Description

  The present invention relates to a technique for associating characters used between information processing apparatuses having different character code systems.

  In data linkage between different platforms with different character code systems, it is necessary to convert the character code system at the time of transfer.

  When data linkage is performed by converting the character code system, for example, each character code table is printed by each information processing apparatus, and the correspondence definition of the character code is created in advance by manual association. The character code conversion device performs data linkage by converting the character code received from one information processing device and transmitting the character code to the other information processing device using this correspondence definition.

Also, when data linkage occurs between many systems, a specific character code (Shift JIS
In general, an approach that eliminates the need for character code conversion is standardized.

Further, as related prior art, for example, there is a technique disclosed in the following patent document.

Data integration between systems with different character code systems becomes difficult due to system integration by merger and reorganization, or system integration by core system reconstruction, SOA (Service Oriented Architecture), B2B (business-to-business), etc. Yes.

  In the era when business systems worked independently, character codes were often associated with each system independently. However, due to the increase in cooperation between the systems mentioned above, this problem is complicated by having to rebuild the associations that were performed independently when integrating and linking these systems. It has become.

  If the character code system is different, the code numbers and sets of the characters included therein are also different. In order to prevent so-called “garbled characters”, it is basically necessary to manually determine how to deal with these characters. However, as the opportunities for data linkage increase, there is a problem that the task of matching characters becomes a heavy burden.

  In addition, when character code conversion is not required by unifying to a specific character code, it is necessary to modify the database and application, and there is a problem that the degree of difficulty increases as the scale of the current system increases.

  Therefore, the disclosed method or method in the present case provides a technique for matching character codes between information processing systems using a master character set based on a character shape.

As an embodiment of the present invention for solving the above problems, there are a conversion management device, a conversion management program, a recording medium on which the conversion management program is recorded, and a conversion management method.

These things or methods are
Receiving character data including a character shape and a character code used in the information processing system from a plurality of information processing systems having different character code systems;
A master character set that compares the character shape of each character based on the character data, assigns a master code every time the character shape is different, and associates the character shape with the master code for all characters used in the plurality of information processing systems Produces
Based on the master character set and the character data received from the information processing system, a correspondence relationship between the character code of the character used in the first information processing system and the master code among the plurality of information processing systems is obtained. The correspondence between the character code of the character used in the second information processing system and the master code is obtained, and the character code of the character used in the first information processing system corresponding to the same master code is used in the second information processing system. A conversion table between the first information processing system and the second information processing system is generated in association with the character code of the character to be processed.

  According to the method or method disclosed in the present disclosure, it is possible to provide a technique for matching character codes between information processing systems using a master character set based on a character shape.

  The best mode for carrying out the present invention will be described below with reference to the drawings. The configuration of the following embodiment is an exemplification, and the present invention is not limited to the configuration of the embodiment.

  FIG. 1 is a schematic diagram of a cooperation system according to the present embodiment. The core linkage system 10 of this example includes a data linkage server 2 that links a plurality of business systems 1, a character code conversion server 3 that converts a character code processed by the data linkage server 2, and the character code conversion server 3. And a master character set management server 4 that distributes the conversion table.

  The plurality of business systems 1 may be any information processing system that performs processing of information including character data, for example, electronic commerce, management of customer information, data distribution, etc., and has business systems 1A to 1C in the example of FIG. ing.

  The data cooperation server 2 receives a message in a predetermined format from each business system 1, converts it appropriately, transmits the message to another business system, and performs data cooperation between the business systems.

  The character code conversion server 3 receives the source and destination business server names and character codes from the data linkage server 2, and transmits the source character codes based on the conversion table distributed from the master character set management server 4. Convert to the previous character code.

FIG. 2 is a schematic diagram of the master character set management server 4 which is the conversion management apparatus of this example. As shown in FIG. 2, the master character set management server 4 has a central processing unit (CPU) in the main body.
unit) 12, a main memory 13, an input / output port (I / O) 14, and the like.

  The input / output port 14 includes an input unit 15 for inputting user instructions such as a keyboard and a mouse, a storage unit 16 such as a hard disk storing data and software for arithmetic processing, and communication for controlling communication with other computers. A network adapter 17 and a display device 18 functioning as a control unit are connected.

  The storage unit 16 is preinstalled with application software such as an operating system (OS) and a conversion management program, and a network driver.

