1 is a view for explaining a content-corresponding information providing system according to an embodiment of the present invention.

As shown in FIG. 1, the content-corresponding information providing system according to an embodiment of the present invention may include a plurality of user terminals 100 and an information providing server 200. Here, 'terminal' and 'server' are a collection of hardware and software that can be interlocked for a specific purpose regardless of physical location and specific configuration. Each component can be interconnected via a network.

The first and second user terminals 110 and 120 are connected to the information providing server 200 and can transmit and receive messages between the user terminals 100 through a chat window provided by an instant messenger or the like, Or the like provided by the user.

Although the first and second user terminals 110 and 120 are illustrated in the present embodiment, the number of the user terminals 100 and the number and the status of the dialog windows formed by the user terminal are not limited to the illustrated example, The user terminal 100 can be used and a plurality of user terminals can send and receive messages in one dialogue box and send and receive messages in one or more dialogue windows of one or more user terminals 100 have.

In addition, the user terminal 100 can transmit and receive contents through a chat window, and the user terminal 100 can be a personal computer, a mobile communication terminal, a smart phone, a tablet PC, a smart TV, an MP3 player , A PMP, an electronic notebook, and the like. However, the user terminal of the present invention is not limited to this, and there is no limitation as to the form and the type of advertisement information provided by the information providing server 200 if the advertisement information provided by the information providing server 200 can be received through an instant messenger program or a chat program. For the sake of convenience, in the following embodiments, the case where the user terminal 100 is a smart phone will be described as an example.

When the predetermined content is posted in a dialog window formed by the user terminal 100 by way of input or selection, the information providing server 200 displays a sentence of content transfer based on the point of time when the corresponding content is used in the dialog window, A keyword is selected according to the frequency of use of the extracted keyword, the selected keyword is generated as metadata of the corresponding content, the corresponding keyword is stored in association with the corresponding content, and information related to the metadata, such as advertisement, 100).

When the information provided by the information providing server 200 is an advertisement, the information providing server 200 may include at least one of a text advertisement, an image advertisement, an Internet link, a video advertisement, and product information.

The advertisement information related to the content may be provided to the user terminal 100 using the content, or may be provided to a designated user. In addition, the information associated with the content may be variable. Specifically, when the metadata corresponding to the content, that is, the keyword, is changed, the information related to the changed keyword may be provided, or even if there is no keyword change, the most suitable information at that time may be retrieved or extracted have.

The process of extracting keywords from the conversation contents related to the contents will be described later with reference to FIG. 3 to FIG.

2 is a diagram for explaining a configuration of a content correspondence information providing server according to an embodiment of the present invention. The information providing server 200 according to the present embodiment includes a keyword extracting unit 210, a metadata generating unit 220, a database 230, a control unit 240, a communication unit 250, and an information providing unit 260 can do.

Here, the keyword extracting unit 210 collects one or more words used in conversations in a predetermined range of the dialog window, and for example, calculates a plurality of upper (lower) words in descending order of frequency of use For example, 1 to 4 words) can be selected as a keyword for the corresponding image.

The collection of words may be performed in such a manner that the words are collected from the words used in a few previous sentences or a few sentences based on the point in time when the contents were used. For example, in a plurality of dialog windows, words used in the previous sentence and the following three sentences are individually extracted based on the point in time when the specific content is used, and the frequency of use of the words is summed up. Can be extracted by a keyword.

The process of collecting a word and extracting a keyword therefrom may be performed based on only one dialog window, or a keyword may be extracted by combining words used in a plurality of dialog windows.

In the exemplary embodiment of the present invention, the content is an image. However, the content is not limited to an image but may be a moving image, a music file, an audio file, or the like.

The collection of the words used in the dialog window may be accomplished through matching of the word database stored in the keyword extracting unit 210.

The metadata generation unit 220 performs a function of setting a keyword extracted from the keyword extraction unit 210 or a related concept to metadata of the corresponding image. Accordingly, if the image in which the metadata is set is later used again in the same or another dialog window, it is possible to provide information such as an advertisement related to the metadata set in the image.

The database 230 functions to store metadata corresponding to images and images. The metadata stored in the database 230 is also changed when the keyword related to the image is changed.

The control unit 240 controls the overall operation of the internal components of the information providing server 200 and the communication unit 250 transmits and receives data to and from the user terminal 100. The communication unit 250 may be connected to the user terminal 100 through a wireless connection or a wired connection method such as a WLAN (Wireless Local Area Network), a WiFi (Wireless Fidelity), a WiMAX (Worldwide Interoperability for Microwave Access) have.

The information providing unit 260 provides the user terminal 100 with information related to the metadata corresponding to the image. The configuration according to this embodiment will be described in detail with reference to FIGS. 6 to 8. FIG.

3 is a diagram for explaining a process of extracting words corresponding to contents according to an embodiment of the present invention. As shown, it can be understood that the same image 10 was used in a plurality of dialog windows (dialog window A and dialog window B), and that several words were used in the preceding and following sentences based on the image.

In the dialog window A, words such as "puppy", "cute", "cute" and "martine" are extracted. In the dialog window B, "dog", "quilt", "cute" The word was extracted.

For the sake of explanation, we have set the word "cute" as a, the word "puppy" as b, the word "futon" as c, and the word "Martinez" as d. Although four words are shown in the drawing, the number of extracted words can be changed and is not limited to the illustrated example.

