Description

Electronic device performing parallel processing-based document format conversion and its operating method

The present invention relates to an electronic device that performs document format conversion based on parallel processing and an operating method thereof.

Recently, as various types of document viewing and editing programs have emerged, various types of electronic document formats compatible with these programs have emerged. For example, there are various document formats having extensions such as 'docx', 'hwp', 'pdf', and the like.

As electronic documents of various formats are used, the importance of a format conversion function capable of converting an electronic document created in a specific format into another format is increasing. For example, a format for converting an electronic document written in the 'docx' extension format into an 'hwp' extension format or converting an electronic document created in the 'hwp' extension format into a 'pdf' extension format. The importance of conversion functions is increasing.

In this way, as the importance of the format conversion function of the electronic document increases, the importance of technology for performing the format conversion of the electronic document more quickly is increasing. In this regard, as a method of quickly converting the format of an electronic document into another format, rather than converting the format of pages constituting an electronic document sequentially one by one, a plurality of threads for format conversion are created and then It is possible to consider introducing a method of converting and processing the format of pages in parallel using each thread.

However, in this method of converting the format of pages constituting an electronic document in parallel using multiple threads, format conversion is not completed sequentially according to the order of each page, so format conversion is not necessary for the user. When the completed page is displayed, the page may not be exposed on the screen according to the order of the page, so it may be difficult for the user to determine whether the format conversion of the electronic document is properly performed.

For example, when the format of an electronic document consisting of 10 pages is converted in parallel for each page, it may occur that the format of 8 pages is completed before the format of 1 page. If the format conversion result for the page is first displayed, there is a possibility that the user will recognize that the format conversion operation for the electronic document is not properly performed.

Therefore, a technique for performing format conversion in parallel for each page constituting an electronic document, but showing the format conversion result sequentially according to the page order when showing the format conversion completed page to the user. Research is needed.

In the present invention, when a document format conversion command for a specific electronic document is applied from a user, n threads for converting the document format of each of n (n is a natural number equal to or greater than 2) constituting the specific electronic document are provided. After generating and allocating one of the n pages to the n threads, the n threads are simultaneously executed to simultaneously perform document format conversion for the n pages in parallel, page by page. By presenting an electronic device capable of displaying format-converted pages sequentially on a screen and an operating method thereof according to the present invention, fast format conversion for an electronic document is possible, and at the same time, a user can perform a format conversion operation for an electronic document. We want to support you to intuitively recognize that this is going on normally.

According to an embodiment of the present invention, an electronic device that performs document format conversion based on parallel processing is a first electronic document created by a user in a first document format, wherein n is a natural number equal to or greater than 2. composed of number of pages - when a document format conversion command instructing to convert a document file of the second document format into a document file of the second document format is applied, n threads for converting the document format of each of the n pages (Thread ), when the n threads are created, by allocating one of the n pages to the n threads and then simultaneously executing the n threads, the document for the n pages A conversion task execution unit that simultaneously executes a format conversion task in parallel, and whenever any one of the n pages is converted through the conversion task execution unit, any one of the converted pages is rendered on the screen. However, if it is confirmed that the page immediately preceding any one of the converted pages has been converted and rendered first and is not displayed on the screen, the page in the previous order is converted and rendered and displayed on the screen. After waiting until the page in the previous order is converted and rendered and displayed on the screen, the display unit that renders any one page that has been converted and displays it on the screen and all of the n pages are converted. and a document file creation unit that generates a document file for a second electronic document of the second document format composed of the n pages that have been converted, when rendering is completed and displayed on the screen.

In addition, according to an embodiment of the present invention, a method of operating an electronic device that performs document format conversion based on parallel processing includes a first electronic document prepared in a first document format by a user - the first electronic document is n (n is is a natural number of 2 or more) pages.

Referring to FIG. 1 , an electronic device 110 according to an embodiment of the present invention includes a thread creation unit 111, a conversion task execution unit 112, a display unit 113, and a document file creation unit 114. .

The thread generator 111 converts a document file for a first electronic document prepared in a first document format from a user (the first electronic document is composed of n (n is a natural number equal to or greater than 2) pages) into a second document format. When a document format conversion command instructing conversion into a document file is applied, n threads for converting the document format of each of the n pages are generated.

Here, the first document format or the second document format may be a format of an extension such as 'docx', 'hwp', or 'pdf'.

Also, the thread refers to a unit of work that independently processes commands executed within a process.

