Abstract

PROBLEM TO BE SOLVED: To improve the reliability of the whole knowledge by introducing document representation and a table and also displaying description contents hierarchically, and then making it efficient to find a description omission and a miss by making it easy to understand the knowledge. SOLUTION: When a user selects knowledge to be displayed or edited, a knowledge display means 2 which uses document form representation displays the knowledge contents and displays an upper or lower layer of part or the whole of the displayed knowledge on the basis of hierarchy management information managed by a document form hierarchy management part 7. Further, detailed contents of terms at a specified part or relative information are displayed on the basis of term information managed by a knowledge term management part 8. Further, the hierarchy management and term management are automatically updated according to editing operation. Then a knowledge translating means 5 converts the knowledge contents in document form representation to a program form that can be called directly from inference execution or a form which can be referred to by an inference execution part according to the term management information.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing system, and more particularly, to a knowledge information processing technology (artificial intelligence technology), and in particular, to make a traveling maintenance plan for train schedules, crew schedules, elevators, etc. in transportation. Such as
The present invention relates to an information processing system suitable for advanced scheduling planning.

2. Description of the Related Art Conventionally, a US patent "Basic Expert" has been used.
System Toool "Technowlegdge Company Steven Hardy, 1
It is known to describe knowledge by rules and infer using it, as described in US Pat. No. 4,648,043, Mar. 3, 987. Furthermore, in addition to the description of rules, the purpose for using these rules, the achievement policy / means, etc. are described as a strategy, and the rules are executed based on the strategy selected according to the set purpose, As an information processing system for advancing inference, Japanese Patent Application Laid-Open No. 62-247838 "Information Processing System", and as an input / editing method for description of knowledge such as purpose and strategy, Japanese Patent Application No. 6-281672 "Knowledge editing method" And Japanese Patent Application No. 7-2395182, "Information Processing System".

[0003]

Among the above techniques, the known examples in the United States regarding description of knowledge by rules are as follows.
Since the description of the purpose and execution means for inference execution, and the description of another method when a problem occurs in inference execution are all described as rules, these are mixed and it is difficult to understand and confirm the description and trust. Problems tend to occur from the viewpoint of sex. In addition, when dealing with a target that has a large number of combinations, such as a train schedule for transportation or a crew schedule, and the processing is complicated, the number of rules to describe becomes huge and the problem of processing capacity easily develops. was there. As a means for solving this, the technologies of the above "information processing system" and "knowledge editing method" have been devised. According to this technique, it is possible to separate the purpose and strategy for executing problem solving and planning from the rules necessary for execution, and to describe both by associating them with each other. Further, as shown in FIG. , It is possible to set multiple strategies for the objectives in order of priority by using the objective / strategy net in which the correspondences of the objectives / strategy are connected by AND or OR, and to set the multiple subordinate objectives for each strategy , It is possible to divide difficult problems into simple problems and organize them, and to change the strategy according to the situation, and to plan a well-balanced plan in which the lower objectives are coordinated. In this purpose / strategy net, the "knowledge editing method" and "information processing system" described above allow visual addition / change of the connection between the purpose and the strategy.

However, in the above-mentioned prior art, of the knowledge necessary for inference, the upper knowledge can be represented by the above-described purpose and strategy configuration, but lower knowledge such as rules necessary for execution can be used. With regard to knowledge, the number of combinations will be huge due to the different situations and conditions required for inference execution,
Expression by the composition of purpose and strategy becomes practically difficult in a real system.

For this reason, at present, the representation of the portion where the inference means uses these lower-level knowledge at the time of inference execution remains the program representation that the inference means can directly call, and the description format is procedural. , The meaning as inference knowledge is difficult to understand, and there are many combinations due to various situations and conditions, so there is a large amount of knowledge description. For this reason, overall understanding and associating the whole with each part are performed. There was a problem that it was a factor of lowering the reliability because the efficiency was lowered and it was difficult to check the description contents.

