Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a text editing device for creating and editing Japanese texts. In particular, it is used in industrial fields where Japanese word processors have traditionally been used.

(Prior Art) Conventionally, Japanese word processors have been popular as devices for creating and editing Japanese sentences. The Japanese word processor stores and displays character strings containing kanji and kana characters of Japanese sentences input using an input device such as a kana-kanji converter, a voice input kana-kanji converter, or a pen-touch keyboard. It then accesses the stored strings containing kanji and kana to perform editing functions such as inserting, deleting, moving, and replacing strings.

(Problem to be solved by the invention) Conventional Japanese word processors store Japanese sentences only as character strings, so they cannot be inserted or
Editing functions such as deleting, moving, copying, and replacing can only be processed character by character.

On the other hand, when editing Japanese text, inserting and
The units to be processed such as deletion, movement, copying, and replacement are usually structural units of Japanese sentences, such as sentences, clauses, and words, and units that are semantically coherent. In Japanese word processors, users can reconsider a target sentence, clause, word, or other unit as a range of characters, specify the first character position of the range, and the last character position of the range, and then delete it.・Editing operations such as moving and copying will be performed. At this time, it is cumbersome to reconsider the target sentence, clause, word, etc. as a range of character strings, and it also causes the cursor to move back and forth, or the specified position Sometimes I shift the ``by'' by one character. Therefore, it is possible to specify and edit the target in units of sentences, clauses, words, etc.
It is desirable to be able to move the cursor in units of phrases, words, etc.

On the other hand, an English text editing device that allows you to specify units such as words, sentences, and paragraphs for editing was published by Smith et al. in Byte Magazine (Smith, D., Irby, C. , Verplank, B.
and Harslem, E.: “Designing the Star User
Interface”, Byte, Vol. 7, No. 4, 1982). In English, words are separated by spaces, so a string of characters between spaces is considered a “word” and a period is used. A string of characters between (.) can be treated as a "sentence". However, in the case of Japanese sentences, it is not customary to separate words with spaces, so the English method cannot be used as is.

Therefore, in the case of Japanese sentences, there is a method to consider character strings of the same character type as words (Ito, Tanaka: "Editor using Bitmap display and mouse",
``Information Processing'' Vol. 25, No. 8, 1984) and a method of considering the input unit as a clause during kana-kanji conversion input (Japanese Unexamined Patent Application Publication No. 1982-69829 ``Document Creation Device''), but these The method is only an approximation and lacks accuracy. For example, when we adopt a method of treating strings of the same glyph type as words, for the sentence ``Since then he has pursued a new method.''
Words such as ``method'' and ``pursuit'' can be specified well, but ``since'' and ``he'' cannot be separated, resulting in ``since he'', and ``new'' can only be specified with ``new''. When inputting kana-kanji conversion input using a method that considers the input unit as a clause, for example, when inputting ``letter'', ``hand'', ``paper'', and ``wo'' are used.
If you input ``letter'' separately, or if you input ``letter'' and later modify ``ni'' to ``wo,'' you will no longer be able to treat ``letter'' as a single phrase.

Furthermore, in conventional character string editing, it is not possible to specify the part of speech of a word, resulting in incorrect processing. For example, when trying to replace the noun ``repetition'' with the noun ``repetition,'' the conventional method uses ``repetition'' that appears as a noun in a sentence (for example, ``repetition'' of the same word has the effect of emphasis. ``repetition'') as well as ``repetition'' in the conjunctive form of the verb.
(For example, ``repetition'' in ``The same word is 'repeated' over and over again.'') is subject to substitution, so the disadvantage is that the result is a sentence that does not make sense (for example, , "It's 'repeated' over and over again." becomes "It's 'repeated' over and over again."

The purpose of the present invention is to eliminate the drawbacks of conventional character string editing as described above, and to provide accurate and easy-to-operate editing based on sentence structure information such as units of sentences, clauses, and words, and parts of speech of words. The object of the present invention is to provide a text editing device that enables the following.