When the n threads are created, the conversion task executor 112 assigns each of the n pages to the n threads, and then simultaneously executes the n threads, thereby generating a document for the n pages. Execute format conversion tasks concurrently in parallel.

The display unit 113, through the conversion task execution unit 112, whenever any one of the n pages is converted, renders the converted page and displays it on the screen, When it is confirmed that the page in the immediately previous sequence of any one of the pages has been converted and rendered first and is not displayed on the screen, the page waited until the page in the previous sequence has been converted and rendered and displayed on the screen. When the page of the previous order is converted and rendered and displayed on the screen, any one of the converted pages is rendered and displayed on the screen.

At this time, according to one embodiment of the present invention, the display unit 113, if it is confirmed that any one of the converted pages is the first sequential page among the n pages, the conversion and conversion of the previous sequential page Without checking whether the rendering is complete, any one of the converted pages may be immediately rendered and displayed on the screen.

When all of the n pages are converted and rendered and displayed on the screen, the document file generation unit 114 generates a document file for the second electronic document of the second document format composed of the n pages that have been converted. do.

Hereinafter, operations of the thread creation unit 111, the conversion task execution unit 112, the display unit 113, and the document file creation unit 114 will be described in detail with reference to FIGS. 2 and 3. do.

First, 'n=4' is assumed, and the first electronic document created in the first document format is 'Page 1 (201), Page 2 (202), Page 3 (203), Page 4 (204)' of four pages. Assume that it consists of

At this time, when a document format conversion command instructing the user to convert a document file for a first electronic document prepared in a first document format into a document file in a second document format is applied to the electronic device 110, the thread generator ( 111) may create four threads for converting the document format of each of the four pages, 'Page 1 (201), Page 2 (202), Page 3 (203), and Page 4 (204)'.

If the four threads are created as 'thread 1 (211), thread 2 (212), thread 3 (213), and thread 4 (214)' by the thread creation unit 111, the conversion operation is executed. As shown in FIG. 2, the unit 112 includes the four pages in the four threads 'thread 1 (211), thread 2 (212), thread 3 (213), and thread 4 (214)'. 'Page 1 (201), page 2 (202), page 3 (203), and page 4 (204)' may be assigned one by one.

After that, the conversion task executor 112 simultaneously executes the four threads 'Thread 1 (211), Thread 2 (212), Thread 3 (213), and Thread 4 (214)', thereby converting the four pages. A document format conversion operation for 'page 1 (201), page 2 (202), page 3 (203), and page 4 (204)' may be simultaneously executed in parallel.

At this time, the display unit 113, through the conversion task execution unit 112, selects one of the four pages 'Page 1 (201), Page 2 (202), Page 3 (203), and Page 4 (204)'. Whenever a page of is converted, any one of the converted pages is rendered and displayed on the screen, and the page in the order immediately preceding any one of the converted pages is converted and rendered first and displayed on the screen. If it is confirmed that the page in the previous order is converted and rendered and displayed on the screen, it waits until the page in the previous order is converted and rendered and displayed on the screen. One page can be rendered and displayed on the screen. However, if any one of the converted pages is 'Page 1 (201)', which is the first page among 'Page 1 (201), Page 2 (202), Page 3 (203), and Page 4 (204)' If confirmed, the display unit 113 may immediately render the converted 'Page 1 (201)' and display it on the screen without checking whether the conversion and rendering of the previous page have been completed.

In this regard, as shown by reference numeral 301, 'page 3 (203)', which is any one of 'page 1 (201), page 2 (202), page 3 (203), and page 4 (204)', is the most Assume that the conversion is completed first.

Then, the display unit 113 can check whether 'Page 2 (202)', which is a page immediately preceding the converted 'Page 3 (203)', has been converted and rendered first and is displayed on the screen. At this time, since 'Page 2 (202)' is a page that has not yet been converted and rendered, the display unit 113 does not render 'Page 3 (203)' and 'Page 2 (202)' First, it may wait until conversion and rendering are completed and displayed on the screen.

After that, as shown by reference numeral 302, when 'Page 2 (202)' is converted, the display unit 113 displays 'Page 1 (201)', which is the page immediately preceding the converted 'Page 2 (202)'. It can be checked whether the conversion and rendering are completed first and displayed on the screen. At this time, since 'Page 1 (201)' is a page that has not yet been converted and rendered, the display unit 113 does not render 'Page 2 (202)' and 'Page 1 (201)' First, it may wait until conversion and rendering are completed and displayed on the screen.

