*** Explanation of operation ***
With reference to FIGS. 1 to 7, the operation of the traceability management apparatus 200 according to the present embodiment will be described. The operation of the traceability management apparatus 200 corresponds to the traceability management method according to the present embodiment.

  In step S <b> 11 of FIG. 2, the traceability management apparatus 200 receives input of the document 301 and various settings from the user via the input device 203.

  Specifically, the traceability management unit 107 of the traceability management apparatus 200 receives an input of the document 301. In the present embodiment, a plurality of documents 301 are input from the user. The document 301 is not limited as long as it is subject to traceability management, but in the present embodiment, the document 301 is a product created in the development process of a product such as software.

  Further, the traceability management apparatus 200 accepts the valid / invalid setting of the notation fluctuation setting database 100 of FIG. At this time, when the old kanji in the notation fluctuation setting database 100 is validated, the traceability management apparatus 200 creates the new / old kanji correspondence database 102. Further, when the sending pseudonym in the notation fluctuation setting database 100 is validated, the traceability management apparatus 200 creates the sending pseudonym database 103.

  As shown in FIG. 3, in this embodiment, the notation fluctuation setting database 100 is a database that stores data indicating the type of notation fluctuation specified in advance as the notation fluctuation type.

  The traceability management apparatus 200 also accepts the setting of the excluded character string database 104 in FIG.

  As shown in FIG. 4, in this embodiment, the excluded character string database 104 is a database that stores data indicating a character string designated in advance as an excluded character string.

  The traceability management apparatus 200 further creates the traceability information database 106 shown in FIG. At this time, the user extracts a character string used for ensuring traceability from the document 301 and stores it in the traceability information 1 in the traceability information database 106. The ID is automatically assigned with a unique value. “ID” is an abbreviation for Identifier.

  As shown in FIG. 5, in the present embodiment, the traceability information database 106 is a database that stores data indicating, as traceability information, character strings searched in a plurality of documents 301 for traceability management of the documents 301. . The data stored in the traceability information database 106 is data indicating groups of character strings whose notations are different from each other due to the notation for each ID that is a unique identifier. When n is an integer of 2 or more, traceability information 1 to traceability information n in the traceability information database 106 constitute one group. Note that the number n of character strings belonging to one group may be an arbitrary number, or may be different depending on the group.

  In step S12 of FIG. 2, the notation fluctuation data creation unit 101 of the traceability management apparatus 200 acquires the character string indicated by the data stored in the traceability information database 106 as a third character string. The notation fluctuation data creation unit 101 creates a fourth character string by changing the notation of the third character string. At this time, the notation fluctuation data creation unit 101 creates a fourth character string from the third character string according to the type indicated by the data stored in the notation fluctuation setting database 100. Then, the notation fluctuation data creation unit 101 updates the data stored in the traceability information database 106 to data indicating the fourth character string in addition to the third character string.

  That is, the notation fluctuation data creation unit 101 acquires the data of the traceability information database 106 and updates the data of the traceability information database 106 according to the setting contents of the notation fluctuation setting database 100 for the traceability information 1 included in the acquired data. Do.

  As a specific example, in the data of ID = X in the traceability information database 106, the traceability information 1 stores a character string “port switch” in which “port” is full-width, and the full-width / half-width of the notation fluctuation setting database 100 and Assume that sending pseudonym is enabled. In this case, in the data of ID = X in the traceability information database 106, the notation fluctuation data creation unit 101 causes the characters such as “port switching”, “port switching”, and “port switching” in which “port” is half-width after the traceability information 2. A column is added.

  In step S13 of FIG. 2, the excluded character string data creation unit 105 of the traceability management apparatus 200 acquires the character string indicated by the data stored in the traceability information database 106 as the first character string. The excluded character string data creation unit 105 searches the first character string in the document 301 input to the traceability management unit 107, and if the number of appearances of the first character string is below the threshold, the first character string starts from the first character string. A second character string is created by excluding some character strings. At this time, the excluded character string data creation unit 105 creates a second character string by excluding the character string indicated by the data stored in the excluded character string database 104 from the first character string. Then, the excluded character string data creation unit 105 searches the document 301 input to the traceability management unit 107 for the second character string, and if the number of appearances of the second character string exceeds the threshold value, the traceability information database The data stored in 106 is updated to data indicating the second character string instead of the first character string. If the number of appearances of the first character string is greater than or equal to the threshold, the excluded character string data creation unit 105 does not update the data. Even if the number of appearances of the first character string is less than the threshold value, but the number of appearances of the second character string is less than the threshold value, the excluded character string data creation unit 105 does not update the data. However, in this case, the excluded character string data creation unit 105 creates another second character string by changing the character string excluded from the first character string, and the number of appearances of the other second character string sets a threshold value. If so, the data stored in the traceability information database 106 may be updated to data indicating the other second character string instead of the first character string.

