Abstract

PURPOSE:To simplify link setting and to efficiently use memory by forming a pair of each information file and a key word with respect to the file, and storing the pair in a key word table. CONSTITUTION:The contents of an arbitrary information file is displayed on one window of a CRT 9 via a window system 8, and a phrase that becomes a key to another information in the contents of a displayed information file is designated. When the key word whose designated phrase coincides with that of the key word 21 stored in a key word table 22 exists, the information file in accordance with the key word 21 i.e. the content of a linked information file is displayed on the CRT 9 by opening the same window or a new window. In such a way, the presence location information 20 of the information file and the key word 21 are registered on the key word table 22. Thereby, prescribed link setting work can be simplified, and the memory can be efficiently used.

Description

[Detailed Description of the Invention] [Objective of the Invention] (Industrial Application Field) The present invention relates to hypertext links, and in particular, the invention relates to hypertext links, and in particular, a method for registering specific character strings (keywords) related to each information file. This invention relates to a hypertext system that allows you to immediately refer to an information file corresponding to a keyword by specifying a keyword in the information file being referenced.

(Prior Art) Hypertext connects related information files in a network by embedding "link information" pointing to other information files in one information file. To set a link, if there is a related information file, for example, if a description of a certain word in information file A is written in information file B, then that word in information file A is the link source, A link is set with information file B as the link destination. In this case, multiple link sources can be set in one information file, but only one link destination can be set for one link source. The concept is shown in Figure 3.

In FIG. 3, information file A has link information 1 pointing to information file B, information file B has link information 2 pointing to information file A and link information 3 pointing to information file C, and information file C has link information 1 pointing to information file A. It has link information 4 that points to it and link information 5 that points to the information file D, and these link information directly points to other information files, but may also indirectly point to the linked information file. .

The link information mainly stores link source, link destination information, and link type. In other words, the link source information is information that indicates a specific character string or field in the information file where the link source exists, and the link destination information is the location where the link destination information file exists or the location where the link destination exists. This information indicates the location of the information file.

Also, the link type means that if the link source is specified,
This information indicates whether to display the contents of the linked information file in the same window in which the link source is displayed on the display device, or in a separate new window.

By constructing hypertext in this way, the user can specify a specific character string set as the link source by some method (for example, with the mouse) while viewing a certain information file, and then click the link destination information file. can be easily referenced.

Next, a general text system implemented on a computer will be explained with reference to FIGS. 4 and 5. FIG. 4 shows the configuration of a general hypertext system, with information A1 information B1 information C1...
The information consisting of the above information is stored as a file in the computer memory 6 or external storage device 7 with link information embedded as appropriate, and is displayed as a display device via the window system 8 of the window processing program stored in the memory 6. Displayed on CRTQ. CRT9
You can open multiple windows on the top, but usually the - windows contain only one piece of information (file content).
is displayed.

The user operates this system by using the keyboard 10 and mouse 11 to set link information, specify a link source, and the like.

FIG. 5 shows an example of information reference in the hypertext system. In the figure, a table of contents is displayed in window W1 on the CRT 9, but there is a "Foreword" link set with the mouse 11. When a character is specified, a new window v2 is opened in the direction of the arrow X, and the contents of the file containing the "preface" text are displayed in this window v2. Furthermore, if you use the mouse 11 to specify the word "Hypertext" to which the link for window v2 is set, window v3 will move in the direction of arrow Y.
will be opened in the same way, displaying the contents of the file with a ``hypertext'' description. In the figure, arrows X1Y are shown for convenience to explain the order in which windows w2 and W3 are opened, and are not actually displayed on the CRT 9.

In this way, when referring to information, if there are characters or fields for which a link is set in the information displayed in the window on the CRTe, by specifying it with the mouse 11 etc., the linked information can be accessed. (File contents)
is displayed in that window or in a newly opened window.

(Problems to be Solved by the Invention) However, in the conventional hypertext system described above, there are the following problems when setting the link.

(1) From a certain word (keyword A) to certain information (information A)
), if keyword A exists in multiple locations, it is necessary to set a link to information A for each location.

