Description

Design support device

The present invention relates to a design support apparatus for supporting a designer who performs product design, and in particular, in terms of prevention of confidential information leakage and export control when providing a document file created by product design or the like to another country or organization. The present invention relates to a design support apparatus that supports determination of availability.

Conventionally, export control efficiency is improved by utilizing the stored non-determination information as a technology that enables determination of availability while suppressing increase in man-hours even in situations where it is difficult for designers to determine availability. There is a thing to make it (for example, refer to patent documents 1).

JP, 2005-63119, A

In recent years, global development of product design has become widespread in the manufacturing industry. In the global development of product design, for example, data of standard machines designed by the Japanese design department and design documents are sent to the overseas design department, and based on this, customized design is performed in the overseas design department. Here, when sending a design document designed in Japan to an overseas design department, first, from the viewpoint of export control, it is judged whether or not the target document can be provided to the destination country, and then the confidential From the point of view of information leakage, it is necessary to determine a division that can be disclosed and a division according to the position of the viewer in the destination organization. With regard to export control, for example, regulations have been enacted such that information on parts leading to the development of nuclear weapons can not be exported to specific countries, and it is necessary to determine whether the contents of the target document fall under this law. is there. With regard to leakage of confidential information, for example, market disclosure materials such as product catalogs can be disclosed to all employees, documents including design know-how can be disclosed to all members of the design department and more than the head of the production department, design basis It is necessary to judge the classification of the document according to the internal rules, such as the document that can not be disclosed to all employees. However, because it is difficult to set a clear standard, it is difficult to set a clear standard for determining whether the content of the target document corresponds to the content regulated by the law or whether the content of the document corresponds to know-how. It is difficult for a shallow designer, and for example, it is necessary to refer to a case determined in the past, or to ask other veteran designers for work, which increases the number of man-hours.

For such problems, Patent Document 1 describes a system, method, program, and recording medium for improving the efficiency of export control by utilizing the stored non-determination information.

In the system, method, program and recording medium described in Patent Document 1, information such as product name, model, and manufacturer's name is stored for products for which export control was performed in the past, and export control is newly performed. The efficiency of export control can be improved by comparing the values of the structured information and presenting data of similar cases to the user. However, in the case where the subject of export control is a document, it is necessary to determine from the contents of the document whether export is possible, so the system described in Patent Document 1 can not determine whether it is similar. In addition to the determination of the contents of a document, it is also necessary to determine several stages of the release classification in accordance with the department of the organization to be disclosed and the position system of the viewer. The system described in can not support this determination.

The present invention has been made in view of the above-mentioned problems, and even an inexperienced designer can judge exportability or disclosure category in a short time, thereby making the design work highly efficient. It is an object of the present invention to provide a design support apparatus that can be integrated.

Hereinafter, embodiments of the present invention will be described in detail as each example with reference to the drawings. In the following description, "database" will be abbreviated as "DB" as appropriate.

Hereinafter, Example 1, which is the first embodiment of the present invention, will be described. In the present embodiment, a document for which a publication category has been set in the past is input from the past document DB, the similarity to the input determination target document is calculated, the publication category candidate value of the document is calculated, and presented to the user. An example of a design support apparatus will be described.

FIG. 1 shows an example of a system configuration diagram of this embodiment. In the system configuration diagram of this embodiment, at the time of document open classification determination, data is input and an input / output device 101 including a keyboard, a mouse, a display, etc. for displaying on a screen, and past design documents are registered. A past document DB 102, a past document input unit 103 for acquiring a past document from the past document DB, a determination target document 104, a determination target document input unit 105, and calculation of similarity between the past document and the determination target document The public category candidate value calculation unit 107 which calculates candidate values of the public category of the determination target document from the similarity calculation section 106, the public category set to the similarity and the past document, and the calculated public category candidate values The disclosure category setting unit 1 sets the disclosure category input by the user in the document disclosure category DB 109 with reference to the disclosure category candidate value display unit 108 and the disclosure category candidate display to be displayed. It is equipped with a 0. In this embodiment, determination of the disclosure category will be described as an example. However, when determining whether or not export is possible, the disclosure category candidate value calculation unit 107, the disclosure category candidate value display unit 108, the document disclosure category DB 109, the publication category The setting unit 110 serves as an exportability candidate value calculation unit, an exportability candidate value display unit, a document exportability DB, and an exportability setting unit.

First, the publication classification of the design document will be described with reference to FIG. A design document is a document that a designer refers to and produces in product design, and includes, for example, a product catalog, a design standard, a design specification, an analysis report, a past defect report, and the like. In the publication category of the design document, a reading restriction is set in a tabular format with respect to attributes such as a department or a position system of a reader, “o” indicates browsable, and “x” indicates browsability. In the example shown in FIG. 2, the target document file can be viewed by department A, as the department manager, as the department manager, and as the department manager, part B as the department manager, as the department manager as the department B. Here, in the example of FIG. 2, the number of attributes is two, that is, department and post, but it may be one or three or more. Moreover, when a country or a nationality is used as an attribute, it can be used for the determination of the propriety of export control. It is assumed that such a publication division is already set in the document registered in the past document DB 102, and the apparatus supports the work of setting the publication classification for a new document.

