Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 1 to 12.

1 is a block diagram of an apparatus for providing content information according to an embodiment of the present invention.

Referring to FIG. 1, the content information providing apparatus 100 according to an embodiment of the present invention may provide (recommend) content information of other contents similar to (or related to) content selected and watched by the user to the user. have.

To this end, the content information providing apparatus 100 performs a batch operation of classifying contents into a vector space based on relevance. Here, the batch operation is a batch operation of a series of jobs in a unit of work periodically, the batch operation in the present invention manages the vector information on the vector space of the content using the learned network management information It may include a series of actions to generate as. In the present invention, the batch operation is a Korean expression for the batch, and even if the batch is not written together, the batch operation may mean a batch operation.

The learned network may generate management information of contents based on the learned algorithm, and the learned algorithm may be defined as an algorithm for generating related contents to have similar management information values. For example, depending on the result of the arranging operation, similar contents may have management information located adjacent to the vector space. Here, the term "object" means that the contents are similar or similar to each other in terms of content, subject, material, appearance, category, summary, or user's viewing history pattern. It may include the order of viewing, the viewing period of the content, and the like. For example, content with similar viewing frequency may be related contents, contents sequentially viewed according to the viewing order of contents may be relevant contents, and contents simultaneously viewed by users for a certain period may be relevant. This may be the content.

The content information providing apparatus 100 may generate management information about contents stored or registered in the content information providing apparatus 100 by performing a batch operation at a predetermined cycle.

The content information providing apparatus 100 may calculate similarity between contents by using management information of each generated content, and recommend similar contents based on the calculated similarity. In this case, the relevance means similarity of the contents, and the similarity means the degree of relevance of the contents. That is, the content information providing apparatus 100 generates vector information (management information) on a vector space of each content based on a relevance-based learning algorithm. In addition, the content information providing apparatus 100 classifies content having high similarity as similar content based on vector information (management information) of each content using a similarity algorithm. Here, 'similar content' may mean the same or similar content in content, theme, location, appearance, category, summary, and viewing history pattern of users.

The content information providing apparatus 100 is connected to the user terminal 200 through wired / wireless communication. When a keyword is received from the user terminal 200, the content information providing apparatus 100 extracts contents corresponding to the received keyword and extracts content list information of the extracted contents. It may be generated and provided to the user terminal 200. In addition, when an arbitrary content is selected from the content list, the content information providing apparatus 100 may provide information of content similar to the selected content based on management information of the selected content (eg, location information on a vector space). By providing to the user, the user can continue to watch the similar content using the provided similar content information. For example, the content list information may mean a list of contents searched and extracted by a keyword.

In more detail, the content information providing apparatus 100 according to an exemplary embodiment of the present invention may include the content management unit 110, the content search unit 120, the content information generation unit 130, and the content information providing unit 140. It may include.

The content manager 110 classifies the contents into a vector space through a relevance-based algorithm of the contents and performs a layout operation of generating location information, that is, vector information (management information), in the vector space. That is, the content manager 110 may generate vector information on a vector space of contents as management information by using the learned network. For example, the learned network may generate management information of contents based on the learned algorithm, and the learned algorithm may be defined as an algorithm for generating relevant contents to have similar management information values. The learned network generates vector information of similar contents with similar values according to a predetermined criterion (relevance), and the content manager 110 may generate vector information (management information) using various relevance measurement techniques.

The content search unit 120 extracts contents corresponding to the received keyword and generates content list information of the extracted contents. For example, when "skin management" is received as a keyword, contents related to "skin management" may be extracted to generate a content list. For example, the content retrieval unit 120 may generate a content list based on a time sequence in which the content is registered in the content information providing apparatus 100.

The content information generation unit 130 generates similar content information of the selected content based on the management information of the content selected from the content list information. That is, the content information generation unit 130 may calculate the similarity of the contents in the vector space, classify the contents by the vector group based on the similarity, and generate the contents in the vector group including the selected content as similar content information. . In addition, the content information generation unit 130 may generate, as similar content information of the selected content, information of contents having a similarity or more than a reference similarity among the calculated similarities. Here, as the method for calculating the similarity, various methods such as a distance-based Euclidean similarity algorithm and an angle-based cosine similarity algorithm may be applied according to the similarity calculation algorithm. As a method of calculating the similarity, the content information generation unit 130 determines that the contents that are close to the selected content on the vector space are similar in the similarity to the selected content, and are located within a predetermined distance (close distance) from the selected contents. Similar content information may be generated using the contents. The distance-based similarity calculation between the contents of the present invention is only one method of calculating the similarity, but the present invention is not limited thereto, and the present invention can calculate the similarity between contents using various similarity algorithms.

In addition, when there is no management information on the selected content, the content information generation unit 130 may generate similar content information using content viewing history information or content list information of the user. The operation of the content information generator 130 will be described in more detail below.

The content information providing unit 140 provides the content list information and the similar content information generated by the content information generating unit 130 to the user terminal 200. To this end, the content information providing unit 140 may perform wired or wireless communication, and may include various communication units for performing wired and wireless communication.

2 is an exemplary diagram representing an n-dimensional vector space of a content information providing apparatus according to an embodiment of the present invention as a two-dimensional vector space.

2, the content may have management information according to a batch operation performed by the content manager 110 of the content information providing apparatus 100. The management information may mean location information on the vector space of the content. At this time, similar contents are located close to the vector space as shown in FIG. 2. Contents having high similarity to the selected content may be formed of the same vector group 10, 11, 12.

