     TECHNICAL FIELD 
     The present invention relates to a news server for trackback between a news and a blog and a method for interconnecting thereof. 
     BACKGROUND ART 
     As the internet technology has developed, news service and blog service through the internet communications network are getting used much more. The internet news service of the related art simply provided an article to readers by means of internet. Recently, however, a user may leave a feedback on a certain article by means of a reply, comment or talkback function, which is then provided to other users of the news service in the form of a bulletin board or list. This kind of internet news service makes it possible for the service users to easily share their opinion about an article, grasp the direction of the public opinion about the subject of the article, and discuss with other users about the news. 
     The term ‘blog’ is the abbreviation of ‘weblog’ which is the compound word of ‘web’ and ‘log’. Blog service means a service providing a web page operated by an individual. Blog functions as a one person media operated by a user himself (or herself) thereby making the user not only an information consumer but also an information provider such that he (or she) might build a personalized media. For this reason, the number of blog users currently increases. According to the general way to operate the blog service of the related art, a blog operator posts a blog content and the other user reads the blog content and leaves a comment on it. 
     Meanwhile, as the blog service develops, a trackback function has been added to the service so as to provide a better way for the user to leave his or her opinion about the blog content. While the comment of the related art is left in the bulletin board of the corresponding blog, the trackback function enables the comment to be left not only in the corresponding blog but also in other blogs. When a user wants to leave a comment upon a content of “A” blog, for example, (s)he may input the comment not in “A” blog but in his(her) own “B” blog and set the “A” blog as a trackback destination such that a portion of the contents of the “B” blog be posted in the bulletin board of the “A” blog. That is, the trackback function makes two different blogs linked to each other, thereby inducing more interaction as to a certain subject and facilitating easier sharing for information and idea on the subject. 
     On the other hand, since a number of users make comments on a certain article in an internet news service, the number of letters of a comment is limited to a predetermined number to prevent a user from expressing his (her) opinion too much. 
     Thus, there are problems in the internet news service of the related art in that it is difficult for a user to express his or her in-depth opinion through a comment, it is difficult for a user to make consecutive discussion with other users about a subject when lots of users leave lots of comments causing a comment to be subordinate rapidly, and it is impossible for a user to manage his (her) own comment. 
     In case of a blog operator who wants to provide more information to other users of an internet news service when an article of the news service corresponds to the subject of his (her) blog, (s)he may simply leave the URL address of his (her) blog as a comment on the article, which is, however, a troublesome way to lead the users to his (her) blog since the users are required to copy the URL address and paste it to the web browser to access his (her) blog. 
     Finally, it is difficult to make a sound discussion in case of comments in news services since there is much likely to be irresponsible curse and swearword due to its one-time writing and anonymity.

     DETAILED DESCRIPTION 
     Reference will now be made in detail to an embodiment of the present invention, example of which is illustrated in the accompanying drawings. 
       FIG. 1  shows a suitable system for interconnecting a news and a blog through trackback according to an embodiment of the present invention. The trackback interconnecting system suitably comprises at least one user terminal  300  capable of intercommunicating through a communication network, at least one blog server  200 , and a news server  100 . 
     The user terminal  300  suitably may be a computer, a PDA, portable IT equipment or a mobile as far as it can access to the communication network such as internet. 
     The blog server  200  is similar with the blog server of the related art in that it provides the user terminal  300  with a service for making, managing and updating a personalized webpage. The blog server  200 , as shown in  FIG. 2 , comprises a blog service providing means  210  and a first trackback interconnecting means  230 . The blog service providing means  210  provides such a conventional service as receiving a blog content  500  from the user terminal  300  and posting it. The first trackback interconnecting means  230  suitably provides a trackback service for trackback with other blogs. The first trackback interconnecting means  230  may provides the trackback service for trackback with other blogs provided by the blog server  200  itself and with the blogs provided by other blog servers connected to the communication network as well. 
