By the way, in the case of content created and posted by general users other than service management organizations such as blogs, text data and image data may be quoted from other web pages. Of course, there is no problem if the quotation has legality, but it is often difficult for general users to judge the legality of the quotation and the copyright infringement. Therefore, even if the user has no malicious intent, as a result, inappropriate quoting may occur.
For that purpose, if it is not strictly determined whether it is a legal citation, in order to prevent the risk of copyright infringement, it is necessary to automatically determine the citation when creating the content. Is desirable. However, it is not desirable for the blog service system and the usability for the blog service system and the user to check the quotation with a huge amount of website data and increase the processing time for the determination.

  Therefore, in the present invention, when the user is properly guided about quoting, the user does not feel inconvenience such as an increase in waiting time for determination, and the processing load of the system is not significantly increased. The purpose is to do.

The information processing apparatus according to the present invention includes a determination opportunity detection unit that detects that a paste operation is detected during content creation in a terminal device and that a determination opportunity regarding citation is generated with the paste portion as a determination target; In response to the detection opportunity being detected by the detection unit, the web page data indicated by the browsing history information in the terminal device is searched during the creation of the content, and the same data as the determination target portion exists. A first citation appropriateness determination unit that performs processing for confirming whether or not to perform, and acquires information of a web page in which the same data as the determination target portion exists as source information, and the first citation appropriateness determination A process for determining whether or not the source information acquired by the department is described in the content, and the total text amount of the content A process of determining whether the ratio of the amount of text of the determination target or the ratio of the image data of the determination target to the total display surface is equal to or more than a predetermined threshold, and the character attribute of the text of the determination target is the content of the content. A second quotation propriety determination unit that performs processing for determining whether the text is different from the text other than the determination target at the timing of the upload request for the content from the terminal device , the determination result of the first quotation propriety determination unit, and the The terminal device further includes a caution unit that performs a process of displaying a caution display in the terminal device according to the determination result of the second quotation adequacy determination unit.
The content is assumed to be a blog article, for example. Although such content is created and uploaded by the user, text data and image data of other content may be included as it is during the creation. It is often difficult for the user to determine whether this is appropriate as a citation. If a determination opportunity is detected, a determination using the browsing history information is performed as the first citation determination. In addition, when the upload request is made, a determination using a predetermined determination criterion is performed as the second quotation adequacy determination. In this way, the suitability of citation is determined, and the user is alerted if necessary.

In the above-described information processing device, the alerting unit is a part of the data in the web page in which the data portion related to the paste operation by the first quotation adequacy determining unit has the same data as the determination target portion. When it is determined that the amount is not equal to a part, when the second citation appropriateness determination unit determines that the source information is not described in the content, the second citation appropriateness determination unit When it is determined that the proportion of the portion to be determined is equal to or more than the threshold value, or by the second quotation adequacy determining unit, the character attribute of the portion to be determined is other than the determination target of the content. If it is determined not be different from the body, in response to fall under any Note 喚 including guide information to a proper citation is set for each determination Create a message performs a process of displaying on the terminal device.
Guide information for proper citation is, for example, information for assisting in citations, a message recommending deletion of a part of the paste part or addition of blog text, presentation of models such as citations and description modes, etc. is there.

In the above-described information processing device, the determination opportunity detection unit detects a paste operation in the content being created, thereby detecting the determination opportunity for the paste portion .
The quoted portion is usually inserted into the content being created by a copy and paste operation of text data or image data. Therefore, when there is a paste operation, the first citation appropriateness determination is made on the assumption that the citation may have been made.

In the above-described information processing device, it is conceivable that the determination opportunity detection unit detects a paste operation with a predetermined number of characters or more in the content being created, and thus detects the determination operation as to the paste portion.
That is, in the case of a small number of characters in the character data, for example, in the case of an operation of copying and pasting a small number of characters such as less than 10 characters, the quoted portion is not estimated.

In the above-described information processing device, the determination opportunity detection unit displays a stylistic analysis result for the text data input in the content being created, and a stylistic analysis result for another sentence created by the content creator. It is conceivable that the similarity is determined by comparison, and if the similarity cannot be confirmed, it is possible to detect that a determination opportunity regarding citation has occurred with the portion of the input text data as the determination target .
In other words, the quoted part is estimated from the difference in wording. For example, referring to the user's past post, the characteristics of the user writing style are specified by morphological analysis, and the portion other than the user writing style in the article is set as the quoted portion.

In the above-described information processing device, the first quotation adequacy determining unit searches the web page data indicated by the browsing history information and confirms whether or not the same data as the portion estimated to be the quotation exists. At the same time, the information of the web page in which the same data exists is acquired as the source information .
That is, the copy source of the text data or the image data is searched from the web page data indicated by the browsing history information, and for the web page in which the same data exists, for example, the URL of the web page, the website name, the information of the web page manager, etc. As source information .

In the information processing apparatus described above, the first quotation propriety determination unit searches the web page data extracted by the browsing time condition from the web page data indicated by the browsing history information, and finds the portion estimated to be a quotation. It is conceivable to perform a process of confirming whether the same data as above exists.
That is, not all of the browsing history information, but the copy source of the text data or the image data is searched for from the web page data corresponding to the browsing time condition such as within the latest predetermined time or after the start of blog creation.

In the above-described information processing device, the second quotation appropriateness determination unit performs a process of determining whether or not the source information acquired by the first quotation appropriateness determination unit is described in the content .
That is, it is confirmed whether or not the source (citation source) is described for the portion estimated to be cited.

In the information processing apparatus described above, the second quotation adequacy determining unit determines whether the ratio of the determination target text amount to the total text amount of the content or the ratio of the determination target image data to the total display surface is equal to or greater than a predetermined threshold. Processing for determining whether or not there is is performed .
That is, the amount of the quoted part and the amount of the text are compared.

In the above-described information processing device, the second quotation adequacy determining unit performs a process of determining whether or not the character attribute of the text to be determined is different from the body of the content other than the determination target .
That is, it is judged whether the portion estimated to be quoted is described in a manner clearly different from the text.

It is conceivable that the information processing apparatus described above includes a citation notifying unit that performs a process of notifying the citation source that the citation has been performed , based on the citation information acquired by the first citation appropriateness determination unit .
For example, when there is a portion estimated to be a citation, the citation source is notified that the citation is performed.

An information processing method of the information processing apparatus according to the present invention is carried out, by the detected paste operation is in content creation in the terminal device, the determination chance detection step of detecting a determination opportunities for citing paste portions as determination target has occurred And, in response to the determination opportunity being detected by the determination opportunity detection step, while the content is being created, the web page data indicated by the browsing history information in the terminal device is searched, and the portion that is the determination target is searched. a first reference appropriateness determination step of acquiring and executes a process of confirming whether the same data is present, the information of the web page that the determination target portion in the same data exists as the source information and the It is determined whether the source information acquired in the first citation appropriateness determination step is described in the content. And a process of determining whether the ratio of the determination target text amount to the total text amount of the content or the ratio of the determination target image data to the total display surface is a predetermined threshold value or more, A second citation suitability determination step of performing a process of determining whether or not a character attribute of the target text is different from a body of the content other than the determination target at a timing of an upload request of the content from the terminal device ; According to the determination result of the first quotation propriety determination step and the determination result of the second quotation propriety determination step, a caution calling step for performing a process of causing the terminal device to perform the caution display is performed.
As a result, content quoting is distributed and performed during creation and upload.
A program according to the present invention is a program that causes an information processing apparatus to execute the processing of this information processing method.
A storage medium according to the present invention is a storage medium storing the above program.
This program and storage medium facilitate the implementation and provision of the information processing apparatus of the present invention.

