1 is a diagram showing the structure of an electronic device that converts an electronic document into a knowledge data document according to an embodiment of the present invention.

Referring to FIG. 1 , an electronic device 110 according to the present invention includes a web document conversion unit 111, an important keyword selection unit 112, an object confirmation unit 113, a summary generation unit 114, and a conversion processing unit 115. ).

When a command for converting an electronic document into a knowledge data document is received from a user, the web document conversion unit 111 converts the electronic document into a web document having a format based on a markup language.

Here, the markup language refers to one of languages that specify the structure of documents or data using tags or the like, and includes HyperText Markup Language (HTML) and Extensible Markup Language (XML).

When the electronic document is converted into the web document, the important keyword selection unit 112 parses the markup language code constituting the web document, and among the words included in the web document, After extracting n words (where n is a natural number equal to or greater than 2) in order of frequency of occurrence, the n words are selected as important keywords for the web document.

For example, when the words included in the web document are '100' and n is '5', the important keyword selection unit 112 appears in the web document among the 100 words included in the web document. After extracting 5 words in the order of the highest frequency, the extracted 5 words can be selected as important keywords for the web document.

In this case, according to an embodiment of the present invention, the electronic device 110 may further include a feature vector generator 116 and a group allocator 117.

When the n words are selected as the important keywords, the feature vector generator 116 calculates the frequency of occurrence of each of the n words in the web document and the character of each of the n words in the web document. After calculating the average value of the size, a feature vector corresponding to each of the n words is generated by constructing a 2D vector having the number of occurrences and the average value as components for each of the n words.

For example, as in the above example, let n be '5', and the five words selected as the important keywords in the important keyword selection unit 112 are 'red', 'orange', 'yellow', 'green', ' 'blue', and the frequency of each occurrence of the words 'red', 'orange', 'yellow', 'green', and 'blue' in the web document is '20', '30', and '10'. ', '40 times', '50 times', the feature vector generator 116 uses the words 'red', 'orange', 'yellow', 'green', and 'blue' in the web document. For each frequency of appearance, the frequency of appearance of red is '20', the frequency of orange is '30', the frequency of yellow is '10', the frequency of green is '40', You can check the frequency of appearance of blue as '50 times'.

Also, the feature vector generator 116 may calculate an average value of the font size of each of the words 'red', 'orange', 'yellow', 'green', and 'blue' in the web document. . In relation to this, the word 'red' appears '20 times' in the web document, '10 times' has a font size of '12pt', and the remaining '10 times' has a font size of '14pt'. In this case, the feature vector generator 116 may calculate the average value of the font size of the word 'red' in the web document as '13pt'. In this way, the feature vector generator 116 can calculate the average value of the font size in the web document for each of the words 'orange', 'yellow', 'green', and 'blue'. .

If the average value of the font size in the web document for each of the words 'red', 'orange', 'yellow', 'green', and 'blue' is '13pt', '12pt', '16pt', Assuming that '14pt' and '14pt' are calculated, each of the words 'red', 'orange', 'yellow', 'green', and 'blue' calculated by the feature vector generator 116 is displayed on the web. The frequency of appearance in the document and the average value of the font size can be shown in Table 1 below.

word frequency of occurrence of the word Average value of word size Red 20 times 13pt Orange 30 times 12pt yellow 10 times 16pt green 40 times 14pt blue 50 times 14pt

In this way, when the frequency and average value of the words 'red', 'orange', 'yellow', 'green', and 'blue' are calculated as shown in Table 1, the feature vector generator 116 calculates 'red', For each of 'orange', 'yellow', 'green', and 'blue', a feature vector corresponding to each word can be generated by constructing a two-dimensional vector having the appearance frequency and the average value as components. .

In this regard, the feature vector generator 116 may generate a feature vector corresponding to the word 'red' as '[20 13]'. In this way, the feature vector generator 116 may generate feature vectors corresponding to the remaining words 'orange', 'yellow', 'green', and 'blue'.

The group allocator 117 performs K-means clustering based on feature vectors corresponding to each of the n words, clusters the n words into K groups, and Among the groups, words belonging to the same group are designated as words having similar importance, and then group information about the group to which each word belongs is assigned to each of the n words.

Here, K-means clustering refers to an algorithm that groups data composed of a vector form into K groups, and clusters data into K groups so that the difference between the center of the group to which the data belongs and the distance between each data is minimized. It is an algorithm.

