DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a keyword creating device,
In particular, the present invention relates to a keyword creating apparatus suitable for creating keywords used for high-speed search of text stored in a CD-ROM by direct access.

[0002]

2. Description of the Related Art Various publications, including dictionaries, are on CDs.
-Published and stored in ROM. This CD-
In ROM publications, direct access is generally performed using search words (keywords) in order to quickly search the contents (explanatory text, commentary text) of stored text. As shown conceptually in FIG. 12, this keyword is created by extracting a large number of nouns as search word candidates from text data to be stored in a CD-ROM to create keyword data. , A keyword suitable as a search word is determined, and the keyword is recorded on a CD-ROM together with text such as a sentence to be a publication.

[0003] Conventional keyword creation uses a keyword extraction system that uses a natural language processing system to extract all nouns from text data with kana (reading) assigned, and can be used as keywords from the noun data. There is an operation of creating keyword data having a characteristic and performing a review or correction on the keyword data to determine only a noun suitable as a search word, thereby using the noun as a keyword.

[0004]

However, depending on the keyword extraction system, many nouns that are not correct as Japanese or unsuitable as search words are extracted from text data, and the extracted words appear in the text data. Because all are displayed in order, if there are multiple identical search word candidates, it is unknown whether or not they have already appeared. In addition, since it is difficult to match the review and correction at that time, there is a problem that the work of proofreading (reviewing) and correction performed until the final keyword is created from the keyword data is excessively loaded.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems. Even when a plurality of identical search word candidates are included in keyword data extracted as search word candidates from text data, review and correction are performed. An object of the present invention is to provide a keyword creating device that can perform tasks efficiently and improve the efficiency of keyword creating work.

[0006]

The present invention provides a CD-ROM.
A search term candidate extracted from text data for CD-ROM with reference to a keyword dictionary in which a noun that may become a search term for words and its reading are registered, and the search word candidate read from the keyword dictionary A keyword creating device that displays keyword data including readings on a display, and reviews and corrects the keyword data on the display to create a keyword suitable as a search word,
When a plurality of identical search word candidates are included in the keyword data, a configuration is provided that has a function of distinguishing and displaying a new search word candidate that appears first on the display and a search word candidate that appears second and subsequent times. Thus, the above problem has been solved.

According to the present invention, the keyword creating apparatus is provided with a function of reflecting a result of correcting a new search word candidate to an already-examined search word candidate and a function of correcting only a selected previously-examined search word candidate. The configuration is as follows.

According to the present invention, in the keyword creating apparatus, there is provided a function of displaying a search word candidate on a display in comparison with a text containing the search word candidate. .

[0009]

According to the present invention, when a plurality of identical search word candidates are included in the keyword data extracted from the text data, the keyword creation device determines whether the new search word candidate appears first on the display and the second search word candidate. Since it is displayed so as to be distinguished from the existing search word candidates that appear thereafter, it is possible to clearly distinguish new and existing same search word candidates on the display and recognize them. Even if it is necessary to review and correct each time, it is possible to refer to the results of the review and correction for the new search word candidate and make the review and correction consistent, so that the work can be performed efficiently and accurately. Can be performed.

Further, in the present invention, when a function for reflecting the result of correcting a new search word candidate to an already-examined search word candidate and a function for correcting only the selected already-examined search word candidate are provided. For the same search word candidate, it is only necessary to review and correct the new search word candidate only once, so that the efficiency of the review and correction work can be greatly improved. , Can be selected, and the original correction can be made without affecting other same search word candidates. Therefore, it is possible to make an appropriate correction according to the request of each of the same search word candidates.

Also, in the present invention, when a function of displaying keyword data in comparison with the corresponding text is provided, it is possible to take into account how to use search word candidates in the text data text. Therefore, it is possible to accurately review and correct the search word candidate.

[0012]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is an explanatory diagram showing a schematic configuration and a processing flow of a keyword creation system according to an embodiment of the present invention. FIGS. 2 and 3 are flowcharts showing processing procedures by the system. .

The keyword creation system according to the present embodiment includes a keyword data creation device 6 that inputs a body text stored in a floppy disk FD1 and extracts and creates keyword data from the text by referring to a keyword dictionary. The created keyword data is input from the floppy disk FD2 in which the keyword data is stored, and the keyword data is reviewed and corrected to create a keyword, and the keyword is stored in the floppy disk FD3. Device 8. However, the storage medium used is not limited to a floppy disk.