Further, since the knowledge description is a procedural expression, it is necessary to separately create a document with a textual expression as an explanatory material. For this purpose, man-hours for preparation and maintenance of the document accompanying improvement / correction of the knowledge description are required. There is a problem that the management man-hour is large and the reliability of the document is deteriorated due to omission or mistake in the maintenance process.

An object of the present invention is to provide a visual expression means for easily grasping the contents of all knowledge necessary for inference in order to solve the above-mentioned problems of the prior art, and the knowledge necessary for inference. By integrating the description of the document and the document to help understand it, by facilitating the understanding of the knowledge and improving the efficiency of discovery of description omissions and mistakes,
It is to improve the reliability of the entire knowledge.

[0008]

In order to achieve the above object, the present invention enables the introduction of a sentence expression or a table in which kanji and kana are mixed as in a general document for the knowledge necessary for inference execution. It has means for displaying and displaying knowledge based on the representation in the hierarchical document format, using the means for registering / quoting terms and managing the hierarchical structure of the document to enable the hierarchical display of the description contents. Moreover, it is achieved by having a means for editing the knowledge by adding / changing / deleting these description contents.

Further, the knowledge expression described in the above document format is referred to from a program format which can be directly called at the time of inference execution by means of managing terms used in the expression, or from an inference execution section. By providing a means for translating into a possible format, inference using knowledge from this document format representation or inference with knowledge from this document format representation and knowledge of other formats is achieved.

Specifically, when the user selects the knowledge to be displayed or edited, the knowledge display means in the document format representation of the present invention displays the knowledge content, and the user gives an instruction to move up or down the hierarchy. By doing
Based on the hierarchy management information managed by the document format hierarchy management means, the upper part or the lower part of the displayed knowledge part or the whole is displayed. Further, when the user designates a specific portion of the displayed knowledge, the detailed contents of the term of the designated portion and related information are displayed based on the term information managed by the knowledge term management means. Furthermore, when the user specifies the knowledge edit, it is possible to change / add / delete or copy / move the display knowledge in character units and line units, and update the hierarchy management and term management based on the editing operation. It is done automatically. For example, when the display knowledge is changed to another term, the confirmation operation screen for that term is displayed, and when a new term occurs, the registration operation screen for that term is displayed. Then, a new term is registered in the term management information. When the description content related to the hierarchical structure is changed, the hierarchical management information is updated and redisplayed accordingly.

Next, when the user specifies the automatic translation of the knowledge, the knowledge translation means uses the term management information managed by the term management means for the knowledge content in the document format representation to directly execute the inference. It is converted into a callable program format or a format that can be referenced by the inference execution unit. As a result, when performing inference, not only knowledge by document format representation but also inference execution by mixing with knowledge of other formats is possible.

The knowledge management means 4 is attached to the external storage unit 14 or formed in the external storage unit 14, and the knowledge translation unit 5 and the inference execution unit 6 are attached to the processing unit 12 or formed in the processing unit 12.