     The news server  100  suitably comprises a news article providing means  110 , a news comment providing means  120 , and a second trackback interconnecting means  130 . The news article providing means  110 , as in the conventional case, provides a news article (news_artc) to the user terminal  300 . The news article (news_artc), as shown in  FIG. 3 , may be provided in the form to be displayed on the screen of the user terminal  300  connected to the news server  300 . 
     The news comment providing means  120  suitably receives a news comment (news_cmt) on the news article (news_artc) from the user terminal  300  and provides the user terminal  300  with the news comment (news_cmt). The news comment providing means  120  suitably comprises a news comment inputting means  122 , a news comment database  124 , and a news comment outputting means  126 . 
     The news comment inputting means  122  suitably provides the user terminal  300  with a news comment input interface  420  through which the news comment (news_cmt) is received. The news comment (news_cmt) is classified according to the news article (news_artc) and saved in the news comment database  124 . The news comment outputting means  126  suitably provides a news comment output interface  430  for providing the user terminal  300  with at least one news comment (news_cmt) per a news article (news_artc). 
     The second trackback interconnecting means  130  suitably communicates with the first trackback interconnecting means  230  and provides a service for trackback between the blog content  510  and the news comment (news_cmt,  435 ). When trackback is requested, one of the first trackback interconnecting means  230  of the blog server  200  and the second trackback interconnecting means  130  of the news server  100  transmits a trackback ping to the other which replies to it so that they are interconnected with each other. 
     The trackback ping transmitted when track back is requested may be constructed as follows. 
     POST http://www.blog.naver.com/trackback/5 
     Content-Type: application/x-www-form-urlencoded; charset=utf-8 
     title=Foo+Bar&amp;url= 
     In this instance, the ‘title’ is the title of the blog content  510  or news comment (news_cmt) and the excerpt is the entire or a portion of the body of the blog content  510  or news comment (news_cmt). The ‘url’ indicates the URL address of the original text. In case of trackback of the news comment (news_cmt) made through the news server  100  to the blog server  200 , the URL address of the HTML page where the corresponding news comment (news_cmt) is posted is set as the ‘url’. On the other hand, in case of trackback of the blog content  510  made through the blog server  200  to the news server  100 , the URL address of the HTML page where the corresponding blog content  510  is posted is set as the ‘url’. 
     The news server  100  or blog server  200  which received trackback request through a trackback ping (trac_ping) verifies the validity of the trackback ping (track_ping). If it is valid, the trackback target is posted on the blog bulletin board or the news comment bulletin board, and then a message of successful trackback is transmitted to the server which requested the trackback. Otherwise, a message of failure of trackback is transmitted to the server which requested the trackback. 
     More various functions may be suitably embodied in the trackback service between a news and a blog if the trackback ping (trac_ping) further includes supplementary information. Hereinafter, referred to  FIG. 3  to  FIG. 6 , the each cases of the various functions will be made. 
       FIG. 3  shows a suitable scheme of trackback interconnection between a news and a blog according to an embodiment of the present invention. The news server  100  suitably provides the user terminal  300  with the picture on the left of  FIG. 3 . The news service picture suitably comprises a news article  410 , a news comment output interface  430 , and a news comment input interface  420 . As showin in  FIG. 3 , they may be suitably provided all together as elements of one picture while each of them, according to a user&#39;s option, may be displayed by means of pop-up or picture conversion. 
     The blog server  200  suitably provides the user terminal  300  with the picture on the right of  FIG. 3 . The blog service picture may suitably comprise a blog content  510  and a blog category  530  on one side of the picture. 
     When trackback is set between the news server  100  and the blog server  200 , a user may select one of the news server  100  or blog server  200 , make a comment though the selected one, and request a trackback of the comment to the other, such that each of the news comments  435  and blog content  510  of the same contents as shown in  FIG. 3  may be provided by the each corresponding servers  100 ,  200 . 
     First, explanation will be made on the embodiment where the user terminal  300  makes the news comment (news_cmt) using the news comments input interface  420  provided by the news server  100  and then requests a trackback to the blog server  200 . In this case, the news comments input interface  420  suitably may comprise a news comment input unit  421 ,  422  for receiving the input of the news comment (news_cmt) and a trackback selection unit  423  for requesting a trackback of the inputted news comment (news_cmt). 
