Abstract

A method and a system for transceiving data based on metadata are provided to enable a user to input a message for exchanging information with an unspecified user smoothly/promptly on the Internet by checking property of the inputted message, and transmitting the message to the unspecified user related to the property or transmitting the information of the related unspecified user based on the checked property. A user database stores user IDs and user information corresponding to each user. A metadata obtainer(213) obtains metadata by using information received from a terminal. A database searcher searches the user IDs having the same or similar user information as all or a part of metadata among the user information stored in the user database. A transmitter transmits the received information to the users having the searched user ID or transmits the searched user IDs to the terminal. The metadata obtainer obtains the metadata by extracting a main character string from text data when the data received from the user terminal is the text data, recognizing characters or an object included in image data when the received data is the image data, and recognizing a voice included in the audio data when the received data is the audio data.

Description

Method and system for transmitting and receiving data based on metadata {METHOD AND SYSTEM FOR TRANSMITTING AND RECEIVING DATA ON THE BASIS OF META DATA}

The present invention relates to a method and a system for enabling information to be efficiently exchanged between a plurality of unspecified users, and more particularly, after the system receives input information from a specific terminal device and extracts metadata from the received input information. Searching for a user ID having the same or similar user information as the metadata and transmitting the input information to the user of the searched user ID, or transmitting the searched user ID to the specific terminal device, thereby having a common interest. A method and system are described that allow information to be exchanged more easily and immediately between users.

In addition to the widespread use of the Internet, information exchange among users on the Internet has increased dramatically. This is the development of one-man media systems, such as blogs, which have transformed Internet users into active subjects that generate content from consumers of simple content, and messenger systems that enable instant chats between remote users by directly connecting Internet users. It can be called a phenomenon caused by.

However, a conventional media system or a messenger system is insufficient to satisfy various needs of users.

First of all, in the case of the conventional messenger system, in order to designate specific users as contacts, basic information such as an e-mail address of the other party is generally required. Therefore, existing friendships are only reflected online and new relationships are formed. There is a difficult aspect. In other words, the conventional messenger system is based on limited human relations in real life, and thus means that can satisfy users if they want to interact with various people who have common interests with them regardless of their limited human relations. This situation is lacking.

In addition, in the conventional media system, when a user creates a post in a blog, the generated post is basically exposed only to the user who visits the blog, so the range of information exchange through the generated post is directly visited the blog. The disadvantage is that it is limited to users.

In order to solve these shortcomings, most blog sites provide a way to share common interests among unspecified users by providing a search service for blogs or posts, but users who have common interests using the search function Even if they can be connected indirectly, there is still a problem that it is difficult to draw a lively exchange of information and discussion of an issue because it is difficult to coincide with the points of interest of a plurality of users.

In other words, a user who writes a post on a topic on a blog has a desire to exchange information or discuss a topic as soon as the post is written. Users searching for blogs will not be able to expect an active exchange of information on the topic even if the user has a common interest, since the user will be in contact with the information of the blog on the topic only when the search related to the topic is performed.

As an attempt to solve the above problems of the prior art, Twitter Inc. For example, Twitter is an online service provided by www.twitter.com . Twitter is a web service that allows users to exchange simple answers in real time with other unspecified users on a particular topic.

Specifically, the user can enter a simple message for a specific issue using the Twitter service, the input message is posted on the Twitter site, and other users interested in the message can leave a reply to the user who wrote the message, etc. Can be. In addition, a user may provide a function of monitoring a message generated by another user by setting the other user as a follower.

Monitoring of inputs using Twitter services or messages generated by other proponents may be performed within the Twitter site, or may be performed through messenger, mobile communication, or e-mail.

For example, if a specific user enters Twitter after listening to a concert, the entered message is added to the message list on the Twitter site. In this case, the message may be notified to another user who sets the creator of the message as a supporter through a messenger, mobile communication, or e-mail. Other users who check the message can enter replies through Twitter site, messenger, mobile communication, email, etc., and the replies entered are notified to the user who wrote the message. In other words, Twitter combines the advantages of a messenger system and one-man media system to provide a service that enables an unspecified number of users to instantly exchange information on a common theme.

However, it is true that services such as Twitter provide a venue for near-real-time exchange of information between many unspecified users by posting recently entered messages on the site and providing search functions for them. There is an inefficiency of the system because it exposes the message inputted by itself to other random unspecified users, so that it can be treated as almost noise content to general unspecified majority except supporters.

