Description

TECHNICAL FIELD [0001] The present invention relates to an electronic file storage apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electronic file storage device and a method of operating the same, and more particularly, to an electronic file storage device for automatically classifying and storing various types of electronic files according to their own formats and a method for operating the same .

After entering the information society, accumulated data are kept in electronic files, which are soft copies rather than hard copies. It is now common practice to keep documents in the form of soft copies by scanning up to past archived hard copy documents. As time goes by, these electronic files become large in capacity and various categories.

There is a lot of research on how to categorize and store such large-capacity electronic files by category. Currently, the basic usage of PCs can be rearranged in a certain order according to specific conditions such as name, modification date, file type, and file size. That is, electronic files can be classified within the limits of metadata (attribute information).

However, due to user errors, frequent copying of electronic files, online transmission, and malfunctioning of programs, metadata is often damaged, making it impossible to classify by category. In spite of the addition of specific classification conditions, I will make an error.

Further, when there is no program capable of reading the electronic file, information of the metadata itself can not be grasped, such as a new electronic file generated by a newly developed program, or new electronic files that are incorrectly identified and not classified by category It becomes impossible to classify and store a huge amount of electronic files by category.

An index structure of metadata, a method of providing indexes of metadata, a method and a device for searching metadata using an index of metadata (Korean Patent Registration No. 10-0419766) A method of automating an archiving task (Korean Patent Laid-Open Publication No. 10-2014-0072929)

It is an object of the present invention to provide an electronic file storage device and a method of operating the electronic file storage device which can classify electronic file categories more accurately and quickly than the limit of metadata information.

It is another object of the present invention to provide an electronic file storage device for storing information of an electronic file and classifying and storing new electronic files generated by a new program by category and a method for operating the electronic file storage device.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide an electronic file storage device for classifying the string patterns containing unique formats of electronic files by categories and a method for operating the same.

The electronic file archiving apparatus according to an embodiment of the present invention includes a storage unit for storing electronic files and grouping the same types of character string patterns according to the format of the electronic files into one group and classified into categories, A pattern conversion unit for converting the format of a new electronic file supplied from the outside into a character string pattern so as to correspond to a character string pattern to be stored; a character string pattern of the new electronic file supplied from the pattern conversion unit; And a pattern analysis unit for analyzing the identity and designating a category of the same string pattern and sending the same to the storage unit.

Wherein the storage unit includes a main storage unit for storing electronic files having the same character string pattern by category and a sub storage unit for storing new electronic files not stored in the main storage unit, A new electronic file having a character string pattern that is not the same as the new electronic file can be sent to the sub storage unit.

The sub-storage unit may transmit the new electronic files to the pattern analysis unit when the number of new electronic files matching the stored character string pattern reaches a predetermined set value. The pattern analyzer may assign a new category to the new electronic files and send the new electronic files to the main storage unit.

The manner in which the pattern analysis sub-category is specified may be to insert or modify metadata or extensions of electronic files and may also insert an identification string pattern into a string pattern of electronic files.

A method for storing electronic files according to an embodiment of the present invention includes the steps of: (a) converting a format of the electronic file supplied from the outside into a character string pattern; (b) (C) designating a category of a previously stored electronic file having the same identity as a character string pattern of the electronic file to the electronic file; and (d) And grouping them into one group together with the same existing electronic files and storing them in the main storage unit.

The step (b) may further include designating an electronic file having a string pattern that is not the same as the string pattern of the previously stored electronic file as a new electronic file and storing the electronic file in the sub-storage unit. The step (b) may further include checking whether the number of new electronic files having the same string pattern has reached a predetermined set value as the new electronic file is stored in the sub-storing unit.

The step (c) may further include the step of assigning a new category to the new electronic files that have reached the predetermined set value. The method of designating the category may include inserting or modifying the metadata or extension of the new electronic files and inserting the identification string pattern into the string pattern of the new electronic files.

The electronic file storage device and the method for operating the electronic file storage device of the present invention are highly accurate compared to the existing classification that relies on metadata because the electronic file format that is different according to the developer's intention is compared in a string pattern format.

In addition, electronic files generated by a newly developed program can be classified and stored for each category because the degree of frequency is checked and converted into a database.

In addition, the electronic file storage device and the method for operating the electronic file storage device of the present invention can classify and store users or electronic files with modified metadata.

In addition, the present invention can easily search an electronic file to be searched by a user because a category is designated by inserting / modifying metadata, an extension, and an identification string pattern based on a character string pattern.

For example, the specific forms, structures, and characteristics described herein may be implemented by changing from one embodiment to another without departing from the spirit and scope of the present invention. It should also be understood that the position or arrangement of individual components within each embodiment may be varied without departing from the spirit and scope of the present invention. Therefore, the following detailed description is not intended to be construed in a limiting sense, and the scope of the present invention should be construed as encompassing all of the scope of the claims and equivalents thereof. In the drawings, like reference numbers designate the same or similar components throughout the several views.

Hereinafter, various embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention.

1 is an internal configuration diagram of an electronic file storage apparatus according to an embodiment of the present invention.