  The CPU 12 appropriately reads out and executes the OS and application programs from the storage unit 16 via the main memory 13 and executes processing on the information read out from the network adapter 17 and the storage unit 16, as shown in FIG. It also functions as a data acquisition unit 21, a master generation unit 22, a table generation unit 23, an external character registration unit 24, and a candidate presentation unit 25.

  The CPU 12 as the character data acquisition unit 21 receives character data including a character shape and a character code used in the business system 1 from a plurality of business systems 1 having different character code systems.

  The CPU 12 as the master generation unit 22 compares the character shape of each character based on the character data, assigns a master code every time the character shape is different, and the character shape and the master code for all characters used in the plurality of business systems 1. A master character set that associates with is generated.

  The CPU 12 as the table generation unit 23 generates a conversion table between the business systems based on the master character set and the character data received from the business system 1. For this reason, the table generation unit 23 obtains the correspondence between the character code of the character used in the first business system, for example, the business system 1B, and the master code among the plurality of business systems 1. In addition, the table generation unit 23 obtains a correspondence relationship between the character code of the character used in the second business system, that is, the business system 1A or 1C other than the first, and the master code. Then, the table generation unit 23 associates the character code of the character used in the first business system 1 corresponding to the same master code with the character code of the character used in the second business system 1, and A conversion table between the system 1 and the second business system 1 is generated.

  As the external character registration unit 24, the CPU 12 selects characters that are used in the first business system 1 and have characters corresponding to the same master code that are not included in the characters used in the second business system 1. Register as external characters in the system 1.

  The CPU 12 as the candidate presentation unit 25 displays a corresponding character candidate on the display device 18 based on auxiliary information of a character to be described later for characters that could not be automatically associated, and allows the user to input characters corresponding to the candidate presentation unit 25. That is, the association is performed on the GUI.

  A conversion management method executed by the master character set management server 4 in accordance with the conversion management program will be described below.

  FIG. 3 is an explanatory diagram of the conversion management method of this example.

  First, the character data acquisition unit 21 receives character data of all characters used in the business system 1. Moreover, the master production | generation part 22 produces | generates a master character set by providing a master code, whenever a character shape differs (step S1).

  The master generation part 22 registers the relationship information between characters, such as the variant character and similarity of a master character set, in a master character set.

FIG. 4 is an explanatory diagram of the relationship information between characters in the master character set. In the example of FIG. 4, # 101 to # 103 are in a variant relationship, and # 104 and # 105 are in another variant relationship. In the example of FIG. 4, the similarity between # 101 and # 102 is 50%, and the similarity between # 101 and # 103 is 10%.

  Further, the master generation unit displays an input form on the display device 18 to prompt input of attribute information of each character, that is, a character attribute, and registers the input character attribute in the character master set (S3).

  The auxiliary information such as the character attribute and the relationship information between characters is recorded in each record for each master code as shown in FIGS.

  As shown in FIG. 7, the table generation unit 23 creates a table in which the character codes of each business system 1 are associated with the master codes of the master character set. In addition, as shown in FIG. 8, you may create the table which matched the character code of the several business system 1 with the master code | cord | chord.

  Then, the table generating unit 23 newly generates a conversion table between the first business system 1B and the second business system 1A as shown in FIG. At this stage, only the character code of the character used in the business system 1B is recorded, and the character code of the corresponding business system 1A is empty (S4). In this example, it is assumed that the conversion tables of the business system 1B and the business system 1C have already been operated as shown in FIG.

  The table generation unit 23 reads the conversion table already in operation and the conversion rule that is generally used from the storage unit 16 (S5). In general character code systems such as JIS code, Unicode, and JEF, the correspondence relationship (conversion rule) of character codes other than external characters is already used, and this conversion rule is stored in the storage unit 16 in advance.

  Next, the table generating unit 23 prompts the setting of the business policy of each business system 1B, 1A by displaying an input form on the display unit 18 or the like.

  FIG. 11 is an explanatory diagram of a business policy. This business policy includes items such as character code type, character identification rule, identification with similar characters, identification with variant characters, and automatic external character definition. Specific contents will be described later.

  According to the input business policy, the table generating unit 23 associates the character codes of the business system 1A and the business system 1B (S7).

  The candidate presentation unit 25 displays an advisor window 51 on the display unit 18 as shown in FIG. 12 for characters that are not automatically determined by the character identification rules set in the business policy, and based on the auxiliary information. Variants and similar characters are presented as candidates, and the user is prompted to select (S8).

