", which means that it occupies the fourth character to the fourth character in the Japanese sentence.

The output unit 16 receives the notification of the Japanese sentence and the written character position from the character string search unit 12, displays the Japanese sentence on the display screen, and displays the character corresponding to the written character position in a shaded manner, for example. Or, and the search result is displayed. When the notification of the search failure is received, the search failure is displayed on the display screen. Next, the operation of this embodiment will be described with reference to the flowchart shown in FIG.

First, the operator inputs a hiragana string which is a search key, for example, "horse", from the input operation unit 11 (S502). It is not necessary to convert Hiragana to Kanji. The input operation unit 11 notifies the character string search unit 12 of the search key, and the character string search unit 12 notified of the search key activates the notation reading conversion unit 14 (S504). The notation reading conversion unit 14 reads out the Japanese sentence stored in the search target character string storage unit 13, performs morphological analysis, and extracts a character string (S506).

When the extracted character string includes Kanji,
The heading notation in the notation reading storage unit 15 is searched, and the word notation and its reading are associated and stored in the temporary storage unit. When the extracted character string does not include a kanji, the word notation and its reading are stored as they are in the temporary storage unit (S508). The notation reading conversion unit 14 determines whether or not the reading of the sentence stored in the search target character string storage unit 13 is completed (S510), and if not completed, S506.
If it is completed, the process proceeds to S512.

When the sentence stored in the search target character string storage unit 13 is as shown in FIG. 3, the contents shown in FIG. 4 are stored in the temporary storage unit. Next, the notation reading conversion unit 14
Displays the content temporarily stored in the temporary storage unit in the character string search unit 12
(S512). The character string search unit 12 searches whether or not the search key “horse” exists in the content notified from the notation reading conversion unit 14 (S514). When the "uma" exists, the display character position in the search target sentence of the "uma" is notified to the output unit 16 together with the search target sentence (S).
516).

The output unit 16 receives the notification of the display character position "4, 4" from the character string search unit 12 and the sentence "Autumn rich in the sky" and displays the fourth character "horse" on the display screen. The display attributes are displayed in a shaded display, for example (S518). (Second Embodiment) FIG. 6 is a block diagram of a second embodiment of the search device according to the present invention.

The search device according to the present embodiment has an input operation unit 11
And the character string notation reading conversion unit 64 and the notation reading storage unit 15
And an output unit 16 and a search target reading character string creation unit 67. Each unit having the same configuration as that of the search device of the first embodiment is designated by the same reference numeral and its description is omitted.

In addition to the configuration of the first embodiment, the notation reading conversion unit 64 associates the words stored in the temporary storage unit with the reading object reading character string creation unit 67 with their readings, and sets the contents thereof. Notice. Upon receiving the notification of the character string in which the word and its reading are associated with each other, the search target reading character string creation unit 67 decomposes the character into a character unit in order from the first word. The decomposed reading character (corresponding to the symbol "b" described in the first embodiment) and the symbol indicating the order of words to which the reading character belongs (corresponding to the symbol "Wn" described in the first embodiment). The reading target reading character string is created by sequentially concatenating the reading characters from the beginning and notifies the character string searching unit 62. In the case of the search target Japanese sentence shown in FIG. 3 of the first embodiment, the search target reading character string is “Tentaku Umakoeraki”, and the word to which the associated reading character belongs is The symbol (the combination of notation and reading) is "W1W1W2W2W2W3W3W
4W4W4W5W5 ".

In addition to the character string retrieving unit 12 of the first embodiment, the character string retrieving unit 62 notifies from the notation reading conversion unit 64 and the retrieval object reading character string creating unit 67 and the retrieval object reading character string You will be notified with a symbol that represents the word to which the reading character belongs. The search target reading character string is shifted one character at a time from the beginning to the rear, and it is checked whether or not a search key is present. If there is, a symbol representing the word to which the related reading belongs is extracted. Based on the symbol, the notation character position of the search target character string is obtained after referring to the association (exemplified in FIG. 4) notified from the notation reading conversion unit 64.

Next, the operation of this embodiment will be described with reference to FIG. First, the input operation unit 11 waits for an input of a search key from the operator, for example, a hiragana character string “Umakoe” (S702). Next, the same operations as S501 to S510 described in the first embodiment are performed, and the contents temporarily stored in the notation reading conversion unit 64 are notified to the character string search unit 62 and the search target reading character string creation unit 67 ( S704).

The retrieval target reading character string creating unit 67 decomposes the notified readings in word units into character units, and associates the characters of the decomposed readings with symbols indicating the order of the words before decomposition, The decomposed reading characters are sequentially connected and notified to the character string search unit 62 (S706). The character string searching unit 62 notifies the search target reading character string creating unit 67 of “Tentaku Umaeru Aki” and “W1W1W2W2W2W3W3”.
"W4W4W4W5W5" is sequentially searched by shifting one reading character from the start position of the search target reading character string, and it is determined whether a search key exists (S708).