Referring to FIG. 1, an electronic file storage apparatus 100 according to an embodiment of the present invention includes a storage unit 110, a pattern conversion unit 120, and a pattern analysis unit 130. The electronic file storage device 100 includes a recording medium containing a program capable of classifying and storing electronic files according to specific categories, and the type thereof includes a recording medium such as a magnetic disk, a microfilm, an optical disk and the like. It also includes a hardware configuration including such a recording medium and operated by it.

The storage unit 110 stores electronic files, and the electronic files are classified and stored according to categories. The classification by category indicates that character patterns appearing in accordance with the unique format of the electronic files are grouped into one group among the electronic files. The format of the electronic files may be different depending on the intention of the program developer who displays the electronic files, i.e., coding.

Specifically, the formats may be different depending on the types of documents, audio, images, and moving pictures contained in the electronic files. In addition, even for documents of the same kind, it is possible to arrange data such as characters, items, and punctuation marks, arrangement of data at the time of inputting and outputting, signal processing and production method, arrangement of images, arrangement methods of rows and columns of data files, sector, metadata content, and array type. As such, all the various characteristics of the developer's intent are contained in the format of the electronic file.

The storage unit 110 stores electronic files and their formats in a character string pattern. The string pattern indicates that the format of electronic files has been converted into a string code. For example, the string pattern may be represented by a 4-bit hexadecimal code character in the format of electronic files. Additional examples of converting the format of electronic files into a character string pattern will be described in the pattern conversion unit 120 described below.

The storage unit 110 includes a main storage unit 111 and a sub storage unit 112. The main storage unit 111 includes a database storing already known electronic files and a character string in which the format is expressed. Indicates that the user who wants to keep the electronic file has already converted the format of the electronic files into a string pattern.

On the other hand, the sub storage unit 112 stores new electronic files that are not stored in the main storage unit 111. That is, the new electronic file indicates a new electronic file which is first obtained for the purpose of storing in the electronic file storage device 100, and has no part corresponding to the character string pattern of the electronic files stored in the main storage part 111. Therefore, the electronic files stored and stored in the main storage unit 111 do not have the same format as the electronic files stored in the sub storage unit 112. [

On the other hand, when an electronic file having the same character string pattern as that of the new electronic file is input to the sub storage unit 112, the number of electronic files having the same character string pattern can be counted. This is to count new electronic files having a large number of cumulative counts and to select a candidate group to transfer to the main storage unit 111.

The sub-storage unit 112 may transmit the new electronic files to the pattern analyzer 130 when the number of new electronic files matching the stored string pattern reaches a predetermined set value. The predetermined set value is an arbitrary value that can be designated by the user who manages the electronic file storage device and is calculated in consideration of the capacity that can be stored in the main storage unit 111 and the processing time required for character string pattern comparison .

The pattern conversion unit 120 receives an electronic file from the outside for the purpose of storing in the electronic file storage device 100, and converts the format of the electronic file into a character string pattern. The method of converting the format of the electronic file into the character string pattern is the same as the method of converting the format of the electronic files stored in the main storage unit 111 described above into the character string pattern.

FIG. 2 is a schematic diagram showing a pattern conversion unit according to an embodiment of the present invention in which a format of an electronic file is converted into a 4-bit hexadecimal string pattern in units of bits. The character pattern converted by the pattern conversion unit 120 of FIG. 1 is transmitted to the main storage unit 111 or the sub storage unit 112 via the pattern analysis unit 130 together with the corresponding electronic file, do.

The pattern analyzer 130 compares the character string pattern of the electronic file supplied from the pattern conversion unit with the character string pattern of the electronic files stored in the main storage unit 111.

FIG. 3 is a schematic diagram illustrating a method of comparing pattern analysis substrings according to an exemplary embodiment of the present invention. Referring to FIGS. 1 and 3, the pattern analyzer 130 may extract a portion of a comparison character string F among all the character string patterns (upper portion) supplied to the pattern conversion unit 120. At this time, the range for extracting the compared character string pattern F can be variously changed by the pattern analyzer 130 according to the setting, and a character string pattern that is apart from each other can be extracted, Can be adjusted. The electronic files to be extracted by the pattern conversion unit 120 are all electronic files stored in the main storage unit 111. However, in order to quickly find the character string pattern Y that can be matched with the comparison character pattern F, the pattern analyzing unit 130 analyzes the electronic files stored in the main storage unit 111, The electronic files can be first adopted and the character string pattern of the corresponding electronic file can be extracted.

In addition, the pattern analyzer 130 transmits a string pattern (lower portion) of the stored electronic file from the main storage unit 111, and compares them to determine the identity. It is possible to screen a portion of the string pattern (Y) of the electronic file extracted by the main storage unit 111, which coincide with each other. However, the determination of the identity of the string pattern may be made in various ways depending on the setting of the user. For example, unlike the case shown in Fig. 3, even if the positions of columns and rows on the arrangement of character strings are not the same, the character patterns can be regarded as identical if they are only in the same order. Alternatively, it can be determined that the same sequence is the same in a state in which a certain interval of rows or columns is allowed.

