Description

Information processing device, program and information processing method

The present disclosure relates to an information processing device, a program, and an information processing method.

Instead of conventional document-based system development such as specifications or design documents, use description languages such as SysML (Systems Modeling Language) or UML (Unified Modeling Language) to design while creating a system model MBSE (Model Based) Systems Engineering) is attracting attention.

In document-based system development, system designers create specifications or design documents that include the designed information while designing the system. On the other hand, in MBSE, a system designer constructs a system model including designed information using a tool called a modeling tool, which corresponds to MBSE, while designing the system.

A system model is a DB (Data Base) that stores system design information. The design information stored in the DB is general system design information such as a list of system components, external interface information of each component, and information on data exchanged between each component.

A modeling tool is a tool for viewing, creating, or updating a DB that stores system design information, and can output a system model that is a DB that stores system design information.

While document-based system design deliverables are specifications or design documents, system design deliverables in MBSE are system models constructed using modeling tools. A system model is treated as a single source of truth for design information.

The system model comprehensively holds system design information. Therefore, when a person concerned with the system wants to browse the design information related to his or her responsibility, it is necessary to search for the necessary part from the huge amount of design information in the system model, which takes time and effort. The necessary place here is the place where "design information related to own responsibility" is stored.

Also, since the system model can be viewed using a modeling tool, viewing design information poses the problem of licensing the modeling tool or learning how to use the tool.

Therefore, it is conceivable to extract the range related to one's responsibility from the system model and output it to the document. For example, when creating a design document for a new function added to the system, design information for the new function is output from the system model to generate a design document for the new function. Also, when creating a system interface specification, the interface specification is generated by outputting design information related to the system interface from the system model.

Patent Document 1 discloses a technique for creating software specifications by outputting information necessary for creating software specifications from a system model containing software design information. The information necessary for creating the software specification here is the design information described in the software specification. A document can be generated from a system model by using the technique described in Patent Document 1.

JP 2005-258561 A

Now, let's consider the review that the designer does after designing new system functions and adding the designed information to the system model. When a review is performed asynchronously by e-mail or a review support tool instead of face-to-face, first, a reviewer who is a designer outputs design information on new functions from the system model to a document. A reviewer then reviews the document.

At this time, if the reviewer finds a design error and needs to correct it, the designer corrects the system model, which is the Single Source of Truth of the design information, not the reviewed document.

However, the technology described in Patent Document 1 does not present the internal correspondence between the system model and the generated document. Therefore, in order for the reviewer to correct the design error, it is necessary to find out from the system model the part corresponding to the design error pointed out by the reviewer.

In other words, since the reviewer reviews the document by looking at it, they can present the location in the document where the design error is described, but they cannot present the corrected part in the system model. Therefore, the reviewer searches for the correction part in the corresponding system model from the position in the document that can be presented by the reviewer, and makes the correction.

For this reason, it may take time to search for the corrected part in the corresponding system model from the position in the document.

In addition, even if the reviewer searches the system model using a character string search based on the indication, it takes time to search for the correct correction part from among a large number of search results. There is a risk.

Specifically, when a reviewer finds a design error in an API (Application Programming Interface) named "get" in the software within the system, the designer searches the system model for the character string "get", Search for the fix. However, if the API named "get" exists in multiple classes, "get" in each class will be the string search result. Therefore, it is necessary to further search for "get" pointed out as a design error.

Furthermore, many of the document generation functions that output documents from system models, which are implemented by general modeling tools, do not present the internal correspondence between documents and system models. The reason for this is that, as described above, the design information in the system model is premised on access such as browsing using a modeling tool.

Therefore, an object of one or more aspects of the present disclosure is to identify a correspondence relationship between a document and a system model from which the document is generated.

An information processing apparatus according to an aspect of the present disclosure is a system model having a tree structure consisting of a plurality of elements, and a document generation rule that specifies positions for arranging necessary elements among the plurality of elements.

Embodiment 1.
FIG. 1 is a block diagram schematically showing the configuration of a development support device 100 as an information processing device according to Embodiment 1. As shown in FIG.
The development support device 100 includes a system model storage unit 101, a document generation rule storage unit 102, a document generation unit 103, an output unit 104, an input unit 105, an indication target element search unit 106, and a system model correction unit 107. and a post-correction system model storage unit 108 .