     To set up a trackback with the blog server  200 , the news server  100  should be aware of the URL information of the blog to which a user wants a trackback.  FIG. 4  shows an embodiment where the trackback selection unit  423  further comprises a URL address input window for receiving the URL information of the blog from the user terminal  300 . 
     Optionally, as shown in  FIG. 5 , the news server  100  suitably may comprise a user information database to store designated blog information (blog_info) by users, the designated blog information including the URL information of a blog to which a user wants trackback. The second trackback interconnecting means  130  may trackback the news comment (news_cmt) inputted through the news comment input unit  421 ,  422  based on the designated blog information when a users requests a trackback through the trackback selection unit  423 . According to this embodiment, convenience of making a news comment improves since a user does not have to input the URL information of his (her) blog whenever (s)he makes a news comment. 
     In the case of a user who operates a plurality of blogs, for example, blog A and blog B, it is desirable that the user manages his (her) blogs more specially by setting up the blogs as trackback targets based on the subjects of news articles, for example, by setting up the blog A as a trackback target for a political news and setting up the blog B as a trackback target for a IT news. For this purpose, as shown in  FIG. 6 , a plurality of the designated blog information classified by users is suitably stored in the user information database  140 , at least one among the plurality of the designated blog information is selected  424  by the user terminal  300  through the trackback selection unit  423 , and the second trackback interconnecting means  130  suitably sends a trackback request for the news comment inputted through the news comment input unit  421 ,  422  according to the selected designated blog information (sel_blog_info). 
     In most blog services, as shown in  FIG. 3 , a user may set a blog category  530  so as to post a blog content based on its subject. It is preferred that, therefore, a user may trackback a news comment (news_cmt) to a blog according to the blog category  530  pre-registered through the blog server  200  by the user. For this purpose, as shown in  FIG. 7 , a blog category  530  corresponding to the designated blog information (blog_info) is suitably further selected by the user terminal  300  through the pull-down menu  425  of the trackback selection unit  423 , the second trackback interconnecting means  130  trackbacks the news comment (news_cmt) with the selected blog category information (blog_ctgr_info), and the blog service providing means  210  posts the news comment (news_cmt) on the selected category as a blog content  510 . In this case, the news server  100  receives in advance from the blog server  200  the category information of the blog corresponding to the designated blog information (blog_info) and transmits it to the user terminal  300  when a news comment is inputted. According to this embodiment, inconvenience is reduced in that a user does not have to re-categorize the news comment according to the created blog category. 
     Recently, a blog service creates a privilege to open for each of the blog contents so as to prevent the infringement of the individual privacy. It is preferable that a user creates a privilege to open when (s)he makes a news comment (news_cmt) in consideration of the characteristics of the blog service to which many and unspecified persons may access, so as to prevent the individual&#39;s thought or privacy from being revealed. For this purpose, as shown in  FIG. 8 , a privilege to open with respect to the blog corresponding to the designated blog information (blog_info) is further selected by the user terminal  300  through the trackback selection unit  423 , the second trackback interconnecting means  130  trackbacks the news comment (news_cmt) with the selected privilege to open information (blog_prv_info), and the blog service providing means  210  posts the news comment (news_cmt) according to the selected privilege to open. Consequently, inconvenience is reduced in that user does not have to access to his (her) blog again after making a news comment (news_cmt) to set up a privilege to open with respect to the trackbacked news comment. To further improve the users convenience, the news comment (news_cmt) is configured to be “open to public” as a default when the news comment (news_cmt) is made, and the news comment (news_cmt) may be changed to be “close to public” at the user&#39;s option through the news server  100  or blog server  200  when the new comment (news_cmt) is made or after the news comment is registered. 
