Abstract

A system and a method for managing contents based on a semantic ID of a tag are provided to remarkably reduce time/effort needed for checking unwanted contents and searching again the contents of the tag or a synonym by preventing the tag corresponding to the unwanted meaning from searching, and searching the contents having other tags corresponding to the same meaning. An SM database server(10) assigns a meaning ID to each meaning of a word to recognize the word having more than one meaning and the meaning of the word, and managers the meaning ID. A content management server(20) manages contents. A user terminal receives a tag from a user, forms an RTAG by obtaining the meaning ID of the tag from the SM database server through the contents management server, and tags the RTAG to the contents, and transfers the contents tagged by the RTAG to the contents management server. The content management server receives and manages the contents tagged by the RTAG.

The present invention relates to a content management system and method for managing content based on a semantic identifier of a tag. More specifically, the present invention relates to a semantic identifier of a tag that enables a user to search for a content corresponding to a desired tag. A content management system and method for managing content.

Recently, in the era of Web 2.0, tagging sites that allow users to directly add tags in the form of keywords to content they want to share are emerging. Such a tagging site allows a user to add a tag to content such as a bookmark, a photo, a video, and the like, and classifies the content using a tag, thereby allowing the user to search for the content using the tag. The method of classifying content according to the tag input by the user is called folksonomy.

One such tagging site is Flickr (http://flickr.com), which provides users with images uploaded by over half a million members. Flickr categorizes images by tag, using tags as a tool for users to describe the images. By using tags when members upload images or when users search for images, it makes it easier for users to search for images on a particular subject.

However, tagging sites, including Flickr, are often unsatisfactory in search results when classifying contents according to tags.

The dissatisfaction with the search results currently used in tagging sites can be attributed to the uncertainty in the meaning of the terms used as tags. Because users are the input subjects of a tag, the tag is ambiguous and has a noticeable personality. Most tagging sites do not manage singular or plural forms of English words used as tags or tags formed with compound words. Special tags, nonsensical tags that are only used in specific groups, and tags that are extremely private and cannot be shared, will not be found or appear in the results of a search for a tag at all. In particular, when a term used as a tag has a plural or synonym having a plurality of meanings, the present tagging system cannot process synonyms and synonyms of a tag, so that the search result may be different from the result desired by the user.

In more detail, when a tag is a multiword, each meaning of the tag may belong to an unrelated field. In this case, a user must repeat a meaningless click to find a desired content even in a search result obtained by inputting a desired tag. For example, the tag 'apple' has both the meaning of fruit and the meaning of Apple Computer, so that the content of the fruit and the content of the computer are searched in the search results. Therefore, when the user searches for apple as a fruit, the content on the computer is meaningless to the user, and it becomes an obstacle to quickly find the desired content.

Also, when tags have synonyms, each user will use different words to express the same concept. Therefore, when searching, the user should search for all synonyms that have the concept. For example, 'mac', 'macintosh', and 'apple' can all be used to represent content related to an Apple macintosh computer, and each word is recognized as a different word when searching for content. Each must be searched. Therefore, the search time is long, and if the user does not input all the synonyms, the desired content may not be found.

Flickr, on the other hand, provides clusters that group similar tags together into related tags, and uses co-occurrence, the frequency with which tags are used together to group them. For example, Turkey means, according to WordNet, algae, food, country, people, and failures, but the clusters that Flickr provides for Turkey are shown in the following image.

Here, images tagged with Turkey and 'stuffing' are included in a food-related cluster, and images tagged with Turkey and 'mosque' are included in a cluster related to a country. Since the plurality of clusters are only classified according to the frequency of appearing together, it is not easy for the user to predict which cluster the desired image belongs to.

Clusters are also used to resolve the ambiguity of tags, which means that more than one tag must exist to form a cluster. In other words, if the tag is made up of only Turkey, it is not included in any cluster and thus is not searched.

In addition, classification by clusters does not allow synonyms to belong to the same cluster, and it is difficult to find similarities between tags through the relationship between clusters because the tags are grouped based on which tags are used and how often.

