Description

Description: TECHNICAL FIELD The present invention relates to an associative link / knowledge database which is a network database for presenting information according to a user's request.

[Related Art] It is known that a system in which a large amount of information is stored as a knowledge database and the information is retrieved from the knowledge database when the information becomes necessary is useful. A hypertext system is a system that can construct a database flexibly and obtain related information one after another.

As a conventional hypertext device, FIG. 6, FIG.
There is one shown in FIG. FIG. 6 is a block diagram of the configuration of the hypertext device. In the figure, (1) is a hypertext control unit for controlling the entire operation, (2) is a mouse device for controlling a cursor position on a display, and (3) is data. A keyboard device for input, (4) a knowledge database storing various information, (5) a display device for displaying search results, and (6) a printer device.

FIG. 7 shows the display on the screen (16) of the display device of the hypertext device, which is described in the Hyper Card User's Manual (Apple Computer Japan Co., Ltd.). (14) is an information unit from the database displayed on the screen, and is displayed on the screen in the form of a paper tag. The pictures and arrows arranged in the information unit (14) are called icons, and are hit by a mouse or the like to move to the next screen, and are therefore called buttons (13).

FIG. 8 shows the logical structure of the knowledge database (4). The basic information unit (14) of the knowledge database (4) has several buttons (13), each of which is associated with only one other card.
These cards constitute a network as a whole and serve as a knowledge database.

As described above, the hypertext system is a kind of a knowledge database in which the next information unit is connected by associatively linking the button to the information unit.

The operation of this knowledge database will be described. In FIG. 8, it is assumed that the information unit (14) on the screen is a. When the searcher presses the button A, the screen becomes a unit of information. Then, when the button D is pressed, the screen becomes an information unit.

Thus, the user can use the information unit (14) button (13) displayed on the screen (16) of the display device (5).
Is selected using a mouse device (2) or a keyboard device (3), thereby searching for appropriate information in the form of an information unit (14) and displaying it on the screen. I could get the output on a printer if needed.

There is also a system in which a plurality of card parts are collectively displayed on one screen so that the relation can be understood.

[Problem to be Solved by the Invention] In the conventional hypertext device, since the button of the information unit is connected to only one other information unit, the same applies whether the user has advanced knowledge or a beginner. Information units are searched. But this is inconvenient,
It is desirable that the most appropriate card can be searched according to the level of expertise of the user. Utilizing the flexibility of the hypertext system and the easiness of adding and changing information units to a database, the above-mentioned inconvenience is solved while configuring a network database.

That is, it is an object of the present invention to reduce the number of operations for searching a database by a user and to obtain a system capable of searching for information most suitable for a user's specialty level.

[Means for Solving the Problems] The associative link / knowledge database according to the present invention is:
Display means (14) for displaying the selected information, selection means (13) for the user to select information not selected, and display of the selection means and the selected information on the same screen of the display means. Things.

[Operation] In the present invention, since the user level and the knowledge level are compared in the system, an information unit suitable for the user's level is selected and displayed, and the user easily selects the information unit on the screen. be able to.

FIG. 1 is a block diagram showing a configuration of an associative link / knowledge database according to an embodiment of the present invention. In the figure, a hypertext control unit (1), a mouse device (2), a keyboard device (3), a knowledge base (4), a display device (5), and a printer device (6) are the same as those in the related art.
The knowledge database control unit (1) is provided with an information comparison unit (8). Also, the structure of the knowledge base has a new part as described later. (7) is a user management database. FIG. 2 shows the data structure of the user management database (7). The user data (11) registers and stores a user level index (12).

FIG. 3 shows the logical structure of the knowledge base (4) in the embodiment of FIG. In the figure, a new knowledge level index (15) is provided for the information unit (14), which is the information unit of the knowledge base (4). In addition, the information unit (14) to be combined with the button (13) was expanded to a plurality of sheets in some cases.

4 (a) to 4 (c) are examples of three different levels of information units corresponding to buttons having three combinations of information units in FIG.

Next, the operation will be described. FIG. 5 is a diagram showing the operation of the information comparison unit (8) in FIG. 1, and it is assumed that the user 1 whose user level index (12) is 4 is searching in the figure. It is also assumed that the information unit (14) displayed on the screen of the display device is D. When this user presses the information unit button (13) on the screen, this button will display three of A, B, and C.
The information units are combined, and the information comparison unit (8) selects B of the information unit 2 from among them. In this example, from the set (17) of the information units (14), the information unit B having the knowledge level index (15) closest to the user level index (12) is selected.

In correspondence with FIG. 4, the description of the level 5 compact disk of FIG. 4B is selected.

A button (13) corresponding to the information unit that has not been selected is displayed on the screen of the selected information unit.
By pressing this button, the corresponding information unit can be displayed, and the user can obtain higher-level information or more chewed information.

In short, as is clear from FIG.
The displayed information unit (14) and the button (13) corresponding to the information unit not selected and displayed are displayed at the same time, and the user can freely select the information unit on the screen with this button (13). it can.

In this way, the database can be managed in a network format, and the same operation can be performed for any user, and optimum information can be provided for each. No subdivision is required, and operation is easy. The information unit can be added without considering the system, and the modification and abolition of the information unit are as easy as in the past. There is a common information unit for each level, and the database can be made smaller.

In the above embodiment, the registration of the user level index (12) is input from the keyboard. However, the search history of the user is stored in the knowledge database control unit, and the average of the knowledge level of the information unit in the history is used. The system can also change the user level index of the user.

[Effects of the Invention] As described above, according to the present invention, the user level index and the knowledge level index are provided, and information is retrieved from the relationship between them, so that appropriate information can be presented to the user. At the same time, the user can easily select and display the searched and displayed information on the screen. Therefore, the user can obtain the most necessary information.