     According to the related art, a reader of a news article who wants to request more detailed information about the news article or send a feedback on the news article such as objection, protest, and encouragement, needs to call the pressman of the news article or to send the corresponding contents to the pressman through e-mail by driving a separate e-mail application. However, since the method of the related art requires additional time and endeavor, only a few readers send the pressman their opinion on the news article as a feedback. According to the embodiment of the present invention shown in  FIG. 8 , however, the news article providing means  110  is configured to provide a pressman blog information  114  of the pressman in addition to the news article, the trackback selection unit  423  is configured to further receive the selection of whether to trackback the news comment (news_cmt) to the pressman s blog from the user terminal  300 , and if so, the second trackback interconnecting means  130  further trackbacks the news comment (news_cmt) inputted through the news comment input unit  420  to the pressman s blog according to the pressman blog information (prss_blog_info). Consequently, much more users or readers are likely to send their opinion on a news article to the corresponding pressman as a feedback conveniently. 
     Below is explained an embodiment of the present invention where a blog content  510  is made through a blog server  200  and is trackbacked to a news server  100  as a news comment (news_cmt). The trackback from the blog server  200  to the news server  100  is similar with the trackback of the related art between the blog servers  200 ,  250 . For the trackback to the news server  100 , the trackback information of a news article on which a news comment (news_cmt) would be made should be known. Thus, as shown in  FIG. 9 , it is desirable that the news article providing means  110  of the present invention further provides news article trackback information  411  in addition to the news article, the news article trackback information  411  comprising the URL information of the news article (news_artc). According to this embodiment, a user accesses to his (her) blog, makes a news comment on the news article in the form of a blog content  510 , and sets up trackback of the news comment to the corresponding news server  100  based on the news article trackback information  411  provided. The second trackback interconnecting means  130  of the news server  100  receives the trackback request from the first trackback interconnecting means  230  of the blog server  200  and, according to the trackback request, outputs the blog content transmitted from the blog server  200  through the news comment outputting means  126  of the corresponding news article. According to this embodiment, a user may make a news comment (news_cmt) accompanied by various multimedia by using the blog content input interface of his (her) own blog which (s)he is used to. 
     It is desirable that, as shown in  FIG. 5 , the news comment input interface  420  further comprises a designated blog activation selection unit  428  so that the designated blog may be activated according to the designated blog information (blog_info) when the user terminal  300  selects the designated blog activation selection unit  428 . Thus, the inconvenience that the user needs to activate his (her) blog while reading a news article to access the blog and make a blog content may be obviated. 
     A news comment (news_cmt) is closely related to the corresponding news article since the news comment (news_cmt) is posted right below the news article. On the other hand, when a news comment (news_cmt) and a blog content  510  are interconnected to each other, it is difficult for other users to understand the blog content  510  unless the news article is also posted together with the blog content  510 . To solve such problem as above when the trackback between a news article and a blog content is set up, it is preferable that the second trackback interconnecting means  130  transmits the text or URL information of the corresponding news article (news_artc_info) to the first trackback interconnecting means  230 , and the blog service providing means  210  further displays, as shown in  FIG. 3 , a news article access information  520  comprising the text or URL information of the news article in the blog content  510 . In case of the trackback from the news server  100  to the blog server  200 , the text or URL information of the news article (news_artc_info) is transmitted to the first trackback interconnecting means  230  when the trackback ping (trac_ping) is transmitted thereto. In case of the trackback from the blog server  200  to the news server  100 , on the other hand, the text or URL information of the news article (news_artc_info) is transmitted to the first trackback interconnecting means  230  when the response to the trackback ping (trac_ping) is transmitted thereto. 
     Hereinafter, a news comment outputting means  126  for providing a completed news comment to users will be explained. The news comment outputting means  126  provides a user terminal  300  with a news comment output interface  430 . The news comment output interface  430 , as shown in  FIG. 10 , may comprise a news comment list output unit  431  for outputting a list of the news comments (news_cmt), a commentator information display unit  432  for displaying at least one of the ID, personacon (personality+icon), and nickname of the user who made the news comment (news_cmt) for every each of the news comments (news_cmt), and a trackback information display unit  433  for displaying the news comment (news_cmt) for which the trackback with the blog is set up. It is desirable that the trackback information display unit  433  carries out the function to notify on the news comment list that the trackback between a specific news comment and a blog is set up, and the function to link the news comment to the blog according to the trackback as well. For example, when a user terminal  300  selects the trackback information display unit  433  by clicking, the blog to which the trackback is set up may be activated by means of pop-up or picture conversion so that a network between the news service users and the blog operators might be formed. 