As such, in existing tagging systems, due to the uncertainty of the tag, not only the content desired by the user but also irrelevant content may be displayed as a search result, or in order to search for the desired content, all synonyms should be searched to find the desired content. It takes a relatively long time and requires the user's hard work.

Accordingly, a tag having multiple meanings and a synonym of a tag should be classified so that a user can quickly and accurately find a desired content.

Accordingly, it is an object of the present invention to provide a content management system and method for managing content based on semantic identifiers of tags that enable a user to quickly and accurately search for desired content.

In order to achieve the above object, the configuration of the present invention provides a word having a meaning of at least one meaning and a meaning identifier (hereinafter referred to as "MID") for each meaning of the word in order to identify the meaning of the word. Receiving a tag from an SM database server managing the content, a content management server managing content, and a user, and obtaining an MID of the tag from the SM database server via the content management server to configure an RTAG. And a user terminal for tagging content and transmitting the tagged content to the content management server, wherein the content management server manages the content tagged with the RTAG transmitted from the user terminal.

On the other hand, in configuring the RTAG, the user terminal inquires of the content management server what the MID of the tag received from the user, and the content management server is the MID of the tag inquired by the user Query the SM database server, the SM database server retrieves the MID of the tag inquired by the content management server, generates a MID list, and transmits the generated MID list to the content management server, and the content management server transmits the MID list to the user terminal. The user terminal may display the MID list to the user, select one MID from the user from the user, and configure an RTAG with the selected MID.

Further, in configuring the RTAG, the user terminal inquires of the content management server what the MID of the tag input from the user is, and the content management server determines what the MID of the tag inquired by the user is. Querying the database server, the SM database server searches for the MID of the tag inquired by the content management server, generates an MID list, and transmits the generated MID list to the content management server, and the content management server sends the MID list to the user terminal. The user terminal may display the MID list to the user, select one MID from the user from the user, and configure the RTAG with the selected MID and a tag input from the user.

Meanwhile, in configuring the RTAG, the user terminal inquires of the content management server what the MID of the tag input from the user is, and the content management server corresponds to the MID of the tag inquired by the user and the MID. Ask the SM database server what MID MEANING is, the SM database server searches for the MID of the tag inquired by the content management server, generates a MID list and a MID MEANING list, and sends the MID MEANING list to the content management server. The content management server transmits the MID list and the MID MEANING to the user terminal, and the user terminal displays the MID MEANING list to the user, receives one MID MEANING from the MID MEANING list, and receives the selection. RTAG can be configured with MIDs and tags corresponding to MID MEANING.

In addition, the user terminal may display a MID MEANING list of the tag and provide a screen from which one of the MID MEANINGs may be selected to receive the MID MEANING from the user.

Meanwhile, the user terminal displays a screen having a blank for receiving a tag from the user and a "browse multilingual" button for searching for a multilingual word of a tag input to the blank, and the user tags the blank. If the user inputs and selects the " multilingual search " button, the user terminal can inquire the content management server of what the MID of the tag received from the user is.

The content management server includes a content database server and a MID SET processing unit. The user terminal inquires of the MID SET processing unit what the MID of the tag input from the user is, and the MID SET processing unit inquires of the user. The SM database server inquires about the MID of one tag and the MID MEANING corresponding to the MID, and the SM database server searches for the MID of the tag inquired by the MID SET processing unit to generate a MID list and a MID MEANING list. The MID SET processing unit transmits the MID list and the MID MEANING to the user terminal, and the user terminal displays the MID MEANING list to the user, and the user selects one of the MID MEANING lists from the user. RID is composed of MID and tag corresponding to selected MID MEANING by user's MID MEANING It said, by tagging the RTAG the content and sends it to the content database server, and the content database, the server can control the content of the RTAG transmitted from the user terminal tagging.

