[ The control unit 120 may access the data stored in the memory 140 and use the data or store the new data in the memory 140. [ Also, the control unit 120 may execute a program installed in the memory 140. [ Referring to FIG. 1, a memory 140 may be provided with a program for performing a meta information setting method.

According to one embodiment, when a search request for an image corresponding to a search keyword obtained from a user is received through the input / output unit 110, the control unit 120 executes a program stored in the memory 140 to set a meta information setting method .

First, the input / output unit 110 of the meta-information setting apparatus 10 can obtain a search keyword from a user and output a section of the video in which a keyword corresponding to the search keyword is set as meta information.

That is, the input / output unit 110 can provide the user with a partial image of the image in which the keyword corresponding to the search keyword obtained from the user is set as the meta information among the images in which the meta information is set by the control unit 120, which will be described later.

Then, the input / output unit 110 may obtain feedback on the partial image of the image provided corresponding to the search keyword from the user.

According to the embodiment, the input / output unit 110 may provide a pop-up window for confirming whether the partial image provided to the user corresponds to the search keyword, and may include a user input for acquiring user input in the pop-up window have.

For example, the input / output unit 110 may select one of "upper, middle, and lower" as satisfaction with whether the partial image corresponds to the search keyword from the user.

The input / output unit 110 may provide the control unit 120 feedback obtained from the user.

On the other hand, the meta-information setting apparatus 10 may include a control unit 120. [ The control unit 120 may set meta information for a partial image which is one section of the image satisfying a preset condition.

For this purpose, the control unit 120 may collect, as popular keywords, keywords corresponding to predetermined conditions among the keywords that the at least one user searches through the Internet.

For example, the control unit 120 may collect keyword popular keyword rankings for which the search ranking is within the 10th rank for one week in the Internet portal service, or one day among the search keywords input by the user searching for the image, You can collect keywords that are viewed more than 100 times as popular keywords.

The control unit 120 can search for and acquire an image corresponding to the popular keyword based on the collected popular keyword.

For example, the control unit 120 can select an upper certain number of images among the images retrieved through the search service based on the collected popular keywords, and acquire the images in streaming based on the URL addresses of the selected images .

According to one embodiment, when the caption is included in the image, the control unit 120 can set meta information of the image based on the caption.

First, the control unit 120 can extract at least one noun included in the caption by analyzing captions of an image.

For example, the control unit 120 can identify the time information of the caption of the image starting from the image of the caption, and extract only the noun of the words included in the caption. At this time, extracted nouns can be converted into noun sets without duplicates.

The control unit 120 may analyze the intervals identified in the subtitles for each noun extracted from the subtitles and set a section in which specific nouns are frequently displayed.

For example, if the time interval between the time when the first noun is identified in the caption exceeds one minute, which is the preset time, the control unit 120 determines that the first noun is identified, Can be set.

If the interval between the first nouns is consecutively shorter than the predetermined time, the controller 120 determines whether the first noun is consecutive from the last recognized noun to the ending time Can be set.

Then, the control unit 120 searches for a partial image of an image corresponding to the section of the set subtitle, and sets the meta information of the searched partial image as a noun.

According to another embodiment, the control unit 120 may set the meta information of the image based on the retrieved image based on the popular keyword.

First, the control unit 120 can search for and acquire an image based on popular keywords. At this time, the larger the number of images selected by the control unit 120, the more meta information corresponding to the popular keyword can be obtained, while the smaller the number of images to select, the higher the accuracy of the search.

The control unit 120 may calculate the similarity between each of the frames constituting the retrieved image and the image, and may set the interval of the image including the frame satisfying the predetermined condition for each image.

 For example, the control unit 120 may decode a compressed image, extract it as a set of frames, extract the objects included in each frame, and sequentially calculate similarities with images corresponding to popular keywords using an object matching algorithm have. The control unit 120 can select a frame having a similarity degree to the image of the image frame equal to or greater than a predetermined value, and if the selected images are continuously present, the playback time of the first frame selected is the start time, You can set the interval by time

Then, the controller 120 may set the meta information of the image as meta information of the partial image of the image corresponding to the set interval. For example, the control unit 120 may set a title of an image obtained by comparing the degree of similarity with meta information of a partial image corresponding to a predetermined section.

At this time, according to the embodiment, the control unit 120 may compare the set meta information using each of the caption and the image with respect to the partial image, and determine the optimal keyword to be set as the meta information.

For example, the control unit 120 obtains a similar keyword associated with the meta information of the image, and obtains a second partial image having the meta information set using the image among the first partial images set with meta information using the caption, And the meta information of the image and the similar keyword may be set as the meta information of the second partial image based on the meta information of the first partial image.

Thereafter, the control unit 120 may search for an image based on a search keyword obtained from the user through the input / output unit 110, and may provide a partial image in which meta information corresponding to the search keyword is set.

In this case, if the searched partial image exceeds a preset time, the controller 120 may provide the searched partial image. However, if the searched partial image is less than a preset time, May provide a portion of the image at random.

The controller 120 may adjust the duration of the partial image when the feedback of the user regarding the duration of the provided image is obtained.

For example, the control unit 120 does not adjust the interval of the partial image when the feedback is 'up' but can increase the interval between the start time and the end time when the feedback is 'middle' or 'low' This is expressed as the following equation.

