Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus, and particularly when a plurality of APs (application programs) of different types operate and each AP handles data in a data format unique to the AP. The present invention relates to a data conversion management method and an information processing device which are suitable for each other.

[0002]

2. Description of the Related Art Generally, a plurality of APs of different types operate on an information processing device. Currently, there are many APs such as document creation, spreadsheet, database, and mail. And
The user can select the optimum AP corresponding to the work, and can improve the efficiency of each work. Further, the above-described respective jobs are often related to each other, for example, by combining documents created by each section to create a document for a department or distributing the created document by mail. In order to improve the efficiency of this collaborative work, it is necessary to mutually use data between business functions.

[0003] Further, the user is unwilling to use an AP having an operability different from that which he has conventionally used, regardless of whether the operability is good or bad. For example, a user who has used a word processor of company A as an AP for creating documents is unwilling to switch to the word processor of company B even if the operability of the word processor of company B is excellent. It is time-consuming and troublesome to get used to a word processor with different operability. Therefore, even if the same document is created, it is necessary to convert the data format between APs in order to make mutual use of data among a plurality of users.

In many cases, the user selects and uses an AP that is most suitable for his / her business and has the best function and operability for each business. A corresponding to each business function such as document creation, spreadsheet, database, mail, etc.
Each company sells P, but the best (operability, function) AP is not always sold by the same company. Data format conversion is often required between APs of different companies.

As described above, in the information processing apparatus, the processing result of one AP may be input to another AP. At this time, if the data format of the data output or input by each AP is different, it is necessary to perform conversion of the data format (hereinafter referred to as data conversion). In this case, after writing the output result of the first AP to a file and ending the operation, first, an AP for data conversion for converting the data format of the AP into the data format of the AP that intends to use the output result is set. Start up and convert data. Next, it is a general method to utilize a second AP that uses the data.

Also, after using the first AP, the second A
If the procedure of using P is predetermined, the procedure of activating the AP for data conversion to perform data conversion after using the first AP and then activating the second AP is previously set by the procedure ( It may be called as a batch file), and the procedure may be started. In addition, there is a second AP that inspects the data format of input data and performs data conversion suitable for the data format, and then inputs the data.

As a conventional technique for automatically converting the data format between programs, there is one disclosed in Japanese Patent Laid-Open No. 1-258122. In the conventional technique, the user inputs a processing procedure for data, and the processing procedure is stored in the processing procedure storage unit. Then, the processing procedure execution unit sequentially performs processing according to the processing procedure stored in the processing procedure storage unit. When performing each process stored in the process procedure storage unit, the processing procedure execution unit compares the data format of the data that is the input of the processing with the data format that the processing can accept in the data format conversion unit, and If there is a difference in format, data conversion will be performed automatically. In this example,
When inputting the processing procedure, the user does not need to consider the difference in the data format between the processings. .

[0008]

The above-mentioned prior art has the following problems.

In the conventional example in which the user activates the data conversion AP, the operation is troublesome and troublesome. Further, there is a problem that it is difficult for the user to understand which data format should be converted to which data format, and it is difficult to understand the existence and usage of the AP for data conversion suitable for the data conversion.

In addition, since general knowledge such as procedure grammar is required to create a procedure, it is difficult for a general user to create a procedure. In addition, even if a procedure is created, many users often do not know the existence and usage of the procedure, which makes it difficult to use the procedure.

Further, in the third conventional example disclosed in Japanese Patent Application Laid-Open No. 1-258122, the user does not need to consider the data difference between the APs, but the user can convert the data in advance. You must enter the procedure and data format. Since the user of the first AP and the user who activates the second AP are often different, it is not possible to determine in which AP the data output to the file by a certain first AP is in the data format. There are many. Furthermore, AP
The data format input or output by is not limited to one type.

The AP does not always input data at the beginning of the process and output the data at the end. For example, when opening a file and reading / writing the file, data conversion is required at the time of opening. That is, the actual AP inputs and outputs data of various data formats at various timings. In addition, in writing, the conventional example does not consider performing inverse conversion. As described above, the third conventional example does not correspond to the usage situation in which the processing order of the processing is not determined. In the third conventional example, since the processing execution control unit performs data conversion suitable for the processing stored in the processing procedure, only one data conversion can be expected for each processing. One process cannot handle when inputting or outputting data of various data formats at various timings.