(Means for Solving the Problems) The present invention provides a text editing device for editing Japanese texts, which includes a text storage means for storing character strings containing kanji and kana characters of Japanese texts to be edited, and a word dictionary. a dictionary storage means for storing, and a sentence for determining sentence structure information such as units of sentences, clauses, and words and parts of speech of each word for the kanji-kana-mixed character string stored in the sentence storage means by referring to the word dictionary; an analysis means, a sentence structure storage means for storing the sentence structure information determined by the sentence analysis means, a structure designation means for specifying the sentence structure information, and a sentence structure storage means specified by the structure designation means. A text editing device is characterized in that it includes a structural position extracting means for extracting a position in a text based on text structure information.

(Example) The structure and operation of the present invention will be explained using the drawings.

FIG. 1 is a block diagram showing the configuration of an embodiment of the text editing device of the present invention.

In FIG. 1, the input means 1 inputs a character string containing kanji and kana in a Japanese text, inputs editing commands such as insertion, deletion, movement, copying, and replacement, and inputs a command to move the cursor position. keyboard,
A voice input device or the like is used in combination with a kana-kanji conversion device.

The text storage means 2 stores the character string containing kanji and kana characters inputted by the input means 1. IC memory, magnetic disk devices, etc. are used.

The display means 3 displays the kanji/kana mixed character string stored in the text storage means 2, a cursor, and the like. A CRT display or the like is used.

The dictionary storage means 4 stores a word dictionary. I C
Memory, magnetic disk devices, etc. are used. A word dictionary registers at least the notation and part of speech for Japanese words (here,
(assuming that the notation is registered as a heading).

The sentence analysis means 5 refers to the word dictionary stored in the dictionary storage means 4 and analyzes the kanji-kana-mixed character string stored in the sentence storage means 2, including units of sentences, clauses, and words, and parts of speech of each word. Determine the sentence structure information of. The dictionary storage means 4 and the sentence analysis means 5 are known means, such as "Japanese dictionary storage and automatic segmentation of Japanese sentences" (Nagao, Tsujii, Yamagami, Takebe,
``Information Processing'' Vol. 19 No. 6, 1978).

The sentence structure storage means 6 stores the sentence structure information of the kanji/kana mixed character string determined by the sentence analysis means 5. IC memory, magnetic disk devices, etc. are used. As the sentence structure information, specifically, the position of sentence boundaries, the position of clause boundaries, the position of word boundaries, the part of speech of each word, etc. are stored.

The structure specifying means 7 specifies sentence structure information.
A keyboard or the like is used, and the input means 1 can also be used. Specifically, the contents to be specified are as follows.
These include units such as sentences, clauses, and words, their numbers, and types of parts of speech. For example, to specify units such as sentences, clauses, and words, keys such as "sentence,""clause," and "word" may be prepared. The number can be specified using the numeric keypad, or by increasing or decreasing the number using the "+" or "-" keys. The part of speech of a word can be specified by determining a code corresponding to the part of speech and inputting that code.

The structure position extraction means 8 refers to the sentence structure storage means 6 and extracts a position in the sentence based on the sentence structure information. Specifically, upon receiving the current cursor position and the designation by the structure designation means 7, the sentence structure storage means 6 is searched and the corresponding character position or range is extracted. Or, given a string range,
Extract the part-of-speech code corresponding to that range.

The text editing control means 9 realizes editing functions such as insertion, deletion, movement, copying, and replacement by exchanging information with each of the above-mentioned means. Conventional text editing devices are
It is composed of only an input means 1, a text storage means 2, a display means 3, and a text editing control means 9, and the text editing control means 9 performs, for example, the following processing.

(1) Insert and write the kanji-kana-mixed character string sent from the input means 1 into the text storage means 2. The writing position is the character position corresponding to the cursor position.

