Abstract

PURPOSE:To permit a user to directly refer to/link arbitrary two electrons information by simultaneously displaying a reference body and a referred body and dragging a referred body picture to reference body data. CONSTITUTION:When an arbitrary character string which is to be referred to is designated by using a mouse and the like in reference body data inputted by a reference body data input part 1, a reference character string registration part 3 registers it as a reference character string and a reference area detection part 5 detects a reference area where the reference character string is positioned on reference body data. A referred body picture shift position detection part 6 detects to which part on a screen the referred body picture is shifted when the user shifts it. A reference link discrimination part 8 sequentially compares it with the reference area of the registered character string, and discriminates to which reference area of the reference body it is positioned. A reference link generation part 9 links the reference character string corresponding to the reference area with the referred body so as to generate a reference link.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a computer information system such as a hypertext having a non-sequential structure for easily and efficiently creating a reference link between reference object data and referenced object data. Regarding the link creating device.

[0002]

2. Description of the Related Art In recent years, computer systems have come to handle not only text data consisting of character data but also various data such as image data, audio data, video data, etc.
It has begun to process sequential data.

The term hypertext refers to information having a non-sequential structure and was conceived in the mid-1960s. As shown in FIG. 9, in the hypertext electronic information system, information is linked (linked) with other information.
In addition to being able to do so, it is possible to create paths between related information that can be referred to each other. As described above, it is referred to as a reference link that the reference object data to be referred to and the referenced object data to be referred to are combined to create the link path and can be referred to each other.

FIG. 10 shows a conceptual diagram of a reference link. The arrow in the figure represents one reference link, and reference links having various flows are set according to the need of the user who requests information. By using the reference link as shown in FIG. 10, unlike the case where the information is spelled in a sequential structure in a paper medium such as a book and the case where the user reads the introduction from the beginning to the final one-sidedly, the hypertext electronic information is read by the user. Created with a non-sequential structure in the system,
Editing, organization, expression and reference can be achieved freely. Also, not only character data but also image data
It can handle various data such as audio data and video data.

As a conventional electronic information link creating device, software ToolBook (Using T
oolBook --- A Guide to Building and Working with Boo
ks, Asymetrix Corporation, 1989). 11,
12A to 12F are explanatory views when a reference link between information is created by this ToolBook. ToolB
ook indirectly creates a reference link as follows by operating the interactive windows shown in FIGS. 11 and 12.

FIG. 11A shows text data of a reference body. First, the document to be referred to is displayed in one window on the screen according to the user's designation. When the character string to be referred to is specified, the character string is highlighted on the screen (Salary in Fig. 11 (a)).
Levels). After the reference character string is specified, from the command menu of FIG. 11 (b), select "Ob
When the command "Hotword Properties ..." is selected from the "ject" command, an interactive window as shown in FIG. 11 (c) appears, the instruction for the reference character is displayed, and the user waits for input.

When the "Link To" button is pressed here, the above interactive window is closed and the "Link To" button shown in FIG.
"Link To" conversational window will be displayed.
The user must follow the instructions in the "Link To" interactive window to locate the referenced document in order to link. That is, the user opens the referenced document as the link destination by a normal operation of opening the document in the same window, and searches for the data of the referenced object as shown in FIG.

In order to link the referent data, "Li
nk To "Conversation window" When the "OK" button is pressed, the "Link To" conversation window is closed and Tool
The interactive window of Book automatically returns to the original reference document and displays it as shown in FIG. 12 (f). At this time, the reference object document data of FIG. 11A and the referenced object data of FIG. 12E are linked (linked).

As described above, the operation of linking information is
It can be divided into two main operations: reference object data specification and reference object document data search. To specify the reference object data after specifying the reference object data, switch the display of the reference object document with the reference link processing operation continued in the "Link To" conversational window to display the reference object data. I have to search.

[0010]

However, according to the above-mentioned conventional example, the reference links are designated one by one in accordance with a series of processing procedures of designating a designated character string in the reference body data and designating a designated link in the referenced body data. Since it is created, only one reference link can be created in one step, and it is inefficient to set many reference links.