If there is a corresponding character in the candidate and the user selects it (S9 Yes), the character code of the selected character is associated with the conversion source character code (S11), that is, association is performed using the GUI.

On the other hand, when there is no corresponding character in the candidate and the user closes the window 51 without selecting it or selects external character registration (No in S9), the external character registration unit 24 sends the character data of the conversion source character to the business system. 1B is transmitted to register the external character, and the character code of this external character is acquired. The table generation unit 23 registers the external character code and the conversion source character code in the conversion table in association with each other.

As described above, the character codes can be associated with each other almost automatically, and characters that could not be automatically associated can be associated with a simple operation, so that a conversion table can be easily created.

  The character identification performed in S7 will be described in detail below.

  In the item of the character identification rule of FIG. 11, the “standard code conversion rule” is to identify a corresponding character using a conversion rule generally used based on the character code system specified by the character code system type. To do.

  “Master character set number match” is to identify the corresponding character when the master codes of the two characters match. This shows that the two characters are the same even when compared according to the strictest standard in this system.

  The “variant character” means that if there is a variant character such as a side and a heel, it is regarded as the same.

  “Similar characters” are considered to be the same when the degree of similarity between the master character sets of two characters satisfies the criteria defined in advance in the policy.

  The “specific correspondence definition” is regarded as the same if the correspondence between the two character codes is included in other conversion rules in operation.

  Moreover, the item of identification determination with a similar character shows the reference | standard which considers two similar characters as the same.

  The item of identification with a variant character sets whether or not the variant character is regarded as the same. Different characters regarded as the same may be set individually. If only the presence / absence of variant character identification is indicated, it may be determined based on whether or not the variant character is set in the character identification rule, and this item may be omitted.

  The automatic external character definition item includes characters that are used in the information processing system of the conversion source and characters that do not have characters corresponding to the same master code in the information processing system of the conversion destination. Indicates whether or not to automatically register as an external character.

  FIG. 13 shows an example of setting a business policy for the business systems 1A and 1B. Note that the character identification rules are applied in the order of description. That is, in FIG. 12, after the characters are associated according to the standard code conversion rule, the association is performed using the master character set.

For example, in the new state shown in FIG. 9, first, a standard code conversion rule is applied, and association is performed according to a general conversion rule between Unicode and SJIS. In the example of FIG. 14, a character code 90C4 corresponding to the character code 6589 and a character code 95B7 corresponding to the character code 805E are registered.

  A character that cannot be handled by the standard code conversion rule is associated with a character having a matching master code by using a master character set. In the example of FIG. 15, the character code F041 corresponding to the character code E533 is registered.

  Then, the characters whose master codes do not match are associated according to a specific correspondence definition. In this example, the corresponding characters in the conversion tables of the other business systems 1C and 1B are regarded as the same character. In FIG. 16, the character code 95B7 corresponding to the character code E259 is registered.

As described above, this embodiment solves the problem of the character code work load that occurs for each data linkage by automating the character code association work and reducing the work addition.

  In this embodiment, data linkage is performed by character code conversion without changing the character code of the linkage target system. Therefore, it becomes possible to perform inter-system cooperation while utilizing the current accumulated data and application assets.

Furthermore, the following effects can be obtained.
1. Easily formulate rules for character code conversion, leading to reduced work costs
2. Since character code conversion rules are formulated based on the only master character set in the system, garbled troubles can be prevented.
3. Even if a garbled problem occurs, the information related to the master character set and the external character font processing function can quickly handle the problem.
4. It is easy to link tasks with different character usage policies.

In addition, the following business impacts can be given. 1. By reducing the work cost of code conversion, system integration and inter-system collaboration with mixed character codes are promoted.
2. In SOAs that require dynamic linkage between systems, SOA can be promoted by reducing the problem of mixed character codes.
3. It will be easier for the system to deal with character standards that are expected to continue to change in the future, such as JIS78, JIS83, JIS90, JIS97, and JIS2004. The reason is that by providing the correspondence rule with the master character set as a product, the user can obtain the correspondence rule with the new code system without doing anything.

The present invention is not limited to the illustrated examples described above, and various modifications can be made without departing from the scope of the present invention.

  For example, the same effects as those of the above-described embodiment can be obtained even with the configurations described below. These components can be combined as much as possible.