In Dialog A and Dialog B, the previous sentence and the words used in the following two sentences are extracted based on the time the image was used, but this can be changed according to the setting. For example, you can extract sentences that were used in the previous sentence and the next sentence based on when the image was used, and extract words that were used in two or three sentences based on when the image was used It is possible.

Alternatively, words used in a sentence used within a predetermined time based on the point in time when the image is used may be extracted. For example, it is possible to extract a word used in a sentence entered in a dialog box within one minute based on the time when a specific image is used.

In addition, a method of extracting the word from one or more sentences inputted within a predetermined positional range before or after the publication position of the content may be used.

Furthermore, a method may be used in which a context is extracted from inputted sentences before or after the publication of the content, and a word is extracted from one or more sentences inputted within a set range of paragraphs before or after the content is published.

4 is a diagram for explaining a frequency of use of words that can serve as a reference in selecting a content-corresponding key word according to an embodiment of the present invention. The extracted word in FIG. 3 may have a variation depending on the personality of the person according to the character of the dialogue. Therefore, it is possible to determine the more accurate keyword through the process of selecting the keyword based on the word extracted most commonly .

As shown in FIG. 4, words used for one image are extracted from a plurality of dialog windows, and the frequency of use of the extracted words is calculated. Specifically, the words' puppy ',' cute 'and' martin 'were extracted from the dialog window A of FIG. 3, and' puppy ',' quilt ',' cute ',' The words 'heart' were extracted.

In Figure 4, the word 'dog' was used most often, and the word 'cute' was used next. As the number of dialog windows using the same image increases, the frequency of use of the extracted words can be more accurate. For example, when the frequency of use of each word is summed up, As shown in FIG.

Keywords can be changed in the process of extracting the top few words in the order of the highest frequency of use as keywords of the image. That is, the ranking in which the frequencies of use of the words extracted for the same image are summed can be changed with time.

By extracting the words used in the plurality of dialog windows as described above, the words that are generally related to the image used when the image is used in the dialog window are extracted and the metadata is generated using the extracted words, Extraction and information can be provided.

5 is a diagram for explaining a process of generating content-corresponding metadata according to an embodiment of the present invention.

For example, if the image is shared in one or more dialog windows in step S110, a word used in the sentence is extracted within a predetermined range based on the sharing point. The process of extracting a word may be performed by searching a word list of a database in which the words included in the sentence are recorded in the keyword extracting unit or interworking with each other, and checking whether they are matched.

Next, the frequency of use is calculated (e.g., summed) for each word extracted from the one or more dialog windows (S120), and the top n words, for example, in descending order of frequency of use (S130).

Next, the keyword is tagged to an image to generate metadata (S140).

6 to 9 are views for explaining a method of providing an advertisement corresponding to contents according to an embodiment of the present invention.

When the image storing the metadata is used in the same dialog or other dialog window through the process of FIG. 5, if the image is indicated by an appropriate instruction means such as a click or a tap, A detailed view layer or a menu related to the set image can be displayed.

However, the present invention is not limited thereto. For example, if the image is stored in the user terminal 100, the predetermined information may be provided to the user terminal 100, Even if the image is not posted in the dialog box, it is also possible to provide related information by indicating the stored image.

The detailed view layer associated with an image may include menus such as "save", "share", "delete", "get recommendations" of the image. Here, when the 'receive recommendation' menu 30 is selected, the keyword of the corresponding image stored in the meta data is displayed on the screen, and the user selects a specific keyword, which is related to the presented plurality of keywords, You may.

For example, if the recommendation receiving menu 30 is selected in FIG. 6, the keyword selection menu 40 of 'jeans', 'male bottom', 'shoes' and 'top' And when the user selects a specific keyword, the advertisement information related to the selected keyword may be provided. Here, the keywords appearing in the keyword selection menu 40 are the keywords extracted by the process of FIG. 5 for the corresponding image.

8, when the user selects a specific keyword in the keyword selection menu 40, the similar image menu 51, the related goods menu 52, and the related product menu 50 are displayed as the advertisement information menu 50 related to the selected image, An associated site menu 53 may be provided. Advertising information may be provided for each of the keyword selection menus 40 of FIG. Therefore, for example, when 'jeans' is selected in the keyword selection menu 40, the advertisement information menu 50 of FIG. 8 includes a similar image menu 51 related to 'jeans', a related goods menu 52, A menu 51 related to 'men's bottom', a menu 52 related to the menus 52, and a related menus 52 are provided in the advertisement information menu 50 of FIG. 8, And an associated site menu 53 may be provided.

For example, if a specific menu is selected from the advertisement information menu 50 of FIG. 8, similar images, related products, and related sites may be provided as shown in FIG.

In this case, a plurality of images may be provided. If a specific image is selected, the similar image is provided to the recommendation receiving menu 30 as in FIG. 6, Or may be linked directly to a page that sells the products displayed in the selected image.

The related product is linked to the page that sells the product displayed in the image, so that the user can purchase the product by setting the necessary option.

The related site provides an access route to one or more Internet sites that sell products displayed in an image or similar related products, and can receive advertisement information by selecting a desired site.

When the information providing server 200 purchases an object through the provided advertisement, the information providing server 200 may accumulate a predetermined point on the corresponding user terminal 100.

In addition, when the first user terminal 110 stores an image and uploads the image to another chat room, if the user terminal 100 in another chat room indicates the image, a recommendation receiving menu for the corresponding information is displayed .

10 is a view for explaining a method of providing content corresponding information according to another embodiment of the present invention.