After that, as shown by reference numeral 303, when 'Page 1 (201)' is converted, the display unit 113 completes conversion and rendering of the previous page because 'Page 1 (201)' is the first page. Without checking whether or not, the converted 'Page 1 (201)' may be immediately rendered and displayed on the screen.

In this way, when 'Page 1 (201)' is rendered and displayed on the screen, the display unit 113 can then render and display 'Page 2 (202)' on the screen, which has been waiting, and then, 'Page 3 (203)' in progress can be rendered and displayed on the screen.

After that, as shown by reference numeral 304, when 'Page 4 (204)' is converted, the display unit 113 displays 'Page 3 (203)', which is the page immediately preceding the converted 'Page 4 (204)'. It can be checked whether the conversion and rendering are completed first and displayed on the screen. At this time, since 'Page 3 (203)' is a page that has already been converted and rendered and displayed on the screen, the display unit 113 can render 'Page 4 (204)' immediately and display it on the screen. there is.

In this way, when all of the four pages are converted and rendered by the display unit 113 and displayed on the screen, the document file generator 114 converts the four converted pages, 'page 1 (201), page 2 ( 202), page 3 (203), and page 4 (204)', a document file for the second electronic document of the second document format may be created.

According to an embodiment of the present invention, the electronic device 110 may further include a reference point page designation unit 115 , a occupancy calculation unit 116 , and a delay message display unit 117 .

When n, the number of pages constituting the first electronic document, exceeds a preset reference value, the reference point page specifying unit 115 determines the number obtained by rounding up a value obtained by multiplying n by a preset ratio among the n pages. Designate the page with as the base point page.

The occupancy calculation unit 116 checks the conversion completion time of the reference point page among the n pages through the conversion operation execution unit 112, and determines the conversion completion time of the reference point page among the n pages. If confirmed, occupancy rates occupied by pages that have been converted and rendered so far in all of the n pages and are being displayed on the screen are calculated.

When the delay message display unit 117 determines that the occupancy rate is equal to or less than a preset reference value, a conversion delay message notifying that conversion of the document format from the first document format to the second document format is delayed is generated and displayed on the screen. .

Hereinafter, operations of the reference point page designation unit 115, occupancy calculation unit 116, and delay message display unit 117 will be described in detail by way of example.

First, it is assumed that 'n=13' and that the first electronic document prepared in the first document format is composed of 13 pages 'Page 1, Page 2, Page 3, Page 4, ..., Page 13'. let's do it.

Then, when the number of pages constituting the first electronic document, 13, exceeds the preset reference value, the reference point page designation unit 115 rounds off a value obtained by multiplying 13 by a preset ratio among the 13 pages. A page with one sequence can be designated as the base point page.

Here, assuming that the preset reference value is '10' and the preset ratio is '0.5', the reference point page designation unit 115 sets the pages constituting the first electronic document to 'page 1, page 2, It can be confirmed that 13, which is the number of page 3, page 4, ..., page 13, exceeds the preset reference value of '10'.

Therefore, the reference point page specifying unit 115 sets a value obtained by multiplying 13 by '0.5', which is a preset ratio, among the 13 pages 'page 1, page 2, page 3, page 4, ..., page 13'. 'Page 7', which is a page having '7', which is an order number obtained by rounding up 6.5', may be designated as a reference point page.

After that, the occupancy calculation unit 116 checks the conversion completion time of the reference point page 'Page 7' through the conversion operation execution unit 112 among the 13 pages, and determines the reference point among the 13 pages. When the point at which conversion of page 'Page 7' is completed is confirmed, conversion and rendering have been completed in all of the 13 pages 'Page 1, Page 2, Page 3, Page 4, ..., Page 13' up to now. It is possible to calculate the occupancy rate occupied by the pages being displayed on the screen.

If it is assumed that the pages that have been converted and rendered so far and displayed on the screen are 'Page 1, Page 2, and Page 3', the occupancy calculation unit 116 calculates the occupancy by ' ' can be computed as

Then, the delay message display unit 117 notifies that the document format conversion from the first document format to the second document format is delayed when it is confirmed that the occupancy rate of '23.07 (%)' is less than a preset reference value. A delayed message can be created and displayed on the screen.