FIG. 3 shows a specific example of hierarchical display in the knowledge display by the document format representation of the present invention.
The figure (a) shows the display screen 31 of all the knowledge display levels, the figure (b) shows the display screen 32 of the general knowledge display level excluding detailed information, and the figure (c) shows the section level display. The screen 33 and the figure (d) show the chapter level display screen 34. To switch between the screens, the user selects the hierarchy change 35 from the menu at the top of the screen to display the submenu 41 for changing the hierarchy display shown in FIG. 4, and further select a specific menu from the submenu 41. It becomes possible by doing. For example, in the screen of FIG.
After selecting 5, when selecting the whole hierarchy up 42 or the partial hierarchy up 43 of FIG. 4, the display is switched to the display of only the general knowledge as shown in the screen of FIG.
After selecting 5, if the entire hierarchy down 44 or the partial hierarchy down 45 of FIG. 4 is selected, the detailed knowledge that was not displayed is displayed again and the screen of FIG. 3A is restored.
In addition, the whole hierarchy up 42 and the whole hierarchy down 44 of FIG.
At the time of selection, the hierarchical display is switched over for the entire knowledge in the document format representation, and at the time of selecting the partial hierarchy up 43 and the partial hierarchy down 45, a portion of the displayed knowledge centering on the knowledge in which the character cursor 39 exists. Switching of the hierarchical display will work for the specific range. FIG. 5 is an example of the structure of a hierarchy management table 61 for performing hierarchy display, which is composed of a hierarchy number 63 for each row 62 of knowledge expressed in a document format and a display state 64 indicating whether or not it is being displayed. . Layer number 63 is created by knowledge
When edited, as shown in the knowledge representation example in Figure 3, "chapter"
It is automatically set based on the reserved words related to the hierarchy such as "," and "section". In addition, the display state 64 is set to “displaying” in the state of FIG. 3A, and as shown in FIG.
When the hierarchy is switched up or down, the display state 64 of each row is set to "displaying" or "non-displaying" based on the value of the hierarchy number 63. For example, when the layer up is designated, the display state 64 of the row having the largest layer number 63 among the rows whose display state 64 is "displaying" is set to "non-display", and conversely, the layer down is designated. Then, the display state 64 of the line having the smallest layer number 63 among the lines whose display state 64 is "non-display" is set to "displaying".
Based on the display state 64, only the "displaying" line is displayed and the hierarchical display is switched. In the case of partial hierarchy switching, the display state 6 described above is applied only to lines within a limited range centered on the line where the character cursor 39 is present.
4 is updated and the display is switched.

FIG. 6 shows a specific example of related information display in the knowledge display by the document format representation of the present invention. On the knowledge display screen 46, when the user designates specific display information with the pointing device 20 such as a mouse, information related to the display information is displayed in the related information display child screen 47.

It should be noted that selection of the edit end menu 56 of FIG. 7 returns to the normal screen of FIG. The displayed knowledge can be changed on any of the screens shown in FIGS. 3, 6 and 7, and the character cursor 39 can be moved to move the keyboard 1.
Knowledge can be changed by inputting or changing from 9 to the character cursor position. As a result of the change of knowledge, the term used for describing the knowledge is checked, and as shown in the display screen example of FIG. 8, when the term is changed to an existing term, the term confirmation child screen 48 is displayed. , The definition contents already defined for the term can be displayed and confirmed, and when the term is changed to a new term, a new term registration screen 49
This makes it possible to input new definition content for the term. Terms are checked based on the term table 91 that collects terms as shown in FIG. 12, and the designation of the term table 91 to be used is performed as shown in the knowledge description example of FIG. It is based on the description of reserved words such as "Term:" and "Internal term of this section:". As shown in this example, since a plurality of term tables 91 can be used in the knowledge information represented by one document format expression (hereinafter, simply referred to as a document), the effective line range for each term table 91 is shown in FIG. Term table management table 7 as shown in
Manage by 1. The term table management table 71 includes a term table name 72, a valid start line 73, and a valid end line 74.
A valid line range is set for each term table.

Next, in the display screen of FIG. 3, when the user selects the translation menu 37 at the top of each screen, the knowledge in the document format representation is translated into a format that can be used during inference. Be seen. FIG. 10 shows a specific example thereof. FIG. 10A shows an example of knowledge based on a document format representation before translation, and FIG. 10B shows an example of knowledge that can be used at the time of inference execution after translation. , Arrows correlate both knowledges. This example shows a case where the inference execution means 6 translates the knowledge in the document format expression into the format of a program that can be directly called when the knowledge is required for the inference execution. In addition, in the display screen of FIG. 3, after the user specifies the range of knowledge, the translation menu 3
When 7 is selected, the display of the translation content is limited to the range-specified portion, and partial translation is also possible. FIG. 11 is a configuration example of the translation management table 81 created when translating knowledge in a document format expression.

