Abstract

PURPOSE:To extremely improve the interactive efficiency with a system operator by selecting and transmitting only the data processing results that are expected or desired by the system operator out of those results obtained by an arithmetic processor. CONSTITUTION:An operating vector inference mechanism 22 infers the directions desired by a series of inputs given from a system operator based on the information on an operating history holding mechanism 21 as well as the knowledge which is used to specify the operating direction of a knowledge base mechanism 23. A filtering mechanism 24 transmits only the information approximate to the operating direction shown by the mechanism 22 out of those data processing results corresponding to the input data. The present input data is sent to the mechanism 22 via the mechanism 21 and undergoes the correction for the operating direction inference result preceding the present input. The mechanism 24 filters the data processing result of the present input based on the operating direction inference result to which the present input is reflected. Thus it is possible to select and deliver only the necessary data processing results and to extremely improve the interactive efficiency with the system operator.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a man-machine dialogue system, and particularly to a man-machine dialogue system in an information processing system.

[Conventional technology]

FIG. 3 is a block diagram showing a conventional man-machine dialogue system.

A conventional man-machine dialogue system 31 in an information processing system includes a data input device 32, an arithmetic processing device 33, and a data output device 34, as shown in FIG.

Among these, data input devices 32 include a character keyboard and a tablet stylus.

A mouse or a function keyboard is used, and the data output device 34 is a CRT such as a character display device or a graphic display device.
A display device is used.

The arithmetic processing unit 33 performs necessary data processing on the data input by the data input device 32, internal data held within the arithmetic processing unit 33, and predetermined procedures. The results of the data processing are sent to the data output device 33 according to a predetermined procedure for output and displayed as information that can be known by the system operator 36.

Therefore, the system operator 36 visually recognizes the response displayed on the data output device 33, grasps the obtained information, and determines what input should be made next. Then, the system operator 36 again makes the next input that he considers optimal.

By repeatedly performing such operations, the system operator 36 can accomplish the desired task.

In conventional man-machine dialogue systems, a set of commands that can be accepted as input data is prepared in advance, and each command is accompanied by several parameters.

Input to a conventional man-machine dialogue system is performed by selecting one of a set of commands, giving values to parameters that should accompany the command, and typing the data.

Similarly, the output content and format of output from conventional man-machine dialogue systems are predefined for each command input and accepted.

Therefore, the final output information in accordance with the output format specified by the command is determined by the input command and its parameters and the internal state of the arithmetic processing unit of the conventional man-machine dialogue system. Become.

[Problem that the invention seeks to solve]

In such a conventional man-machine dialogue system, the system operator is required to fully understand the details of the output format for each command defined in the summary system.

Understanding the details of the output format for each command defined by the system presupposes an understanding of the functionality provided by the system and the set of commands it accepts.

Furthermore, since a large amount of information is output as output information, the system operator needs to extract and select the desired information from among them.

These things place a heavy burden on the system operator, as it requires skill to use the conventional man-machine dialogue system.

Further, the output content and output format of the processing results of individual commands accepted by the system are designed to be closer to the format and information desired by the system operator through optional functions.

However, this also has the disadvantage of increasing the amount of information that system operators must remember and understand when using conventional man-machine interaction systems.

The purpose of the present invention is to solve such problems, to delete the output of noise information that is unnecessary for the system operator, and to select and output only the information that the system operator wants, based on the system operator's input at that point in time. The object of the present invention is to provide a man-machine dialogue system that greatly improves the efficiency of dialogue with a system operator.

[Means for solving problems]

The man-machine dialogue system of the present invention includes a data input device used by a system operator to input data, an arithmetic processing device that performs necessary data processing on the data input with this data input device, and a a knowledge filter device that selects and passes only the data processing results that the system operator expects or needs from among the data processing results by the processing device; and a data output device that outputs information that can be known.

[Effect]

The output of a man-machine dialogue system is based on the input made by the system operator and the internal state at that time.

A system operator usually performs a series of inputs for a certain purpose. The measure for determining one input made by a system operator is the difference between the desired state intended by the system operator and the internal state of the system created by a series of inputs previously input to the system.

The system operator attempts one of the functions provided by the system to compensate for this difference.

Among the information sent by the tried function, information that has a direction different from the previous difference is nothing more than noise to the system operator at that time.

At this time, the system operator's attention is focused only on the above-mentioned difference that he is trying to fill among the effects that all the functions he has tried have on the system.

The information that a system operator expects or needs when a single input is made can be inferred by reading the flow and context of a series of inputs made by the system operator so far.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the man-machine dialogue system of the present invention.

In FIG. 1, the man-machine dialogue system 1 of this embodiment
is composed of a data input device 2, an arithmetic processing device 3, a data output device 4, and a knowledge filter device 5.

FIG. 2 is a block diagram showing the contents of the knowledge filter device included in this embodiment.

As shown in FIG. 2, the knowledge filter device 5 includes an operation history holding mechanism 21, an operation vector inference mechanism 22, a knowledge base mechanism 23, and a filtering mechanism 24.

Data input by the system operator 6 is sequentially stored in the operation history holding mechanism 21.

The operation vector inference mechanism 22 uses the operation history holding mechanism 2 based on the knowledge for specifying the operation direction of the knowledge base mechanism 23.
1, the direction in which the series of inputs given by the system operator 6 is aimed is inferred.

The filtering machine 111I24 selects the direction of the operation indicated by the operation vector inference mechanism 22 based on the knowledge of the knowledge base mechanism 23 for specifying the direction of the information from among the data processing results for the data input by the system operator 6. Only similar information is passed.

The current input, which is data input by the system operator 6, first passes through the operation history holding mechanism 21, and then is sent to the operation vector inference mechanism 22.
The operation direction inference result before the current input of 2 is corrected.

Then, based on the operation direction inference result of the operation vector inference mechanism 22 that reflects this current input, the filtering mechanism 24 performs filtering on the data processing result of the current input.

Among the knowledge that specifies the operating direction of the knowledge base mechanism 23,
By adding knowledge about interrupt operations, even if the interrupt data input at one time is unrelated to the previous series of operations, it is possible to later return to the original series of operations. It is possible.

〔Effect of the invention〕

By being configured as described above, the man-machine dialogue system of the present invention selects and outputs only the data processing results that the system operator expects or requires, greatly increasing the efficiency of dialogue with the system operator. This has the effect of making it possible to build an application system that is easy to use and has good operability.