In Embodiment 1, an example of the development support device 100 for a system model including system design information is shown as an example, but the information included in the system model does not have to be system design information. For example, the system model may include information related to the life cycle of the system, such as system project management information or verification information.

The system model storage unit 101 stores system models.
FIG. 2 is a schematic diagram showing an example of a system model according to Embodiment 1. FIG.
The system model 110 shown in FIG. 2 shows an example including design information about sw (software) of the system.
The system model 110 is organized in a tree structure, and each node of the tree is called an element. Each element has metadata such as element name, type and notes.

For example, element 111, which is the root element of the tree structure of system model 110, has metadata of element name "sw structure", type "package" and note "xx1".
The type "package" means an element for grouping multiple elements.
Also, notes can store arbitrary strings, and notes are used to record additional information about an element.

Next, child elements of element 111 will be described.
The element 111 has an element 112 of "classA", an element 113 of "classB" and an element 114 of "classC" as child elements. The type of these

elements

112, 113, 114 is "block". The type "block" means a component of a system or a system.

In the system model 110, the "classA" element 112, the "classB" element 113, and the "classC" element 114 are class components that constitute software. Thus, the software of the system has class components of element 112 of "classA", element 113 of "classB" and element 114 of "classC".

Furthermore, the "classA" element 112 has a "get" element 115 as a child element. The type of element 115 of "get" is "operation". The type "operation" means that it is a method of the class component that is the parent element. Therefore, the element 112 of "classA" has the element 115 of "get" as a method as a child element.

Also, the "sw structure" element 111 has the "sw structure diagram" element 116 as a child element. The type of the element 116 of the "sw structure diagram" is "block definition diagram". The type "block definition diagram" is an element that contains a diagram representing the structure of the system. Thus, element 116 of the “sw structure diagram” holds diagram 120 .

FIG. 3 is a schematic diagram showing a diagram 120 included in the system model 110. As shown in FIG.
In MBSE, a block definition diagram represents the structure of the system using the elements in the system model. For example, as shown in FIG. 3, FIG. 120 shows that "classA" and "classB" are related, and that "classA" and "classC" are generalized. express something. Thus, relationships between elements within the system model 110 are known.

Returning to FIG. 1, the document generation rule storage unit 102 stores document generation rules. The document generation rule designates the positions of the required elements among the multiple elements included in the system model. The necessary elements here are the elements used for document generation. For example, when a sw structure diagram is to be described in a document, an element 116 of "sw structure diagram" exists as a necessary element.

FIG. 4 is a schematic diagram showing an example of document generation rules.
In the document generation rule 130 shown in FIG. 4, the part enclosed in brackets indicates that the corresponding content from the system model stored in the system model storage unit 101 is to be output to the corresponding part of the document. , and character strings not enclosed in brackets [ ] indicate that they are to be output as is to the corresponding part of the document.

Note that the description notation of the document generation rule depends on the document generation unit 103. The document generation function is often included in the modeling tool, and in that case, the description notation of the document generation rule conforms to the specifications of the modeling tool.

Here, it is desirable for the document generation rule to divide the generated document by multiple item numbers. For example, in FIG. 4, item numbers include "2" indicating a chapter and "2.1" and "2.2" indicating sections within the chapter.

Returning to FIG. 1, the document generation unit 103 reads the system model from the system model storage unit 101, reads the document generation rules from the document generation rule storage unit 102, and generates a document according to them. For example, the document generation unit 103 analyzes document generation rules and outputs information in the system model to a document based on the analysis results.

Here, processing in the document generation unit 103 will be described, taking as an example the case where the document generation unit 103 reads the system model 110 shown in FIG. 2 and the document generation rule 130 shown in FIG.
Note that FIG. 5 is a schematic diagram showing an example of the document generated by the document generation unit 103 in the above example.

For example, the document generation unit 103 inserts the element 111 in the system model 110 in the area of the document 140 (see FIG. 5) corresponding to the part described as [insert the note of <sw structure>] in the document generation rule 130. Outputs the contents of the note of the "sw structure".

In addition, the document generation unit 103 inserts an element 116 in the system model 110 in an area of the document 140 corresponding to a portion described as [insert a diagram of <sw structure/sw structure diagram>] in the document generation rule 130. A diagram held by a certain "sw structure diagram" is output. Here, <sw structure/sw structure diagram> indicates a path from the root element "sw structure" to the "sw structure diagram".