When the translation is designated for the specific range as described above, the translation corresponding line 83 corresponding to the line 82 of the range designated by the translation management table 81 is taken out and the translation result of only the range is displayed. It

FIG. 12 shows an example of a term table 91 used in the related information display of FIG. 6 and the knowledge translation of FIG. The term is an element for expressing knowledge by the description in a normal sentence or table in the document format expression according to the present invention, and as shown in FIG.
And the definition content 93 is set. This is shown in FIG.
As shown in, the user sets or updates the term confirmation child screen 48 and the term new registration child screen 49. Further, in FIG. 12B, the term 92 and the definition content 93 are shown.
The correspondence is not unconditional, but the correspondence with the definition content 93 is different depending on the definition condition 94 in which the term 92 is used. For example, in the example of the term table 91 in FIG. 7B, the term 92 “working time evaluation” is “work style”.
The definition condition 94 indicates that the corresponding definition content 93 is different. Further, when the definition condition 94 is not dependent, it is possible to set the definition condition 94 to “common”. Further, in the example of the term table 91, if all the defining conditions 94 are “common”, the column of the defining condition 94 can be omitted. In that case, the example of the term table 91 of FIG. Will be done.

Next, the operation of each means of FIG. 1 relating to the above screen operation and table management will be described with reference to the flow charts of FIGS. 13 to 14.

In the information processing apparatus 1, when a user who wants to refer to knowledge activates the knowledge display means 2 in FIG.

The translated knowledge information is fetched from the external storage device when the inference execution means 6 is needed when the user who intends to execute inference in the information processing apparatus 1 activates the inference execution means 6. Will be used. The inference executing means 6 can be realized by "information processing system" of JP-A-62-247838.

Next, regarding the details of the translation processing in S81,
This will be described with reference to the flowchart of FIG. However, in this example, when the inference execution means 6 needs knowledge for inference execution, it describes the case of translating the knowledge in the document format expression into the format of the program that can be directly called, and therefore, as shown below. In addition, it is assumed that the whole document is expanded into one function.

When the knowledge translation means 5 in FIG. 1 starts the knowledge translation, the knowledge in the document format expression is taken out line by line (T1), and as shown in FIG. 10, the process according to the reserved word contained in the line is performed. Perform (T2). For example, for the reserved word "document name:", the term that becomes the document name is extracted (T3), the comment line is generated (T4), and the term table 91 is searched to obtain the character string that becomes the function name. (T5), and for the reserved word "XX internal term:", the term table name is extracted (T6), the term table 91 is retrieved from the external storage device 8 (T7), and the term Set a valid row range in the table management table 71 (T
8). With respect to the reserved word "evaluation item:", a term to be the evaluation item 86 is extracted (T9), and for each evaluation case 84 continuing from the line next to the line in which the reserved word "evaluation item:" exists. The valid term table 91 is searched for a term representing the evaluation condition 85 and a term serving as the evaluation item 86, and the term 92 is searched.
It is developed as a condition of the if sentence based on the definition content 93 corresponding to (T10). One if statement is constructed for each evaluation case, and NG is returned as a return value when the condition is satisfied.
A turn sentence is added (T11), the translation for one evaluation case is completed, and the number of evaluation cases for one evaluation item is repeated (T12). Other reserved words are expanded as comment lines (T13), and the above process is repeated for each line of knowledge until a reserved word indicating the end of knowledge information (“above” in the example of FIG. 10) is detected. . When the translation of one line of knowledge information is completed, it is accumulated as translated knowledge (T14), and the translation corresponding line 83 is set in the translation management table 81 of FIG. 11 corresponding to the knowledge line 82 (T15). ). If a reserved word indicating the end of the knowledge information is detected, an end mark (“}” in the example of FIG. 10) is added to the end of the translated knowledge information (T1
6), end the process. In the above example, an example of translation for four types of reserved words is given, but it is possible to provide other reserved words as the language specification of knowledge by the document format expression.