Further, when the referent data is designated, it is necessary to switch the reference object document in the window display to the document of the referent object, so that the user needs to refer to the reference object data / reference object data. There was a problem that you had to clearly recognize the position on the document. This is because if the user does not clearly recognize the storage location of the referent in the document, it takes a lot of trouble to search for the referent data on the screen, and during that time, This is because the contents of the reference data may be forgotten.
This becomes a serious problem as the document becomes huge.

In view of the above problems, it is an object of the present invention to provide an electronic information link creating apparatus that can easily and efficiently create a reference link between reference object data and referenced object data.

[0013]

In order to solve the above problems, the present invention creates a reference link between the reference data to be referred to and the referenced data referred to for the reference data. An electronic information link creating device, a display means for displaying reference object data and referenced object data, a reference character string registration means for storing one or more designated reference character strings in the reference object data, and each reference. Reference area detection means for detecting an area of the character string on the screen and reference object data including one or more reference character strings are displayed, and the reference object data candidates are successively displayed on the display means by a user operation. Operation means for displaying and determining the referenced object data to be linked, referenced object image display control means for displaying a graphic indicating the type of the referenced object data on the display means together with the reference object data, and on the screen Referenced object image moving means for moving the figure, reference link determination means for determining whether or not the figure after the movement is within one of the areas of the reference character string on the screen, and reference When the link determining means determines that the reference area is within the range of the reference area, a reference link creating means for storing the reference character string indicated by the reference area and the information for identifying the referenced data represented by the graphic, An electronic information link creating device characterized by having

[0014]

According to the present invention, when the user specifies a character string to be referred to from the reference object data by using the input means by using the mouse or the keyboard, the reference character string registration means stores the reference character string. Remember one or more. For each reference character string, the reference area detecting means detects the reference area located in the reference body data. The operation means displays the reference object data including one or more reference character strings, and causes the display means to sequentially display the reference object data candidates by the operation of the user to determine the reference object data to be linked. To do. When the reference object data is determined, the reference object image display control means displays a reduced figure indicating the type of the reference object data on the display means part together with the reference object data.
When the referenced object image moving means moves this figure,
The reference link determination unit determines whether or not the graphic is located within the range of any of the reference areas of the reference object data. If the coordinates of the figure are located within the range of the coordinates of the reference object data, the reference link creating means stores the reference character string of the reference area and information for identifying the referenced object data indicated by the figure. By setting the reference link.

First, the correspondence with claims will be described, and then each configuration in FIG. 1 will be described. Although not shown, the display means refers to a CRT display device or the like. The reference character string registration means comprises the reference character string registration unit 3 and uses the reference character string / reference area storage register 71 of the buffer memory 7.

The reference area detecting means comprises a reference area detecting section 5 and uses a reference character string / reference area storing register 71 of the buffer memory 7. The operation means includes a reference object data input unit 1 and a referenced object data input unit 2. The referent image display control means includes the referent image display unit 4 and a register 7 for storing the referent in the buffer memory 7.
2, 73 are used.

The referenced object image moving means has a function of moving an image on the display means, includes a referenced object image moving position detection section 6, and includes registers 72 and 73 for storing the referenced object in the buffer memory 7. To use. The reference link determination means is
Of the buffer memory 7, registers 72 to 77 for storing reference objects and referenced objects are used.

The reference link creating means comprises a reference link creating section 9 and uses a reference character string / reference area storage register 71 of the buffer memory 7. In FIG. 1, a reference object data input unit 1 takes in an instruction from a keyboard / mouse by a user or reference object data input from a disk file or the like. The reference character string registration unit 3 uses the designated arbitrary character string from the reference object data input from the reference object data input unit 1 as a reference character string, and stores the reference character string / reference area storage buffer in the buffer memory 7. Register at 71. The registered reference character strings are collected into one, and the reference character string / reference area storage buffer 7 is provided as a reference character string list.
Stored in 1. Table 1 shows the data structure of the node of each reference character string in this reference character string list.

[0019]

[Table 1]

The length of each field here is in bytes. The "start character position" and "end character position" fields represent the start character position and end character position of one reference character string in bytes from the origin with respect to the origin of the reference object data displayed in the window. The relative position data is shown. These two values are used to acquire the content of the reference character string and the coordinates of the start character and the end character in the reference body data.