Meanwhile, the user terminal additionally receives a search tag for searching for content from a user, and inquires of the content management server what is the MID of the search tag received, and the content management server inquires of the user. The SM database server inquires of the MID of the search tag and the MID MEANING corresponding to the MID. The SM database server searches for the MID list and the MID MEANING by searching the MID of the search tag inquired by the content management server. A list is generated and transmitted to the content management server, and the content management server transmits the MID list and MID MEANING to the user terminal, and the user terminal displays the MID MEANING list, from the user in the MID MEANING list. One MID MEANING is selected by the user, and the MID corresponding to the selected MID MEANING To search for tags by configuring and RTAG forwards the RTAG to said contents management server, the content management server may transmit a result of searching the content tagged by the RTAG transmitted from the user terminal to the user terminal.

The content management server includes a content database server and a MID SET processing unit. The user terminal inquires of the MID SET processing unit what the MID of the search tag input from the user is, and the MID SET processing unit is a user.

In order to achieve the other object of the present invention, the configuration of the present invention,

The first step of assigning an identifier (hereinafter referred to as "MID") for each meaning of the word to identify the word having at least one meaning and the meaning of the word, and managing the content in the database. A second step of managing, a third step of obtaining an MID of a tag input from a user from the database of the first step and configuring an RTAG, and a fourth step of tagging the RTAG to content and managing the database in the second step It includes.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

When the tag is a multiword, the content management system classifies and manages the content according to its meaning, so that only the content desired by the user at the time of retrieval is accurately searched.

1 is a functional block diagram of a content management system according to an embodiment of the present invention.

The content management system is a synonym and polysemy database server 10 (hereinafter referred to as an "SM database server") that classifies and manages words by meaning, and upload and download contents. It includes a content management server 20 for classifying and storing the content management server 20, and a user terminal (1) for uploading the content to the content management server 20 or search for and download desired content from the content management server 20.

Here, the SM database server 10, the content management server 20, and the user terminal 5 are mutually connectable through the network networks 3a and 3b. The network 3a may be a wide area network, a local network, a wired network, a wireless network, an internet network, a mobile communication network, or a data communication network, and the network 3b may also be a wide area network, a local network, a wired network, a wireless network, or the Internet. Network, mobile communication network, or data communication network. In the embodiment of FIG. 1, the content management server 20 and the SM database server 10 are separated and configured to be interconnected through the network 3b, but the SM database server 10 and the content management server 20 are configured. ) Can be physically implemented as a single server.

The SM database server 10 will be described.

The SM database server 10 according to an embodiment of the present invention manages a semantic identifier called MID (Meaning Identification) assigned to each word together with the word. At least one MID is assigned to a word. For example, when a word is a multiword having various meanings, a MID is assigned for each meaning. If a word has four meanings, the word has four identifiable MIDs. As used herein, "managing" means at least one of storing, updating, deleting, maintaining, retrieving, moving, and / or copying data.

The words stored by the SM database server 10 may be English, Korean, Chinese, French, German, or Japanese, but are not limited thereto. The words stored by the SM database server 10 are used interchangeably with the term "tag" herein. Information input by a user for the purpose of tagging the content or for searching the content is referred to as a "tag". Since the "tag" will mainly be in the form of a word, it is used herein to mean the same thing except when it is necessary to strictly distinguish between "tag" and "word".

On the other hand, when it is necessary to distinguish between the information input by the user in order to search the content and the information input by the user for the purpose of tagging the content when the content is stored, the former is particularly referred to as a "search tag", The latter is referred to as the "tag." However, when there is no real advantage to distinguish both, they are used interchangeably with the term "tag".

The word managed by the SM database server 10 may have only one meaning or may be a multi-word having multiple meanings. Here, the multiword is classified according to a plurality of meanings, and an MID that is an identification code is assigned to each of the plurality of meanings.

In the case of the word Turkey, for example, Turkey has five meanings: Turkey as a bird, Turkey as a country, people, cooking, and failure. The SM database server 10 according to an embodiment of the present invention assigns and manages different MIDs for these five meanings. In other words, Turkey has five MIDs.

On the other hand, the SM database server 10, in the words to be stored among the words that are spelled different from each other but the same meaning, the same MID is assigned to manage.