In addition, even when using Twitter, users have to search for recently updated messages that match their interests, or have to check messages coming up in real time to recognize messages that match their interests. This exists. Although a message generated by a person set as a supporter has been devised, a method for notifying a user is prepared, but this is not significantly different from providing an update status of a neighboring blog using an RSS feed in an existing blog service. As a result, many people who do not set themselves as proponents want to provide informative information on the same interests, which leads to the disadvantage of not becoming a real information exchange.

Accordingly, there is an increasing need for the development of a system that helps unspecified users who are interested in a particular issue to exchange information in real time on common interests without cumbersome setting such as supporter setting.

An object of the present invention employs an advanced technical configuration compared to the above-mentioned prior art, grasps the attributes of the message input by the user, and selectively transmits the message to the unspecified user who is related to the attribute or the attribute The present invention provides a method for transmitting information about an unspecified user to the user and a system for implementing the same, so that a user who inputs a message can smoothly and immediately exchange information with an unspecified user on the Internet. .

In order to achieve the object of the present invention as described above, and to perform the characteristic functions of the present invention described below, the characteristic configuration of the present invention is as follows.

Even if the data can be extracted by searching it, it is included in the database of the present invention.

Propagation of Input Information

According to an embodiment of the present invention, the message input by the user is to increase the efficiency of message propagation by allowing the user information, such as the user's characteristics, interests, environment, etc. to be propagated to the same or similar unspecified multiple users, 4 is a flowchart illustrating this process.

Hereinafter, a process of propagating input information will be described with reference to FIG. 4.

First, the service server 200 receives input information from the terminal device 100a (S410).

However, various types of input information may exist and are not limited to specific conditions.

As the type of input information received from the terminal device 100a, the most easily conceivable is text data. The text data is a concept that generically refers to text included in an image, audio data, a video, a data file, etc. input by a user as well as text directly input by the user accessing the service server 200. For the latter example, when the service server 200 receives voice data, image data, video data, or the like, it may be assumed that the received data includes tag information in the form of text data.

As another example, when the received data is a data file executable by an application program such as an Excel file or a word file, the corresponding file may also include text data.

On the other hand, it may be assumed that text data is not included as another type of input information. For example, even voice data, image data, and video data without text data may be received as the input information of the present invention, and input information mixed with various types such as blog posts may be assumed. .

When the service server 200 receives the input information, the received input information is transmitted to the input information manager 210, and the input information manager 210 extracts metadata indicating attributes of the input information from the received input information. (S420).

In detail, metadata representing attributes of the input information may be obtained through various methods.

When the text information is included in the input information, the metadata extracted from the text data, that is, metadata indicating the attribute of the input information may be obtained from the key word.

For example, if the input information is in the form of a file, the text data of the file's name, creation time, creator, extension, etc. may be metadata indicating attributes of the input information.

In addition, the attributes of the input information may be obtained by analyzing the content of the input information and extracting a key word, which may be performed using at least one known technique based on conventional linguistic research such as a morphological analysis method and a natural language processing method. Could be. Specifically, when the input information is an image or a video, after extracting text using at least one camera-based optical character recognition (OCR) technique known in the art as a known technique for character recognition technology, natural language Meaningful keywords may be extracted and used as metadata by processing techniques and morphological analysis, and when the audio data is received, the keywords are meaningful by at least one technique known in the art for speech recognition techniques. You can also extract and use this as metadata. Specifically, examples of the known techniques for the morphological analysis method and natural language processing method, "Korean morphological analysis and information retrieval" (Kang Seung-sik, Hongneung Science Publishing, Part 2, Part 3) or G. Salton et al. The article, "Term-weighting approaches in automatic text retrieval," published in Information Processing & Management. In addition, as an example of the known technology related to the character recognition technology, "A Robust Algorithm for Text," which is written by Yangxing LIU and two others, is presented at the 8th International Conference on Document Analysis and Character Recognition (ICDAR'05). Detection in Color Images ”and the like, and an example of a known technique relating to a technique for extracting text from audio data by the speech recognition technique is a book" Robustness in Automatic Speech Recognition "by Jean-Claude Junqua et al. Fundamentals and Applications. "

For example, when a user watches a performance called A and then accesses the service server 200 to input an appreciation about the A performance, or inputs a photo taken at the A performance, the input information management unit of the service server 200. 210 may extract information about the title, performer, and the like of the A performance from the viewing contents input by the user, and give the information as metadata of the input information. It may be possible to obtain a clue to infer that the text is included in the picture taken at the performance A, and the text may be extracted by using a camera-based OCR technique, and may be given as metadata of the input information.

As another method of acquiring the attribute of the input information, when the image data is included in the input information, a method of acquiring the attribute of the input information by recognizing the shape shown in the image data can be considered.