Further, the above-mentioned conventional example does not consider a method of coping with the case where data conversion cannot be completely performed. The data conversion is desired to be performed on an operating system program (OS) in a familiar environment.

An object of the present invention is to solve the conventional problems and provide an information processing apparatus for converting data having different data formats without making the user aware of the data.

Further, the type of data format in the data conversion unit can be the type of character code system of data. Further, the type of data format in the data conversion unit may be the type of language indicated by the data.

Further, the data inspection means correlates the frequency distribution of the appearance frequency of the data having a predetermined data length and the frequency distribution in a plurality of predetermined data formats with respect to the data received by the input / output means. The respective numbers are obtained, and the format of the received data is determined to be the maximum correlation coefficient data format based on the obtained results. Alternatively, the data inspection means may determine the format of the data received by the input / output means based on an attribute related to the data format, which is added to the data in advance.

The conversion means comprises a data conversion management table that stores in advance a conversion procedure for converting the data format into another data format in association with the data format. As a result of the judgment by the judging means, if the data format cannot be processed, the data converting section generates a predetermined message as to whether or not to convert the data format of the data, and the input / output means , Outputting the message, receiving an instruction as to whether or not to convert the data format, and the conversion means of the data conversion unit outputs the data of the data when the input / output means receives the conversion instruction of the data format. The data format may be converted.

Further, the data conversion management table further stores a ratio indicating the completeness of conversion corresponding to the conversion procedure, and when the message is output from the data conversion unit,
It is possible to further output a message corresponding to the rate indicating the completeness of the conversion.

Further, the conversion means may not convert the data format in the case of a predetermined processing procedure. For example, if the AP is an editor,
Since the purpose is to edit the data code, it is decided in advance not to perform conversion. Further, the data received by the input / output unit can be a result executed in another processing procedure.

[0024]

This determination is made by referring to the data formats managed by the data format management means and which can be processed by the plurality of processing means.

As a result of the judgment by the judging means, if the data format cannot be processed, the data converting means converts it into a data format which can be processed in the processing procedure to be executed. Further, before the conversion, the data conversion unit outputs a predetermined message as to whether or not the data format is to be converted, and the input / output unit outputs the message to determine whether or not to convert the data format. Alternatively, the conversion unit of the data conversion unit may convert the data format of the data when the input / output unit receives the conversion instruction of the data format.

In FIG. 1, the AP 301 is the file 40.
0a access, data conversion control processing 302
Is called, and the data conversion control 302 compares the data format that the AP 301 can handle with the data format of the file 400a. If the data format is different as a result of the comparison, the data format is converted.

First, in the data conversion control 302, the AP inspection processing 308 is called to specify the AP 301 that is trying to access the file. AP inspection process 308
Identifies the AP 301 from the AP name 309 of the AP being executed described in the OS 305, and refers to the data format management table shown in FIG. 6 to identify the data format that the AP 301 can handle. Next, the data inspection process 303 is called, and the data inspection process 303 specifies the data format of the file 400a to be accessed. Then, the data inspection process 303 compares the data format that the AP 301 can handle with the file 400a. If the data format is different,
The data conversion control 302 refers to the data conversion program management table shown in FIG. 5 and selects and calls the corresponding data conversion program 304 to generate a file 400b into which the data has been converted. Access to.

Next, the processing of each unit shown in FIG. 1 will be described in detail.

First, the data inspection processing 303 will be described using the processing flow shown in FIG. In the data inspection processing 303 of this embodiment, the correlation coefficient is used to determine the data format. The data inspection process 303 includes
The frequency distribution table f _r = Σ _i (x _i , 256) of numerical values in each character code system corresponding to each data format is prepared in advance. In addition, x is the appearance frequency of the numerical value in each numerical value 0-255. For the calculation method of the correlation coefficient, refer to "Statistical analysis" published by Nikka Giren Publishing Co., Ltd.
See pages 206-210. The difference in the frequency distribution depending on the language is described in Chapter 2 of the "Basic Cryptography", Volume 2, published by Science Corporation. In FIG. 7, the data inspection process 303 first reads the file 400a to be accessed (process 710), then decomposes part or all of the data of the read file into byte units, and then determines the value of each byte. As numerical data, a frequency distribution f _O = Σ _i (x _i , 256) of the numerical values is created (process 720). Next, a frequency distribution f _r = Σ _i (x _i , x _i ,
256) and calculating the correlation coefficient between f _O. The result of the calculation,
Most character code system of the correlation coefficient was greater f _r data 440 of the file 400a character code system used, that is, the data format (processing 730). 19 and 20 show examples of different character code systems. 19 and 20, “upper” is the value of the upper 4 bits of each byte, and “lower” is the value of the lower 4 bits of each byte. For example, the file 400a
19 is described in the character code system 1 shown in FIG. 19, f _O has the strongest correlation with f _r of the character code system 1, and a correlation coefficient having a large value is calculated.
It is determined that the data 440 of the file 400a is described in the character code system 1. However, if the correlation coefficient is 0.3 or less with any of the character code systems prepared in advance, the data format cannot be determined. In the processing of 730, if the data format cannot be determined,
The message shown in 3 (e) is displayed on the display device 240, and the processing relating to the file access is ended.