For example, suppose Turkey as a bird is given a MID of 10177 and Turkey as a country is assigned a MID of 10891, and MIDs of 10345, 10654, and 10585 are assigned to each person, dish, and failure. Assume Meanwhile, as shown in FIG. 4, 'Melegaris gallopavo' is a synonym for Turkey as a bird, and according to the above assumption, the MID of 'Melegaris gallopavo' becomes 10177. That is, the MIDs of Turkey as a bird and 'Melegaris gallopavo' are the same as 10177.

In this example, the SM database server 10 may manage Turkey and Melegaris gallopavo, as shown in Table 1.

word MID Turkey 10177 Turkey 10891 Turkey 10345 Turkey 10654 Turkey 10585 Melegaris gallopavo 10177

As can be seen in the above example, the SM database server 10 according to an embodiment of the present invention manages the MID together with the word.

The SM database server 10 additionally manages the meaning of MID.

For example, the SM database server 10 may manage what MID 10177 means as follows.

Turkey: 10177: large gallinaceous bird with fan-shaped tail, widely domesticated for food

In the present specification, the meaning of a specific MID is used as the term "MID MEANING". In the above example with MID 10177, MID MEANING points to "large gallinaceous bird with fan-shaped tail, widely domesticated for food."

The content management server 20 according to an embodiment of the present invention inquires the SM database server 10 of what the MID of the tag is. Here, the "MID of the tag" means "MIDs respectively assigned to various meanings of the tag". In response to the inquiry of the content management server 20, the SM database server 10 searches for all MIDs that the tag has, and the search result (hereinafter referred to as "MID list") to the content management server 20. send. According to one embodiment of the present invention, if the tag is multiword, a plurality of MIDs are retrieved. Preferably, when transmitting the MID list to the content management server 20, the SM database server 10 transmits the meanings of each MID (hereinafter, referred to as "MID MEANING list") together.

For example, if the content management server 20 sends a "Turkey" tag to the SM database server 10 and inquires about the MID, the SM database server 10 may request Turkey to have MID lists 10177, 10891, 10345, 10654, 1058 is transmitted to the content management server 20.

Preferably, SM database server 10 transmits MID list and MID MEANING LIST to content management server 20 together. For example, when the content management server 20 inquires of the MID while sending a "Turkey" tag, the SM database server 10 transmits the information shown in Table 2 to the content management server 20.

MID meaning 10177 Birds 10891 country 10345 Person 10654 Cooking 10585 clinker

The content management server 20 will now be described.

The content management server 20 manages the content transmitted from the user terminal 5 and the MID. When the content request is received from the user terminal 5, the content management server 20 searches for the requested content and transmits the requested content to the user terminal 5.

The content management server 20 manages the following information, for example.

The name of the image file MID IMAGE 1 10177 IMAGE 2 10891 IMAGE 3 10345, 18976 IMAGE 4 10654 IMAGE 5 10177

The content upload operation of the content management server 20 will be described.

The user terminal 5 transmits the tag input by the user to the content management server 20.

The content management server 20 transmits the tag transmitted by the user terminal 5 to the SM database server 10, and requests that all MIDs and MID MEANING corresponding to the MID of the tag are sent. The SM database server 10 retrieves all MIDs and respective MID MEANINGs of the tag, and transmits the MID list and the MID MEANING list to the content management server 20.

The content management server 20 which has received the MID list and the MID MEANING list from the SM database server 10 transmits the MID list and the MID MEANING list to the user terminal 5. The user terminal 5 displays the MID MEANING list to the user (since MID is a kind of code, it is easy for the user to display the MID MEANING list to the user) and receives one of them.

The user terminal 5 forms an RTAG (hereinafter referred to as "RTAG") based on the MID MEANING selected by the user, tags the content with the RTAG, and transmits the content to the content management server 20. . Here, the RTAG is i) "MID" corresponding to the MID MEANING selected by the user, or ii) "MID SET" consisting of a MID corresponding to the MID MEANING selected by the user and a tag input by the user.