Furthermore, the document generation unit 103 outputs the character string described in the document generation rule 130 to the document 140 as it is. For example, the document generation unit 103 outputs the character string “2.class definition” to the corresponding area of the document 140 as it is for the part described as “2.class definition” in the document generation rule 130 .

As described above, the document generator 103 can generate the document 140 shown in FIG.
A document generated by the document generation unit 103 is sent to the output unit 104 .

The output unit 104 receives the document from the document generation unit 103 and outputs the document in a form visible to the user.
As an example, the output unit 104 displays a document. As an example, the output unit 104 outputs the document by printing it on a medium.

The input unit 105 receives an input of a document position, which is the position of the document output by the output unit 104, and a review indication indicating the indication of the document position. The input review indication is given to the indication target element search unit 106 and the system model correction unit 107 .

FIG. 6 is a schematic diagram showing an example of a review indication received by the input unit 105. As shown in FIG.
As shown in FIG. 6, review indications 150 include a document location and an indication for that document location.
In the example of FIG. 6, "Section 2.2" is included as the document location, and "the description aaa of get is an error of bbb" is included as an indication at this location.
Also, "Fig. 2-1" is included as the document location, and "ccc appearing in the figure is unnecessary" is included as the content of the indication at this location.

The input unit 105 may receive an input of a review indication from the user via a mouse or a keyboard, or may receive an input of a review indication by speech recognition via a microphone.
Furthermore, if there is a system that analyzes documents and automatically outputs review indications, the input unit 105 may receive input of review indications from that system.

The indication target element search unit 106 uses the system model stored in the system model storage unit 101 and the document generated by the document generation unit 103 to provide a system corresponding to the indication in the review indication received by the input unit 105. Search for an indicated element that is an element in the model.

FIG. 7 is a block diagram schematically showing the configuration of the pointed-out element searching unit 106 according to the first embodiment.
The indication target element search unit 106 includes an indication target element candidate identification unit 160 and a character search unit 164 .

The indication target element candidate identification unit 160 uses the system model and the document to identify an indication target element candidate, which is an element candidate in the system model, corresponding to the point pointed out in the review indication.

The indication target element candidate identification unit 160 includes an output element identification unit 161 , an association DB 162 and a position element identification unit 163 .

The output element identifying unit 161 identifies a plurality of predetermined specific ranges from the document, and identifies the correspondence between the elements output to each of the plurality of specific ranges and the elements in the system model. The specific range is, for example, a range within the document that is delimited by each item number such as Chapter 1 or each page number such as 5p. Note that the specific range may be determined in advance.

The output element specifying unit 161 refers to the document to output the elements output to each of a plurality of specific ranges, which are a plurality of predetermined ranges, among the plurality of elements included in the system model. Identifies as an element. Then, the output element specifying unit 161 generates association information that associates each of the plurality of specific ranges with the output element output to each of the plurality of specific ranges.

For example, the output element identifying unit 161 analyzes character strings within a specific range of the document and identifies elements in the system model with high correlation as output elements that are elements corresponding to the specific range. For example, if the character string within the specific range matches any of the metadata of the element in the system model, the output element identifying unit 161 determines that the character string is highly correlated with the element. good.

Specifically, in the case of the system model 110 shown in FIG. 2 and the document 140 shown in FIG. and "get", it is estimated that the elements of <sw structure/classA> and <sw structure/classA/get> of the system model 110 are output to item number 2.2 . Therefore, the output element identifying unit 161 identifies <sw structure/classA> and <sw structure/classA/get> as elements corresponding to item number 2.2. It should be noted that the element is specified so that the element position, which is the position of the element in the system model, can be identified. Here, the element position is identified by the path from the root element. In other words, the association information should associate each of the plurality of specific ranges with the element position of the output element output to each of the plurality of specific ranges.

Then, the output element specifying unit 161 stores, in the association DB 162, association information that associates the specific range indicating the specific range of the document with the element corresponding to the specific range.

The association DB 162 is an association information storage unit that stores association information from the output element identification unit 161.