In the processing of the processing 720 described above, analysis is performed in byte units. However, since the Kanji code is 2 bytes, in addition to the above-mentioned analysis in byte units, JIS and new JIS
It is also conceivable to calculate the correlation coefficient with f _r of the Kanji code system such as, for example, in units of 2 bytes, and adopt the one with the higher correlation coefficient value.

In general, an AP often gives a file name 410 having an extension 413 unique to the AP to the file 400. Therefore, it is possible to judge the data format by the following method. In this case, a data extension search table 1800 shown in FIG. 18 is provided instead of the frequency distribution table. The data extension search table 1800 shows the correspondence between the extension 413 of the file name 410 and the data format. The data extension search table 1800 is composed of a plurality of records, and each record has an extension 1810 and an AP name 182.
0, data format number 1830 and data format name 18
It consists of 40. The AP name 1820 is the extension 1810.
Is the name of the AP 301 corresponding to. Data format number 1
An identification number 830 uniquely identifies the data format. The data format name 1840 is the name of the data format. Then, the data inspection process 303 acquires the data format number corresponding to the extension 413 from the data extension search table 1800 using the extension 413 of the access target file name 410 as a key. Thereby, the data format can be determined. As described above, the extension 413 is "EXE" for the load module of the processing program, "JXW" for the text data of the word processing software of Company A, and "JXW" for the text data of the word processing software of Company B. It can be identified according to each data format, such as "XJW" or "C" for a C language source.

It is also conceivable to judge a language such as Japanese, English or German. In this case, first, as shown in FIG. 15, after the character code system is determined (process 1510), the language is determined based on the character code system (process 1520). Generally, the letter "a" ~
The frequency distribution f _r = _{Σa to} z (x _i , 26) of “z” differs depending on the language. Therefore, the data 4 of the conversion source file 400a
Frequency of the letter "a" to "z" in the 40 distribution f _O = Σ
_{a to z} (x _i , 26) and frequency distribution f _r = Σ in each language
obtaining a correlation coefficient between _{a~ z (x i, 26)} . The language determination method based on the correlation coefficient is described in Chapter 1 of Volume 2 of "Basic Cryptography" published by Science Co., Ltd. Then, the data 440, determines that described in highest languages frequency distribution f _r the correlation coefficient is calculated for. In this case, the data format is a combination of the character code system and the type of language.

Next, the data conversion control process 302 will be described with reference to FIG. Data conversion control process 302
Is called when the AP 400 accesses the file 400a. Then, the data conversion control process 302
Creates, opens, reads, writes, closes files,
Processes 820a-e corresponding to the type of access such as deletion are performed (process 810). The file generation processing 820a performs normal file generation processing without performing processing related to data conversion. Further, the file deletion process 820e also performs a normal file deletion process without performing a process related to data conversion. The other processes 820b to 820 are processes related to data conversion, and the details will be described below.

First, the file open process 820b of the data conversion control process 302 will be described with reference to FIG. In the operating system program,
When a file open instruction is received from the input means,
The process moves to the file open process 820b. The file open process 820b starts with the AP inspection process 10
Do 10. In the AP inspection process, the AP name is acquired from the running AP name 309 stored in the OS 305 (process 1010). The AP name 309 is AP3.
When the file 400 storing the load module 01 is executed, the front part 411 of the file name 440 of the file 400 is stored. Next, the above-mentioned data inspection process is performed (process 303). Next, the data conversion unit 30
Using the data format management table 600, using the AP name 309 acquired in the AP inspection processing 1010 as the key 620, acquires the data format number 630 of the data format that the AP 301 can handle, and acquired in the data inspection processing 303. Compare with the data format number. If the data format numbers match, a normal file open process is performed (process 1030), and if different, the process shifts to a data conversion program determination process 1040 (process 1020).