  According to the present invention, the first quotation adequacy determination is performed during the creation of content such as a blog article, so that it is possible to prevent the user from feeling these processing times. For example, the process of searching for a copy source using a browsing history, which is expected to take a long time, and whether or not the copy part is a part of the copy source, is the first quotation adequacy determination, and is a time burden. Can be executed without calling the user. Further, in the second quotation adequacy determination, useless determination does not occur because the quotation eligibility is determined in the state where the content is completed. As a result, an appropriate reminder regarding citation can be executed without causing a user to feel a time burden and without causing a significant increase in processing load on the system.

  FIG. 2 shows the hardware configuration of the information processing apparatus that constitutes the blog server 1 and the user terminal 5 shown in FIG. Each of the devices shown as the blog server 1 and the user terminal 5 is realized by a computer device capable of information processing and information communication as shown in FIG.

In FIG. 2, a CPU (Central Processing Unit) 101 of a computer device is provided with various types of programs according to a program stored in a ROM (Read Only Memory) 102 or a program loaded from a storage unit 108 into a RAM (Random Access Memory) 103. Execute the process. The RAM 103 also appropriately stores data necessary for the CPU 101 to execute various processes.
The CPU 101, the ROM 102, and the RAM 103 are connected to each other via a bus 104. An input / output interface 105 is also connected to the bus 104.
An input unit 106, an output unit 107, a storage unit 108, and a communication unit 109 are connected to the input / output interface 105.
The input unit 106 includes a keyboard, a mouse, a touch panel and the like.

By the CPU 101 performing processing operations based on various programs, necessary information processing and communication as the blog server 1 and the user terminal 5 are executed.
It should be noted that the information processing device configuring the blog server 1 and the user terminal 5 is not limited to a single computer device as shown in FIG. 2, and may be configured by systematizing a plurality of computer devices. .. The plurality of computer devices may be systematized by a LAN or the like, or may be arranged at a remote place by a VPN or the like using the Internet or the like. The plurality of information processing devices may include an information processing device as a server group (cloud) that can be used by a cloud computing service.

<2. Blog server and database>
FIG. 3 shows a functional configuration of the blog server 1 including one or a plurality of information processing devices and various DBs.
Each function as the blog server 1 is a function realized by a process executed by the CPU 101 in the information processing apparatus according to a program. However, the processing of all or part of each configuration described below may be realized by hardware.
Further, when each function is realized by software, each function does not need to be realized by an independent program. Processing of a plurality of functions may be executed by one program, or one function may be realized by cooperation of a plurality of program modules.
Further, each function may be distributed to a plurality of information processing devices. Further, one of the functions may be realized by a plurality of information processing devices.

  The blog server 1 has functions as a blog management unit 11, a determination opportunity detection unit 12, a first citation appropriateness determination unit 13, a second citation appropriateness determination unit 14, an alerting unit 15, and a citation notification unit 16 as illustrated. .

The blog management unit 11 executes processing necessary as a server that provides a blog service. For example, it provides a blog environment to users, manages information of users as bloggers, manages storage of created blogs, manages information about each blog, and delivers web pages of blogs (articles) according to access requests.
In addition, the blog management unit 11 sequentially updates and reads information in the management DB 53.

The determination opportunity detection unit 12 detects that an opportunity to determine a citation has occurred while creating a blog article in the user device 5. That is, it is detected by some method that a portion estimated to be possible to be cited has occurred.
It should be noted that detecting the occurrence of an opportunity to make a decision regarding citation does not mean determining whether or not it is actually a citation. Therefore, it is possible to perform a simple process such as detecting that a determination opportunity has occurred due to a paste operation on the user terminal 5, for example.

In order to detect the operation on the user terminal 5 on the blog server 1, it is conceivable that, for example, the blog creation web page provided to the user terminal 5 includes a program for detecting and transmitting the user operation. .
The data of a web page forming a blog article page or a blog creation page is a structured document file such as HTML (HyperText Markup Language) or XHTML (Extensible HyperText Markup Language). Then, in this structured document file, the text data of the article created by the blogger and the designation information of the image, as well as the layout and display mode (character color, font, size, decoration, etc.) of them are described.
By embedding a program generated in a programming language such as Java (registered trademark) or a script language such as JavaScript (registered trademark) that can operate on a browser basis in such web page data, various processes can be performed by the user. It can be executed by the terminal 5 (browser). As a result, for example, when the user is creating a blog article, it is possible to monitor the user's operation, the data being edited, etc. on the blog server 1 side, and, for example, a judgment opportunity corresponding to the user's operation or the like. Detection can be performed.

When the blog article is being created in the user terminal 5, the first citation appropriateness determination unit 13 responds to the determination opportunity detection unit 12 detecting a determination opportunity for citation, and accordingly, the browsing history of the user terminal 5. A citation suitability determination (first citation suitability determination) using information is performed.
As the first quotation adequacy determination, for example, the same content as the paste location (copy location) is searched retroactively along the browsing history of the user. Also, the ratio of the copy location in the content of the web page of the copy source is calculated.

The second quotation adequacy determination unit 14 performs a quotation adequacy determination (second quotation adequacy determination) using the determination criterion set at the timing of the blog article upload request from the user terminal 5.
As the second quotation adequacy determination, for example, it is determined whether or not the paste portion is in a “subordinate range” with respect to the main article portion, and whether or not the quotation source is presented is confirmed.

The alerting unit 15 performs processing for alerting the user terminal 5 according to the determination result of the first quotation appropriateness determining unit 13 and the determination result of the second quote appropriateness determining unit 14.
For example, when either the first or second citation appropriateness determination unit determines that there is a possibility of inappropriate citation or unauthorized reprinting, warning of inappropriate citation is issued without starting uploading of article. Is assumed.

  The citation notifying unit 16 performs a process of notifying the source that the citation is performed. In some cases, a notification may be received from the user who is the source of the request, and necessary processing may be performed.

In FIG. 3, a blog DB 51, an image DB 52, and a management DB 53 are shown as DBs accessed by the blog server 1.
The blog DB 51 is a DB that stores blog data about each blogger. The web page data of each blog is saved, and articles are added to each blog according to the posts of bloggers.
Viewers can also post comments on the blog. The comment data from such a viewer is also stored in the blog DB 51 in association with the blog or individual articles in the blog.
When there is an access request for a certain blog from the user terminal 5, the blog server 1 reads the requested blog page from the blog DB 51 and delivers it to the user terminal 5.

The image DB 52 is a DB that stores image data (still image data or moving image data) attached to a blog.
Images can be attached to the articles in the blog. For example, the blog DB 51 stores article data and image designation information (link information) corresponding to the article data. Then, the image data itself is stored in the image DB 52.
In the case of a request for access to a blog article to which an image is attached, the web page data is displayed by the browser on the user terminal 5. At that time, the user terminal 5 sends the image data to the blog server 1 by the link setting on the web page. To request. The blog server 1 reads the image data from the image DB 52 in response to the request and delivers it to the user terminal 5. As a result, the blog article with the image is displayed on the user terminal 5.
Note that this is an example, and web page data including image data may be stored in advance in the blog DB 51.

The management DB 53 is a DB that stores information for managing each blog.
For example, a blog ID (Identification) is set for one blog, and accompanying information is managed by the blog ID. For example, for each blog (blog ID), user information, blog management information, blog performance information, size information, etc. are managed while being sequentially updated.