In the present specification, RTAG is to be used strictly apart from terms such as "tag" or "tag" or "Tag". That is, "RTAG" means that the content managed by the content database server 35 is actually tagged or to be tagged in the future. Mainly, the user terminal 5 generates and transmits it to the content database server 35. An example of the RTAG is "MID" or "MID SET". Here, "MID SET" means composed of "MID: tag". The MID constituting the RTAG may be input from a user or may be obtained from the SM database server 10. In addition, the tag constituting the RTG may be input from the user, or may be obtained from the SM database server 10.

The content management server 20 tags and manages RTAGs on content in response to the transmission operation of the user terminal 5.

Now, the content search operation of the content management server 20 will be described.

The user terminal 5 transmits a search tag (or MID) to the content management server 20 to find desired content.

The content management server 20 inquires the SM database server 10 to obtain the MID of the search tag. When the MID list and the MID MEANING list come from the SM database server 10, the content management server 20 transmits the MID list and the MID MEANING list to the user terminal 5. The user terminal 5 selects one MID MEANING from the MID MEANING list transmitted from the content management server 20 and configures the RTAG. Specifically, the user terminal 5 configures the RTAG with the MID corresponding to the MID MEANING selected by the user, or configures the RTAG with the MID corresponding to the MID MEANING selected by the user and the search tag input by the user. Thereafter, the user terminal 5 transmits the RTAG to the content management server 20.

The content management server 20 searches for the content with the RTAG received in response to the transmission operation of the user terminal 5 and transmits it to the user terminal 5.

In an embodiment of the download operation, variations are possible.

That is, when only one MID comes from the SM database server 10 when the content management server 20 queries the MID, the content management server 20 queries the user terminal 5 for MID and selects the MID. It is also possible to configure the MID to retrieve the tagged content and transmit it to the user terminal 5 without performing the procedure.

2 is a functional block diagram of a content management system according to an embodiment of the present invention.

Referring to FIG. 2, the content management system includes a user terminal 5, a content management server 20, and an SM database server 10, and the content management server 20 includes a content database server 35 and a MID processing unit. (34).

The overall operation of storing the content in the content management server 20 will be described. The user terminal 5 receives a tag (or MID) from the user, and the user terminal 5 configures an RTAG using the tag (or MID) input from the user, and the content is stored in the content management server 20. The RTAG is tagged and transmitted to the content management server 20.

The overall operation of searching for content stored in the content management server 20 will be described. The user terminal 5 receives a search tag (or MID) from the user, and the user terminal 5 constructs an RTAG based on the search tag (or MID) input from the user, and sets the RTAG to the content management server. The content management server 20 searches for all the content tagged with the received RTAG, and then transmits the search result to the user terminal 5.

 The operation of the content database server 35 and the MID SET processing section 34 will now be described in detail.

The content database server 35 manages the RTAG and the content uploaded (transmitted) from the user terminal 5. Here, the content may include various types of data that can be shared on a network, and may include, for example, a video, an image, a music file, and a dictionary. The RTAG managed by the content database server 35 is MID or preferably MID SET.

 The content database server 35 manages to search for content by RTAG. The content database server 35 according to an embodiment of the present invention assigns and manages at least one RTAG to content.

For example, when uploading content for Turkey as a bird from the user terminal 5, the content is given a MID of 10177 and managed by the content database server 35. Preferably, the content database server 35 manages MID SET of Turkey: 10177 in correspondence with the content.

When the MID SET processing unit 34 inquires "What is the MID of a tag" from the user terminal 5, it inquires the SM database server 10 of all MIDs and MID MEANINGs corresponding to the tag. The SM database server 10 searches for the MID corresponding to the tag inquired, prepares the MID list and the MID MEANING list, and sends them to the user terminal 5. The user terminal 5 displays the MID list (or MID MEANING list) received from the MID SET processing unit 34 to the user, selects one MID (or MID MEANING) from the user, configures an RTAG, and forms the RTAG. Is tagged to the content to be uploaded and transmitted to the content database server 35.

5, 6, and 7, operations of the user terminal 5, the content database server 35, and the MID SET processing unit 34 when uploading content will be described.

5 is a screen of an upload window provided to a user terminal when uploading content, FIG. 6 is a screen displaying a tag meaning according to an embodiment of the present invention, and FIG. 7 is an upload according to an embodiment of the present invention. This is a window screen.