FIG. 8 is a schematic diagram showing an example of association information stored in the association DB 162. As shown in FIG.
As illustrated in FIG. 8 , the association information 170 indicates a specific range 171 and elements 172 .
In FIG. 8, the specific range 171 indicates chapters and sections of the document, but the first embodiment is not limited to such examples. For example, the document page number may be used as the specific range 171 .

The positional element identifying unit 163 refers to the association information stored in the association DB 162 to identify output elements included in a specific range corresponding to the document position among a plurality of specific ranges as indication target element candidates. do.

For example, the positional element identification unit 163 identifies elements associated with a specific range corresponding to the document position included in the review indication as indication target element candidates. The specified indication target element candidate is provided to the character search unit 164 together with the corresponding review indication.

Specifically, in the association information 170 shown in FIG. From the line 173 corresponding to "Section", the element included in the line 173 is identified as a pointing target element candidate. The identified pointing target element candidates are as shown in FIG.

It should be noted that, for example, when the document position is the page number of the document, the positional element identifying unit 163 identifies from the association DB 162 the indication target element candidate corresponding to the page number.

Further, for example, when the document position is not included in the association information stored in the association DB 162, the positional element identifying unit 163 identifies all of the elements included in the association information as indication target element candidates. good too. Specifically, when the document position is a page number, but the association information does not specify an element in association with the page number, the position element identification unit 163 identifies all the elements included in the association information as Identify as an indication target element candidate. As a result, since the elements included in the association information are only the elements output to the document, the elements that are not output to the document can be excluded from the indication target element candidates.

The character search unit 164 identifies an indication target element, which is an element pointed out in the review indication, from the indication target element candidates by comparing the content of the indication in the review indication and the content of the indication target element candidate. It functions as an indication target element specifying unit.

For example, the character search unit 164 searches for a character string of metadata included in an indication target element candidate corresponding to the review indication based on the character string indicated in the review indication, and searches for an element corresponding to the indicated content. Identify the pointed out element that is The specified pointed out element is provided to the system model correction unit 107 together with the corresponding review pointed out.

Specifically, if the candidate element to be pointed out is as shown in FIG. Metadata of elements that are indication target element candidates in the column is searched, and an element of <sw structure/get-element name> with a high correlation is specified as an indication target element. Here, when the specified character string and the character string included in the metadata of the element match, it is determined that the correlation is high. In other words, the character search unit 164 identifies, as an indication target element, an indication target element candidate including a character string that matches the character string indicating the content of indication. The specified pointing element is as shown in FIG. 10, for example.

Note that the character search unit 164 may specify all indication target element candidates as indication target elements when there is no element highly correlated with the character string pointed out in the review indication in the character string search. This can reduce erroneous exclusion of elements that should not be excluded depending on the performance of the character search section 164 . For example, if the review indication includes a description of class A, the correlation between the element "class A" and the review indication "class A" is weak in the character string search. At this time, if there is no element highly correlated with the review indication “class A”, all indication target element candidates may be specified as indication target elements. This can reduce erroneous exclusion of the element "classA", which is considered to be the element that the reviewer originally wanted to point out.

Furthermore, in the character string search, if there are multiple elements that are highly correlated with the pointed out character string, the character search unit 164 may specify those multiple elements as pointed out elements. Thereby, it is possible to deal with the case where the user points out a plurality of elements.

Returning to FIG. 1, the system model correction unit 107 corrects the indication target element in the system model based on the review indication. Specifically, the system model correction unit 107 corrects the indicated element according to the content of the indication when the content of the indication in the review indication is the correction of the system model. The corrected system model is stored in the post-correction system model storage unit 108 .

For example, if the pointed-out element is <sw structure/get-element name> and the pointed-out in the review pointing out includes the information "change get to getSize", the system model correction unit 107 adds <sw structure Modify the element name of /get-element name> from "get" to "getSize".
In this case, it is desirable that a description method for correction is predetermined so that the system model correction unit 107 can clearly specify the content of the indication in the review indication.

Further, if the content of the indication in the review indication is not correction but, for example, a comment, the system model correction unit 107 does not correct the system model, and sends the indication target element and the indication to the user via the output unit 104. may be presented.
In order to reliably perform the above processing, it is desirable for the user to input whether the content of the indication is a "correction" or a "comment" when making a review indication. In this case, the review indication received by the input unit 105 includes information indicating "correction" or "comment."