The user information is information on a user (blog administrator) as a blogger who has opened a blog. For example, the user information includes a user ID, a login password as an administrator, attribute information such as a user's address, name, and age, login date and time as an administrator, and the like.
The blog management information is attribute information of the blog itself. For example, the URL of the blog, the genre information of the blog, the opening date and time of the blog, the number of articles included in the blog, the update date and time information, the layout information of the blog, the link setting information and the like are included.
The blog performance information includes the total number of page views, the number of unique users who have accessed, the total number of backlinks, the total number of comments, the page rank of the blog, the number of clicks on advertisements, etc. These are sequentially updated.
The size information is information on the data size of the entire blog. Further, the size information of each article may be stored. The size information is updated as the blog is updated.

Each of the above DBs (blog DB 51, image DB 52, management DB 53) may be implemented in any form as long as the blog server 1 is accessible. For example, all of the DBs may be formed in the storage unit in the same system as the blog server 1, or a part or all of the DBs may be provided separately or in a computer system such as a remote place. Of course, each DB does not have to be formed in one device (for example, one HDD or the like). Further, each DB does not need to be configured as one DB. For example, the information stored as the management DB 53 may be stored and managed by a plurality of DBs (for example, a user management DB relating to blogs and a blog management DB). Each of the above DBs is merely an example of a storage unit of information related to the processing of the embodiment in the form of one DB.

<3. First Embodiment>
The processing of the blog server 1 as the first embodiment will be described.
The blog server 1 transmits a web page for creating a blog to the user terminal 5, and in the case where the user is creating the blog, whether or not the citation is appropriate according to the possibility of citation being detected. In addition to the above determination, the quotation adequacy determination is also performed at the time of an upload request, and attention processing is performed as necessary.

The process flow of the user terminal 5 and the blog server 1 when creating a blog will be described with reference to FIG.
A user who wants to create a blog article performs an operation of requesting a blog creation page from the blog server 1 on the user terminal 5. As a result, in step S10, the blog creation page is requested from the user terminal 5 to the blog server 1.
In response to this request, the blog server 1 transmits the blog creation page to the user terminal 5 in step S20. As a result, the blog creation page is displayed on the user terminal 5 by the web browser function. The user uses the blog creation page to input text data as an article and specify image data.
The blog creation in step S11 generally indicates the processing of the user terminal 5 when the blog article is created and edited on the screen by the user operation on the blog creation page.

During the creation of this blog, for example, the user may perform copy and paste operations. For example, when the blog server 1 detects a paste operation to the blog article being created (S21), the blog server 1 regards this as a judgment opportunity regarding citation and performs the first citation appropriateness determination process in step S22.
The first quotation adequacy determination performs a process such as searching for a copy source in another web page or the like for the text data or the image data pasted by the paste operation.
This first quotation adequacy determination is executed, for example, every time a paste operation is detected.

After completing the blog article, the user uploads it. In response to this operation, the user terminal 5 requests the blog server 1 to upload a blog article in step S12.
At this time, the blog server 1 makes a second citation appropriateness determination as a step S23, and determines whether or not an appropriate citation is made under a predetermined condition. However, the determination need not be a strict determination, and may be a determination such as “there is a possibility of copyright infringement” or “it cannot be said that there is no possibility of copyright infringement”.

In step S24, the blog server 1 determines whether attention is required.
If there is no part that is estimated to be a citation, or if it is determined that the citation is properly performed, it is determined that the reminder is not necessary, and the blog server 1 proceeds from step S25 to S27 to accept the upload, The upload process (transmission) of the user terminal 5 is received, and the upload process of storing the blog article data in the blog DB 51 is performed.

  On the other hand, if the blog server 1 determines that the attention is required, the blog server 1 proceeds from step S25 to S26, and performs the attention processing. In this case, for example, the upload is not started, and control is performed so that the user terminal 5 displays a reminder message along with the blog creation page. On the user terminal 5 side, a caution display is performed in step S13.

FIG. 5 shows an example of a state in which the alert display is being performed.
For example, in the blog article 60 that the user has created and tried to upload, for example, the frame display 61 clearly indicates a portion determined to be inappropriate citation. Of course, in addition to the frame display 61, the quoted portion may be indicated by a highlight display, a specific color display, an enlarged display, or any other method.
Further, the message display 62 displays a necessary message. In this example, unauthorized reproduction is pointed out, and an example of a display recommending that the source of the source is specified is used.
Of course, various message contents are possible. For example, as the applicable law, advice such as deletion of text, reduction of the number of characters, clarification of a quoted portion, change of a mode (size, font, etc.) of characters and the like may be shown.

  When such a reminder display is performed, for example, the user terminal side may return to the blog creation process (S11) to accept the user's edit. The user may make necessary edits and request uploading again so that inappropriate citations are not pointed out.

The outline of the processing flow of the blog server 1 and the user terminal 5 has been described above, but a specific processing example of the blog server 1 for realizing such processing will be described.
FIG. 6 shows an example of processing executed by the blog server 1 by the functions shown in FIG. Shows.

When a request for a blog creation page is detected from the user terminal in step S100, the blog server 1 proceeds to step S101 and transmits the blog creation page to the requesting user terminal 5.
Then, in step S102, the blog server 1 initializes the variable M to M = 0. The variable M is a variable for managing the number of times the citation source is found in the created blog article.

While the blog article is created / edited by the user's operation on the user terminal 5, the blog server 1 continuously performs the monitoring process of steps S103, S104, and S105.
In step S103, the blog server 1 monitors whether or not the blog creation page has ended on the user terminal 5. For example, this is the case when the user has stopped creating the blog article and closed the web page.
When the end of the blog creation page is detected, the blog server 1 ends the processing of FIG. 6 from step S103.

In step S104, the blog server 1 monitors the upload request from the user terminal 5.
In step S105, the blog server 1 monitors that the paste process is performed in the user terminal 5. That is, it is detected that the text data or the image data is pasted by the copy & paste operation as the blog article being created.

  When a paste operation is detected at some point during the creation of a blog article, the blog server 1 advances the process from step S105 to S106, and makes a first quotation adequacy determination. FIG. 7 shows a processing example of the first quotation adequacy determination.

In step S201 of FIG. 7, the blog server 1 identifies the pasted part in the blog article.
In step S202, the blog server 1 determines whether or not this copy & paste operation is performed in the blog article (or in the blog). For example, the data of the pasted part is copied from another part in the blog article being created, or is copied from another article of the blog (the blog currently being created). Check if there is. In such a case, the copy source is considered to be a sentence created by the user himself, so the paste operation this time may be a simple movement of a sentence, transcription of a self-sentence, or an operation for improving input efficiency. is there. Further, in this case, it is considered that the user's own text copy / paste operation does not cause the problem of copyright infringement. Therefore, it is not determined that there is a possibility of inappropriate citation, and the first citation suitability determination of FIG. 7 is finished from step S202.

If it is not the copy and paste from the blog or the article, the blog server 1 branches the process in step S203 depending on whether the pasted data is text data or image data.
If the data is text data, the blog server 1 proceeds to step S204, and acquires the text data for which the quotation adequacy is determined as the data for searching the copy source.
Then, in step S206, the blog server 1 compares the number of characters of the text data with a predetermined threshold thTN. If the number of characters is greater than or equal to the threshold thTN, the process proceeds to step S207, and if less than the threshold thTN, the process of FIG. 7 ends.
This is to exclude a case where the number of characters is small, which is unlikely to be quoted, and the threshold thTN is set to, for example, “10”. That is, if the number of pasted characters is less than 10 characters, it is regarded as not a citation and the first citation appropriateness determination is not performed. Of course, the threshold for this determination is not limited to 10 characters.