5 is an example of a screen of an upload window provided to a user terminal when uploading content. The user selects the content to upload by using the "Browse" button at the bottom of the prompt "Find the image (s) you want on your computer" on the screen of FIG. 5, and inputs a tag for searching for the content. You can fill in the blank at the bottom of the prompt under "Your Tag or MID". In the blank, for example, a word may be entered, for example, "turkey", or a MID may be directly entered.

Entering "turkey" as shown in Fig. 5, and pressing the "Browse Synonym" button, the MID MEANING list for "turkey" is displayed as shown in Fig. 6. When the user checks one of the meanings shown in FIG. 6 and selects the "SELECT" button, a screen as shown in FIG. 7 may be displayed. Now when the user selects the "UPLOAD" button, the RTAG is tagged with the content and sent to the content database server 35. In this example, the RTAG is "turkey: 10177".

In response to the user selecting the " multilingual search " button, the user terminal 5 inquires of the MID of the tag to the MID SET processing unit 34, and the MID SET processing unit 34 sends to the SM database server 10. The MID and MID MEANING of the Tag are inquired and returned, and the result of the reply is sent to the user terminal 5.

The user terminal 5 may display the returned result to the user in the form of a screen as shown in FIG. 6. When the user selects one MID MEANING on the screen of FIG. 6 and selects the "SELECT" button, the screen shown in FIG. 7 is displayed. When the user presses the "UPLOAD" button on the screen of FIG. 7, the user terminal 5 transmits the content and the RTAG (i.e., MID or MID SET) to the content database server 35. FIG.

The content database server 35 manages by tagging the received RTAG to the content. In this example, although the user terminal 5 inquires the MID of the tag to the MID SET processing unit 34, and the MID SET processing unit 34 returns the MID and the MID MEANING, the user terminal 5 sets the MID SET. It is of course possible to configure the processing unit 34 to query the MID and MID MEANING of the Tag and the MID SET processing unit 34 to return the MID and MID MEANING.

The upload operation when the user knows the MID of the tag will now be described.

The user can directly input the MID on the screen as shown in FIG. 5 displayed by the user terminal 5. When the user directly inputs the MID and selects the UPLOAD button, the user terminal 5 transmits the RTAG and the content to the content database server 35 in response to the user's operation. In this case, the RTAG is composed of the MID input by the user.

Alternatively, when the user inputs the MID and selects the UPLOAD button on the screen as shown in FIG. 5, the user terminal 5 may display the screen as shown in FIG. 8. In the screen of FIG. 8, when the user selects one tag (in this example, turkey) and selects "SELECT", a screen similar to that of FIG. 7 is displayed (blank is displayed in the MEANING OF Tag column), and the user again. If the " UPLOAD " button is selected, the user terminal 5 transmits the RTAG composed of the MID SET to the content database server 35 by tagging the content. When the user terminal 5 displays the screen as shown in FIG. 8, when the user inputs the MID and selects the UPLOAD button, the user terminal 5 sends the tag information corresponding to the MID to the MID SET processing unit 34. Ask to be sent. Upon receiving the request of the user terminal 5, the MID SET processing unit 34 requests the SM database server 10 to send Tag information corresponding to the MID, receives a reply, and returns the response to the user terminal 5. Thereafter, the user terminal 5 displays the reply result as shown in FIG.

On the other hand, if the user directly enters the MID on the screen of FIG. 5 and selects the "browse multilingual" button before selecting the "UPLOAD" button, the MID MEANING of the input MID may be displayed on the user terminal 5. . The user will then be able to verify that the correct MID has been entered. For example, if the user inputs "10891" on the screen of FIG. 5 and selects the "Browse multilingual" button, the screen as shown in FIG. 9 may be displayed by the user terminal 5.

Fig. 9 shows that the tags that can correspond to the case where the MID is "10891" are "turkey" and "Republic of turkey", and the MID MEANING indicates "country". The user can check the screen of FIG. 9 to confirm that the desired MID is correctly described. When the user presses "SELECT" in FIG. 9, the screen shown in FIG. 7 is displayed again. When the user selects "UPLOAD", the MID SET whose MID is 10891 and the tag turkey is tagged to the content, and the content database server 35 Is sent. The content database server 35 manages by tagging MID SET 10891: turkey to the received content.