The field of "referenced object identifier" has an initial value of zero before link setting, and shows an identifier of referenced object data after link setting. This identifier is used for searching the referenced data when the referenced data is desired to be viewed from the reference character string. The field of "reference area node pointer" indicates the pointer of the node of the reference area of the reference character string. With this reference area node pointer, the reference area corresponding to each reference character string can be taken out.

The "next reference character string node pointer" field indicates the pointer of the node of the next reference character string in the reference character string list. If this node is the last node in the reference character string list, set this field to zero. Further, even if two or more reference character strings overlap, the relationship between the upper and lower layers of each reference character string can be represented by the order before and after the nodes of the reference character string list.

The reference area detection unit 5 determines the reference character based on the data in the "start character position" and "end character position" fields of the reference character string list registered in the reference character string / reference area storage buffer 71. Find the reference area represented by the upper left coordinate of the start character and the lower right coordinate of the end character of the column. This reference area is represented by one rectangle when the reference character string is located in one line, as shown in FIG.
When the reference character string exceeds one line, it is represented by a set of some rectangles. ... The detected reference areas are collected by the reference area node and stored in the reference character string / reference area storage buffer 71 of the buffer memory 7 as one reference area list. --- Table 2 shows the data structure of each reference area node in the reference area list.

[0024]

[Table 2]

The length of each field here is in bytes. "Reference area coordinates (R_left, R_top, R_
"right, R_bottom)" field stores the reference area represented by upper left coordinates and lower right coordinates. "Reference character string node pointer" stores the pointer of the node of the reference character string corresponding to the reference area. This reference character string node pointer is used to retrieve the reference character string corresponding to the reference area.

The field "next reference area node pointer" stores the pointer of the reference area node next to the reference area node in the reference area list. if,
This reference area node is set to zero if it is the last node in the reference area list. In addition, the relationship of the upper and lower layers of each reference area can be expressed by the order before and after the nodes in the reference area list.

When the above-mentioned reference character string node and reference area node are viewed from the data structure, the reference character string list and the corresponding reference area list have a structural relationship as shown in FIG. Each reference character string is stored in one reference character string node, and the reference area corresponding to the reference character string is stored in one or more reference area nodes. The referent data input unit 2 allows the user to input a keyboard, a disk file,
Alternatively, the referenced data from another peripheral device (for example, a static image from a scanner or a continuous image captured by a camera) is input.

The referenced object image display unit 4 displays a specific image or graphic (hereinafter referred to as a referenced object image) representing the type of the read referenced data on the display unit together with the referenced object data. This referent image is, for example, a text data image displayed in a small size outside the window of FIG. 5B, a video data image of FIG. 6B, and a voice synthesis data image of FIG. 7B. Is displayed. This allows the user to know at a glance the type of referenced data.

When the user moves the reference object image on the screen via the input unit, the reference object image moving position detecting section 6 returns to the original position (Px ', Py') of the center point of the image. , And the horizontal and vertical movement distances (dx, dy) detect the coordinates (Px, Py) in the screen coordinate system of the center point of the image after movement.
This (Px, Py) is obtained by the following equation. Px = Px ′ + dx Py = Py ′ + dy The detected coordinates (Px, Py) of the center point are stored in the Px register and the Py register of the buffer memory 7.

The buffer memory 7 includes a reference character string / reference area storage buffer 71, a Px register 72, and a Py register 7.
3, R_left register 74, R_top register 75, R
It is composed of a _right register 76 and an R_bottom register 77. Reference character string / reference area storage buffer 71
Stores the reference character string stored by the reference character string registration unit, and stores data relating to the reference area corresponding to each reference character string.

The Px register 72 and the Py register 73 store the coordinates (Px, Py) of the center point detected by the reference object image moving position detecting section 6. R_left register 74, R_top
The register 75, the R_right register 76, and the R_bottom register 77 respectively store the upper left coordinates and the lower right coordinates of the rectangular area of the reference area. The values stored in these six registers are whether the center point of the referenced image (registers 72 and 73) is located inside any of the reference areas (registers 73 to 77) of the reference character string list. That is, it is used to determine which reference character string the referenced image overlaps on the screen.