(2) Since link information (information such as link source, link destination, link type, etc.) is required for each link, the size of the information file becomes large.

The present invention has been made in view of the above circumstances, and is a hyperlink that simplifies link settings and allows efficient use of memory by storing each information file and its related keywords in pairs in a keyword table. The purpose is to provide a text system.

[Configuration of the Invention (Means and Effects for Solving the Problems) In order to achieve the above object, the present invention provides information indicating the location of information files and information on the information in a hypertext system that links information. A keyword table that stores keywords related to files in pairs; a display means that displays the contents of the information file; and a keyword that provides clues to other information files from the contents of the information file displayed on the display means. a specifying means for specifying, and a window processing means for displaying the content of the information file corresponding to the keyword on the display means when the keyword specified by the specifying means matches the keyword stored in the keyword table. With this configuration, links are set by registering related keywords when creating an information file, thereby simplifying the link setting work and making it possible to use memory efficiently.

(Example) Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a hypertext system according to an embodiment of the present invention, and FIG. 2 is a diagram showing a keyword table applied to the embodiment of the present invention.

Note that the same parts as in FIG. 4 are given the same reference numerals, and detailed explanation thereof will be omitted.

In FIG. 1, information consisting of information A1 information B1 information C1, etc. is stored as a file in a memory 6 in the computer or an external storage device 7, and a window which is a program that performs window processing stored in the memory 6 It is displayed on the CRTS as a display device via the system 8. Although a plurality of windows can be opened on the CRT 9, one piece of information (the contents of a file) is normally displayed in the second window.

In addition, as shown in FIG. 2, the memory 6 also stores location information 20 indicating the location of the information file and a keyword (not just one but multiple keywords) consisting of a specific character string related to the information file. A keyword table 22 in which keywords 21 (which may be used as keywords) 21 is stored.

This keyword table 22, as shown in FIG.
Created for each information file. That is, when each information file is created, links are set by registering keywords 21 related to that information file.
The information file is stored in the keyword table 22 together with the location information 20 of the information file. The keyword 21 can be changed later. One keyword table 22 exists in one hypertext system.

The user operates this system by using the keyboard 10 and mouse 11 to set links by registering keywords, specify link sources, and the like.

Next, the operation of one embodiment of the present invention having the above configuration will be explained.

The user causes the CRT 9 to display the contents of an arbitrary information file in one window via the window system 8. By specifying a word or phrase that is a link source, that is, a clue to other information, in the contents of the information file displayed on the CRT 9 with the mouse 11, a keyword 21 in which the specified word or phrase is stored in the keyword table 22 is displayed. If there is a match, the content of the information file corresponding to that keyword 21, that is, the linked information file, is sent to the window system 8 of the window processing program.
, the same window or a new window is opened and displayed on the CRT 9. At this time, if the keyword 21 that matches the specified phrase is registered in multiple information files, a list of those information files is displayed on the CRT.
9, and the user selects one from among them using the keyboard 10 or the mouse 11.

Further, if there is no keyword 21 that matches the specified word/phrase, no new information will be displayed because there is no linked information file.

By registering information file location information 20 and keywords 21 in the keyword table 22 in this manner, the registered keyword 21 can be specified with the mouse 11 and the corresponding information file can be created, similar to conventional hypertext systems. You can refer to the contents.

In the above embodiment, the keyword table was provided independently from the information file for each hypertext system, but the same function can be achieved by adding information on keywords related to that information file to each information file itself. can. In this case, it is sufficient to search for keyword information that has been added to all information files in the system.

Furthermore, in the above embodiment, when there are multiple information files that can be referenced from the same keyword, a list of those information files is displayed, but by adding priority information to the keyword table, The reference information files may be displayed in descending order of priority.

Furthermore, it goes without saying that the present invention is not limited to the above embodiments, and can be modified in various ways without departing from the gist of the present invention.

[Effects of the Invention] As detailed above, according to the hypertext system of the present invention, by registering information indicating the location of an information file and keywords related to the information file in the keyword table, You can refer to the contents of the information file corresponding to the keyword that matches the specified phrase.

Furthermore, since links are set by registering keywords in the keyword table, link settings can be simplified.