The pattern analysis unit 130 assigns the same category to the electronic files having the same character string pattern and sends them to the main storage unit 111. As the pattern analyzing unit 130 designates the category, the storage unit 111 can perform the classification according to the category designated by the pattern analyzing unit 130 simply and rapidly.

The pattern analyzing unit 130 includes a method of designating a category in an electronic file so that the user can easily search for the electronic file. For example, the pattern analyzer 130 may assign the same extension (e.g., * .avi) to electronic files having the same string pattern as the electronic file stored in the main storage unit 111. [ Another example includes a method of inserting or modifying metadata information (file format, connection program information, etc.) stored in the main storage unit into electronic files having the same string pattern. It is preferable to adopt this category designation method when programs that implement the retrieval so that the user can easily browse the electronic file information based on the metadata information are used.

As another example, the pattern analysis unit 110 may insert an identification string pattern into electronic files having the same string pattern as the electronic file stored in the main storage unit 111. [

FIG. 4 is a schematic diagram illustrating a process of inserting an identification character pattern into an electronic file having the same character string pattern shown in FIG. 3. FIG. Referring to FIGS. 1 and 4, an identification string pattern Z can be inserted into an electronic file having the same character pattern (F, Y). The identification string pattern Z can be inserted in the last or last part of the same string pattern F or Y. [ When a program that implements the search so that the user can easily browse the electronic file based on the string pattern information is used, it is preferable to employ this category designation method.

In the case where the character pattern of the electronic file supplied from the pattern conversion unit 120 is a new electronic file which is not confirmed whether the character pattern is the same as the character string stored in the main storage unit 111, It is possible to transmit the string pattern to the sub storage unit 112. The new electronic file is not stored in the main storage unit 111 but is stored in the sub-storage unit 112 separately configured so that the pattern analysis unit 130 may excessively overwrite the target electronic file to be compared with the supplied electronic file It can be prevented that it is stretched.

In this case, the new electronic file has the following characteristics: i) an electronic file (including an electronic file generated by a newly developed program) that is not stored in the main storage unit, Ii) an extension, an electronic file whose metadata information is damaged, and the like.

When the accumulated count number of new electronic files reaches the set value in the sub storage unit 112, the sub storage unit 112 transmits the new electronic files and the corresponding character pattern to the pattern analysis unit 130 . The pattern analysis unit 130 may assign the same new category to the new electronic files received from the sub-storage unit 112. [ At this time, the pattern analyzer 130 may designate a new category for the new electronic files by employing the above-described extension insertion, metadata modification / insertion, and identification string pattern insertion.

The pattern analysis unit 130 may transmit the new electronic files and the corresponding character pattern designated by the new category to the main storage unit 111. [ When the main storage unit 111 stores the new electronic files sent from the pattern analysis unit 130 and the corresponding character pattern in the designated category, the registration of the new electronic file is completed.

Hereinafter, an embodiment will be described with respect to a method of operating the above-described electronic file storage apparatus, for example, in a time series sequence. Therefore, the terms used below should be construed as corresponding categories if they are the same as those used in the electronic file storage device described above.

5 is a flowchart illustrating an electronic file archiving method according to an embodiment of the present invention. Referring to FIG. 5, the electronic file archiving method of the present invention includes the steps of (a) converting a format of the electronic file supplied from the outside into a character string pattern, (B) comparing the string pattern of the electronic file with a string pattern of the electronic file; (c) assigning to the electronic file a category of a previously stored electronic file having an identity with the string pattern of the electronic file; and (D) classified into groups together with the electronic file and stored in the main storage unit. And the string pattern of the previously stored electronic file is identical to the string pattern of the electronic file supplied from the outside, the above-described steps are performed.

In addition, if an electronic file having a string pattern that is not the same as the string pattern of the electronic file previously stored in step (b) is identified, the corresponding electronic file is designated as a new electronic file and the new electronic file is stored (B-1).

Next, as the new electronic file is stored in the sub-storage unit, it is determined whether the number of new electronic files having the same character string pattern has reached a preset value (b-2). When the accumulated number of electronic files reaches the set value, it is preferable that the electronic file having the same character string pattern is stored in the main storage unit and constructed as a database in preparation for the case where the electronic file having the same character string is inputted from the outside.

(C) designating a new category for the new electronic files that have reached the predetermined set value; and (d) storing the electronic files having the same designated category together into a group and being stored in the main storage unit. The method of designating a category includes a method of inserting or modifying metadata or an extension of the new electronic files or a method of inserting an identification string pattern into a string pattern of the new electronic files.

As described above, since the electronic file storage device and the method for operating the electronic file storage device of the present invention compares formats of various types of electronic files according to a developer's intention in a string pattern format, accuracy is high unlike the existing classification that relies on metadata. In addition, electronic files generated by a newly developed program can be classified and stored in categories because they are checked for the degree of frequency and made into a database.

The present invention can also classify electronic files whose metadata has been damaged due to user errors, frequent copying of electronic files, online transmission, and program malfunctions.

In addition, the present invention can easily search an electronic file to be searched by a user because a category is designated by inserting / modifying metadata, an extension, and an identification string pattern based on a character string pattern.