(2) The character string containing kanji and kana characters stored in the text storage means 2 is displayed on the display means 3. The cursor is also displayed at the same time.

(3) The cursor position displayed on the display means 3 is changed in accordance with the cursor movement command sent from the input means 1.

(4) Receive the first character position and last character position of the range sent from input means 1, and display the character string between them in a different display method from the normal character string (for example, by displaying it in reverse video) ).

(5) When a "delete" command is sent from the input means 1, the character string corresponding to (4) is deleted from the text storage means 2 (accordingly, the display on the display means 3 is also changed). ).

(6) When a "move" command is sent from the input means 1, the character string corresponding to (4) is deleted from the text storage means 2 and stored in the buffer in the text editing control means 9 ( Along with this, the display on the display means 3 is also changed).

(7) When a "copy" command is sent from the input means 1, the character string corresponding to (4) is copied from the text storage means 2 to the buffer in the text editing control means 9.

(8) When the movement destination/copy destination position is sent from the input means 1, insert the buffer contents in the text editing control means 9 into the position of the text storage means 2 corresponding to the movement destination/copy destination position. (Accompanying this, the display on the display means 3 is also changed).

(9) When a "replace" command, a character string to be replaced, and a character string to be replaced are sent from the input means 1, the character string to be replaced is searched from the text storage means 2, and the character string to be replaced is found. If so, replace it with the replacement string.

In addition to the processes (1) to (9) above, the text editing control means 9 in the text editing apparatus of this embodiment includes a text analysis means 5, a text structure storage means 6, a structure specification means 7, a structure position extraction means 8 The following operations are performed by controlling the operation of the

(10) A character string is written to the text storage means 2,
When a character string in the text storage means 2 is changed, the position of the character string is notified to the text analysis means 5, the text analysis means 5 is caused to analyze the character string, and the contents of the text structure storage means 6 are changed. (The contents of the sentence structure storage means 6 always correspond to the contents of the sentence storage means 2).

(11) Specify units such as “sentences”, “clauses”, and “words” from structure specifying means 7 (including specifying the number of units)
is sent, the current cursor position and its unit specification are sent to the structure position extraction means 8, and the first and last character positions of the corresponding character string range are received from the structure position extraction means 8. . Next is the process (4).

(12) At the time of (9), if the part-of-speech code is sent from the structure specifying means 7, the position of the replaced character string found from the character storage means 2 is sent to the structure position extraction means 8, and the structure position The corresponding part-of-speech code is received from the extraction means 8. Structure designation means 7
When the part-of-speech code input from the part-of-speech code and the part-of-speech code received from the structural position extraction means 8 match, the same replacement process as in (9) is performed.

Next, the operation of this embodiment will be explained using an example.

First, it is assumed that the following sentence is input by the input means 1.

Previously, Word Processor Sa creates and edits texts. As a device for collecting It is widespread. word Lower cost of processors However, progress is being made. War doprocessor is a sentence memorize and display.

The text editing control means 9 receives this character string from the input means 1 and writes it into the text storage means 2. Then, the text analysis means 5 is further activated to analyze the character string written in the text storage means 2.
The text analysis means 5 reads the character string stored in the text storage means 2 and writes the text structure information resulting from the analysis into the text structure storage means 6.

FIG. 2a shows the contents of the sentence storage means 2 for this example, and FIG. 2b shows the contents of the sentence structure storage means 6 for this example. The positions of the elements in the matrices a and b in FIG. 2 correspond. In Figure 2b, the position where s is written indicates that that position is the first character position of a sentence (and also the first character position of a clause), and the position where p is written indicates that position. indicates that it is the first character position of the clause. Positions where other values are written indicate the first character positions of the word, and the values represent the part of speech of the word as follows.