Start time = start time X (1-a), end time = end time X (1 + a)

(a: feedback parameter)

Meanwhile, the memory unit 140 may store the start and end points of the set interval as keywords, which are meta information of the corresponding interval.

 That is, the memory unit 140 may store meta information set by the control unit 120 on the image and information on a section of the partial image corresponding to each meta information.

2 to 3 are flowcharts for explaining a method of setting meta information according to an embodiment.

The method for setting meta information according to the embodiment shown in FIGS. 2 to 3 includes the steps of the meta-information setting apparatus 10 shown in FIG. Accordingly, even though omitted from the following description, the description of the meta information setting apparatus 10 shown in FIG. 1 can be applied to the meta information setting method according to the embodiment shown in FIGS.

First, the meta-information setting apparatus 10 can acquire an image corresponding to a popular keyword, which is a set of keywords corresponding to predetermined conditions (S2001).

For example, the meta-information setting device 10 can acquire a word within the 10th search rank in the portal site as a popular keyword, and retrieve an image corresponding to the acquired popular keyword to acquire the retrieved image.

Then, the meta-information setting apparatus 10 can identify whether the caption is included in the acquired image (S2002).

In a case where a caption is included in an image according to one embodiment, the meta-information setting apparatus 10 may extract nouns included in captions by analyzing the captions (S2003).

For example, the meta-information setting apparatus 10 can classify subtitles into morpheme units to identify and extract nouns, and extract nouns in the subtitles so as not to overlap with the extracted nouns.

Then, the meta-information setting apparatus 10 can search for a partial image of an image corresponding to a section in which the extraction frequency of nouns in the caption satisfies predetermined conditions (S2004).

For example, the meta-information setting apparatus 10 may set a predetermined time range as a section based on a point in time when a noun is identified when the time interval between the time when the noun is identified in the caption exceeds a preset time, The partial image of the image corresponding to the section of the subtitle can be searched.

The meta information setting apparatus 10 may set the extracted noun as meta information for the partial image searched in step S2004 (S2005).

On the other hand, if there is no caption in the image obtained in step S2002, the meta-information setting apparatus 10 can acquire an image associated with the popular keyword (S2006).

For example, the meta-information setting apparatus 10 can acquire at least one image retrieved from a search site using popular keywords.

Then, the meta-information setting apparatus 10 can calculate the similarity with the image obtained in step S2006 for each frame constituting the image obtained in step S2001, and includes a frame whose similarity with the image satisfies predetermined conditions (S2007), and the meta information of the image can be set as the meta information of the partial image of the searched image (S2008).

Then, the meta-information setting apparatus 10 can acquire the search keyword from the user (S2009), and search the partial image based on the acquired search keyword to provide the searched partial image (S2010).

The meta-information setting apparatus 10 can acquire feedback on the partial image provided from the user (S2011). The section of the partial image can be adjusted based on the obtained feedback (S2012).

FIG. 3 is a flowchart illustrating a method of setting meta information of an image using both the caption of the image and the searched image in the popular keyword according to an embodiment of the present invention. However, for the sake of convenience of description, the description overlapping with the description in FIG. 2 will be omitted.

Referring to FIG. 3, the meta-information setting apparatus 10 can acquire an image based on a popular keyword (S3001).

The meta-information setting apparatus 10 can search an image based on popular keywords and acquire a predetermined number of images of the searched image (S3002).

Thereafter, the meta-information setting apparatus 10 can calculate the similarity with each frame constituting the image obtained in the step S3001 based on the image obtained in the step S3002, and the calculated similarity is determined as a frame satisfying the predetermined condition The meta information of the partial image to be constructed can be set (S3003).

That is, the meta information setting apparatus 10 can set the meta information of the image as the meta information of the partial image set in step S3003. For example, the meta-information setting apparatus 10 may set the 'vision', which is the title of the 'current resolution' image, as the meta information of the partial image.

At this time, the meta-information setting apparatus 10 can collect similar keywords, which are keywords related to the meta information of the image.

For example, the meta-information setting apparatus 10 may collect keywords such as 'weather', 'fine weather', and 'starfish', which are keywords related to 'weather forecast'.

Then, the meta-information setting apparatus 10 can extract the nouns from the subtitles included in the image obtained in the step S3001 without overlapping (S3004), calculate the frequency of the extracted nouns within the subtitles, A partial image corresponding to a satisfactory section can be searched (S3005).

In step S3005, the meta-information setting apparatus 10 may search for a partial image overlapped with the partial image found in step S3003 among the partial images set for each noun in step S3005.

If there is an overlapping partial image, the meta-information setting apparatus 10 weights the meta information of the partial image set in step S3003 and the similar keyword based on the meta information of the partial image set in step S3005, Information can be determined (S3007).

For example, if the meta information of the first partial image set using the caption is 'weather', the meta-information setting apparatus 10 sets meta information of the second partial image overlapping with the first partial image, Weights can be assigned to 'weather', 'clear' and 'weather' of the similar keywords of 'weather forecast', and the meta information of the second partial image can be set to 'weather'.

Thereafter, the meta-information setting apparatus 10 can acquire the search keyword from the user (S3008), and can search the partial image based on the obtained search keyword and provide the searched partial image (S3009).

The meta-information setting apparatus 10 can acquire feedback on the partial image provided from the user (S3010). The section of the partial image can be adjusted based on the obtained feedback (S3011).
