  Also, keyword extraction means 107 that acquires keywords from a document that is called from the design information database 103 and displayed or executed on the display, and design information that is displayed to the user based on the keywords extracted by the keyword extraction means 107 Classification category determining means 110 for determining the classification category and the display order thereof, classification category priority determining means 114, and the order in which the classification category design information determined by the classification category determining means 110 is determined by the classification category priority determining means 114 And a classification result display means 111 for displaying a classification category having a high priority on the top.

  The information search system further creates a document displayed or executed on the display as a product based on the reference information in the design information database 103 read by the business support means 105, the design information such as the examination document, and the accident information. A document creation source business process discrimination means 108 for discriminating the original business procedure. The classification category priority determining unit 114 obtains the number of appearances of the task described in the task list 112 and its related words in the document displayed or executed on the display and the document creation source business process determination unit 108. The priority of the classification category to be displayed to the user is determined according to the distance between the determined business procedure and the business procedure under consideration.

The information search system also includes an assignment list 112 describing assignments and related words, assignment list editing means 113 for editing the assignment list 112, and design information stored in the design information database 103. A classification unit 109 that classifies the tasks according to the categories described in Table 112, and a classification result database 104 that stores the classification results of the classification unit 109 are provided.
[Business process template]
The configuration of the business process template is shown in FIG. The business process template represents a series of business information as a set of a plurality of ordered business processes, and each business process can be expressed by being divided into more detailed business processes. In other words, the business process template represents business information as a set of business processes having a hierarchical structure, and the business process is composed of business procedures one by one. In FIG. 2, the business process template is composed of the following three types of data.

  The first is common data 201, which is composed of template ID, template name, and project name data. The template ID is an ID assigned by the system when the user creates a template. This template ID shall not overlap with other template IDs.

  The second is unit business process data 202, which is business process ID, business process name, comment, person in charge, deadline, registration work time, start date, end date, achievement rate, actual work time, actual start date, actual end. It consists of date, preceding process, product title and storage address in the design information database, reference material title and storage address data in the design information database.

  The business process ID is an ID assigned by the system when a business process is defined, and does not overlap with other business process IDs. The business process name is a name given to the business process when the user defines the business process. The registered work time, start date, and end date are the work time, start date, and end date planned before the start of the project, and the actual work time, start date, and end date are the actual work. These are the time, actual start date, and actual end date. The preceding process means a business process that must be completed before the business process is executed, and the business process is examined using a product in the preceding process. The business process template describes the business process ID of the preceding process.

  The third is the process order / hierarchical data 203, and the order in which the business processes are executed and the parent-child relationship between the business processes are defined for the unit business process data 202 described above. In the example of FIG. 2, business processes with business process IDs 1 and 5 are defined as the highest business process in the process order / hierarchical data 203. Further, a business process with a business process ID of 2 and a business process with a business process ID of 3 are defined in a lower hierarchy of the business process with a business process ID of 1.

  Next, when the business process template is read into the business support means 105, the business processes are displayed in a hierarchical manner on the display of the input / output device 101 as shown in FIG. FIG. 3 shows an example in which the business process template of the “A model development design” project is executed. “A model development design” is displayed at the highest level, and “product planning”, “concept design”, “detailed design”, “prototype / test”, and “drawing” are displayed at the lower level. Further, further detailed business processes are displayed in the lower hierarchy.

  Further, when a process display button (not shown) is pressed to switch to an arrow display mode and the user selects an arbitrary business process (displayed by a circle), the relationship between the preceding and succeeding business processes is displayed by an arrow. The business procedure in the present invention refers to the order of business related in the relationship between the preceding and succeeding business processes.

  The left-pointing arrow indicates that the business process “Create thermal examination result report” 302 is a preceding process of the business process “Create strength examination result report” 303 selected by the user. That is, in the “strength study result report creation”, since the shape satisfying the design condition of the strength is examined within the range satisfying the heat design condition in the “thermal study result report creation” 302 of the upstream process, "Creation of heat examination result report" is displayed.

  Also, the business process “research mechanism” 304 indicated by the right arrow represents a process subsequent to the selected business process “create strength review result report” 303. That is, the subsequent process means a business process that must be started after the business process is executed. These preceding / following processes are displayed using the preceding process information in the unit work process data 202 of the work process template data.

FIG. 4 shows the entire screen displayed by the processing of the business support means 105. In the left frame is the business process display area 401 shown in FIG. When the “Output” tab 402 in the right frame is selected, a list of deliverables registered for each business process is displayed. In the example of FIG. 4, the “thermal examination result report” is displayed on the display in the business process of “creation of thermal examination result report”. In addition, when a “Reference” tab 403 is selected, a list of reference materials associated with each business process is displayed. By selecting the reference material list, the deliverables and reference materials stored in the design information database can be referred to. Reference numeral 404 denotes a process display button.
[Automatic classification of design information]
In this system, a problem that the user is considering is identified from design information such as a document currently displayed or executed on a display periodically, and a design stored in the design information database 103 based on the problem is identified. Automatically present the results of classifying information. The processing at that time will be described below with reference to the flowcharts of FIGS.