  If the pasted is image data, the blog server 1 proceeds from step S203 to step S205, and acquires the image data of the quotation adequacy determination as the data for searching the copy source. Then, the process proceeds to step S207.

In step S207, the blog server 1 acquires browsing history data from the user terminal 5.
For example, the browsing history of the web page managed by the browser is transmitted from the user terminal 5 and is acquired.
In step S208, the blog server 1 selects a survey target page from the web pages indicated by the browsing history.
All the web pages indicated by the acquired browsing history may be the survey targets.
Further, for example, by using the information of the browsing date and time indicated by the browsing history information, the web page browsed by the user within a predetermined time from the present may be the survey target.
Further, since the blog server 1 knows the date and time when the blog creation page is transmitted, the web page browsed after the date and time, that is, the web page browsed while creating the blog article may be selected as the survey target.

In step S209, the blog server 1 sets the variable N = 1 and the variable Nmax = the number of web pages to be surveyed. The variable N is a variable for distinguishing the web page selected as the survey target in step S208. The selected web pages are the first to the (Nmax) th web pages.
Then, in step S210, the blog server 1 investigates the Nth web page. This process is shown in FIG.

In step S220 of FIG. 8, the blog server 1 first branches the process depending on whether the data to be investigated (pasted data) is text data or image data.
In the case of text data, the blog server 1 accesses the Nth web page and acquires the page data in step S221.
In step S222, the blog server 1 confirms whether or not text data exists on the web page. If the text data does not exist, the web page cannot be the copy source, and thus the inspection of the Nth (eg, first) web page ends.
In this case, the blog server 1 proceeds to step S211 of FIG. 7, and if the variable N ≧ Nmax is not satisfied, that is, if the survey of all selected web pages has not been completed, the variable N is incremented in step S212 and the step is performed. Return to S210. Then, the process of FIG. 8 is performed for the Nth web page, that is, the next web page.

When it is determined in step S222 that the text data exists in the web page under investigation, the blog server 1 searches for the copy source text in the web page in step S223. That is, it is checked whether or not the same text data as the pasted text data exists in the web page.
If not, the process of FIG. 8 for the Nth web page is ended from step S224.

If the same text data as the pasted text data is found in the web page, the blog server 1 proceeds from step S224 to step S225, and determines whether it is a citation or a reprint.
It can be considered that a proper citation needs to be a part of the text or the like of the source (copy source). On the contrary, the whole or most part of the text data of the source is copied and pasted as a whole, which is not a citation but is considered to be a reprint, and in some cases, it may be reprinted without permission.
Therefore, in step S225, it is determined whether the text data portion related to the copy & paste operation is an amount that cannot be said to be a part of the text data in the copy source web page, and it is determined whether the text data is quoted or reprinted. To do.

Subsequently, the blog server 1 increments the variable M in step S226. Then, in step S227, information regarding the "Mth quoted portion" is generated for the paste portion where the copy source is found this time.
Specifically, the copy flag F (M) 1 is turned on. "(M)" indicates that the flag corresponds to the M-th quoted portion found in the blog article being created, and the current value of the variable M is inserted.
The fact that the copy flag F (M) 1 = 1 means that another website has been found as the copy source of the text data currently under investigation, and the blog server 1 uses the copy flag F (M) 1. (M) 1 is stored in association with the data of the paste portion.
The blog server 1 also sets a citation / reproduction flag F (M) it. For example, F (M) it = 0 is determined when it is determined to be "quotation" in step S225, and F (M) it = 1 is determined when it is determined to be "reprint", and the data is stored in association with the data of the paste portion.

In step S228, the blog server 1 acquires the source information about the Mth quoted portion (pasted portion) found this time. For example, the information on the URL of the Nth web page, the website name, the web page manager, etc. currently being investigated is acquired.
The blog server 1 stores this source information together with the data of the paste location, the copy flag F (M) 1 and the quotation / reprint flag F (M) it as the result of the first quotation adequacy determination. For example, it is stored in the RAM 103 or the storage unit 108 of FIG.

In step S229, the variable N is forcibly set to Nmax. This is because it is not necessary to investigate other web pages at the stage when the copy source is discovered, and thus the first quotation adequacy determination is ended.
That is, in this case, N ≧ Nmax in step S211 of FIG. 7, and the process of FIG. 7 is terminated.
For example, when five browsing histories are targeted for investigation from the browsing history information, five web pages are sequentially targeted for investigation by the processing of FIG. 8 until the copy source is found. Even if there is an unsearched web page, the first citation suitability determination will be completed. This prevents redundant investigation processing.

In this case, for example, the copy source may not be found in any of the five web pages. In that case, since the processes of steps S226, S227, and S228 are not performed, it is considered that the paste portion is not quoted.
For example, suppose that the user pastes the data created by himself / herself using another application software by copy and paste. In such a case, the paste part is not a quote and cannot be found from the web page in the browsing history. In such a case, the paste portion is not stored as the Mth quoted portion.
However, of course copy and paste from other people's text or images is not always from the web page. For example, an electronic book or other electronic content that is locally stored in the user terminal 5 can also be the copy source.
Therefore, the browsing history and the reproduction history including the local content may be acquired, and the copy source may be investigated for these.

If the paste portion is image data in the process of FIG. 8, the blog server 1 proceeds from step S220 to step S231 and accesses the Nth web page to acquire the page data.
In step S232, the blog server 1 confirms whether image data exists in the web page. If the image data does not exist, the web page cannot be the copy source, and the survey of the Nth web page is terminated.
When it is determined in step S232 that image data exists in the web page under investigation, the blog server 1 searches for the copy-source image data in the web page in step S233. That is, it is checked whether or not the same image data as the pasted image data exists in the web page.
If not, the process of FIG. 8 for the Nth web page is ended from step S234.

When the same image data as the pasted image data is found in the web page, the blog server 1 performs steps S234 to S226, S227, S228, and S229 in the same manner as the above text data. . In this case, the image data, the copy flag F (M) 1, the citation / reproduction flag F (M) it, and the source information are stored as the data of the Mth paste location as the result of the first citation suitability determination.
In the case of image data, the entire image is usually copied and pasted, so the citation / reproduction flag F (M) it can be considered to indicate "reproduction" in consideration of each image. .

When the copy source is found from the surveyed web pages and the processing of FIG. 8 is finished, or when the copy source is not found even after the survey of all the surveyed web pages is completed, In step S211 of FIG. 7, N = Nmax, and the first citation suitability determination of FIG. 7 ends.
In the first quotation propriety determination of step S106 of FIG. 6, the processing is performed as shown in FIGS. 7 and 8 above, and when the copy source of the pasted data is found, the information is the Mth quotation point. Will be managed as.
It is naturally assumed that the paste detection in step S105 is performed a plurality of times, but only when the probability of citation is high, the data of the Mth quoted portion is generated for the data of the paste portion.
Since the variable M is set to M = 0 in step S102 and then incremented in step S226 in FIG. 8 in which the copy source is detected, a number of copy and paste operations are performed until the blog article is completed. Is performed, the first quotation propriety determination is performed each time, and each time the copy source is found, the first quotation portion, the second quotation portion, ... Information of the determined result will be saved. That is, M paste locations are detected as quoted locations (including reprints). For example, if the copy source is never found by the time the blog article is completed, it means that the variable M = 0 remains and there is no quoted part.

When the user completes the blog article, he will perform the upload operation. The user terminal 5 sends an upload request to the blog server 1. In this case, the process of the blog server 1 in FIG. 6 proceeds from step S104 to S110, and the second quotation adequacy determination is performed.
FIG. 9 shows a specific example of the second quotation adequacy determination.