In the data conversion program determination processing, the data conversion program management table 500 is used to convert the data format number acquired in the processing 1010 into the conversion destination data format number 510 and the data format number acquired in the processing 303. As the original data format number 520, the corresponding conversion program number 530 and conversion grade 540 are acquired (process 1040). Further, in order to check whether or not the reverse conversion is possible, the data format number acquired in step 1010 is set as the conversion source data format number 520, and the data format number acquired in step 303 is set as the conversion destination data format number 510. The program number 530 and the conversion grade 540 are acquired. Then, based on the result of the processing 1040, the data conversion message is displayed on the display device 24.
It is displayed in 0 (process 1050). As the data conversion message, in the process 1040, when the data conversion program management table 500 is referred to and there is no matching data format number set 510 and 520, data conversion as shown in FIG. The message is displayed on the display device 240. On the other hand, if there is a set of matching data format numbers 510 and 520 and data conversion is possible, the data conversion message of FIG. 13A is displayed on the display device 240. However, when the value of the conversion grade 540 is 99 or less, the message of FIG. 13B is displayed. When the value of the conversion grade of reverse conversion is 99 or less, the message of FIG. When there is no set of format numbers 510 and 520, the message of FIG. 13D is displayed on the display device 240 together with the data conversion message of FIG. 13A (process 1050). Alternatively, the value of the conversion grade may be indicated. If data conversion is impossible, or if the user uses the keyboard 25 of the input means.
If 0 or the mouse 251 is instructed to "cancel" the data conversion, the process is terminated (process 1060). On the other hand, when the instruction to perform the data conversion is received, the work file 400b that stores the data after the data conversion is generated (process 1070). And the generated work file 4
The name of 00b is registered in the work file name 920 of the data conversion control table 900. At the same time, the name of the file 400a to be opened is registered in the conversion source file name 910, and the conversion program number 530 acquired in process 1040 is registered in 930 (process 1080). Next, the data conversion process 304 is called. The data conversion process 304 will be described later in detail. Finally, the work file 400b is opened (process 109).
0).

As described above, the file open processing 820b can be performed for files having different data formats.

Next, the file read / write process 820c of the data conversion control process 302 will be described with reference to FIG. In the operating system, when a file read / write instruction is received from the input means, the process proceeds to the file read / write processing 820c. File read / write process 82
0c is the file 400a to be read / written first.
Data conversion control table 900 to determine whether the file 400 has been converted.
It is checked whether or not the file name 410 of a is registered in the conversion source file name 910 (process 1110). If the file is not registered, the file 400a is read and written as it is (process 1120) and the process ends (process 11).
30). If the file is not registered, it is determined that the conversion is unnecessary when the file is opened because the data format does not differ, and thus the file 400a can be read and written as it is. On the other hand, if registered, the file is read / written by the work file name 920 corresponding to the conversion source file name 910 (process 1120), and if written, the reading record 940 Is recorded (step 1140).
For example, a flag indicating that writing has been performed is set. For the written file, it is necessary to perform the reverse conversion when the file is closed.
Record it in.

As described above, files having different data formats can be read / written by reading / writing the converted files.