Name: Noun Verb: Complement: Auxiliary verb Head: Prefix Suffix: Suffix Particle: Particle Dot: Punctuation mark However, the method of realizing the sentence structure storage means 6 is not limited to that shown in FIG. 2b. For example, instead of creating a matrix corresponding to a as shown in Figure 2b, sentence initial positions (0,0), (3,7), (5,8), phrase initial positions (0,0), (0,3 ), (1,3), (1,6),...
,
(7,5), word (0,0, name), (0,2, points),
(0,3, name), ..., (7,5, motion), (7,9, points)
This can also be achieved by enumerating the positions.

Here, it is assumed that an operation is performed to delete the sentence ``The price of word processors is decreasing.''

The conventional method of deleting a string is to first position the cursor at the "wa" position, press the "start" key,
Next, position the cursor at the "." position and click "End".
Specify the statement to be deleted by pressing the key (then press the "Delete" key to specify deletion of that statement).

In contrast, in the method of this embodiment, by pressing the "Sentence" key while the cursor is at an arbitrary position in the sentence "Word processors are becoming cheaper." , the sentence to be deleted can be specified (then pressing the "Delete" key is the same).

How each component operates at that time will be described next.

Suppose that the cursor is at the ``value'' position and the ``sentence'' key is pressed. The "sentence" key is input from the structure specifying means 7 and sent to the text editing control means 9. The text editing control means 9 controls the current cursor position (4,
7) and the designated structural unit "sentence" are sent to the structural position extraction means 8.

The structure position extracting means 8 refers to the sentence structure storage means 6, and extracts the closest s in front of the position (4, 7) (representing the top position of the book as described above) and the position behind the position (4, 7). Find the nearest s. As a result, positions (3, 7) and (5, 8) are obtained. Then, the position (3, 7) is sent as the start position of the character string range, and the position (5, 7) one character ahead as the end position is sent to the text editing control means 9. In response to this, the text editing control means 9 edits the character string from position (3, 7) to position (5, 7) as follows.
The display means 3 is instructed to change the display method from that of other character strings, for example, to display the character string in reverse video.

Subsequently, the "delete" key is input from the input means 1 and sent to the text editing control means 9. In response to this, the text editing control means 9 deletes the character string from position (3, 7) to position (5, 7) in the text storage means 2, and deletes the character string from position (5, 8) onwards. Move up to position (3,7). Then, the text analysis means 5 is further activated, and the text structure information corresponding to the content of the text storage means 2 is transferred to the text structure storage means 6.
write to. As a result, the contents of the sentence storage means 2 and the sentence structure storage means 6 become as shown in FIGS. 3a and 3b.

In this way, the deletion of "sentence" units has been realized, but when it is "sentence" units, s in the sentence structure storage means 6 is deleted.
Instead of searching for the position of p, it is sufficient to search for the position of p, and when the unit is a "word", it is sufficient to search for the position containing the part of speech. Structure position extraction means 8
However, after returning the character string range corresponding to the structural unit to the text editing control means 9, the processing of the text editing control means 9 is similar to conventional processing, so it not only "deletes" the structural unit but also deletes the structural unit. "Move" and "Copy" units
It is clear that "replacement" and "cursor movement" can be realized in the same way.

(Effects of the Invention) As explained above, according to the present invention, editing is performed in units of sentence structure such as "sentences,""clauses," and "words," or editing is performed based on part-of-speech information. becomes possible.

In the case of conventional character string editing, it was necessary for humans to reconsider what they were thinking in their heads as a range of character strings, and then perform the editing operation. The object can be specified naturally, and the operability of the text editing device is greatly improved.

Compared to the conventional method of specifying character strings of the same character type and the method of specifying input units for Kana-Kanji conversion input, the units of words, clauses, and sentences that can be specified using this method are It is much more accurate, and it is extremely easy for the user to specify what to edit.

Furthermore, not only the structural unit of a sentence but also the part of speech of a word can be used as information during editing, which improves the accuracy of editing such as substitution compared to the past.