  In step S300 of FIG. 9, the blog server 1 confirms whether or not the variable M = 0. If the variable M = 0 as described above, it means that there is no paste portion determined to be a quoted portion. In that case, the second quotation adequacy determination is ended, and the process proceeds to step S111 in FIG.

On the other hand, if the variable M is not 0, it means that there is at least one paste portion determined to be a quoted portion in the first citation appropriateness determination in the blog article.
In this case, the blog server 1 substitutes the value of the variable M for the variable Mmax in step S302. The variable Mmax is the number of paste parts determined to be a quoted portion in the first quotation propriety determination.
Then, in step S303, the variable M = 1 is set. This is because the second quotation adequacy determination is performed in order from the first paste location determined to be the quotation location.

However, the paste portion determined to be the quoted portion in the first quotation adequacy determination may have been deleted at the time of this upload. This is because the first quotation adequacy determination is performed each time the paste processing is performed, and it is usually conceivable that the user deletes the paste portion in the process of creating the blog article after the paste processing. Therefore, at the time of an upload request, not all M paste locations remain.
Therefore, in step S303, the blog server 1 confirms whether or not the M-th quoted portion exists in the blog article to be uploaded. That is, the information on the M-th quoted portion stored in the first quotation propriety judgment is collated with the blog article at the time of the upload request, and it is confirmed whether or not the relevant portion is left.
If it is not left, it is not necessary to determine whether or not the portion is appropriate for citation. Therefore, in step S329, the blog server 1 sets a flag (copy flag F (M) 1, citation / reprint flag) for the M-th citation portion. F (M) it and all flags F (M) 2, F (M) 3, and F (M) 4, which will be described later, are reset (= 0), and the process proceeds to step S330. Then, in step S330, it is confirmed whether or not M ≧ Mmax (whether or not the second quotation adequacy determination has been completed for all quotation points), and if M ≧ Mmax, the variable M is incremented in step S331 and step S303. Return to. That is, the presence determination is performed for the next quoted portion.

When it is determined that the Mth quoted portion is present in the blog article, the blog server 1 branches the process in step S304 depending on whether the target data of the Mth quoted portion is text data or image data. .
If the data is text data, the blog server 1 proceeds to step S310 and calculates the ratio of the text amount of the quoted portion to the total text amount of the generated blog article.
Then, in step S311, it is determined whether the obtained ratio is equal to or more than the threshold value thT. For proper citation, it is considered desirable that the text (other than citation) is dominant in the content, and that the relationship between the text and the quote is master-slave. The threshold thT is a threshold for determining whether or not such a relationship is satisfied, and an appropriate ratio is set.

If the calculated ratio is greater than or equal to the threshold value thT, the blog server 1 proceeds to step S312 to turn on the flag F (M) 2, and if the calculated ratio is not greater than or equal to the threshold value thT, proceeds to step S313 and proceeds to flag F ( M) Turn 2 off.
The flag F (M) 2 is turned on when the quoted portion of the Mth quoted portion is not a subordinate description in the text. In other words, it is a flag indicating that there is a possibility that the citation is inappropriate due to the quantitative relationship between the text and the quoted portion.

Next, in step S314, the blog server 1 confirms the description of the source information for the Mth quoted portion.
If the blog article to be uploaded does not include the source information about the M-th quoted portion, the blog server 1 proceeds from step S315 to S316, turns on the flag F (M) 3, and the source information is described. If so, the process proceeds from step S315 to S317, and the flag F (M) 3 is turned off.
That is, the flag F (M) 3 is a flag indicating that the citation information for the Mth quoted portion is not described and there is a possibility that the quoted portion is inappropriate.
Since the blog server 1 stores the source information about the M-th quoted portion, when the source information is described in the blog article, it can be determined whether or not the source information is correct. Therefore, even if the source information is described, it is possible to judge whether it is correct or not, and if it is incorrect, turn on the flag F (M) 3.

Next, in step S318, the blog server 1 determines the character attribute of the Mth quoted portion. This is a judgment as to whether or not the citation is clearly distinguished from the text. For example, it is confirmed whether or not the character attributes such as character size, font, and color are clearly distinguished between the quoted part and the text.
If the distinction is not recognized, the blog server 1 proceeds from step S319 to S320 to turn on the flag F (M) 4, and if the distinction is recognized, proceeds from step S319 to S321 and flags F (M) 4. To turn off.
That is, the flag F (M) 4 is a flag that indicates that the M-th quoted portion may be inappropriately quoted in terms of clarity of the quoted portion.

  It should be noted that the clear distinction between the text and the quoted part does not need to be made in any of the character size, font, and color. For example, it is possible to make a clear distinction by enclosing the quoted portion in a frame, different arrangement of characters by indentation, and layout. Therefore, not only the character attribute but also other display modes may be considered for the determination.

  If the Mth quoted portion is text data, after performing the above processing, it is determined in step S330 whether or not the processing has been completed up to the last quoted portion. 2 In order to determine whether or not the quotation is appropriate, the variable M is incremented in step S331, and the process returns to step S303.

When the M-th quoted portion is image data and the process proceeds to step S320, the blog server 1 calculates the ratio of the image data of the quoted portion to the total display surface of the generated blog article.
Then, in step S321, it is determined whether the obtained ratio is equal to or more than the threshold value thP. For proper citation, it is considered desirable that the main body part of the content is dominant and the cited image data is in a subordinate position. The threshold value thP is a threshold value for determining whether or not such a relationship is satisfied, and an appropriate ratio is set.

  If the calculated ratio is greater than or equal to the threshold value thP, the blog server 1 proceeds to step S322 to turn on the flag F (M) 2. If the calculated ratio is not greater than or equal to the threshold value thP, proceeds to step S323 and proceeds to flag F ( M) Turn 2 off. That is, as in the case of text, a flag indicating that the text may be inappropriately quoted due to the quantitative relationship between the text and the quoted portion is controlled.

Next, in step S324, the blog server 1 confirms the description of the source information for the Mth quoted portion.
If the blog article to be uploaded does not include the source information about the Mth quoted portion, the blog server 1 proceeds from step S325 to step S326, turns on the flag F (M) 3, and the source information is described. If so, the process proceeds from step S325 to S327, and the flag F (M) 3 is turned off.
That is, as in the case of the text, the flag indicating that the citation may be inappropriate in terms of the description of the source information is controlled.
Also in this case, the blog server 1 determines whether the citation information about the Mth quoted portion is correct or not, and if it is incorrect, the flag F (M) 3. It is possible to turn on.

  If the M-th quoted portion is image data, after performing the above processing, it is determined in step S330 whether or not the processing has been completed up to the last quoted portion. 2 In order to determine whether or not the quotation is appropriate, the variable M is incremented in step S331, and the process returns to step S303.

  The blog server 1 finishes the processing of FIG. 9, that is, the second quotation adequacy determination in step S110 of FIG.

In step S111 of FIG. 6, the blog server 1 determines whether or not attention is required by using the results of the first and second citation appropriateness determinations.
For example, according to the first and second citation suitability determinations described above, the copy flag F (M) 1, the citation / reproduction flag F (M) it, the flag F (M) 2, the flag F (M) 3, the flag F ( M) 4 is set.
In particular, at the time of uploading, the flag F (M) 2, the flag F (M) 3, and the flag F (M) 4 are set in the second quotation adequacy determination for the quotation portion for which the copy flag F (M) 1 is turned on. Therefore, at the time of step S111, it is possible to confirm the citation / reprint flag F (M) it, the flag F (M) 2, the flag F (M) 3, and the flag F (M) 4.