  In the system of the present invention, as shown in FIG. 5, the keyword extraction unit 107 shown in FIG. 1 periodically reads a document being activated such as a getObject function provided by VBA (Visual Basic (registered trademark) for Application). The number N of active documents, the title and storage address of each document are acquired using a function for acquiring information, and an N-by-2 array as shown in FIG. The document title 801 and the storage destination address 802 are stored (S501). Subsequently, the text output program is executed with the storage destination address stored in the array in the memory as input, the text information is acquired from the active document, and is output as a text file (S502).

  The keyword extraction means 107 executes the morphological analysis program with this text file as input, and decomposes the text information into words (S503). Of the decomposed words, only nouns are extracted and stored in the memory as keywords (S504). For example, in the case of text information “consider the strength of a part”, the text information is decomposed into “part”, “no”, “strength”, “no”, “examine”. When a noun word is extracted from these, “component” and “strength” are acquired as keywords.

  Next, the classification category determining unit 110 matches the acquired keyword with the related word of each task described in the task list 112, and counts the number of appearances Xn of the related word in the document for each task (S505). In the assignment list 112, as shown in FIG. 9, related words 903 are described in association with each assignment 902. Reference numeral 901 denotes an assignment number.

  A task with Xn of 1 or more means a task in a business process currently being executed. For example, when design information as shown in FIG. 10 is displayed or executed on the display, keywords such as “strength”, “stress”, and “proof strength” are extracted. When these keywords are compared with the problem list shown in FIG. 9, the related words of “strength” 907 match, and “strength” becomes a problem in the business process currently being executed.

  Next, the business process template data read by the business support unit 105 is acquired by the document creation source business process determination unit 108 as shown in the flowchart of FIG. The selected business process is acquired (S602). Next, it is compared whether the title and reference material of the product of the unit business process data of the acquired business process template data match the title of the active document stored in the array in the memory (S603). If they match, a business process name is acquired that matches the title and reference material of the deliverable of the unit business process data of the business process template data and the title of the acquired document (S604).

The business process ID of the preceding process of the unit business process data of the business process template data is traced from the business process selected by the business support means, and the number of procedures Yn to the acquired business process is acquired (S605). If the title of the deliverable of the unit business process data in the business process template data does not match the title of the active document, Yn = 0 is set. Xn and Yn are obtained by the number N of documents displayed.
[Degree of relevance P]
Subsequently, as shown in the flowchart of FIG. 7, the classification category priority order determination unit 114 calculates the degree of association P between the task and the business process currently being executed (S701). The degree of relevance P is obtained by equation (1). This formula has a higher degree of relevance P for the business process that is currently being executed, as it contains more related words and the related words are included in the product of the business process that is closer to the business process that is currently being executed. Means.
Relevance P = ΣXn × Zn (1)
Xn: The number of occurrences of the related word of the task in the document displayed on the display Zn: The degree of association between the document displayed on the display and the business process currently being executed Yn: The business process in which the displayed document is registered When,
Relevance of the currently executing business process M: Total number of procedures defined in the template Zn = M / (Yn + 1): When the title of the active document matches the title of the business process product or reference material Zn = 1: When the title of the active document does not match the title of the business process product or reference material For example, a “thermal study result report” that describes the study results on the temperature distribution in the product is displayed or executed on the display. 4, it can be seen from the business process template data that the business process in which this design information is registered is “thermal study result report creation” as in the example of FIG. 4. When the business process currently under consideration is “strength study result report creation”, as shown in FIG. 3, “thermal study result report creation” is one upstream of “strength study result report creation”. Since it is a business process, Yn is 1 and Zn is M / 2.

  Further, when “strength study reference material” as shown in FIG. 10 is simultaneously displayed or executed on the display, “strength” is extracted as a problem. If this “Strength Study Reference Material” is registered as a reference material for the currently executing business process “Strength Review Result Report”, the business process in which the displayed document is registered, The number of procedures Yn with the business process being executed is 0, and Zn = M. Therefore, when Xn is the same, “strength” is more relevant than “heat”.

  Subsequently, the design information stored in the design information database 103 is classified in advance according to the problems described in the problem list 112, and the results classified according to the problems are highly related as shown in FIG. Present in order (S702). FIG. 11 is a display example of results classified by “strength” 1102 and “heat” 1106. On the right side of each category, the relevance degree obtained by the equation (1) is displayed, and “strength” 1102 which is a task having a high relevance degree of 67 is displayed at the top.