When the user enters 10891 on the screen of FIG. 5 and presses the "multilingual search" button, the user terminal 5 inquires of the MID SET processing unit 34 for MID MEANING corresponding to MID 10891, and the MID SET processing unit 34 ) Inquires into the SM database server 10 for the MID MEANING of the MID 10891 and the words belonging to the MID, receives the reply result, and transmits the result to the user terminal 5. The user terminal 5 which has received the reply result displays the screen shown in FIG. 9 to the user.

10 and 11, the operations of the user terminal 5, the content database server 35, and the MID SET processing unit 34 during content search will be described.

10 is an example of a content search screen provided to the user by the user terminal 5. For example, if a user wants to search for content tagged with turkey, enter turkey and select "Find a word". As a result of the selection, the user terminal 5 displays all MID MEANING which turkey has as shown in FIG. If the corresponding MID MEANING is selected among the MID MEANINGs displayed on the screen, the user terminal 5 may additionally display the screen as shown in FIG. 11 to the user. Of course, the search result screen of FIG. 12, which will be described later, may be immediately displayed to the user without displaying the screen as shown in FIG.

In FIG. 10, when the user enters turkey and selects "search for words", the user terminal 5 inquires of the MID SET processing unit 34 to send all MIDs owned by "turkey", and the MID SET processing unit ( 34) inquires into the SM database server 10 for all MIDs and respective MID MEANINGs of the tag turkey, and sends a reply to the user terminal 5. The user terminal 5 receiving the reply result displays a screen as shown in FIG. In the screen of FIG. 6, when the user selects the desired meaning, the user terminal 5 displays the screen as shown in FIG. 11, and when the user selects the "CONFIRM" button, the RTAG (MID or MID SET) is selected. Transfer to the content database server 35. On the other hand, in this example, when the user selects the desired MID MEANING on the screen of FIG. 6, the user terminal 5 immediately enters the RTAG (MID or MID SET) without displaying the screen as shown in FIG. 35 can be sent. In this example, the user terminal 5 inquires the MID of the Tag to the MID SET processing unit 34, and the MID SET processing unit 34 returns the MID and the MID MEANING. The MID SET processing unit 34 may inquire of the MID and MID MEANING of the tag, and the MID SET processing unit 34 may of course return the MID and the MID MEANING.

The content data server 35 receiving the RTAG (MID or MID SET) searches for content tagged with the same RTAG as the received RTAG, and transmits the search result to the user terminal 5. The user terminal 5 displays the received result to the user. An example of the search results displayed to the user is shown in FIG.

For example, when a user searches for Turkey as a bird, as shown in FIG. 12, all contents corresponding to MID 10177 are fetched and displayed. In this case, the description of Turkey as a bird and the synonym 'Melegaris gallopavo' 'Together.

According to another embodiment of the present invention, the content management system may further include a web server (not shown) and a web browser when the networks 3a and 3b are the Internet network. The web server and web browser technologies are well known technologies for exchanging web pages through the Internet, and thus will not be described in detail. Those skilled in the art will be able to implement various content management systems according to the characteristics of the network.

A process of uploading content in the content management system will be described with reference to FIGS. 2 and 13 as follows.

The user terminal 5 receives the content to be uploaded and a tag to be tagged into the content from the user (S1200). The MID SET processing unit 34 inquires of the MID of the tag, and the MID SET processing unit 34 The tag received from the user terminal 5 is transmitted to the SM database server 10, and the MID and MID MEANING of the tag are inquired. The SM database server 10 searches for all MIDs of the inquired tag (S1210), and transmits the searched MID list and the MID MEANING list to the MID SET processing unit 34, and the MID SET processing unit 34 receives the received search. The result is sent to the user terminal 5. The user terminal 5 displays the MID MEANING list to the user (S1220), receives one MID MEANING from the displayed MID MEANING list from the user (S1230), and inputs the tag input in S1200 and the MID MEANING selected in S1230. The RTAG is configured with a corresponding MID, and the RTAG is tagged to the content to be uploaded and transmitted to the content database server 35. The content database server 35 manages the received content and the RTAG by tagging each other (S1240).