Background Art Conventionally, research on technology for recognizing the shape of an object appearing in an image has been continuously conducted. As a related technology, a Japanese patent application filed on Jan. 14, 1995, based on Japanese Patent Application No. 1994-3333 of Denki Sangyo Co., Ltd., as a basis for claiming priority and whose name is "Shape Detection Device". Reference may be made to the invention described in 1995-566 (published as Korean Patent Publication No. 1995-23966 on August 18, 1995) and the like (the contents of Korean Patent Application No. 1995-566 are hereby incorporated by reference in their entirety). Should be considered). According to this, after photographing an object and outputting the image information, the output image information is digitized and stored as image data, the outline position of the image is determined, and the edge point of the image is detected based on the image density, A shape detection apparatus is disclosed which derives an outline as detection of edge points.

In addition, Korea, filed on July 14, 1994, entitled “Shape Detecting Method” with the name of the invention based on priority claims of Japanese Patent Application No. 1993-174134 and Japanese Patent Application No. 1993-194355 of the same applicant. Reference may be made to the invention described in Patent Application No. 1994-16927 (published as Korean Laid-Open Patent Publication No. 1995-5034 dated February 18, 1995) and the like (the contents of Korean Patent Application No. 1994-16927 are incorporated herein in their entirety). Should be considered merged). According to this, even when there is a portion where the density change is remarkable in addition to the object to be detected in the image, a shape detection method is disclosed which achieves a more accurate detection of an object in an image by dividing the image into pixel units and calculating a partial density correlation value. have.

By applying the above-described various shape recognition technology, it is possible to recognize the shape of the trademark, design, sculpture, and other objects in the image data, and to extract the information about it, and to assign the attribute obtained as metadata of the input information.

As another method of acquiring the attribute of the input information, when the input information includes image data including the face of a person, a method of acquiring the attribute of the input information by recognizing the person represented in the image data may be considered.

To this end, the system of the present invention may store the face information of each user in a user database in advance. Alternatively, the system may include a database (not shown) of face information of a predetermined person such as a movie star or a singer. Could be When input information including image data is received from the terminal device 100a, the input information manager 210 determines whether the face of the person is included in the image data. When the face of the person is detected and recognized in the received image data, by comparing the recognized person's face with the person information stored in the database, the identification information of the person included in the image data is obtained and the metadata of the input information is obtained. To be given.

As another method of recognizing a person included in the image data, there may be a method of referring to the metadata record of the image data transmitted in the past by the user who transmitted the input information. That is, when the user transmits image data including the face of the person as input information, the input information manager 210 transmits the image data about the face of the person that the user has previously sent to the service server 200 this time. When there is matching image data in comparison with image data on the face, it can be helpful to determine the metadata for the input information transmitted this time by referring to the metadata that has been given to the image data in the past. The past history of the user may be obtained from the log database 270 of the present invention.

As mentioned above, the image data includes both video content and image content. In particular, in the case of video content, both image information and audio information are included. Therefore, when metadata is extracted from video content, By using both image and audio information, more accurate and rich metadata can be extracted.

In addition, there may be various cases in which the attribute is extracted from the input information and given as the metadata of the input information.

In order to perform such an operation, the input information managing unit 210 of the present invention may include a metadata extracting unit 213 as shown in FIG. 3, and the metadata extracting unit 213 may include a voice recognition unit and a text. It may be configured to include a recognition unit, a shape recognition unit, and a face recognition unit (not shown).

In addition, in order to store the input information received from the terminal device 100a in the input information database 280 and inquire the input information stored in the input information database 280, the input information management unit 210 is the input information storage unit 211. And the input information inquiry unit 212 may be included.

When the metadata of the input information is obtained through the various procedures as described above, the obtained metadata is transmitted to the searcher 230. The searcher 230 searches for a user ID having the same or similar user information as all or part of the received metadata in the user database 260 (S430). To this end, in the user database 260, various user information about characteristics, interests, and environments of each user may be recorded for each user.

Various methods may be assumed as a method of building the user database 260 by acquiring user information about the user. As one of the methods, it may be considered that a user directly accesses the service server 200 through the terminal apparatuses 100a, 100b, ..., 100z and directly inputs information about the user.

As another method, a case may be considered in which the service server 200 obtains user information by analyzing a user's past history. That is, the content of the message sent by the user using the system of the present invention, the keyword searched by the user using the system of the present invention, the content of a specific search result selected by the user among the search results derived using the keyword, and the like. By analyzing the information, the user information about the user's characteristics, interests, and the environment can be obtained.