Next, the title 1103 of the design information classified into the task is displayed in the lower hierarchy of the classification, and the design information 1104 is displayed by selecting this title on the screen.
[Relationship Q about design information]
Next, with respect to the design information classified for each problem, the degree of relevance Q with the business process currently being executed selected by the business support means 105 is obtained and displayed in descending order. The degree of relevance Q is displayed on.

  In order to obtain the relevance level Q, first, a document vector having the appearance frequency of the included word as a component is generated for the business process name and the document. Here, assuming that the document vector generated from the business process name is a vector A and the document vector generated from the document is a vector B, the relevance Q related to the design information is obtained by Expression (2). Information having a higher degree of relevance is obtained when the value obtained by the equation (2) is closer to 100. When the document vector of the business process name is generated, the comment information of the unit business process data 202 of the business process template data may be added. Furthermore, each component of the document vector may be weighted according to the importance of the word.

  The document classification method for each problem will be described below. First, a plurality of representative design information classified into the category of the problem is associated with each problem described in the problem list 112 in advance. Subsequently, the degree of association between the design information to be classified and the representative design information associated with the category of each task is calculated by Expression (2). The design information to be classified is assigned to the document category including the top K items of the design information having a high degree of association. K is a number that can be arbitrarily designated by the system administrator.

This document classification method is only an example, and other methods may be used instead of the above method. Further, as shown in FIG. 11, the classification result by the problem is further classified by the product name / part name, and the product name / part name is acquired from the keyword included in the design information displayed or executed on the screen, You may display it focusing on the subject regarding the product and parts.
[Classification display for trade-offs]
In this system, in addition to presenting the results of classifying design information stored in the design information database based on the issues that the user is considering, issues that are trade-offs (reciprocal relationships) Categorize and present. As for a task that is a trade-off for a certain task, No assigned to each task is described in the trade-off relation column 904 of the task list in FIG. For example, since the issue No. that is a trade-off with respect to the strength 907 is 5 (906), the examination issue that is a trade-off is the weight reduction 905. With respect to the problem that is the trade-off obtained in this way, the classification result is displayed in the lower hierarchy of the intensity classification result, as indicated by 1105 in FIG.

  Conventionally, as shown in FIG. 12, a user inputs a search keyword into a search system (1201), performs a search, and from a search result (1202) ordered based only on the degree of relevance with the search keyword, a necessary result is obtained. I was looking for design information. On the other hand, in the system of the present invention, the classification category of the problem under consideration by the user is displayed together with the relevance of the business process being executed as shown in FIG. 11 without inputting the business process information. can do. Furthermore, the classified design information can be displayed in descending order of the relevance of the business process being executed, and the relevance can be displayed for each design information. As a result, the user can efficiently search for information related to the business process being executed without taking time and effort.

Furthermore, in the past, related information could not be obtained unless the search keyword was specified by the user, whereas in addition to issues that the user was considering, trades that the user was not aware of The classification result of the design information can be obtained even for the off-task.
[Business support method]
When the business process template data is read by the business support means 105 shown in FIG. 1, the user can proceed with the business without omission by performing the business according to the business process displayed in the business process display area 401 of FIG. Further, when a “Reference” tab 403 is selected, a list of reference materials associated with each business process is displayed. By selecting the reference material from the list, the reference material stored in the design information database 103 can be referred to. As a result, it is possible to efficiently carry out business while referring to reference materials associated with each business process.

  Further, the business support means 105 can register and manage deliverables such as design review reports and progress information for each business process. The registered deliverables are displayed as a list when the “Output” tab 402 in the right frame of FIG. 4 is selected.

  Figure 13 shows an example of product registration. When registering a deliverable, a business process is selected and a registration button 1301 is pressed. Here, on the displayed product registration screen 1302, a file to be a product stored on the personal computer is designated, a title is input, and a registration button 1303 is pressed, the product is registered. The registered product is stored in the design information database 103, and the title of the input result section and the storage destination address in the product design information database are written in the business process template.

As shown in FIG. 14, when the mouse cursor 1402 is moved over a specific business process, progress information is displayed on a progress display screen 1403. The displayed information includes a person in charge, work time, start date, end date, achievement rate, actual work time, actual start date, actual end date, and the like.
When registering progress information, a progress information registration screen 1403 is displayed for each business process.

15 and 16 show examples of registration of progress information. On the progress information registration screen 1503, the screen can be switched between a “general” tab 1501 and a “details” tab 1502. On the screen displayed by selecting the “General” tab 1501, information such as the achievement rate, the actual work time, the actual start date, the actual end date, and the like can be registered. On the screen displayed by selecting the “details” tab 1502, information such as a deadline, a reference work time, a reference start date, and a reference end date can be registered as shown in FIG.
[Edit business process template]