For example, if even one of the citation / reproduction flag F (M) it, flag F (M) 2, flag F (M) 3, and flag F (M) 4 is "1", it is determined that attention is required. To do.
If the quotation / reproduction flag F (M) it, the flag F (M) 2, the flag F (M) 3, and the flag F (M) 4 are all "0", it is determined that no attention is required.

When it is determined that attention is not required, the blog server 1 proceeds from step S112 to S113 and shifts to upload processing. That is, the upload of the blog article is normally completed in response to the upload request.
On the other hand, if it is determined that the reminder is required, the blog server 1 proceeds from step S112 to step S120 and performs the reminder process. For example, the user terminal 5 is controlled to execute the alerting display as shown in FIG.

FIG. 10 shows a specific example of the alerting process.
The blog server 1 sets the variable M = 1 in step S401.
In step S402, the blog server 1 confirms the flag of the Mth quoted portion. For example, the citation / reproduction flag F (M) it, the flag F (M) 2, the flag F (M) 3, and the flag F (M) 4 are confirmed.

In step S403, it is confirmed from the above flag determination whether or not attention is required for the M-th quoted portion.
If all of the citation / reproduction flag F (M) it, flag F (M) 2, flag F (M) 3, and flag F (M) 4 are "0", a warning about the Mth quoted part is issued. Is unnecessary.
It should be noted that, for the citation portion that was determined to be the citation portion in the first citation appropriateness determination, but is not present in the second citation appropriateness determination, the flag is cleared in step S329 of FIG. Does not mean

On the other hand, if the warning is not required for the M-th quoted portion, the blog server 1 sets the warning content in step S404. This may be set according to the flag set to "1".
When the quotation / reprint flag F (M) it = 1, the attention including the content indicating the possibility of reprint is issued. You may make it include the message which recommends deletion of the said part.
When the flag F (M) 2 = 1, the attention is included including the content notifying that the quoted portion is not subordinate in the content. A message recommending deletion of quoted parts or reduction of the number of characters, or a message recommending increasing the text may be included.
When the flag F (M) 3 = 1, the attention including the content notifying that the citation portion is not clearly stated (or the description may be incorrect) is issued.
Source information may be presented.
When the flag F (M) 4 = 1, the attention including the content notifying that the quoted portion is not clearly distinguished from the text is issued. A notification for teaching a method for distinction, for example, a change of character attribute may be included.

  In this way, the attention content is set according to the flag. For example, message contents are set. Of course, a composite message may be generated by using a plurality of flags.

In step S405, the blog server 1 confirms whether or not M ≧ Mmax. If M ≧ Mmax, the variable M is incremented in step S406 and the process returns to step S402. That is, the process moves to the setting process for calling attention to the next quoted part.
The blog server 1 moves from step S405 to step S407 at the time when the process has been completed up to the last quoted portion, and performs attention control. That is, the user terminal 5 is controlled so that the content set in step S404 is alerted.

With such a reminder, the user can recognize the place where there is a possibility of copyright infringement, make the necessary corrections, and issue the upload request again.
For the user, carelessness or lack of knowledge about quoting prevents the possibility of copyright infringement without knowing it.

In the first embodiment described above, if the copy source cannot be found, it is determined that it is not a quotation. However , regarding the pasted part, a caution such as "please enter the source if it is a quotation" It is also possible to do.

In addition, when the upload request is made, the second quotation adequacy determination is performed, but this is a flag setting process for the already-quoted citation portion, and is not a process that takes much time. The first citation suitability determination, which takes a relatively long time, is performed during the creation of the blog. Therefore, it does not cause a long waiting time after the user makes an upload request. Therefore, it is possible to appropriately call the attention without deteriorating the usability of the user.
Further, the second quotation adequacy determination may be made only for the quotation part left in the blog article at the time of the final upload, and unnecessary determination is unnecessary. This point is also suitable for requesting prompt processing at the time of upload request.
Further, the first quotation adequacy determination is performed while the blog article is being created, so that it is not required to be so prompt. This is advantageous in that the copy source can be found and the processing load on the blog server 1 is not tightened.

<4. Second Embodiment>
The processing of the blog server 1 according to the second embodiment will be described with reference to FIG. In FIG. 11, the same processes as those in FIG. 6 are designated by the same reference numerals to avoid redundant description.
11 is different from the process of FIG. 6 in that steps S105 and S130 to S134 are performed as the process of the blog server 1 (determination opportunity detection unit 12).

If more paste operations are detected, the process of the blog server 1 proceeds from step S130 to step S134, and it is determined whether the pasted part is text data and is less than the predetermined number of characters. The predetermined number of characters is set to a small number of characters such as 10 characters. This is usually set to be used for determining the number of characters when it is unlikely to be quoted.
When the number of characters is equal to or more than the predetermined number, the process proceeds to step S106.
In other words, if the pasted part is text data having less than the predetermined number of characters, it is determined that it is not a citation (the possibility of citation is very small), and the process of the first citation appropriateness determination in step S106 is not proceeded. .

By doing so, it is possible to prevent the first citation appropriateness determination from being executed in response to all the copy and paste operations that are considered to be frequently performed. That is, when the possibility of citation is extremely low, the processing load of the blog server 1 is prevented from becoming excessive by proceeding to the first citation appropriateness determination.
Note that the above processing is the same as that of step S206 in FIG. 7, and the difference is whether or not to determine the number of pasted characters as a condition for entering the first quotation adequacy determination. When the process of step S134 is adopted, step S206 of FIG. 7 is unnecessary.

Further, in FIG. 11, the first quotation adequacy determination may be performed in some cases other than the detection of the paste operation.
In step S130, the blog server 1 determines whether the text data input by the user for creating the blog has progressed by a predetermined amount. For example, it is determined whether or not the undetermined amount of text has been input by a predetermined amount or more after the determination of the previous step S132.
The predetermined amount is not strictly determined only by the number of characters, but it is determined whether or not the number of characters is equal to or more than a predetermined amount, and there is an input in a range delimited by one or more paragraphs, line breaks, line breaks, etc. as a sentence. Good to do.

When such a condition is satisfied, the blog server 1 proceeds to step S131, acquires the text data of the newly input portion for determination, and performs self-sentence determination in step S132.
This is to determine whether or not the input text data can be estimated as the user's own text.
For example, stylistic analysis is performed on another blog article of the user or the text of another portion being created, and the habit / propensity of the text of the user is grasped. This may be done in advance for each blogger. Then, in step S132, similar analysis is performed on the newly input portion to determine the habit / propensity of the sentence. Then, by comparing them, it is estimated whether or not the part input this time is a sentence that the blogger has uttered himself.

  As elements for determining a habit or tendency of a sentence, for example, frequently used words, punctuation habits (insertion frequency), tendency of using pictograms (frequency of use), specific symbols (“?” “!”, Etc.) Frequency of use, length of one sentence, frequency of use of specific styles such as stylization, frequency of line breaks, tendency to use "do-masu" and "is" key, frequency of mixing foreign languages and characters, etc. Can be considered. These points are digitized and compared to determine the similarity. If the similarity can be confirmed, it is estimated that the sentence is created by the user himself.

When the blog server 1 is estimated to be a sentence thought by the user who is creating the blog article, the blog server 1 determines that the sentence is a self-sentence in step S133, and returns to step S103. If it is not estimated that the sentence was thought by the user himself, the blog server 1 proceeds to step S106 to make a first citation suitability determination for the portion.
That is, in the text data in which the blog article is being created, when a portion having different style characteristics is detected, it is detected as a determination opportunity of the portion, and the first citation appropriateness determination is performed.