In this embodiment, the creation of keyword data is performed according to the procedure shown in FIG.

That is, first, text data (text) corresponding to a text to be stored on a CD-ROM is stored in a floppy disk.
The data is input to the data creation device 6 by the disk FD1 (step 110), and from this text data, a noun of a search word candidate is extracted by referring to a previously created keyword dictionary (step 112). The reading is read from the keyword dictionary (step 114), and keyword data including the search word candidate and the reading is created (step 116). FIG. 4 conceptually shows the above processing. The created keyword data is stored on a floppy disk FD2, and is edited and edited in detail later.
Used for correction work.

As the keyword data creating device 6, for example, a workstation can be used.
As text data to be input, data processed for a CD-ROM, for example, data created in the MS-DOS format can be used.

In the keyword dictionary used for extracting nouns of search word candidates from text data, only words (nouns) that can be keywords are registered.
As shown conceptually in FIG. 5, the contents of the case are a matching key and keyword information. The keyword information includes (A) a candidate for a search word (keyword), (B) its reading,
(C) Dividing position of compound word, (D) Dividing unit noun (expanded form), and (E) Reading of expanded form. Note that the compound word means a noun in which a plurality of unit nouns are connected.

In the extraction of the search word candidates by the keyword dictionary, when there is a noun corresponding to the matching key in the text, the keyword (search word) candidate corresponding to the matching key and the keyword information are read from the keyword dictionary. It is performed by This keyword dictionary is prepared in advance by selecting nouns that can be keywords from data such as index words and headwords of dictionaries.

An example of the contents of the keyword dictionary is shown below. (Example) Matching key: Mediterranean trade Keyword information ・ Keyword: Mediterranean trade ・ Reading: Chika Kaibowe ・ Division position: Mediterranean ● Trade ・ Expansion type: Mediterranean, trade ・ Expansion type reading: Chichukai, Boweki

The keyword data created in step 116 described above is input to the reviewing / correcting device 8 of this embodiment, and processed according to the following procedure to create a keyword.

As the reviewing / correcting device 8, a display 12 is provided on a device body 10 as shown in FIG.
A pen computer is used which can input data on the display 12 with the pen 14 and can input and save data with the floppy disk 16. Various processing procedures including the processing shown in the flow chart of FIG. 3 described below are input to the pen computer, and function as a reviewing / correcting device.

First, in step 210, the above step 1 is performed.
16 and the search word candidates and their readings (kana)
Keyword data including the text of the text (text data) is input to the reviewing / correcting device 8 by the stored floppy disk 16 (corresponding to the FD 2 in FIG. 1), and then the search word candidates are compared with the text. In addition, when a plurality of identical search word candidates are included in the job, the new search word candidates appearing for the first time and the existing search word candidates appearing after the second time are distinguished and displayed on the display 12 so as to be clearly understood. (Step 212).

FIG. 7 schematically shows a correction screen displayed at step 212 when the user reviews and corrects the keyword data, and is displayed on the display 12 at the top of the figure. The displayed text, keywords, correction results, and menus are displayed separately for each display area.

In the text display area, text portions containing search word candidates to be reviewed and corrected are displayed.
In addition, the corresponding search word candidate is displayed with its lightness and darkness inverted so that it can be clearly distinguished from other character parts. In addition, since the text screen and the keyword screen do not correspond to one line unit, by selecting a search word candidate, a relevant part of the text including the search word candidate is displayed. Therefore, when a search word candidate to be described later is reviewed and corrected, the text can be referred to, so that the work can be performed accurately.

In the keyword display area of the display screen shown in FIG. 7, search word candidates consisting of characters represented by symbols such as ○ △ are displayed one by one from the top, and these search word candidates are displayed in the keyword dictionary. , And are displayed in order from the beginning of text data such as a sentence.

If there is a plurality of the same search word candidates in the keyword data, a new search word candidate appearing for the first time (FIG. Is displayed only as "new") and the second and subsequent search word candidates (only "new" is displayed in the figure)
Are displayed with one character shifted between them.

The compound word is shown in the keyword display area 3
At the same time as the dividing position is displayed as shown in the line, the derived word is expanded and displayed from the beginning, as shown in the fourth and fifth lines. The information on the division position and the derivative words is taken from the keyword dictionary when the keyword data is created.