  That is, the excluded character string data creation unit 105 acquires the document 301, the data of the traceability information database 106, and the data of the excluded character string database 104, and investigates the number of occurrences of the traceability information in the document 301. At this time, the number of appearances is added in ID units of the traceability information database 106. The excluded character string data creation unit 105 deletes the valid character string and particle in the excluded character string database 104 from the character string of the traceability information when the numerical value after the sum is below the specified threshold value, and again Investigate the number of occurrences. As a result of the investigation, when the number of appearances exceeds the threshold, the excluded character string data creation unit 105 updates the traceability information database 106 with the updated character string.

  As a specific example, in the data of ID = Y in the traceability information database 106, the character string “operation control command” is stored in the traceability information 1, and the character string “command” is stored in the excluded character string database 104. Suppose that In this case, if the character string “driving control command” does not appear above the threshold in the document 301, the excluded character string data creating unit 105 converts the particle “no” and the excluded character string from “driving control command”. The number of appearances is checked again with the character string “operation control” excluding “command”. As a result, if the number of appearances exceeds the threshold value, the traceability information 1 is updated to “operation control” by the excluded character string data creation unit 105 in the data of ID = Y in the traceability information database 106.

  In step S14 of FIG. 2, the traceability management unit 107 of the traceability management apparatus 200 extracts two or more documents 301 in which character strings belonging to the same group appear from the plurality of documents 301 input in step S11. Then, the traceability management unit 107 outputs data including an ID that is an identifier corresponding to the same group and information for identifying the extracted document 301 as the traceability data 108. The information for identifying the document 301 may be an arbitrary identifier, but in the present embodiment, is the name of the document 301.

  Specifically, the traceability management unit 107 acquires the document 301 and the data of the traceability information database 106, and when traceability information with the same ID is found from two or more documents 301, determines that the traceability is secured. To do. That is, if the IDs are the same, the traceability management unit 107 determines that a character string that is different between two or more documents 301 is a common character string. Then, the traceability management unit 107 creates the traceability data 108 of FIG. At this time, the same ID as the ID of the traceability information database 106 is stored as the ID of the traceability data 108. As the appearance position of the traceability data 108, the name of the document 301 where the traceability information appears and the position where the traceability information appears are stored.

  In step S15 of FIG. 2, the synonym synonym determination unit 109 of the traceability management apparatus 200 adds two or more documents 301 extracted by the traceability management unit 107 based on the traceability data 108 output by the traceability management unit 107. Parsing is performed for the meaning of the character strings belonging to the same group. When two or more character strings having different meanings are included in the same group, the same spelling synonym determination unit 109 corrects the data stored in the traceability information database 106.

  Specifically, the synonym synonym determination unit 109 acquires the document 301, the data of the traceability information database 106, and the traceability data 108, and parses the sentence including the traceability information that appears in the document 301. And identify the meaning of traceability information in the text. As a meaning identification method, lexical analysis of sentences including traceability information is performed for each of the upper document appearance position and the lower document appearance position of the traceability data 108 in FIG. 6, and a parse tree based on the traceability information is created. Can be used. The same spelling synonym determination unit 109 performs this operation on all sentences including traceability information with the same ID. After the implementation, the synonym synonym determination unit 109 calculates the similarity of all the parse trees with the same ID created in the upper document from the number of matches of the branches and leaves, and creates a group with a combination having a high similarity. Thereafter, the synonym pronoun determination unit 109 measures the similarity with the syntax tree created in the lower document for each group, links the group having the highest similarity with the lower document, and performs FIG. The traceability database 110 is created.

*** Explanation of the effect of the embodiment ***
In the present embodiment, since the traceability information stored in the traceability information database 106 is corrected as appropriate, it is easy to ensure traceability between documents.

  In the present embodiment, it is possible to improve the completeness and accuracy of traceability by updating the traceability information used for ensuring traceability between documents 301 created in each process at the time of product development.

Character strings that did not match in pattern matching can be matched. That is, even if there is a notation between the documents 301 created in each process at the time of product development, traceability can be secured without correction of the document 301, and omission of traceability can be reduced. Become. Furthermore, it is possible to define the type of notation fluctuation and specify the type of notation fluctuation that is handled as the same character string.

  In the present embodiment, the frequency at which traceability information appears in the document 301 is measured, and when the appearance frequency does not exceed the threshold, a specific character string that is a factor that inhibits character string matching is excluded from the traceability information. By performing the search again, the appearance rate of traceability information can be improved. That is, it is possible to automatically improve the accuracy of the traceability information created manually, and to reduce omission of traceability. Furthermore, it is possible to specify a character string to be excluded.

  Furthermore, in the present embodiment, syntactic analysis is performed on the document 301 including the character string that matches the traceability information, and the meaning of the traceability information is specified, so that the same-synonyms are distinguished, and different traceability information is obtained. By making the determination, it is possible to reduce erroneous traceability. As a result, the accuracy of traceability can be improved.

  As described above, according to the present embodiment, the correction of traceability information using the appearance frequency of traceability information and the correspondence to the notation fluctuation that could not be secured by the traceability management tool using pattern matching. It becomes possible to eliminate the omission of traceability. Furthermore, the accuracy of traceability can be improved by specifying the same spelling synonyms and preventing the wrong traceability from being ensured.