The reference link discriminating section 8 first discriminates whether or not the reference object image is located on the reference object. That is, it is determined whether or not the central coordinates of the referenced object are within the range of the reference object window. If it is located in a certain reference object, the reference link determination unit 8 determines the center point position (Px_scree) of the image stored in the PX register 72 and the PY register 73.
n, Py_screen) from the screen coordinate system to the reference body coordinate system (Px_ref, Py_re) in the window display by the following formula.
f)).

Px_ref = Px_screen-Px_screen
_Ref + dx_scroll Py_ref = Py_screen − Py_screen_ref +
dy_scroll Here, (Px_ref, Py_ref) is a coordinate value in the reference body coordinate system of the center point position of the reference object image. (Px_sc
reen, Py_screen) are coordinate values in the screen coordinate system of the center point position of the reference object image. (Px_screen_ref,
Py_screen_ref) is a coordinate value in which the origin of the reference body coordinate system is relative to the screen coordinate system. (Dx_scroll, dy_
scroll) is the offset of the reference object in the horizontal and vertical directions in the reference object coordinate system. However, the reference body coordinate system (coordinates on the window) and the screen coordinate system both have the upper left coordinate as the origin, and the horizontal direction increases to the right and the vertical direction increases to the lower side. The converted coordinates are again PX register 7
2, stored in the PY register 73.

The reference link determination unit 8 then coordinates the center point of the referenced image in the Px register 72 and Py register 73 after coordinate conversion, and the R_left register 74, R_top register 75, R_right register 76, and R_bottom register. 7
The upper left coordinates and the lower right coordinates of the stored reference areas of No. 7 are compared, and the center point coordinates of the reference object image are calculated by the following (Expression 5) and (Expression 6). Determine if it is located at.

R_left ≤ Px <R_right R_top ≤ Py <R_bottom The above coordinate conversion / comparison / discrimination processing of the reference link discrimination unit 8 is registered in the reference area list stored in the reference character string / reference area buffer 71. This is sequentially performed for each of the reference areas that are displayed. If it is read and converted to the reference body coordinate system and positioned, the reference character string corresponding to the reference area and the reference object data for displaying the reference object image in the reference object image are created.

When the reference link discriminating unit 8 discriminates that the center point of the image of the referent object is located within the range of the reference region, the reference link discriminating unit 9 puts it between the reference object and the referent. Create a reference link. That is, the identifier of the referenced object data is written in the referenced object identifier field of the reference character string node. With respect to the electronic information link creating apparatus configured as described above, an operation of creating a reference link will be described with reference to the process flow charts of FIGS.

(1) First, the input means is
Whether to select the reference object data input mode or the reference object input mode is input (S5 in FIG. 2). When the reference object data input mode is selected, the reference object data input unit 1 waits for input of reference object data (S'10). When the referent data input mode is selected, the referent data input unit 2 waits for input of the referent data (S1).
0). If no data is input, the process can end (S15).

(2) When the reference object data input mode is selected and the reference object data is designated from the reference object data input section 1 (S'10), the reference object data is displayed on the screen of the display means. To be done. Read. Further, when the character string to be referred to in the reference object data is specified by the reference object data input unit 1 (S'20), the reference character string registration unit 3 causes the reference character string / reference area storage buffer 71 to The start character position and the end character position (see Table 1) are registered (S'30). Next, the reference area detection unit 5 detects all the reference areas corresponding to each reference character string in the registered reference character strings, and one reference area list (Table 2, FIG. 4).
Reference character string / reference area storage buffer 71
(S'40). When the user further registers another reference character string or inputs another reference character data in the reference object data, the reference character string registration and The reference area detection operation is repeatedly performed (S'50, S'6.
0).

(3) When the above reference character string registration and reference area detection operations are completed, the reference link determination section determines whether or not the contents of the registers 72 and 73 of the buffer register are 0 "zero". Thus, it is determined whether the referent data has been specified by the user (S'70). If it has been specified, the process proceeds to S40, and if it has not been specified, S
Return to 5. If the referent is not designated, the user must select the referent data input mode (S5) and input the referent data of the link destination by the referent data input unit 2 (S10). ). When the referenced data is set, the referenced object image display unit 4 displays on the display means an image (referenced object image) obtained by reducing the referenced object data together with the reference object data (S20). Further, when the user wants to specify the referenced data, the above S10, S2
By repeating 0, other referent data can be input (S30).