Hereinafter, the operation procedure of the present apparatus will be described.

In the present apparatus, first, the similarity between the document registered in the input past document DB and the document to be judged is calculated. The similarity calculation method uses, for example, the tf-idf (Term Frequency-Inverse Document Frequency) method. An example of the calculation processing flow of similarity using the tf-idf method will be described with reference to FIG. First, morphological analysis processing 303 is performed on the past document 301 and the determination target document 302, respectively. Morphological analysis is a process of dividing Japanese sentences into meaningful words. However, since English sentences and the like are divided into words from the beginning, processing of morphological analysis is not necessary. Next, tf-idf is calculated for each of the decomposed words. The tf-idf is calculated as follows based on two indices of tf (frequency of appearance of words) and idf (reverse document frequency).
tf-idf = log (tf + 1) · log (idf) (1)
idf = k / df (2)
Here, tf is the number of occurrences of a word, k is the total number of documents stored in the DB, and df is the number of documents including a word. The higher the number of words contained in a document, the higher the value of the word in tf-idf, and the lower the number of documents contained in other documents. As a result, the word that characterizes the document has a higher value, and the value of tf-idf can be used as the importance of the word. Next, tf-idf of words included in each document is used to calculate the similarity between the documents. There are several methods for calculating the degree of similarity. For example, it can be obtained by expressing the tf-idf of the words contained in a document as a feature vector and calculating the inner product of the vectors of two documents as follows: .
Past document feature vector D1 = (tf-idf1 ₁ , tf-idf1 ₂ , ..., tf-idf1 _n ) (3)
Feature vector D2 of the judgment document = (tf-idf2 ₁ , tf-idf2 ₂ , ..., tf-idf2 _n ) (4)
Similarity Sim (D1, D2) = D1 · D2 (5)
The calculation of the degree of similarity by the above processing is performed between all the documents registered in the past document and the determination target document.

A specific example will be described with reference to FIG. First, morphological analysis is performed on the sentences included in the past document 401 and the determination target document 402. The sentences subjected to morphological analysis are divided into words as 403 and 404. Next, tf-idf calculation is performed on the decomposed words. The results of the tf-idf calculations are represented as 405, 406, for example, characterizing documents such as product names, part names, technical terms, etc., such as "inverters" "fans" "cooling" Word value is higher. Finally, the similarity 407 between documents is calculated by calculating the inner product of feature vectors obtained by vectorizing these values.

Next, the flow of processing for calculating the disclosure category candidate value of the determination target document using the calculated document similarity will be described with reference to FIG. The calculation 503 of the disclosure category candidate value is performed using the degree of similarity 501 with the determination target document and the disclosure category 502 of the past document. There are several methods for calculating the public category candidate value, but here, the calculation method using weighted average by similarity is described. The publication category candidate value is calculated by weighting and averaging document similarity with “O” as +1.0 and “x” as −1.0 in FIG. 2 of the publication category of the past document.

A specific example will be described with reference to FIG. For the past document_1, the past document_2, and the past document_3 registered in the past document DB, publication classifications are set as 601, 602, and 603, respectively, and these past documents and the determination target document It is assumed that the similarity is calculated as 604. On the other hand, a weighted average is calculated with the degree of similarity to the document to be judged for each element in the table, with ○ being +1.0 and x being −1.0. For example, in FIG. 6, the disclosure category candidate value of "part A-responsible" is calculated as follows.
Public category candidate value (part A-responsible)
= {(1.0) * 0.15 + (-1.0) * 0.22 + (-1.0) * 0.63} / (0.15 + 0.22 + 0.63) = -0.70 (6)
Thus, as indicated at 605, candidate values for the public category are calculated for each attribute. The user may refer to the judgment in reference to the value such that the item having a high value is likely to be open for the document to be judged and the item having a low value is likely to be not open. it can. Here, the candidate value is calculated by weighting calculation based on the degree of similarity with all past documents, but in other cases, for example, the degree of similarity is calculated using only past documents having a certain degree of similarity or more. A method of calculating a weighted average of, a method of presenting a publication category of a document with the highest degree of similarity, or the like may be used.