Now, a process of searching for content in the content management system will be described with reference to FIGS. 2 and 14.

The user terminal 5 receives the search tag from the user (S1300), and inquires of the MID SET processing unit 34 what the MID corresponding to the search tag is, and the MID SET processing unit 34 sends the user terminal 5 MID and MID MEANING of the search tag are inquired while transmitting the search tag received from the " The SM database server 10 searches for all MIDs of the inquired search tag (S1310), and transmits the searched MID list and the MID MEANING list to the MID SET processing unit 34, and the MID SET processing unit 34 transmits. The received search result is sent to the user terminal 5. The user terminal 5 displays the MID MEANING list to the user (S1320), receives one from the displayed MID MEANING list from the user (S1330), and responds to the search tag input in S1300 and the MID MEANING selected in S1330. The RTAG is configured with the MID to be transmitted, and the RTAG is transmitted to the content database server 35. The content database server 35 searches for all content tagged with the same RTAG as the received RTAG (S1340) and transmits it to the user terminal 5. In this step, the content database server 35 may transmit the searched list to the user terminal 5. The user terminal 5 displays the searched list to the user (S1350).

 In order to verify the efficiency of the content management system according to an embodiment of the present invention, the following two experiments were performed. Table 4 shows the search results when the tags are classified in the cluster form in the existing Flickr site, and Table 5 shows the search results in the content management system.

Turkey Flickr Clusters Cluster images Flickr images Bird Food or bird related 1,200 unknown Food Location Location related 1,200 unknown Scenery related 1,200 unknown Turkish related 1,200 unknown Person No cluster unknown unknown event No cluster unknown unknown Total 4,800 305,175

As shown in Table 4 above, on the Flickr site, the tag Turkey is classified into four clusters related to food and bird, location, landscape, and Turkish, and 1,200 images correspond to each cluster. have.

The first column in Table 4 shows the multiple meanings of Turkey used in this content management system for comparison.

In the existing Flickr site, when searching for images of birds, 1,200 images are searched even if you select a food and algae cluster, so the user must view 1,200 images to find the desired image. And since there are no clusters related to people or events, the user has to look at 4,800 images to find the desired image.

Turkey sysnonym No. of images Query results Bird Turkey 200 300 Meleagris gallopavo 100 Food turkey 200 200 Location Turkey 200 300 Republic of Turkey 100 Person turkey 200 300 joker 100 event turkey 200 400 bomb 100 dud 100 Total 1,500 1,500

In this experiment, the content tag is set to Turkey, 200 contents are tagged and stored for each meaning of Turkey, and 100 images are prepared for each synonym. Thus, the experiment was performed in a state where 1,500 contents were formed.

If a user wants to search for Turkey as a bird, 200 contents tagged with Turkey and 100 contents tagged with Meleagris gallopavo are searched out of a total of 1,500 contents. That is, when the user views 300 contents, the user may find desired contents.

In particular, if a user wants to find content related to Turkish people or events, the user only needs to look at 300 and 400 contents, respectively. This means that 1,200 and 1,100 pieces of irrelevant content do not need to be reviewed among 1,500 pieces of content, thereby significantly reducing the user's search time and effort.

As such, the content management system classifies the multiple meanings of the tags separately and groups the synonyms together so that the user can search exactly the content desired by the user only by inputting a tag and selecting one of the multiple meanings. Can be.

As described above, according to the present invention, when a desired tag has multiple meanings, the user may be prevented from searching for a tag having a meaning other than the desired meaning, and the contents of other tags having the same meaning may be searched together. This can dramatically reduce the time and effort required to look at unwanted content or re-search the content of tags and synonyms.

Further, in the detailed description of the present invention, specific embodiments have been described, which should be taken as exemplary, and various modifications may be made without departing from the technical spirit of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the claims below, but also by those equivalent to the claims.