Next, the file close processing 820d of the data conversion control processing 302 will be described with reference to FIG. In the operating system, when a file read / write instruction is received from the input means, the process proceeds to the file close processing 820d. File close processing 82
0d is the file 400a to be closed first.
Data conversion control table 900 to determine whether the file 400 has been converted.
It is checked whether or not the file name 410 of a is registered in the conversion source file name 910 (process 1210). If it is not registered, the file is closed as it is (process 1230) and the process ends (process 1120).
Also, the file 40 of the data conversion control table 900
If there is no record of writing in the reading record 940 corresponding to 0a, the work file 400b of the work file name 920 corresponding to the conversion source file name 910 is deleted, and the work file name 920 in the data conversion control table 900 is deleted. The record described by is deleted (process 1240). On the other hand, when the file name 410 of the file 400a is registered in the conversion source file name 910, the work file name 920 and the conversion program number 930 are acquired from the data conversion control table 900 (process 1250). Next, using the data conversion program management table 500, the matching conversion program number 530 is detected using the conversion program number 930 acquired in the process 1250 as a key, and the corresponding conversion source data format number 510 and conversion destination data format number 520 are detected. To get.
Then, in order to obtain the conversion program number of the reverse conversion, a record in which the conversion source data format number 510 matches the conversion destination data format number 520 and the conversion destination data format number 520 matches the conversion source data format number 510, respectively. It retrieves and acquires the conversion program number 530 and the conversion grade 540 of the record (process 1260). Next,
The data message shown in FIG. 13 is displayed based on the result of the process 1260 (process 1270). The data conversion message is shown in FIG. 13 when there is no pair of data format numbers 510 and 520 matching the reverse conversion in the data conversion program management table 500 in the process 1270.
The data conversion message as shown in (e) is displayed on the display device 240. On the other hand, if there is a set of matching data format numbers 510 and 520 and data conversion is possible, the data conversion message of FIG. 13A is displayed on the display device 240. However, conversion grade 54
When the value of 0 is 99 or less, the message of FIG. 13B is displayed on the display device 240 together with the data conversion message of FIG. Then, if the data conversion is impossible, or if the user gives an instruction to "cancel" the data conversion, the process ends (process 1280). on the other hand,
When performing data conversion, the data conversion processing 304 is called to perform data conversion, and the converted data is stored in the original file after conversion. Then, the work file 400b having the work file name 920 acquired in the process 1250 is deleted (process 1290).

Next, the data conversion process 304 will be described. The data conversion process 304 first opens the conversion source file 400a that is the access target (14
10) Next, the conversion destination work file 400b generated in the process 1070 in FIG. 10 is opened (1
420). Next, the data 440 stored in the file 400a is read onto the main memory 210 (143
0), data conversion is performed (1440). Data conversion will be described later in detail. Then, the converted data is written to the work file 400b (145
0). The file 400a and the work file 400b are closed (1460, 1470).

The data conversion programs 304a to 304e have different types depending on the combination of the data format of the conversion source and the data format of the conversion destination, and the processing 1440 also differs accordingly. As an example of the processing 1440, for example, FIG.
In the conversion from the data of the data format having the character code system as shown in FIG. 9 to the data of the data format having the character code system as shown in FIG. 20, the data is read byte by byte, and as shown in FIG. Convert according to the character code conversion table. The character code conversion table as shown in FIG.
It can be processed by defining it in the program of 4e.

The conversion of the data format is not limited to the conversion of the character code system. For example, in the case of a document file, attributes such as Gothic, Mincho, double-width, half-width, etc. attached to each character, or the page format such as character spacing, line spacing, and top, bottom, left, and right margins are maintained. Data conversion to.

Furthermore, it is also possible to convert languages such as Japanese, English, and German. For example, when the data inspection process determines that the data 440 of the file 400a is an English document and the AP inspection process 307 determines that the AP 301 is a Japanese word processor, the file open process 820b converts English to Japanese. Do. However, if the AP inspection processing 307 determines that the AP 301 is an editor for creating a program, conversion is not performed even if the data 440 of the file 400a is determined to be an English document.

Although an example of a stand-alone information processing apparatus has been described above, an example in which the above information processing apparatuses are connected to each other using a communication line 2200 is also conceivable as shown in FIG. In such an embodiment, the AP operating on the first information processing device may access a file stored in the second information processing device. In that case, the data conversion control processing 302, the data inspection processing 303 of the processing program related to the data conversion,
The AP inspection process 307 and the data conversion process 304 may use either the first information processing device or the second information processing device. In addition, the data conversion program 304
May be stored in a specific information processing device and shared (called) by each information processing device. In that case, it is not necessary to prepare various data conversion programs 304 in each information processing apparatus, and it is possible to reduce the used capacity of the storage device in each information processing apparatus and simplify the management of the data conversion program 304.

As described above, when the AP accesses the file, including the character code system and the language type,
Determine the data format of the file and the AP data format,
When the data formats are different from each other, the contents of the file are automatically converted into the data format of the AP, so that the user of the information processing apparatus is not aware of the difference in the data format between the APs. The burden on the user can be reduced. Further, in each processing such as file opening, file reading / writing, and file closing, data conversion control processing is performed, so that data conversion can be performed at various timings.