Since "Umakoe" exists in the search target reading character string, the symbol "W3W3W4W4" representing the word to which the associated reading character belongs is extracted. It is checked whether the corresponding word notation “horse” of W3 and the word notation “rich” of W4 shown in FIG. Since it is the first character, the output unit 16 is notified of "4, 7" (S7).
10).

The output unit 16 displays "Autumn fertilizing autumn" on the display screen, and the display of the "Horse fertilizing" portion is shaded (S712). When it is determined that the search key does not exist (S708), the output unit 16 displays the search failure display on the display screen (S712). (Third Embodiment) The character string searching device according to the present embodiment has substantially the same configuration as the character string searching device according to the second embodiment, but the contents stored in the notation reading storage unit 15 are shown in FIG.
As shown in FIG. 2, it differs from that of the second embodiment (FIG. 2).

The notation reading storage unit 15, as an example of which is shown in FIG. 8, has a heading notation 81 for each word, a notation 82 for each character forming a word, and a reading 8 for each character.
3 is stored in association with each other. As described above, as a result of different contents stored in the notation reading storage unit 15, the notation reading conversion unit 6
In 4, the reading is associated with each character that constitutes the search target character string stored in the search target character string storage unit 13. In Fig. 9, the search target character string is "Autumn fertile autumn."
Shows the contents associated with the reading for each character in the notation reading conversion unit 64.

The meaning of each symbol of Cn (a, b) shown in FIG. 9 is that "C" is a character, "n" is the order of recognized characters, "a" is a recognized character, and "a" is a recognized character. "b" is the corresponding reading, and ";" is a character delimiter. Upon receiving the notification from the notation reading conversion unit 64, the search target reading character string creation unit 67 divides the reading of the search target notation character string that is divided into characters and is associated with the reading from the beginning into character units.
The decomposed reading characters and the symbols (between the notation and the reading) representing the characters to which the reading belongs are associated with each other, and the decomposed reading characters are sequentially connected to create a search target reading character string.

In the present embodiment, the retrieval target reading character string is "Tentaku Umakoeraki", and the set of notation and reading is "C1C1C2C2C3C4C4C5C6C7C8C.
8 ". The character string search unit 62 searches and determines whether or not the search key input from the input operation unit 11 exists in the search target reading character string notified from the search target reading character string creating unit 67. When it is determined that it exists,
The notation position in the search target character string in which the search key exists is determined from the associated notation and reading combination. The notation position is determined in character units, unlike the second embodiment. Since the searched character string "Umakoe" is associated with "C2C2C3C4", the corresponding character units "horse", "man" and "e" are the fourth to sixth characters of the search target character string. It is required to occupy. The output unit 16 is notified of “4, 6”.

The operation of this embodiment is S508 of the second embodiment.
And S706 are associated with the reading in character units, the notation character position notified to the output unit 1 in S710 is "4, 6", and the "horse riding" portion is shaded in S712. The description is omitted because there is no difference from the second embodiment except that only the hanging display is different. (Fourth Embodiment) The character string search device of the present embodiment is basically the same as the character string search device of the first embodiment in terms of basic structure, and therefore the additional structure of the first embodiment will be described. .

When the number of characters in the search key does not match the number of characters in the word corresponding to the searched character string, the character string search unit 12 reads the corresponding word from the beginning and the character in the search key. If the columns are compared and they do not match, the output unit 16 is notified of the search failure. Next, the operation of this embodiment will be described with reference to FIG.

First, the search key "MA" is input from the input operation unit 11.
Is input (S502). Since S504 to S512 are the same as the operation of the first embodiment, description thereof will be omitted. In step S514, the character string search unit 12 sequentially searches the reading of the search target character string notified from the notation reading conversion unit 14 from the beginning, and determines that the search key “MA” exists. Although the word W3 (horse, horse) corresponding to the character string "MA" is obtained, the character number "2" of the word corresponding to the character number "1" of the search key does not match. Further, since the reading "U" from the beginning of the corresponding word "horse" and the character string "MA" of the search key do not match, the output unit 16 is notified of the search failure.

In this case, it is assumed that the search key "U" is input in S502. In S514,
The word W3 (horse, horse) corresponding to the character string "U" is obtained, and the character number "1" of the search key does not match the character number "2" of the corresponding word. However, in this case, since the reading "u" from the beginning of the corresponding word "horse" and the character string "u" of the search key match, it means that the word "horse" has been searched, and the output unit 16 Is notified of "4, 4". (Fifth Embodiment) FIG. 10 is a block diagram of a character string designating device according to a fifth embodiment of the present invention.