In this regard, as in the above example, assuming that five words 'red', 'orange', 'yellow', 'green', and 'blue' are extracted as important keywords, and K is '3', The group allocator 117 performs K-means clustering based on the feature vectors of each of the five words 'red', 'orange', 'yellow', 'green', and 'blue', The five words 'orange', 'yellow', 'green', and 'blue' can be clustered into three groups.

At this time, since the group assigning unit 117 clusters the n words into K groups based on a feature vector composed of the average value of the frequency of occurrence of words and the average value of the letter size, the n words have a high frequency of occurrence of words. It can be clustered into a group with a high mean value of font size, a group with a medium frequency of occurrence of words and an average value of average font size, and a group with a low average value of font size with low frequency of occurrence of words.

In this way, as a result of clustering the five words 'red', 'orange', 'yellow', 'green', and 'blue' into three groups by the group assignment unit 117, 'red' and 'orange' ' is clustered as 'Group 1', the words 'green' and 'blue' are clustered as 'Group 2', and the word 'yellow' is clustered as 'Group 3'. The unit 117 designates the words 'red' and 'orange' belonging to 'group 1' of the three groups as words having similar importance to each other, and designates words belonging to 'group 2' of the three groups. The words 'green' and 'blue' may be designated as words having similar importance, and the word 'yellow' belonging to 'group 3' among the three groups may be designated as words having similar importance.

Then, the group allocator 117 may allocate group information about 'Group 1' to which the word 'red' belongs to the word 'red', and may allocate 'group 1' to the word 'orange'. Group information for 'Group 1' to which the word 'orange' belongs can be assigned, and group information for 'Group 3' to which the word 'yellow' belongs can be assigned to the word 'yellow'. For the word 'green', it is possible to assign group information for 'group 2' to which the word 'green' belongs, and for the word 'blue' to which the word 'blue' belongs. Group information for 'Group 2' can be assigned.

The object identification unit 113 parses the markup language code constituting the web document to check whether an object is inserted into the web document, and if it is confirmed that a plurality of objects are inserted into the web document, the plurality of objects are inserted into the web document. The type of each of the objects and the insertion position of each of the plurality of objects in the web document are checked.

Here, an object means an item other than text such as a figure, image, table, etc. that can be inserted into a document, and the type of object means information indicating which type of table, figure, or image the corresponding object corresponds to, The insertion position refers to coordinate information indicating at which position a specific object is inserted in the web document.

The summary sentence generation unit 114 parses the markup language code constituting the web document to identify sentences included in the web document, and then includes at least one n word among the sentences included in the web document. A summary sentence is generated by selecting one sentence and arranging the at least one sentence according to an arrangement order in the web document.

For example, as in the above example, when it is assumed that five words, 'red', 'orange', 'yellow', 'green', and 'blue' are selected as the important keywords, the summary sentence generating unit 114 Among the sentences included in the web document, at least one sentence including at least one of five words 'red', 'orange', 'yellow', 'green', and 'blue' may be extracted.

At this time, when it is assumed that 30 sentences are extracted as the at least one sentence, the summary sentence generation unit 114 generates a summary sentence by sequentially arranging the at least one sentence, 30 sentences, according to the arrangement order in the web document. can do.

In this way, when the important keyword is selected from the web document, the type and insertion position of each of the plurality of entities are confirmed, and the generation of the summary is completed, the conversion processing unit 115 converts the main text constituting the web document. Generates a knowledge data document file based on JSON (JavaScript Object Notation) format including data for the key words, data for the important keywords, data for the type and insertion position of each of the plurality of entities, and data for the summary.

JSON (JavaScript Object Notation) is a human-readable text format used to convey data objects consisting of attribute-value pairs and array data types (or any other serializable value) or key-value pairs. Refers to the open standard format used. JSON is a data format used by a server to transmit data to a client. It is widely used recently because it is a lightweight data format that can express data in a simpler and unified form than the existing XML format data transmission method. Normally, when a server transmits a JSON format-based file to a client, the client opens the JSON format file through a browser, and renders and displays an object on the screen.

At this time, according to one embodiment of the present invention, the conversion processing unit 115 may generate the JSON format-based knowledge data document file as a file having an extension of '.vd' (virtual document).

At this time, according to an embodiment of the present invention, the electronic device 110 further includes a division unit 118, a text display unit 119, an important keyword display unit 120, an object information display unit 121, and a summary display unit 122. can include

It is divided into keyword display area, object information display area, and summary display area.

In this regard, when an execution command for the knowledge data document file is applied from the user, the division unit 122 converts the screen display area into a text display area 211 and an important keyword display area 212 as shown in FIG. 2 . ), an object information display area 213 and a summary display area 214.