As described above, the second embodiment is different from the first embodiment in the method of detecting the determination opportunity for performing the processing of the first quotation adequacy determination.
As a result, it is possible to prevent the paste processing from excessively reacting.
Further, the quoting adequacy determination process can be applied to a case where a person's text is cited by means other than paste.

<5. Third Embodiment>
The processing of the third embodiment will be described with reference to FIG. This is an example of processing in which the function of the quotation notification unit 16 shown in FIG. 3 is added.
FIG. 12 shows the user terminal 5, the blog server 1, and the user terminal of the administrator of the web page that is the source of the quotation (“user terminal 5A” for distinction) as processing after the upload (S14, S27) of FIG. (Denoted as)) and communication.

After completing the upload process in step S27, the blog server 1 confirms in step S28 whether or not the blog article uploaded this time includes a quoted portion.
If the blog article does not have a quoted portion, the process proceeds to step S35, and the blog article is made public.

  If there is a quoted portion, the blog server 1 proceeds to step S29 to determine the notification condition. For example, from the results of the first and second citation appropriateness determination processing, it is determined whether or not the legality of the citation is high as a notification condition, and if it does not correspond to the high legality, the citation source is notified. To do.

  For example, if the legality of the citation is high, the notification is unnecessary, and the blog server 1 proceeds from step S30 to S35. If not, the procedure proceeds to step S31 to notify the administrator of the web page of the citation source. I do. For example, the fact that the quotation is specified on the user terminal 5A is presented to the user who is the source of the quotation. Also, ask for a response of permission / non-permission. On the user terminal 5A, these contents are displayed in step S51.

When the quoting source user makes an answer (S52), the blog server 1 confirms the answer in step S32, and determines whether or not the disclosure permission is obtained.
In some cases, the reply from the quoting user may not be obtained. If the blog server 1 does not receive an answer after a certain period of time, it may be considered that the disclosure is not prohibited. This is because the blog article that was originally uploaded has undergone the first and second citation appropriateness determinations, and in some cases, has undergone a warning process, and it can be said that the legality to some extent has been secured by clearing these. is there.
It should be noted that, of course, the operation may not be made public unless an answer is obtained from the quoting user.

When the publication is permitted, the blog server 1 proceeds from step S33 to S35. On the other hand, when the publication is not permitted, the blog server 1 proceeds to step S34, and sends a correction notice to the user terminal 5 of the user who created the blog article. At this time, it is possible to urge the deletion of quoted parts and the appropriate display of credits.
A correction notice is displayed on the user terminal 5 (S15). After that, the user may make corrections such as deletion of quoted portions accordingly (S16) and upload again.

In this way, when the source of the quoted portion is a web page such as another blog article, by notifying the quoting user that the citation has been made, the quoting source user can confirm the citation status. .
Further, by asking the quoting source user whether or not the quoted portion can be used, and if the quoting portion is not permitted, the user who created the blog article is notified and correction is requested, whereby troubles between users can be prevented.

<7. Summary and Modifications>
In the above embodiment, the following effects can be obtained.
The blog server 1 responds to the determination opportunity detection unit 12 that detects that a determination opportunity regarding citation has occurred during the creation of a blog article (content) in the user terminal 5, and that the determination opportunity detection unit 12 detects the determination opportunity. While the blog article is being created, the first citation appropriateness determination unit 13 that determines whether or not the citation is appropriate using the browsing history information in the user terminal 5, and the determination set at the timing of the blog article upload request from the user terminal 5. A second citation appropriateness determination unit 14 that makes a citation appropriateness determination using a criterion, and an alert that performs a process of executing an alert display in the user terminal 5 according to the results of the first citation appropriateness determination and the second citation appropriateness determination The unit 15 is provided.
For example, when text data or image data of other content is pasted into the blog article being created, the user may believe it as a proper citation, or may be indifferent to copyright etc. It may be done without doing it. Moreover, it is often difficult or impossible to judge whether or not the quote is actually legal. In such cases, the uploaded and published blog posts carry the risk of copyright infringement.
According to the processing of the present embodiment, when such a risk occurs, it is possible to warn the user (blogger) at the stage of uploading and warn the user, and it is possible to prevent the publication of a risky blog article.
In addition, such an alert can provide an environment in which a well-meaning user can create a blog with some freedom and peace of mind.
Then, in particular, the first quotation propriety determination is performed while the user's blog is being created. In the first citation suitability determination, a process of checking whether or not text data or image data having the same content exists in the web page browsed by the user by using the browsing history, and searches for the copy source (source). To do. This search may take a certain amount of processing time, but by performing it while the blog is being created, it is possible to prevent the user from feeling the time. In other words, if such a process is performed at the time of uploading, the uploading time including the determination becomes long and inconvenient for the user, but such a situation will not occur.
Further, in the first quotation propriety judgment, rather than crawling a huge website, by targeting a specific website by using the operation history / history information of the user, the processing load is significantly reduced, and the quotation is performed. The chance of discovering the origin is high.
The second quotation propriety determination is performed at the time of the upload operation (at the time when the user recognizes that the blog is completed), and is one of the requirements for legal quotation. Can correctly judge the relationship. In other words, since the user does not need to repeatedly judge the quantitative relationship in response to the text being written, the wasteful processing will not occur.
Also, the alert is issued at the time of the upload operation (when the user recognizes that the blog is completed), so that no unnecessary instruction is given during the creation. For example, even if the user once pastes it, he or she does not use it as it is, but deletes it or edits it into a completely different sentence, so that it is often unrelated to the citation. Therefore, if the user is alerted each time, the situation may cause the user to feel "I thought I should fix it ...", but the blog creation environment may not be comfortable. It is possible to provide the user with a blog creation environment with good usability by avoiding such excessive or unnecessary alerting.
As described above, in the embodiment, it is possible to provide a comfortable blog creation environment to the user and assist the blog with inappropriate quoting from being published.

In the first embodiment, the example has been described in which the user terminal 5 executes the alert display including the guide information for making a proper quotation. For example, information for assisting in writing the source, a message recommending deletion of a part of the paste portion, addition of the blog text, etc., and presentation of a model such as the source writing or the writing mode.
For example, even if the user intends to properly quote, it is often difficult to know how to actually describe the quoted part. Therefore, the user can easily make necessary corrections by guiding what to do when calling attention. This makes it possible to accept uploads by modifying the quotation mode without wasting the blog articles created by the user.
It should be noted that even if the user does not revise, it is possible to automatically correct the description mode of the quoted portion after requesting the user's consent. For example, the font size and font are changed, and store opening information is added. This can save the user the trouble of correction.

In the first and second embodiments, an example has been described in which the paste operation is detected in the blog article being created, so that the paste operation is detected as a determination opportunity.
The quoted portion is usually inserted into the content being created by a copy and paste operation of text data or image data. Therefore, if there is a paste operation, it is determined that the quotation has been performed and the first quotation adequacy determination is performed.
By detecting the paste operation, the citation determination process can be executed for a portion that may be cited, and omission of the determination can be reduced. In addition, the possibility of citation can be estimated by the simple process of detecting the paste operation, and the determination opportunity can be easily detected.
As a general operation, the pasted sentence may be edited immediately after the copy and paste. For example, you may want to copy a reference text and edit it to describe your desired text. In such a case, the first quotation adequacy determination may be a useless process. Therefore, after the paste operation is detected, if the paste portion is not edited and a predetermined time elapses or input of another sentence is made, even if it is determined that the paste is detected in step S105 of FIG. 6, for example. Good. As a result, it is possible to prevent unnecessary processing from occurring.

