Abstract

PURPOSE:To refer to only the necessary information effectively and in detail by designating the slot of an object desired by a user for its detailed display. CONSTITUTION:A command that designated both object and slot names is inputted via an input device 5 as a user input, and this command is analyzed by a command interpreting part 6 to obtain the specific object and slot names that are desired by the user in detail. A knowledge base control part 2 receives both object and slot names and retrieves the detailed information out of an object type knowledge base for a specific slot of a designated specific object. Thus it is possible to designate the slot desired by the user when the internal information on the object is displayed. As a result, the user can refer in detail to only the necessary information in a short time.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a knowledge base display system that displays an object-type knowledge base.

(Conventional technology) In the knowledge representation method of the object type knowledge base,
Maintain multiple slot-value pairs within an object.

At this time, by entering another object name as the value of the slot, the plurality of objects constitute a network with the slots as links.

One method of displaying information held by each object in such a knowledge base, such as information such as slot-value pairs, on the display and presenting it to the user is to specify the object name you want to display and display that information as a knowledge base. There is a way to get it from the base and display it. At this time, if the object name is written as the slot value of the specified object and the objects form a network, there is a method to display only the object name which is the slot value, and to display all the internal information of the object. There is a method for displaying the slots in more detail.

However, according to the former method, only the name of the object that is the slot value is displayed, so it takes time and effort to specify and display the object again in order to view its contents. Also, according to the latter method, if the specified object has a large number of slots and slot values, there is too much information to display and it cannot fit on the screen, so in the end, it is necessary to display each one one by one using the former method. Sometimes. It also displays information about slots and values that the user does not need, which wastes resources.

(Problem to be Solved by the Invention) In other words, according to the conventional method, there is no means for specifying the information that the user needs, and there is a problem in that it is not possible to display the information that the user wants to see in the necessary amount and without waste. did.

The present invention is directed to the above ll! It is an object of the present invention to provide a knowledge base display system that is equipped with a means for specifying information that a user needs and can display as much information as necessary.

[Structure of the invention]

(Means for Solving the Problems) The present invention is an object type that expresses the target world by expressing knowledge about each object as an object consisting of slot-value pairs, and by connecting each object in a network through the slots. a knowledge base; a knowledge base management unit that accesses the object-type knowledge base and manages knowledge; and a knowledge display unit and an output device that display the contents of the object-type knowledge base, that is, information held by each object.

The present invention is characterized in that an input device for receiving and receiving command input from a user and a command interpreter are configured as follows.

That is, a command specifying an object name and a slot name is input as a user input from the input device. This is analyzed by the command interpreter to obtain the specific object name and slot name that the user wants to see in detail. As a result, the knowledge base management unit searches for detailed information from the object type knowledge base for a specific slot of a specified specific object. This information is, for example, information about the slot itself of the first designated object, or internal information about the object written as a value in this slot. The checked information is sent to the knowledge display section and displayed by the output device.

(Function) According to the present invention, when displaying the internal information of an object, the user can specify the slot that he or she wants to view, so that only the necessary information can be viewed in detail. There is no shortage or excess of information, so it is possible to see only the necessary information without having to take the trouble of redisplaying information that is not displayed or overflows from one screen. Furthermore, resources are not wasted by displaying information that the user does not need.

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

This system is an object type knowledge base 1.

It is composed of a knowledge base management section 2, a knowledge display section 3, an output device 4, an input device 5, and a command interpretation section 6.

The object type knowledge base 1 stores object knowledge. Each object is a knowledge consisting of multiple slot-value pairs, and values can contain other object names. As a result, a plurality of objects constitute a network using slots as links.

The knowledge base management section 2 is composed of a knowledge base access control section 7 and a working memory 8. The knowledge base access control unit 7 accesses the object-type knowledge base 1 to test necessary knowledge, make inferences based on the tested knowledge, and make changes. At this time, intermediate results are stored on the working memory 8.

The knowledge display unit 3 refers to the object information stored in the 1-work memory 8 and displays it on the output device 4.

Commands to the knowledge base management section 2 are inputted via the input device 5 and passed to the command interpretation section 6 for analysis. When the command interpreter 6 recognizes the object display command, the command interpreter 6 further investigates and specifies which slot of which object the detailed information is to be displayed.

This analysis result is sent to the knowledge base access control unit 7, and the object information necessary for one display is checked from the object type knowledge base 1, temporarily stored in the working memory 8, and then displayed in the knowledge display unit 3. Displayed by

FIG. 2 shows an example of objects to be displayed.