For example, metadata obtained by analyzing input information that has been input in the past from any user may be treated as user information for that user.

This method is not necessarily limited to the analysis of usage history for the system of the present invention, and may be extended to consider the history using services provided by other systems, for example, crawling posts registered in a user's blog. By crawling and performing a process such as "method of generating metadata from input information (S420)" mentioned above, a method of identifying user information such as characteristics, interests, and environment of a user may be assumed.

In addition, there are various ways to obtain the user information of the user, for example, in cooperation with mobile carriers, card companies, etc. to obtain a log of the user's external activities, data of the user's mobile phone, PC, etc. There may be a method of obtaining the user information by analyzing the information. That is, it is noted that the source is not limited in obtaining data for obtaining user information such as characteristics, interests, and environment of the user.

Meanwhile, when the searcher 230 obtains a list of other users having user information corresponding to the metadata of the input information input by the user, the service server 200 transmits the input information (ie, Message) (S440). In this case, the data transmitted to each of the other users may include all or part of the input information, and may include only the fact that the input information has been received by the service server 200.

At this time, the service server 200 may provide the user terminal device 100a with a user interface for selecting all or some other users from a list of a plurality of other users, and the user transmits his or her own message. Of course, you can choose what you want to do.

In addition, in transmitting a message to all or part of the other user, the message can be transmitted through at least one of an e-mail address, a messenger address, an IP address of the terminal device, a phone number, a mobile phone number, and an address. Of course, the method can be assumed.

Meanwhile, the information on the interest of the user information is information on which issue the user is interested in. The information on the interest may be obtained from log data of the corresponding user. Specifically, the log data may be obtained by analyzing the digital content created by the corresponding user by accessing the system or the external system of the present invention and the reply, the content of the comment, the creation time, and the like.

In addition, the information on the characteristics of the user information refers to information other than the information on the interests that can distinguish the user from other users, for example, the gender, specificity of appearance, unusual behavior, etc. Could be.

On the other hand, the information on the environment of the user information may be a concept such as the geographic location where the terminal device of the user exists, the terminal device 100b of other users that the user information is matched to the server 200 in step S440 ,..., 100z), the terminal device of another user who is in the same or similar environment (ie, geographical location) as the environment (ie, geographical location) to which the user of the terminal device 100a belongs, preferentially Of course, the message can be sent. As a result, it is possible to activate the information exchange between users located at close distances and to make the encounter in the online world into an off-line encounter.

The transmission of the message by the step S440 as described above may be performed in various ways, the user provided by the service server 200 if another user who is the target of the message is connected to the service server 200 of the present invention. It may be performed by using an interface, or may be performed by using an email, an SMS, an MMS, a messenger, or the like regardless of whether the service server 200 is accessed.

In another modified embodiment, when the searcher 230 obtains a list of other users who are the targets of the message transmission, the service server 200 inputs the input information instead of immediately transmitting the message to the corresponding users. It may also be assumed that the list is recommended to the user as a message transmission target, or a consent is obtained for the message transmission target.

In response, the other users who receive the message may create and transmit new input information related to the subject included in the received message. In this case, the new input information may basically be transmitted to a plurality of other users through the same process as described above. In addition, the user who transmits the new input information may have an effect similar to that of a messenger communication such as MSN by designating only the sender who has sent the message he has received as a receiver for the new input information.

Link with Search

A user may search the user database 260, the log database 270, and the input information database 280 of the present system and / or an external system by using a user interface provided by the service server 200. . At this time, a user who uses the search function may selectively request a search for some of the databases. The user may inquire the input information previously input by the user or other users by searching the input information database 280.

In addition, the user may obtain a log related to a search word input among logs performed by the user or other users in the system and / or the external system by searching the log database 270.

For example, when a user inputs a name of a specific singer as a search word, as a search result, a history of the users inputting input information for the specific singer into the service server 200, a search history for the specific singer, and A history of replies or comments on information retrieved about a particular singer may be provided.

In addition, the user may obtain a list of other users who are determined to be interested in the input search word by searching the user database 270. As such, the user may be provided with a list (or ID) of other users who have the same interests as the search results, and the contents of the digital contents, replies, and comments made by the searched other users may also be provided. Of course, it can be provided as a search result corresponding to each.

A user can input and send a message to them by specifying some or all of the above-mentioned list of other users. This is similar to the process of acquiring a list of users deemed interested in the above-described input information and transmitting a message. Through this process, information exchange and intention is freely made with other users who have the same interests as those of the unspecified majority. Since the exchange can be achieved, it is possible to implement a so-called advanced messenger.