In the second embodiment, an example has been described in which the paste operation of a predetermined number of characters or more is detected in the blog article being created, and the paste operation is detected as the determination opportunity.
The copy and paste operation is an operation that is frequently performed by a user during document creation, and a paste operation of a small number of characters is often performed. Then, the first quotation adequacy determination is made in accordance with the paste operation, which unnecessarily increases the processing load. Therefore, in the case of a paste operation of a small number of characters, which is normally difficult to think of as a citation, it is not estimated as a citation and the useless first citation appropriateness determination is not performed (see S134 in FIG. 11). This can reduce the processing load on the blog server 1.

In the second embodiment, an example has been described in which, in the text data of the blog article that is being created, when a portion having different style characteristics is detected, the portion is detected as a determination opportunity.
In other words, the quoted part is estimated from the difference in wording. For example, referring to the user's past post, the characteristics of the user writing style are specified by morphological analysis, and the portion other than the user writing style in the article is set as the quoted portion.
The style of users who create blog articles is unified to some extent within the blog. If there is a part of the writing style that is different from the usual style in the sentence, it can be inferred that the part may be another person's writing. Therefore, by using such a case as a judgment opportunity regarding citation, it is possible to make a citation appropriateness judgment target even for a citation portion that is not operated by copy and paste (see S131 to S133 in FIG. 11).
In particular, by using together with the estimation based on the operation detection of copy and paste as in the processing of FIG. 11, it is possible to determine a portion having a possibility of being quoted with high probability.

In the first embodiment, an example of performing a process of searching the web page data indicated by the browsing history information in the first citation suitability determination and confirming whether or not the same data as the portion estimated as the citation exists Said.
It is considered that a user who writes a blog article may quote from a web page that was being viewed or was being viewed before creation. Therefore, the range of crawling for searching the citation source is narrowed down based on the browsing history (see S207 to S210 in FIG. 7). As a result, the processing load for searching the copy source is reduced.

In the first embodiment, the first citation suitability determination is the same as the location estimated to be a citation by searching the web page data extracted by the browsing time condition in the web page data indicated by the browsing history information. The example of performing the process to confirm whether or not the data exists has been described.
That is, not all of the browsing history information, but the copy source of the text data or the image data is searched for from the web page data corresponding to the browsing time condition such as within the latest predetermined time or after the start of blog creation.
A user who performs a copy & paste operation on a blog article usually copies text data or image data from another web page viewed in a short time.
In particular, when a quoted portion is pasted by a copy and paste operation, it is assumed that the copy operation is often performed during the creation of a blog article.
Therefore, the web page to be searched is selected according to the condition of the browsing time (see S208 in FIG. 7). As a result, it is possible to prevent the accuracy of the search range from lowering while further reducing the load of the search processing of the copy source.

In the first embodiment, an example of determining the presence or absence of the information indicating the source of the quoted portion is given as one of the determination criteria in the second quotation adequacy determination.
That is, it is confirmed whether or not the source (citation source) is described for the portion estimated to be cited.
Since it is considered that the citation of the source is one element of proper citation, it is possible to guarantee one of the requirements for appropriateness by determining the presence or absence of it. As a result, it is possible to properly guide the user (see S314 and S324 in FIG. 9).
Specifically, for example, it is determined whether or not there is a URL of another web page, a title, or the like.
In addition, when the URL or the like is described for the quoted portion at the stage of the original creation by the user, it can be determined whether or not the citation is valid. For example, if a quoted part and a URL are arranged in combination in an article, but the quoted part is not found in the web page referenced from the URL, it is possible to determine that the source is not valid. In that case It is also possible to display a message such as "The written source may be incorrect" together with the warning.

In the first embodiment, an example in which the ratio of the amount of the quoted portion and the content body is determined as one of the determination criteria in the second quotation propriety determination has been described.
That is, the amount of the quoted part and the amount of the text are compared.
It is considered that the ratio (the master-slave relationship in the content) of the amount of the quoted part and the text (the part excluding the quoted part) is one of the appropriate judgment criteria for the quote, and therefore this is judged (S310 and S320 in FIG. 9). reference). Thus, by confirming one element of whether the citation is appropriate and notifying the user, it is possible to provide the user with an appropriate guide.

In the first embodiment, an example of determining the difference between the character aspect of the quoted portion and the character aspect of the content body as one of the determination criteria in the second quotation propriety determination has been described.
That is, it is determined whether or not the portion estimated to be cited is described in a manner that is clearly different from the text.
It is considered that one of the appropriate citation determination criteria is that the quoted portion is clear in the text (excluding the quoted portion), so this is determined (see S318 in FIG. 9). Thus, by confirming one element of whether the citation is appropriate and notifying the user, it is possible to provide the user with an appropriate guide.

In the third embodiment, the case has been described in which the citation notifying unit 16 that performs processing for notifying the source that the citation is performed is provided.
This allows the source user to confirm the citation status. In addition, the idea of the source user can be fed back to the blog creator. For example, bloggers can publish their blog posts with peace of mind if they get permission from the source. Also, if there is a disapproval response from the quoting source, the blogger can take appropriate measures (such as correction of blog article contents).
If the source user refuses to use the quoted portion, it is possible to notify the quoting user of the fact and to prompt the user to delete the quoted portion or display an appropriate credit. By these measures, the function of preventing troubles between users can be fulfilled.

The processing example of the embodiment is an example, and various other modified examples are possible.
There are other possible detection items such as the detection of the determination opportunity for the first citation appropriateness determination and the determination items for the second citation appropriateness determination.
Further, the technology of the embodiment is applicable not only to blogs but also to various contents such as texts and images (still images / moving images).

<8. Program and storage medium>
The program of the embodiment executes at least the processing of the determination opportunity detection unit 12, the first citation appropriateness determination unit 13, the second citation appropriateness determination unit 14, and the alerting unit 15 in the blog server 1 to the information processing device (CPU or the like). It is a program to let.

  The program according to the embodiment includes a determination opportunity detection function (S105, S130 to S134) for detecting that a determination opportunity for citation has occurred during content creation in the terminal device, and a determination opportunity detected by the determination opportunity detection function. According to the first quotation propriety determination function (S106 and FIG. 7, FIG. 8) that determines the quotation propriety using the browsing history information in the terminal device during content creation, and the timing of the content upload request from the terminal device. According to the second quotation propriety determination function (S110 and FIG. 9) for performing the quotation propriety determination using the criterion set in step 1, and the determination result by the first quotation propriety determination function and the second quotation propriety determination function. And a warning function (S120 and FIG. 10) for performing a process of displaying a warning display in the device. Is a program for row.

With such a program, one or more information processing devices as the blog server 1 described above can be realized.
Then, such a program can be stored in advance in a HDD as a storage medium built in a device such as a computer or a ROM in a microcomputer having a CPU. Alternatively, it can be stored (stored) temporarily or permanently in a removable storage medium such as a semiconductor memory, a memory card, an optical disk, a magneto-optical disk, or a magnetic disk. Further, such a removable storage medium can be provided as so-called package software.
Further, such a program can be installed from a removable storage medium to a personal computer or the like, or can be downloaded from a download site via a network such as a LAN or the Internet.

  Further, such a program may be installed in the user terminal 5 as an application program, and the above-described processing may be executed in the user terminal 5. That is, for example, the processing of the determination opportunity detection unit 12, the first citation appropriateness determination unit 13, the second citation appropriateness determination unit 14, and the alerting unit 15 by the blog server 1 of the embodiment is performed by an application program installed in the user terminal 5. Try to run. This makes it possible to provide a blog creation environment with good usability without intervening with the blog server 1 during blog creation, and to assist in preventing uploading of a blog that is inappropriately quoted. In that case, the user terminal 5 also corresponds to the information processing device in the claims.