Several objects are shown here, and each object has the name of another object as its slot value, and the objects form a network. for example"
The "file deletion-1" object is connected to the rrm-comn+and-IJ object via the command slot. Also, a file that is connected to the rfile-IJ object via the file slot.
rfile-IJ object also has owner
It is linked to the ruser-IJ object through a slot.

What is expressed by the network of objects in this example is that ``File deletion is realized by the 1m command.The specific file deletion (file deletion-1) in question is:

The purpose is to delete a specific file file-1, whose file name is "foo, 1isp" and whose owner (slot owner) is user-1. The login name of the owner user-1 is “muranag”
a” and the group name is “AI”.”

When the above knowledge base exists, a sentence as shown in FIG. 3(a) is input to display one object. The first print-object-detail is the command name, and the object name and slot name are specified by the first and second arguments of this command (here, "file delete-1" and "fileJ") *
The object contained in the slot of the specified object as a value (here rfile-IJ)
Internal information is also checked and displayed at the same time. The display result is shown in FIG. 3(b). Further, when a command as shown in FIG. 4(a) is input, a display as shown in FIG. 4(b) is displayed. This is an example of a command specification format that displays the object written in the slot value in detail, as well as detailed information about the slot itself. Object information corresponds to the part surrounded by [ and ], and slot information corresponds to the part surrounded by ( and ).

FIG. 5 shows the syntax of the display command. Kodeku Flag〉
is for specifying whether or not to display detailed information, and yes or no is specified.

: The flag immediately after 5lot specifies whether to display the detailed information of the slot, and the flag immediately after value specifies whether to display detailed internal information of the object written as the slot value. is specified. In FIG. 3, only the value flag is YES, and FIG. 4 is an example in which both flags are YES. If either flag is no, it is displayed in the simplest format as shown in FIG.

The processing in this embodiment will be described next. FIG. 7 shows a processing flow of the command interpreter 6 that analyzes display commands.

When a command is input by the user, the command interpreter 6 starts reading the command line (11). Read the first word (12) and use it as the command name (here pri
nt-object-detail) examines (13)
, otherwise it jumps to that processing routine as another command (14). If so, read the first word,
This is recognized as the object name that the user wishes to display in detail (15). Furthermore, the next word is read and recognized as the slot name of the slot that the user wishes to display in detail (16).

Read the next word and check whether it is 5lot (17), otherwise jump to syntax error processing (21), if it is 5lot, check whether to display the 5th word in detail. V
& Understand (18), then read the next word.

Check if it is: value (19). Otherwise, the process jumps to syntax error processing (21). If: v
If it is ``alue'', the next word is recognized as a flag indicating whether to display the slot value in detail (
20).

Using the above command analysis results, the knowledge base access control unit 7 accesses the object type knowledge base and searches for information necessary for display. The processing flow is shown in FIG.

First, information on the specified object name is retrieved from the object type knowledge base 1 and stored in the working memory 8 (
31) If the flag indicating whether to display the slot in detail is yes (32), the information of the specified slot of the specified object is retrieved from the object type knowledge base 1 and stored in the working memory 8. Store it in (33),
Also, a flag indicating whether to display slot values in detail is set to ye.
s (34), and the slot value represents an object name (35), then the information about the object that is the slot value is stored in the object type knowledge base 1.
The information is further examined and stored in the working memory 8 (36).

In this way, the information necessary for display (that the user wants to display) is stored in the working memory 8, and the knowledge display section 3 displays the object on the output device 4 by referring to this information.

According to the embodiments described above, the user can specify the slot of the object that he or she wants to display in detail, so that only the necessary information can be viewed in detail. In other words, there is no shortage of displayed information or too much information. This makes it possible to view only the necessary information without having to take the trouble of redisplaying information that is not displayed or overflows from the screen. Furthermore, resources are not wasted by displaying information that the user does not need.

In the above embodiment, only the object and the slot were specified, but it is also possible to specify even the object name written as a slot value as shown in FIG. 9. This is effective for not displaying unnecessary information in the case of a knowledge base where multiple slot values can be described.

Furthermore, as shown in FIG. 10, it is also possible to designate a plurality of slots.

Furthermore, as shown in FIG. 11, when objects are recursively connected, by specifying the slot path to be followed, it is possible to extend the display to any level that can be recursively displayed.

The expansion described above makes it possible to specify and display information required by the user more flexibly.

〔Effect of the invention〕

As described above, according to the present invention, the user can specify the slot of the object that he or she wants to display in detail, so that only the necessary information can be viewed in detail. In other words, the displayed information is neither insufficient nor too much. This makes it possible to efficiently view only the necessary information without having to take the trouble of redisplaying information that is not displayed or has overflowed from the screen.

Furthermore, resources are not wasted by displaying information that the user does not need.