     The title and contents of the news comment (news_cmt) may be inputted separately through the news comment input unit  122 , and the news comment output interface  430  may be configured to provide only a title list of the news comments (news_cmt) to the user terminal  300 , and provide the contents of the news comment (news_cmt) at the user&#39;s option. Further, the news comment output interface  430  may be configured to output only the news comments (news_cmt) for which trackbacks are set up at the user&#39;s option. 
     Hereinafter, referring to  FIG. 11 , a method for interconnecting a news and a blog by means of trackback will be explained. First, a user terminal  300  accesses a news server  100  through a communication network (S 100 ), and then the news server  100  provides the user terminal  300  with a news article and/or news comments made on the news article (S 200 ). Then, the news server  100  receives a request from the user terminal  300  for selecting the news server  100  or a blog server  200 , through which a news comment will be made (S 250 ). If the user terminal  300  makes a news comment using the news server  100 , the news comment is registered on the news bulletin board (S 320 ). Then, the news server  100  determines whether the user terminal  300  requests the trackback of the news comment (S 340 ). If so, the news server  100  transmits a trackback ping to the corresponding blog server  200  (S 400 ), and then the blog server  200  registers the news comment as a blog content (S 500 ). 
     If the user terminal  300  selects a blog server  200  to make a new comment at the S 250  step above, the news server  100  activates the user s predetermined blog thereby making the user terminal  300  connected to the corresponding blog server  200  (S 800 ). According to an embodiment of the present invention, the news server  100  transmits a news article trackback information including the URL information of the news article to the user terminal  300  before the user terminal  300  accesses the blog server  200 , so that the user might easily input the URL information of the news article to which the news comment made through the blog would be trackbacked. Next, if the user terminal  300  connected to the blog server  200  makes a news comment on the corresponding news article in the form of a blog content, the blog server  200  registers the news comment as a blog content (S 900 ). Then, the blog server  200  determines whether the user terminal  300  transmits a trackback request with respect to the news comment registered as a blog content (S 920 ). If receiving the trackback request from the user terminal  300 , the blog server  200  transmits a trackback ping to the news server  100  (S 940 ), and then the news server  100  registers the blog content on the news bulletin board (S 1000 ). 
     Referring to  FIG. 12  which shows a signal flow of the blog server  200  during the trackback interconnecting process of  FIG. 11  between the news and the blog, the trackback process at the blog server  200  will be explained in detail. As shown in  FIG. 12 , the news server  100  activates a pre-designated blog of a user, thereby connecting the user terminal  300  to the blog server  200  (S 800 ). 
     Next, as the second step, the user terminal  300  makes a news comment (news_cmt) using the blog service provided by the blog server  200 . The blog server  200  registers the news comment (news_cmt) as a blog content (S 900 ) and, as the third step, transmits a trackback request (trac_ping) to the news server  100  (S 940 ). 
     Finally, as the forth step, the news server  100  registers the news comment (news_cmt) on the news bulletin board (S 1000 ). 
     It is desirable, as shown in  FIG. 3  and unlike other general news comments, that when other users are willing to see the news comment (news_cmt) for which a trackback is set up, the blog content where the news comment (news_cmt) is made is configured to be activated immediately. For this purpose, as the fifth step, the user terminal  300  accesses the news server  100  and selects the news comment registered on the news bulletin board. And then, as the sixth step, the news server  100  activates the blog content where the news comment (news_cmt) is registered if the news comment the user terminal  300  selects has been trackbacked from the blog server  200 . As illustrated in  FIG. 3 , the news server  100  may link the title of the news comment (news_cmt) with the URL information for accessing the corresponding blog content and activate the blog content by means of pop-up or picture-conversion when the user terminal  300  clicks on the news comment (news_cmt). 