(4) The reference object image moving position detecting section 6
First, when the referent image is displayed (S40), the coordinate position of the center point on the screen is extracted and the buffer memory 7
Stored in the Px register 72 and Py register 73 of
50) Next, it is determined whether the reference object data is registered in the reference character string / reference area storage buffer 71 and is present on the screen (S60). If the reference object data does not exist, the process returns to S5 and waits for data input. At this time, the user needs to perform the operation of inputting the reference object and designating the reference character string to be referred.

When the reference object data exists, the reference object image moving position detecting section 6 determines the center point (Px, Py) of the reference object image.
Is positioned within the window display range of any reference object data (S70). If it is not located within any of the reference object data, the operations from S40 to S70 described above are repeated until it is detected that the center point of the reference object image is located at some reference object.

When it is detected that the center point of the referenced object image is located on a certain reference object, the reference link determination unit 8 first determines the center point (Px, Py) of the referenced object image from the screen coordinate system. S
Converted to the coordinate system of the reference object data detected by 70,
The coordinates of the converted center point are stored in the Px register 72 and the Py register 73. Next, the reference link determination unit 8 extracts the reference area list of the reference object stored in the reference character string / reference area storage buffer 71, and determines in which reference area the center point of the reference object image is located. It is detected as follows (S90 to S120). Reference link determination unit 8
On the basis of the extracted reference area list, sequentially extracts the pointers of the respective reference area nodes (S90), determines whether or not the pointers of the extracted reference area nodes are null (S100), and returns null. If it is (null), it means that the search has been performed up to the end of the reference area list. Therefore, the process exits the loop, and the process returns to S40 to continuously detect whether or not it is the referenced object image dragged by the user.
When the pointer of the extracted reference area node is not null, the reference link determination unit 8 determines the upper left coordinates (R_left, R_top) and the lower right coordinates (R_right, R) of one reference area.
_Bottom) is stored in registers 74 to 77, respectively (S
110), the center point (Px, Py) is the reference area (R_lef)
If it is determined that the character string is located at t, R_top, R_right, R_bottom) (S120), the reference character string pointer of the reference area node is used to extract the reference character string corresponding to the reference area (S130), and it is extracted. A reference link is set between the referenced character string and the referenced object that is displayed in the referenced object image, that is, the referenced object identifier (see Table 1) of the reference character string list is set (S140).

When the center point (Px, Py) is not located in the reference area (S120), the process returns to S90, and the reference link determination unit 8 extracts the next reference area node pointer from the reference area list, The processing from S90 to S120 is repeated until the reference area where the center point is located is found. After setting the reference link in S140, it is determined in S15 whether or not the reference link operation is ended.

The reference link is set by the above operation. For better explanation, the operation of the reference link of the electronic information link creating apparatus of this embodiment viewed from the user side will be described using the same example as the conventional example. First, the user selects the reference object input mode (S5) and then specifies the reference object data (S'10). At this time, reference body data “Buissiness Management of J” as shown in the upper side of FIG.
The apan "(hereinafter referred to as reference D ') is displayed in the document window (hereinafter referred to as window W').

Next, the user specifies the character string "Salary Levels" (the highlighted portion) to be referred to for the reference body D '. This reference character string is registered in the reference character string / reference area storage buffer 71 by the reference character string registration unit 3 (S'20, S'30), and the reference area corresponding to the reference character string by the reference area detection unit. Is detected,
The corresponding reference areas are stored in the reference character string / reference area storage buffer 71 as one reference area list L '(S'40). At this time, in the reference area of FIG. 5A, since all the reference character strings are located in the same line, one rectangle (42, 125, 149, 144) is displayed. FIG. 6A shows a display screen when registering the reference character string "Jishu Kanri Activities" in the same reference object data as in FIG. 5A, and FIG. Labor-Man
Shows the display screen when registering "agement Relations".
These are registered in the reference character string / reference area storage buffer 71. The reference character string can be registered in this way by registering a plurality of character strings.