Numerals, affixes, hiragana, transposed nouns, 1
In order to make it easy to understand words that need attention in reviewing, such as character keywords, they are highlighted.

In the correction result display area of FIG. 7, the result of correcting the search word candidate is displayed. In the menu display area, the type of processing mode that can be selected and executed on the current display screen and the current processing mode are displayed. The mode name to be selected when shifting from the screen to another mode screen is displayed.

FIG. 9 is a schematic diagram showing the editing and reviewing process shown in FIG.
It shows a specific example of a correction screen. However, the division position of the compound word is indicated by ●, and the menu display area is shown at the lower end of the screen.

After the keyword data (text and search word candidate group) is displayed in the step 212, it is reviewed on the correction mode screen shown in FIG. 7 as to whether or not each search word candidate is suitable as a search word. If the division position given to the compound word is not appropriate, it is corrected on the display 12 using the pen 14.

The reviewing / correcting device 8 of this embodiment has the following characteristic correcting functions.

In the case of the same search word candidate, when a new search word candidate appearing for the first time is corrected, all of the subsequent search word candidates are automatically displayed as nouns with the same correction. In addition, since the new search word candidates have been corrected, the existing search word candidates in the same correction state are selected and individually selected, that is, the other search word candidates are changed to the same search word candidates. It is possible to make original corrections without affecting it.In addition, when a new search word candidate is corrected, the correction made at the same time is canceled, and only the specified existing search word candidates are changed to the state before correction It is also possible to return to.

In the present embodiment, the review and correction work is performed as follows. First, when the search word candidates displayed in the keyword display area are new (step 214), the search word candidates are reviewed and corrected irrespective of whether or not there are other identical search word candidates. On the other hand, if it is determined in step 214 that the current search word candidate is not new from the state displayed separately on the screen and is already the same search word candidate that has already been corrected, it is usually at the stage of the new search word candidate. When the correction is finished, the review and correction are not performed. If the user wants to perform another correction on the existing search word candidate by itself, the review and correction are performed in step 216 as in the case of the new search word candidate.
Correction is performed (step 218). In addition, when modifying a search term candidate that has already been selected, if a new reference mode is selected in the menu display area, the screen can be switched to a screen where the same search term candidate appearing for the first time is displayed, and its contents can be confirmed. .

When the search word candidates are corrected in steps 214 to 218 described above, the result is displayed in the correction result display area. That is, FIG. 7 shows the result of correcting the search word candidate on the second line and adding one character to the search word candidate on the fifth line to make it four characters. However, the correction result of the same search word candidate is not displayed except for the first appearance of the search word candidate, and is displayed only in the case where the search word candidate has already been corrected.

An example of the correction executed here and a method thereof will be described below. The following corrections (1) to (4) and (7) can be executed in both the keyword display area and the text display area.

(1) All delete mode Select the all delete mode in the menu, and touch the search word candidate to be deleted once with a pen. Although not shown, FIG.
The deletion modes in the menu display area include full deletion and partial deletion.

(2) Partial deletion Select the partial deletion mode in the menu, touch one character twice with a pen to delete one character, and touch the first character and the last character with a pen to delete consecutive characters. Touch each time.

(3) Addition After selecting the addition mode of the menu and once touching the first character or the last character of the search word candidate corresponding to the position to be added,
Input the character (string) to be added with a pen.

(4) New Addition Select the new addition mode from the menu, and touch the first character and the last character of the character string desired to be a keyword existing in the body once in the body display area, or A keyword is added by inputting with a pen in the display area.

(5) Correction of compound word division position Select compound word division mode from the menu, and touch a character in a search word once with a pen to immediately enter a division mark (/).
Is inserted, and the division mark already displayed is deleted by touching once.

(6) Determination of compound word second division position When one compound word has a plurality of division methods, for example, the compound word is “physicist”, the first division position is “physics / scholar”, and When the second division position is “physics / person”, the first division position is determined by the method (5), and then the compound word second division mode in the menu is selected. Next, the compound word to which the first division position determined in the above (5) is attached can be copied by touching once with a pen, and the same operation as in the above (5) can be performed on the copied compound word. To determine the second division position.