A flow of setting a disclosure category candidate by the user will be described using the present apparatus. FIG. 7 shows an example of an execution screen of open category candidate value calculation. First, the user selects the document to be judged in the input box 701 from the input or reference button 702, and similarly selects the past document DB in the input box 703 from the input or reference button 704. Here, it is possible to move to the next screen with the execute button 705 and to end the data input screen with the cancel button 706. Next, the user designates an attribute to be determined on the attribute designation screen shown in FIG. From the attributes displayed in the pull-down menu for the attribute 801, an attribute to be determined is selected. Here, "Department", "Department", and "Country" are selected as attributes. Next, with the content setting button 804, the content of the selected attribute is set on the attribute content specification screen shown in FIG. Here, the procedure for setting the contents of “department” will be described. In the attribute content designation screen, an attribute 902 to be determined is selected from the pull-down for the attribute to be set as shown in 901. After setting, if it is determined by the execute button 903 or is canceled by the cancel button 904, the screen returns to the attribute designation screen of FIG. After setting the attribute content, when the execute button 802 is executed on the attribute designation screen, the disclosure category candidate value of the determination document is calculated, and the disclosure category candidate value display screen is presented to the user as shown in FIG. In the disclosure category candidate value display screen, first, the setting of the attribute to be displayed is performed. For the attribute 1001 for which the disclosure category candidate value has been calculated, one of “column”, “row”, and “fixed” is designated in the display setting column 1002. Here, the attribute specifying "column" and "row" is set in the column 1004 of the disclosure category candidate value, the row 1005, and the column 1007 and the row 1008 of the disclosure category specification. Here, for the attribute for which “fixed” is specified, a value to be displayed is selected in the attribute value column 1003. In the example of FIG. 10, the disclosure category candidate value for each department and job system for country Z is displayed at 1006. As an initial value, for example, "○" is input in the field where the value of the disclosure category candidate value is 0 or more, and "×" is input in the field smaller than 0 as the initial value in the disclosure category specification field 1009. The user corrects this initial value as necessary, referring to the disclosure category candidate value. The modified release category is stored in the document release category DB at an execution button 1010.

As described above, according to the first embodiment of the present invention, the similarity between the past design document and the determination target document is calculated, and the weighted average of the public categories for multi-dimensional attributes registered in the past design document is calculated. Thus, by calculating the disclosure category candidate value of the determination target document and presenting it to the user, even an inexperienced designer can determine whether or not the export is possible or disclosure category in a short time. Design can be made more efficient.

Hereinafter, Example 2 which is a second embodiment of the present invention will be described. In the present embodiment, an example of a design support apparatus will be described, which calculates the disclosure category candidate of the document to be determined using the disclosure category of the keyword designated in advance by the user.

In the present embodiment, the release classification shown in FIG. 2 is set in advance as a keyword instead of the past document, and the release classification candidate of the determination target document is calculated using this.

FIG. 11 shows an example of a system configuration diagram of the determination of the disclosure classification using a keyword. In the system configuration diagram of this embodiment, an input / output device 1101 including a keyboard, a mouse, a display, etc. for inputting data and displaying it on a screen at the time of document open classification determination is registered with a keyword open classification. Keyword DB 1102, a past document input unit 1103 for inputting a past document, a judgment object document input unit 1105 for inputting a judgment object document 1104, and a publication classification candidate for the judgment object document from the publication classification of the keyword and the judgment object document And a public category candidate display unit 1107 for displaying the calculated public category candidate.

A specific example will be described with reference to FIG. Here, there are two attributes to be determined, department and job. First, the user sets in advance the disclosure classification for each keyword as 1201 to 1203. Then, after morphological analysis is performed on the determination target document, it is determined whether each keyword is included in the document, and even if there is only one in the document, the disclosure category of the attribute including the keyword “x” is It is determined as "x". Thereby, when the content which can not be disclosed is included as in 1204, it is possible to determine that the corresponding attribute is "x". The user refers to this public category candidate as an initial value, and corrects it as necessary. Here, although one or more “x” is determined to be “x” when it exists, for example, it is also determined to be “x” when the number “x” is greater than or equal to a designated value. A method or the like can be used.

The third embodiment which is the third embodiment of the present invention will be described below. In the present embodiment, an example of an apparatus that controls browsing in accordance with a set publication category of a document in response to a browsing request from a browser will be described.

FIG. 13 shows an example of the system configuration of the document reading control apparatus. The system configuration of this embodiment is based on an input / output device 1301 including a keyboard, a mouse, a display, etc. for displaying data on a screen when a viewer requests browsing of a document and browsing the document, and viewer attributes A browsing information input unit 1304 for inputting 1302 and a browsing document name 1303, a document disclosure category DB 1305 in which a document disclosure category is registered, a document disclosure category DB input unit 1306 for entering a document disclosure category DB, and a browsing request document And a browsed document presentation unit 1309 which presents a document from the document DB 1308 when the browse request document is browseable.

When a reader requests a document that he / she wants to browse from this device, this device refers to the publication classification of the browsing request document registered in the document publication classification DB for the reader attribute such as the department or job classification to which the reader belongs If it is not possible, the browsing is refused, and if it is publicly available, the browsing request document is presented to the viewer. In this way, document browsing control can be performed according to the attribute of the browser. Note that the document is encrypted and stored in a server or the like, and the browsing document presentation unit 1309 can increase the security against information leakage by deciphering and presenting the document when presenting the document to the viewer.