The character string designating apparatus of this embodiment comprises an input operation unit 100, an input character string temporary storage unit 101, a character string search unit 102, a designated character string storage unit 103, and a notation reading conversion unit 104. And the notation reading storage unit 15 and the output unit 16
And the designated target reading character string creation unit 107 and the list storage unit 1
08, a list display unit 109, and a character string complementing unit 110.

The input operation unit 100 receives an input of a designated character string from the operator in hiragana and stores the input character string in the input character string temporary storage unit 101. In addition, the character string search unit 102 is notified of the input. The input of the designated character string does not need to be made temporary to specify one designated target string from a plurality of designated target strings,
You can add and enter. Also, the operator
The list display unit 109 selects and inputs the number given to the designated character string. The input number is notified to the character string complementing unit 110.

The input character string temporary storage unit 101 temporarily stores the input character string. In addition, the character string complement unit 11
By 0, the character string can be additionally stored in the temporarily stored content. The character string search unit 102 is the input operation unit 100.
In response to the notification that the designated character string has been input, the notation reading conversion unit 104 is activated. A notification of the word notation 22 and the corresponding reading 23 is received from the notation reading conversion unit 104, and at the same time, a notification of the designation target reading character string associated with the set of words to which the reading belongs from the designation target reading character string creation unit 107. Receive. When receiving this notification, the designated character string stored in the input character string temporary storage unit 101 is used as a search key.
Search for the designated reading string. When the search key exists in the designated target reading character string, the list storage unit 108 stores a designated target character string pair which is a set of the designated target character string and the designated target reading character string.

The designated character string storage unit 103 stores a plurality of designated character string pairs. Notation reading conversion unit 104
Receives a notification from the input operation unit 100, and sequentially reads the designation target character strings stored in the designation target character string storage unit 13. When one designation target character string is read, the heading notation 21 of the notation reading storage unit 15 is searched, and when a Japanese word that matches the character string is detected, the character string is regarded as one Japanese word. recognize. And the word notation 2
2 and the reading 23 corresponding to the word notation 22 are extracted from the notation reading storage unit 15, and they are associated with each other and notified to the character string search unit 102 and the designated target reading character string creation unit 107.

The notation-reading conversion unit 104 determines whether or not all the designated character strings stored in the designated character string storage unit 103 have been read. When it is determined that all of them have been read, the list display unit 109 is notified of the completion of reading. Upon receiving the notification of the associated word notation and reading from the notation reading conversion unit 104, the designated target reading character string creation unit 107 decomposes the reading of the designated target character string into character units from the beginning of the character string. The decomposed phonetic characters are associated with the set of words (notations) to which the phonetic characters belong, and the decomposed phonetic characters are sequentially connected to create a designated reading character string. The created designated target reading character string is associated with the set of words to which the reading belongs and is notified to the character string search unit.

The list storage unit 108 includes a character string search unit 102.
The designated target reading character string pair searched by is stored. When the list storage unit 109 receives the read completion notification from the notation reading conversion unit, the list storage unit 109 reads the stored content of the list storage unit 108, displays the retrieved designated target character string, and causes the character string complement unit 110 to display the searched target character string. Notify the display. Further, it is determined whether or not a plurality of designation target character strings are in the relationship of homophones and different characters by referring to a dictionary in which character codes (not shown) and their readings are associated with each other. The designation target character strings stored in the list storage unit 108 are numbered and displayed.

The character string complementing unit 110 is a list storage unit 109.
When the display notification is received from, the designation target character string stored in the list storage unit 108 is read and it is determined whether or not the number is 1. When the number is 1, the output unit 16
Notify the specified character string to. When the number is 2 or more, the common part from the beginning of the designated character string to be read is extracted, and the character string is additionally stored in the storage content of the input character string temporary storage unit 101, and the designated character string storage unit is also stored. The stored content of 103 is updated to the designated character string stored in the list storage unit 108. When the notification of the number is received from the input operation unit 100, the designation target character string corresponding to the number stored in the list storage unit 108 is extracted and notified to the output unit.

The notation reading storage unit 15 has the same configuration as the notation reading storage unit of the first embodiment. The output unit 16 receives the notification of the designated character string from the character string complement unit 110, and displays the designated character string on the display screen. Next, the operation of this embodiment will be described with reference to FIG.

It is assumed that "selection", "laundry", and "election" are stored in the designated character string storage unit 103,
"Selection" is specified from these specification target character strings. First, the operator inputs the hiragana character string “se” from the input means 11 (S1102). The input character string is stored in the input character string temporary storage unit 101. The notation reading conversion unit 104 reads out one designation target notation character string stored in the designation target character string storage unit 103 (S11).
04).

The notation reading conversion unit 104 extracts some character strings from the head side of the read character string, and the Japanese words matching the extracted character strings are the headings of the notation reading storage unit 15 shown in FIG. Search whether or not it exists in the notation. When the matching Japanese word is detected, the character string is recognized as one Japanese word, and the reading for the word notation is extracted from the notation reading storage unit 15.