Note that, for example, when a plurality of indication target elements correspond to a review indication, or when the description method of the review indication is not a predetermined description method, etc., when the correction method cannot be clearly determined, the system model correction unit 107 may present the pointed-out element and pointed out to the user via the output unit 104 and ask for the user's judgment via the input unit 105 .

In addition, the system model correction unit 107 presents correction details of the system model to the user via the output unit 104 before correcting the system model based on the review indication, and the correction is requested from the user via the input unit 105. Modifications may be made only with permission. This eliminates inadvertent modification of the system model due to inappropriate review indications.

The corrected system model storage unit 108 stores the corrected system model, which is the system model corrected by the system model correction unit 107 .

The development support device 100 described above can be realized by, for example, the computer 10 shown in FIG.
Computer 10 includes auxiliary storage device 11 , memory 12 , processor 13 , display device 14 , input device 15 and connection I/F 16 .

The auxiliary storage device 11 stores programs and data necessary for processing of the computer 10 . The auxiliary storage device 11 is, for example, an HDD (Hard Disk Drive) or an SSD (Solid State Drive).
The memory 12 is a non-volatile or volatile memory that temporarily stores programs and data and provides a work area for the processor 13 to process.
The processor 13 is a CPU (Central Processing Unit) or the like that performs various processes by reading a program stored in the auxiliary storage device 11 into the memory 12 and executing the program.

The program described above may be provided through a network, or may be provided after being recorded on a recording medium. That is, such programs may be provided as program products, for example.

The display device 14 is a display or the like that displays various screen images.
The input device 15 receives input of operations from the user. The input device 15 is, for example, a mouse or keyboard.
A connection I/F 16 is an interface for connecting external equipment to the computer 10 . For example, a document can be printed by connecting a printer (not shown) to the computer 10 .

Specifically, the system model storage unit 101, the document generation rule storage unit 102, and the corrected system model storage unit 108 of the development support device 100 can be realized by the auxiliary storage device 11 or the memory 12.

The document generation unit 103, the pointed-out element search unit 106, and the system model correction unit 107 are realized by the processor 13 reading a program stored in the auxiliary storage device 11 into the memory 12 and executing the program. can be done.

The output unit 104 can be realized by the display device 14 or the connection I/F 16 and a printer (not shown) connected to the connection I/F 16 .
The input unit 105 can be implemented by the input device 15 .

In the first embodiment described above, the output element specifying unit 161 of the indication target element searching unit 106 analyzes the character strings within the specified range of the document, and identifies the elements in the system model that have a high correlation within the specified range. is specified as an element corresponding to , the first embodiment is not limited to such an example.

For example, the output element identification unit 161 may analyze the document generation rule and identify elements in the system model with high correlation as elements corresponding to the specific range.
Specifically, when the system model 110 shown in FIG. 2 and the document generation rule 130 shown in FIG. contains the description "[insert <sw structure>note]", it is determined that the <sw structure> element of the system model 110 is output to item number 2.1. As a result, the output element identifying unit 161 identifies <sw structure> as an element corresponding to item number 2.1.

Also, for example, the output element identifying unit 161 determines that since item number section 2.2 of the document 140 includes the description "[<sw structure/classA> insert element names for the following operations one line at a time]", Search the system model 110 and determine that the <sw structure/classA/get> or <sw structure/classA/set> element is output in item number 2.2. As a result, the output element identifying unit 161 identifies <sw structure/classA/get> and <sw structure/classA/set> as elements corresponding to item number 2.2.

Further, for example, although not shown, if the document generation rule defines that the item numbers are assigned in order from the top along the tree structure of the system model and output, the output element specifying unit 161 Based on the tree structure of , specify the correspondence between the item number and the element. Specifically, in the tree structure of the system model, when there are A element, B element and C element as child elements of a node, the output element specifying unit 161 selects the A element for Chapter 1 and the B element for Chapter 2 of the document. It is judged that the C element is output in Chapter 3. As a result, the output element identifying unit 161 identifies the A element as the element corresponding to the item number of Chapter 1, identifies the B element as the element corresponding to the item number of Chapter 2, and identifies the B element as the element corresponding to the item number of Chapter 3. Specify the C element as the element.

As described above, by using the document generation rules, it is possible to identify the correspondence with higher accuracy than the document.