At this time, according to an embodiment of the present invention, when an execution command of the knowledge data document file is applied from the user, the electronic device 110 opens the browser installed in the electronic device 110 or the knowledge data document file. Information according to the execution of the knowledge data document file may be displayed on the screen by executing a dedicated viewer for display. At this time, when the conversion processing unit 115 generates the knowledge data document file, the screen display area in the knowledge data document file includes a body display area 211, an important keyword display area 212, and an entity information display area 213 And code related to predetermined layout setting information to be divided and displayed in the summary display area 214 can be inserted. Through this, the division unit 118, when an execution command of the knowledge data document file is applied from the user, parses the code related to the layout setting information, thereby changing the screen display area to the text display area 211 and displaying important keywords. It can be divided into an area 212, an entity information display area 213, and a summary display area 214.

The body display unit 119 parses data for the body constituting the web document included in the knowledge data document file, and displays the body constituting the web document in the body display area 211 .

The important keyword display unit 120 parses data on the important keywords included in the knowledge data document file, classifies and displays the n words according to the K groups in the important keyword display area 212, and at the same time , A first notification message notifying that the n words are important keywords for the document and a second notification message notifying that words belonging to the same group among the K groups are words having similar importance to each other are generated, and the important keyword display area ( 212).

For example, as in the above example, the words 'red', 'orange', 'yellow', 'green', and 'blue' were selected as important keywords, and the words 'red' and 'orange' were selected as 'group'. 1', the words 'green' and 'blue' are clustered in 'group 2', and the word 'yellow' is clustered in 'group 3', the important keyword display unit 120 displays 'red' ', 'orange', 'yellow', 'green', and 'blue' can be divided into three groups and displayed in the important keyword display area 212 .

In addition, the important keyword display unit 120 is the same as the first notification message informing that the words 'red', 'orange', 'yellow', 'green', and 'blue' are important keywords for the document and the three groups. A second notification message notifying that words belonging to the group are words having similar importance may be generated and displayed on the important keyword display area 212 . In this regard, the second notification message indicates that the words 'red' and 'orange' belonging to 'group 1' among the three groups are words having similar importance, and 'green' belonging to 'group 2'. ', 'blue' may indicate that the words have similar importance to each other, and may contain information indicating that the word 'yellow' belonging to 'group 3' has similar importance to each other.

The entity information display unit 121 parses data on the type and insertion position of each of the plurality of entities included in the knowledge data document file, and displays the type of each of the plurality of entities in the entity information display area 213. and information about the insertion position in the web document are displayed in correspondence with each entity.

For example, if 'object 1' among the plurality of objects exists, the type of 'object 1' is 'figure', and the insertion position of 'object 1' in the web document is 'coordinate 1', The object information display unit 121 displays the object information display area 213 in correspondence with the type of 'object 1' being 'figure' and the insertion position of 'object 1' in the web document being 'coordinate 1'. can

The summary display unit 122 parses data on the summary included in the knowledge data document file and displays the summary in the summary display area 214 .

That is, when a command for converting a predetermined electronic document into a knowledge data document is applied from the user, the electronic device 110 according to the present invention converts the electronic document into a web document having a markup language-based format and then After selecting important keywords in the web document, checking information on objects inserted into the web document, and generating a summary of the web document, the body of the web document, the important keywords, information on the objects and A JSON format-based knowledge data document file including data for the summary may be generated, and when the knowledge data document file is later executed by a user, the body of the document, the important keywords, information of the entities, and By displaying the summary on one screen, it is possible to support the user to check various information about the electronic document at a glance.

According to an embodiment of the present invention, the electronic device 110 is configured to enable security settings for the knowledge data document file, and includes a table maintenance unit 123, a connection number generation unit 124, and an encryption key extraction. A unit 125, a file encryption unit 136, and a guide message display unit 127 may be further included.

The table maintenance unit 123 stores and maintains a table in which predetermined t (t is a natural number of 2 or more) encryption keys and integers of 0 or more and t-1 or less corresponding to each encryption key are recorded.

For example, assuming that t is '5', the table maintenance unit 123 may store and maintain an encryption key table as shown in Table 2 below.

5 encryption keys integer value encryption key 1 0 encryption key 2 One encryption key 3 2 encryption key 4 3 encryption key 5 4

After the knowledge data document file is generated, the connection number generator 124 generates a numerical value indicating the number of words included in each of the K groups when a security setting command for the knowledge data document file is received from the user. Concatenation is performed in ascending order to generate a concatenated number.