(7) Division into different keywords Search word candidates that should be originally divided into two (excluding compound words)
Is displayed in a concatenated manner, selecting the division mode in the menu, and touching a character in the search word candidate once will result in two keywords being divided immediately before that.

When correcting and determining the division position of a compound word at the time of the above review and correction, in order to match the division position,
To perform the check, select the division matching check mode (not shown) in the menu, display a compound word division position matching check list (division pattern) as shown in FIG. It is possible to match the division position with another identical compound word while referring to it. In the division position matching check list, only compound words having a plurality of division methods are displayed as division patterns with different division positions. From the screen shown in FIG. 10, when "Return" in the menu is selected, the screen can be returned to the review / correction screen shown in FIG.

When the correction processing of steps 214 to 218 described above is completed for all the jobs of this job (step 220), it is determined as a keyword (step 222).

In the above step 222, the editing and reviewing of FIG.
Correct the search term candidates displayed on the correction screen appropriately,
After determining the keyword as a keyword, when the user selects the kana correction mode in the menu, the screen can shift to a kana correction screen shown in FIG. The “expansion” shown below the compound word (corresponding to keyword 3) displayed in the keyword display area in FIG. 11 expands and displays this compound word for each of its constituent words (unit noun). It means that there is.

On the kana correction screen shown in FIG. 11, kana is reviewed and corrected as described below (step 224).

The display screen shown in FIG. 11 is provided with display areas for text, keywords, kana, and menus.
All keywords determined in the process of 222 are displayed in a list in comparison with the text, and readings of the determined keywords (including compound words and expanded forms thereof) are displayed in the kana display area. This kana is taken from the keyword dictionary when creating the keyword data,
When a keyword is determined, it is automatically assigned to the keyword and displayed.

An example of kana correction executed here and a method thereof will be described. This kana correction can be performed in either the keyword display area or the kana display area because some of the keywords themselves are written in kana.

The kana correction includes all deletion, partial deletion, and addition as in the case of the above-described search word candidate correction. This correction can be performed by substantially the same operation as in the case of the search word candidate. The kana correction includes a new addition mode and a copy mode in addition to the correction modes.

The new addition is a correction to be made when there is a plurality of readings for the same keyword. The new addition mode of the menu is selected, and as shown in the display screen of FIG. Then, another reading is added by inputting another reading with a pen in the kana display area.

Copying is a correction to be made when the keyword itself is written in kana. When the user selects the copy mode in the menu and touches the keyword once with a pen, the keyword is copied as it is to the kana display area. Input as a reading.

When the correction of the kana is completed by the review and correction processing in step 224 described above, the kana is determined (step 226), and the determined keyword and the kana are stored on, for example, a floppy disk to create a keyword. Is completed (step 228).

From the kana review / correction screen of FIG. 11, the screen can be shifted to the search word candidate review / correction screen of FIG.

According to the present embodiment described in detail above, the CD-R
When creating a keyword to be stored in the OM, even if multiple identical search word candidates exist in the text data,
The new search term candidates appearing for the first time and the existing search term candidates appearing after the second time can be clearly distinguished and displayed. If the new search term candidates are reviewed and corrected, the existing search word candidates can be displayed at the same time. The same corrections have been made, and the original search word candidates can be modified independently without affecting other same search word candidates, so it is possible to perform appropriate review and correction of the search word candidates , It is possible to efficiently perform the keyword creation work.

Further, according to the present embodiment, the search word candidates can be corrected while comparing the text, so that the review and correction work can be performed accurately.

Further, according to the present embodiment, after the keyword is determined, the reading (kana) is determined only for the determined keyword, so that the keyword creation operation can be performed efficiently in this aspect as well. Become.

Although the present invention has been specifically described above, the present invention is not limited to the above-described embodiment, and can be variously modified without departing from the gist thereof.

For example, in the above-described embodiment, the case where the pen computer is used as the reviewing / correcting device has been described. However, the present invention is not limited to this, and another computer may be used or a dedicated machine may be used.

[0061]

As described above, according to the present invention,
When creating a CD-ROM keyword, even when a plurality of identical search word candidates exist, it is possible to clearly distinguish between the first occurrence and the second and subsequent occurrences on the display. Since it is possible to easily and accurately review and correct the same search word candidate and to efficiently create keywords,
It is possible to reduce the load of the keyword creation work.