The designation target character string divided into word units and the reading of the character string are notified from the notation reading conversion unit 104 to the character string search unit 102 with the word and its reading associated with each other. The content of the notification is “W1 (selection, selection);”
Is. The meaning of each symbol of Wn (a, b) is that "W" is a word, "n" is the order of the recognized words, "a" is the recognized word, and "b" is the corresponding reading. , “;” Indicates word division (S1106). Next, the designated target reading character string creation unit 107 divides the reading of the designated target written character string divided into words and associated with the reading into character units from the beginning of the character string (S1108). The decomposed reading characters are associated with the notation and the reading group to which the readings belong, and the decomposed reading characters are sequentially connected to create a designation target reading character string (S1110). The combination of notation and reading associated with the designated reading text string is "Select"
Are "Sentaku" and "W1W1W1W1". The character string search unit 102 searches for the designated target reading character string using the character string “SE” input from the input operation unit 100 as a search key, and determines whether or not the character string “SE” begins. To do. When it is determined that it has started,
A designated target character string pair, which is a pair of the designated target written character string and the designated target reading character string, is added to the list storage unit 108 (S11).
12). Until the number of designation target notation character strings stored in the designation target character string storage unit 103 becomes 0, S1104 to S
1112 is repeated (S1114). Therefore, S1
In 106, the character string search unit 102 displays “W2 (laundry,
W3 (election, class); ”is notified. In S1110, "Washing" is "Sentaku" and "W2".
"W2W2W2", "Election" is "Senkyo" and "W3
"W3W3W3", respectively, is a set of notation and reading associated with the designated target reading character string.

Since "selection", "laundry", and "election" all start with "se", when the number of character strings stored in the designated character string storage unit 103 becomes 0, the list storage unit 1
The designated character string pairs stored in 08 are “selection, selection”, “laundry, selection” and “election, selection”.
Become one The list display unit 109 displays the contents stored in the list storage unit 108. At this time, words with the same phonetic variants such as "Sentaku" are displayed with numbers according to the order stored in the list storage unit 108 (S1116). If the number of designated target character string pairs stored in the list storage unit 1078 is 1, the character string complement unit 110 notifies the output unit 16 of the designated target character string pairs (S1118). When the number is 2 or more, the common part from the beginning of the designated target reading character string is extracted, the contents of the input character string temporary storage unit 101 are updated, and the designated target written character string stored in the list storage unit 108 is updated. Is moved to the designated character string storage unit 103 8S11
20). Since the reading character string “Sen” from the first character to the second character is a common part, “n” is newly stored in the input character string temporary storage unit 101. In addition, the operator is
Returning to S1102, the character string to be added to the “pen” stored in the input character string temporary storage unit 101 is input from the input operation unit 100. When “ki” is input, the content stored in the input character string temporary storage unit 101 is changed to “sense”. Again, the operation is continued until the number of designation target notation character strings stored in the designation target character string storage unit 103 becomes 0 (S1104 to S1112). At this time, when the input character string is “Senki”, the designated target character string pair stored in the list storage unit 108 is “election, Senkyo” only 1
Therefore, the output unit 18 displays this on the display screen (S1126). Further, when “ta” instead of “ki” is additionally input from the input operation unit 100 when returning to S1102, the content stored in the input character string temporary storage unit 101 is changed to “Senta”. It

Then, through S1104 to S1112,
When the number of designation target notation character strings stored in the designation target character string storage unit 103 becomes 0, the list storage unit 108
There are two designated character string pairs stored in “selection, text” and “wash, text”. Since these two words have the same phonetic variant, it is not possible to reduce the number of candidates by adding more hiragana characters.

For this reason, the character string complementing unit 110 is input by the operator from the input operation unit 100 with the number added by the list display unit 109 (S1124). Since this number represents the order in which homophones are stored in the list storage unit 108, the output unit 16 displays the designated character string pair selected according to the input number on the display screen (S112).
6). For example, if "1" is input, "selection, selection" is displayed, and if "2" is input, "washing, selection" is displayed.

This embodiment can be used as a document name designating device when writing or reading a document in a document processing device. In this embodiment, if the document name stored in the auxiliary storage means such as a floppy disk is stored in the designation target character string storage unit 103, the document name can be designated by hiragana input. Although the characters input by the operator from the input operation unit 11 or the input operation unit 100 are hiragana in the first to fifth embodiments, the input operation unit may be provided with a katakana / hiragana conversion mechanism for katakana input. Alternatively, an alphabet / hiragana conversion mechanism may be provided for alphabet input.

Similarly, although the search target character string is a Japanese sentence, it may be a Chinese sentence, and an alphabet or a phonetic symbol may be adopted as a search key, and a necessary conversion mechanism may be additionally provided.