     Meanwhile, the user should be aware of the URL information of the news article to make a news comment (news_cmt) on it through his (her) blog service. For this purpose, as shown in  FIG. 12 , it is desirable that the trackback interconnecting method between the news and the blog further comprises the seventh step (S 700 ) that the news server  100  provides in advance the news article trackback information (trac_info) including the URL information of the news article on which the news comment (news_cmt) would be made, wherein the user terminal  300  further transmits the news article trackback information (trac_info) to the blog server  200  when making the news comment at the second step, wherein the blog server  200  further sends the news article trackback information (trac_info) and news comment (news_cmt) to the news server  100  when sending the trackback request at the third step (S 940 ), and wherein the news server  100  registers the news comment (news_cmt) on the news bulletin board of the corresponding news article based on the news article trackback information (trac_info) at the forth step (S 1000 ). According to this embodiment, the user may find out the URL information of the news article for trackback without any unnecessary and burdensome process. 
     It is difficult for a user who accesses the blog content without using the news server  100  to understand the blog content if the blog content contains only the news comment (news_cmt) and does not contain the news article. Thus, it is preferable that the blog content further includes the information about the news article. For this purpose, the trackback interconnecting method between the news and the blog may further comprise, after the forth step (S 1000 ), the eighth step (S 1010 ) that the news server  100  provides the blog server  200  with the text or URL information (news_artc_info) of the news article on which the news comment (news_cmt) has been made, and the ninth step (S 1020 ) that the blog server  200  further registers the link information ( 520 ) on the blog content for accessing the text or URL information (news_artc_info) of the news article. According to this embodiment, as shown in  FIG. 3 , the blog content may provide not only the news comment (news_cmt) but also the news article information. 
     Generally, a user makes a news comment (news_cmt) while reading a news article through a news service. Thus, the user is required to activate his (her) blog through another web browser to trackback the news comment (news_cmt) through the blog server  200 , which is burdensome. To solve this kind of problem, it is desirable to designate a blog as an interconnecting object and register it in the news server  100  so as to easily activate his (her) blog. For this purpose, the trackback interconnecting method between the news and the blog may further comprise the tenth step that the user terminal  300  registers the designated blog information (blog_info) including the URL information of the blog service in the news server  100 , wherein the news server  100  may be configured to activate the corresponding blog service based on the designated blog information (blog_info) at the first step (S 800 ) when the user terminal  300  connected to the news server  100  is to make a news comment. According to this embodiment, the news server  100  may enable a user to automatically access his (her) own blog without any further step therefor. 
     Next, referring to  FIG. 13  which shows a signal flow of the news server  100  during the trackback interconnecting process of  FIG. 11  between the news and the blog, the trackback process at the news server  100  will be explained in detail. 
     First, the news server  100  provides the user terminal  300  with a news comment input interface with which the user terminal  300  makes the news comment (S 300 ). At this time, if the designated blog information (blog_info) stored in the news server  100  is for a plurality of blogs, the user terminal  300  may further input the selected blog information (sel_blog_info). The user terminal  300  may further input the blog category information (blog_ctgr_info) or privilege to open information (blog_prv_info) to be set up. The user terminal  300  may further input the information for trackback of the news comment to the blog of the pressman of the news article. 
     Further, as shown in  FIG. 7 , the user terminal  300  may input the evaluation  429  of the news by selecting one of the assent, dissent, protest, and the others. According to this embodiment, since the user is compelled to carefully consider how to evaluate the news before making a news comment, it is possible to prevent deterioration of quality of the news bulletin board due to the extemporary and impulsive news comment. 
     Then, the news server  100  registers the news comment (news_cmt) inputted through the news comment input interface  420  on the corresponding news bulletin board, and, if the pressman&#39;s blog is further selected, trackbacks the news comment (news_cmt) to the pressman&#39;s blog server  200  (S 400 ). 
     Finally, the blog server  200  registers the trackbacked news comment (news_cmt) as a blog content (S 500 ). 
     According to this embodiment, the user terminal  300  may save and manage the news comment (news_cmt) made using the news server  100  in his (her) blog without being connected to the blog service. 
     It will be apparent to those skilled in the art that various modifications and variation can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