For example, as in the above example, five words 'red', 'orange', 'yellow', 'green', and 'blue' are 'group 1' including the words 'red' and 'orange'. , If it is assumed that it is classified into 'Group 2' including the words 'green' and 'blue' and 'Group 3' including the word 'yellow', the connection number generator 124 includes 'Group 1 '2', the number of words 'red' and 'orange' included in ', '2', the number of words 'green' and 'blue' included in 'group 2', 'group 3' By extracting a numerical value representing '1', which is the number of words 'yellow' included in ', and concatenating numerical values representing the number of words included in each of the three extracted groups in ascending order, '221' is obtained. You can generate a link number.

When the concatenated number is generated, the encryption key extraction unit 125 calculates an operation value by performing a modulo operation with the concatenated number as the dividend and the t as the divisor, and calculates the operation value from the table. A first encryption key corresponding to is extracted.

Here, the modulo operation refers to an operation of calculating a remainder by performing division by dividing a dividend by a divisor.

For example, as in the above example, assuming that t is '5' and the concatenated number is '221', the encryption key extraction unit 125 takes the concatenated number '221' as the dividend and the '5' By performing a modulo operation with ' as a divisor, the operation value may be calculated as '1'.

Then, the encryption key extraction unit 125 may extract 'encryption key 2' as the first encryption key corresponding to the operation value '1' from the table such as Table 2 above.

The file encryption unit 126 encrypts the knowledge data document file with the first encryption key.

For example, as in the above example, when 'encryption key 2' is extracted as the first encryption key through the encryption extraction unit 125, the file encryption unit 126 converts the knowledge data document file into the first encryption key. It can be encrypted with 'encryption key 2'.

When the knowledge data document file is encrypted, the guide message display unit 127 displays a guide message indicating that the connection number is a security code for decryption of the knowledge data document file on the screen.

At this time, the user may read the guide message and be familiar with the security code displayed on the screen in order to perform decryption of the knowledge data document file later.

At this time, according to an embodiment of the present invention, the electronic device 110 may further include a security code input message display unit 128 and a decryption unit 129.

The security code input message display unit 128 instructs the user to input the security code for security release when a security release command for the knowledge data document file is received from the user after encryption of the knowledge data document file is completed. Security code input message is displayed on the screen.

For example, when a security release command for the knowledge data document file is received from the user, the security code input message display unit 128 displays a security code input window along with a security code input message to the user, 'Please enter a security code'. can be displayed on the

At this time, when the concatenated number is received from the user in response to the security code input message, the decoder 129 performs a modulo operation with the concatenated number as the dividend and the t as the divisor, thereby obtaining the calculated value is calculated, the first encryption key corresponding to the operation value is extracted from the table, and the knowledge data document file is decrypted with the first encryption key.

For example, as in the above example, assuming that t is '5' and the concatenated number is '221', the decoder 129 receives the concatenated number '221' from the user as a security code, An operation value of '1' may be calculated by performing a modulo operation with the concatenated number '221' as the dividend and '5' as the divisor.

Then, the decryption unit 129 extracts 'encryption key 2' as the first encryption key corresponding to the operation value '1' from the table as shown in Table 2, and then uses 'encryption key 2' as the knowledge data document file. can decrypt.

3 is a flowchart illustrating an operating method of an electronic device for converting an electronic document into a knowledge data document according to an embodiment of the present invention.

In step S310, when a command for converting an electronic document into a knowledge data document is received from a user, the electronic document is converted into a web document having a markup language-based format.

In step S320, when the electronic document is converted into the web document, the markup language code constituting the web document is parsed, and among the words included in the web document, the order of occurrence frequency in the web document is increased. After extracting n (n is a natural number equal to or greater than 2) words, the n words are selected as important keywords for the web document.

In step S330, it is checked whether an object is inserted into the web document by parsing the markup language code constituting the web document, and if it is confirmed that a plurality of objects are inserted into the web document, the plurality of objects The type of each object and the insertion position of each of the plurality of objects in the web document are checked.

In step S340, after parsing the markup language code constituting the web document to check the sentences included in the web document, at least one of the sentences included in the web document includes one or more of the n words. A summary sentence is generated by selecting sentences and arranging the at least one sentence according to an arrangement order in the web document.

In step S350, JSON format-based data including data on the body constituting the web document, data on the important keywords, data on the type and insertion position of each of the plurality of entities, and data on the summary sentence Generate knowledge data document files.