After that, when another reference character string or another reference object is not input (S'50, S'60), the user selects the reference object input mode (S5), and FIG. The referent data “Salary Levels” (hereinafter referred to as the referent D) such as the lower side is designated (S10), and the document window (hereinafter referred to as the window W) is displayed. At this time, the reference object window W ′ and the referenced object window W are simultaneously displayed, and the user can clearly see the contents of the reference object D ′ and the referenced object D on the screen. This state is shown in FIG.

In order to link the two documents, the user shrinks the referenced object window W by the referenced object image display section (S20), and the reference character to which the reduced referenced object image is to be linked. Stack in rows. That is, when the user presses the reduction button on the upper right side of the window W in FIG. 5A, the reduced image of the reference object D is obtained as shown in FIG. 5B. Next, as shown in FIG. 5C, the user uses a mouse or the like to superimpose it on the reference character string "Salary Levels" to which the reference target image is to be referred.

As a result, when the referenced object image moving position detecting section 6 detects that the referenced object image of the referenced object D has moved (S40), the coordinates of the center point of the moved referenced object image ( 237, 381) is detected (S50), and if the reference object image exists (S60), it is determined whether the reference object image is located in the reference object window W '(S7).
0). When it is determined that the reference object image is located in the reference object window W ′ as shown in FIG. 5C, the reference object image movement position detection unit 6 causes the center point of the reference object image to move in the screen coordinate system. After converting (237, 381) to (96, 136) in the reference object window W'coordinate system, the reference area list L'of the reference object D'stored in the reference character string / reference area storage buffer 71 is stored. Each reference area is compared in turn with the transformed coordinates. In the case of FIG. 5C, it is detected that the center point of the reference object image is located in the reference area (42, 125, 149, 144) (S90 to S120), so the reference corresponding to the reference area is detected. The character string "Salary Levels" is taken out (S130), and the reference character string "Sala
"ry Levels" and the referenced object D are connected to create a reference link, that is, the referenced object identifier (see Table 1) of the reference character string list is set (S140).

Furthermore, when creating another reference link, the user returns to the referent data input mode and specifies the referent data (S10), and sets the referent window and the referent window. After displaying (FIG. 6 (a) or FIG. 7 (a)), the referent image which is the reduced image is displayed (FIG. 6 (b) or FIG. 7 (b)), and the same operation as above is performed. . As described above, once a plurality of reference object data are registered, a plurality of reference links can be created by sequentially specifying the referenced object data.

Here, the referenced data on the lower side of FIG. 6A shows a continuous image. The video data of continuous images is specified by filling in the definition field list (AV Processing Unit) shown in this window. The data of the definition field shown in the figure is the size of a quarter of the video data from the 4069th screen to the 4096th screen, and the relative position (40, 10) to the reference character string to be linked. It is specified to display. Then, when the reference character string is clicked after the completion of the reference link, the referenced video data defined above is reproduced. In addition, the referenced data on the lower side of FIG. 6A indicates voice synthesis data. Then, when the reference character string is clicked after the completion of the reference link, the content of the referred-to-subject voice synthesis data is reproduced by the voice synthesizer.

As described above, the reference object data is not limited to text data, and for example, reference links can be created even for multimedia data in which graphics, moving images, images, voices, synthetic voices, and the like are mixed. . Further, although the reference area in this embodiment is extracted as a reference character string from the reference object data, the present invention can make any area of the reference object a reference area. For example, an illustration in one document can be used. If a predetermined area in one illustration, one table of one document, or a field with one table is registered as a reference area, all reference links can be made.

[0052]

As described above, according to the electronic information link creating apparatus of the present invention, once the reference character string is registered, it is sufficient to specify the referenced data one after another. Has the effect of setting multiple reference links. In addition, when the reference object data is specified, the reference object document in the window display is also displayed at the same time, so the user can clearly recognize the position of the reference object data / reference object data on the document. The effect is that it does not have to be. This has a larger effect as the document is larger and the number of reference links to be set is larger.

Moreover, the user directly
Create a reference link by overlaying with reference data
This has the effect of simplifying the operation.