Here, when it is assumed that the preset reference value is '30.00 (%)', since it is confirmed that the occupancy rate of '23.07 (%)' is less than the preset reference value of '30.00 (%)', the delay message display unit 117 ) can generate the conversion delay message and display it on the screen.

That is, the electronic device 110 according to the present invention checks the rate at which conversion and rendering of pages have been completed up to now at the point in time when conversion of 'Page 7', which is the reference point page, is completed, so that the ratio is a predetermined reference value. If it is less than , the conversion delay message indicating that the format conversion operation for the electronic document is being delayed may be generated and displayed on the screen.

Through this, the user can intuitively grasp that the conversion of the document format from the first document format to the second document format is being delayed by checking the conversion delay message displayed on the screen.

According to an embodiment of the present invention, the electronic device 110 may further include a data checking unit 118, a reference vector generator 119, a cosine similarity calculating unit 120, and a task performance accuracy display unit 121. .

When a document file for the second electronic document is generated, the data checking unit 118 checks the data size of each of the n pages of the first electronic document, and the n pages of the second electronic document. Check the data size for each of them.

The reference vector generator 119 generates an n-dimensional first reference vector having a data size of each of the n pages of the first electronic document as a component, and the n pages of the second electronic document An n-dimensional second reference vector having each data size as a component is generated.

The cosine similarity calculation unit 120 calculates the cosine similarity between the n-dimensional first reference vector and the n-dimensional second reference vector.

Here, the cosine similarity between the n-dimensional first reference vector and the n-dimensional second reference vector may be calculated according to Equation 1 below.

Here, S is the cosine similarity between vectors A and B. It has a value between -1 and 1, and the larger the value, the more similar the vector, A _i is the i-th component of vector A, and B _i is the i of vector B. means the second component.

The task performance accuracy display unit 121 displays the cosine similarity on the screen as information representing task performance accuracy for a document format conversion task from a document file for the first electronic document to a document file for the second electronic document. display on

Hereinafter, operations of the data verification unit 118, the reference vector generator 119, the cosine similarity calculator 120, and the task performance accuracy display unit 121 will be described in detail, for example.

First, as in the above example, 'n=4' is assumed, and the first electronic document created in the first document format has four pages 'Page 1 (201), Page 2 (202), Page 3 (203), It is said to be composed of 'page 4 (204)', and the four pages converted by the document file generation unit 114 are 'page 1 (201), page 2 (202), page 3 (203), and page 4 ( 204)', it is assumed that a document file for a second electronic document in a second document format is created.

Then, the data checking unit 118 may check the data size of each of the four pages of the first electronic document and the data size of each of the four pages of the second electronic document.

If, by the data confirmation unit 118, the data size for each of 'page 1 (201), page 2 (202), page 3 (203), and page 4 (204)' of the first electronic document is '2 ( kB), 3 (kB), 5 (kB), 10 (kB)', and the converted 'page 1 (201), page 2 (202), page 3 (203), When it is determined that the data size for each of page 4 (204) is '1 (kB), 6 (kB), 2 (kB), and 7 (kB)', the reference vector generator 119 generates the first The data size for each of 'page 1 (201), page 2 (202), page 3 (203), and page 4 (204)' of the electronic document '2 (kB), 3 (kB), 5 (kB), A 4-dimensional first reference vector having 10 (kB)' as a component is generated as '[2 3 5 10]', and the converted 'page 1 (201), page 2 (202) of the second electronic document , page 3 (203), page 4 (204), respectively, the data size of '1 (kB), 6 (kB), 2 (kB), 7 (kB)' as a component of the 4-dimensional second criterion You can create a vector like '[1 6 2 7]'.

After that, the cosine similarity calculation unit 120 determines the cosine similarity between the 4-dimensional first reference vector '[2 3 5 10]' and the 4-dimensional second reference vector '[1 6 2 7]'. According to Equation 1 above, it can be calculated as '0.898'.

Then, the task performance accuracy display unit 121 converts the cosine similarity of '0.898' to the task performance accuracy for a document format conversion task from a document file for the first electronic document to a document file for the second electronic document. It can be displayed on the screen as information representing .

That is, the electronic device 110 according to the present invention compares the similarity between the size of the pages constituting the electronic document before format conversion and the size of pages constituting the electronic document after format conversion, so that the accuracy of performing the format conversion operation is determined to some extent. is displayed on the screen, it is possible to support the user to intuitively grasp with what degree of accuracy the format conversion operation has been performed.