The content information generating unit 130 of the content information providing apparatus 100 generates similar content information based on the management information. The vector group including content having high similarity to the selected content, that is, the selected content as shown in FIG. 2. Similar content information may be generated using the contents in (10, 11, 12).

3 shows a result of representing an n-dimensional vector space of a content information providing apparatus according to an embodiment of the present invention as a two-dimensional vector space.

Referring to FIG. 3, a case in which content is an image is illustrated. For example, the vector group 13 is an example in which monkey images are gathered to form a vector group, and the vector group 14 is an example in which owl images are gathered together to form a vector group. In this case, the content manager 110 may generate management information of the contents by performing a batch operation including new contents newly registered or uploaded to the content information providing apparatus 100 at predetermined intervals.

4 is a view for explaining management information generation of contents by a batch operation according to an embodiment of the present invention.

Referring to FIG. 4, for example, management information of contents 1, 2, and 3 is generated according to the arrangement operation of the content management unit 110, and is newly updated before the execution of the next arrangement operation of the content management unit 110 is completed. In the generated (ie, newly uploaded or registered) contents 4, 5, and 6, the arrangement operation of the content management unit 110 may not be performed, and thus management information may not exist. Subsequently, when the period of the arrangement operation of the content management unit 110 arrives and the arrangement operation of the content management unit 110 is performed, management information of the contents 4, 5, and 6 may be generated.

In addition, in the case of the contents 7 and 8, the management information is generated before the content management unit 110 is disposed, and there is no management information. When the content management unit 110 is arranged, the management information is generated.

As such, since the content management unit 110 performs a batch operation according to a preset cycle, among the contents uploaded or registered in the content information providing apparatus 100, there may be content that does not have management information according to a time point at which it is uploaded or registered. have.

FIG. 5 is an exemplary view of recommendation of similar content for content in which a deployment operation is completed and management information exists according to an embodiment of the present invention, and FIG. 6 is management information since the deployment operation is not completed according to an embodiment of the present invention. Is an example of recommendation of similar content for content that does not exist.

First, referring to FIG. 5, "skin management" is input as a keyword in the user terminal 200 and transferred to the content information providing apparatus 100. Accordingly, one of the contents list generated by the content searching unit 120 is selected. When the content is viewed, the similar content information classified into similar content as the viewed content based on the management information of the viewed content may be provided to the user terminal 200.

For example, the viewed content is registered in the content information providing apparatus 100 11 months ago and may have management information as the execution of the batch operation is completed. The content information generation unit 130 provides similar content information generated based on the management information of the content to the user terminal 200. Similar content information may provide at least one or more, and as shown in FIG. The contents may be provided as the similar content list 16.

Referring to FIG. 6, when the selected content is content registered in the content information providing apparatus 100 25 minutes ago, it may be displayed as a new video 18. Content newly registered in the content information providing apparatus 100 may not have management information generated because the arrangement operation by the content management unit 110 is not performed. Therefore, since the content information generation unit 130 is difficult to accurately extract the content similar to the selected content, the content information of the similar content list 19 may include content information.

As such, when the content management unit 110 does not complete the arrangement operation, the similarity accuracy of the similar content is lowered, so that the content information generation unit 130 does not select the content in the content list generated corresponding to the keyword. Similar content information may be generated based on management information of other content in which management information exists. For example, the content viewed as shown in FIG. 6 is a skin care (spa) related content, and the similar content may include a startup school manual which is not related to skin care (spa).

7A illustrates an example of content in which a batch operation is completed and management information exists and batch of new content in which no management information exists because the batch operation is not completed according to an embodiment of the present invention. FIG. 7B is a view illustrating an embodiment in which similar content information is recommended using a keyword search-based content list in the case of the content in which the batch operation is not completed in FIG. 7A, and FIG. 7C is a diagram in which the batch operation of FIG. In the case of content, it is a diagram for explaining an example of recommending similar content information based on content viewing history information.

Referring to FIG. 7A, content A, B, and C are in a state in which a management operation is performed, and content D, E, and F are registered in the content information providing apparatus 100 after the placement operation. As the batch operation is not completed yet, management information may not be generated.

When the content F in which the management information does not exist is selected and viewed, since the content F does not have the management information, as shown in FIG. 7B, the content information providing apparatus 100 receives a message received from the user terminal 200. Skin similarity information of one of the contents (A, B) of the completion of the batch operation among the contents (D, E, A, B) included in the contents list generated based on the “skin care” keyword The content information may be provided to the user terminal 200.

In this case, the content information generation unit 130 may use the management history information for each content to distinguish the contents A and B having completed the batch operation among the contents D, E, A, and B included in the contents list. . In addition, the content information generation unit 130 does not use the management history information, the registration point of time among the contents (D, E, A, B) included in the content list before any point of time (any point in consideration of the placement period) Similar content information may be selected to generate similar content information of the content F using the similar content information of the corresponding content.

For example, when the execution period of the batch operation is one month, the content information providing apparatus 100 selects the content registered in the content information providing apparatus 100 one month before the content list, and thus the similarity of the content registered one month ago. The content information may be provided to the user terminal 200 as similar content information of the content F. FIG.

In addition, as another method for providing the similar content information to the user terminal 200 when the management information of the viewed content is not generated, the content information generating unit 130 uses the content viewing history information to provide the similar content information. Can be generated. That is, the content information generation unit 130 determines whether there is content in which the management information exists by the completion of the batch operation among the content viewing history information of the user, and when the content in which the batch operation is completed is included in the content viewing history information, the batch operation is performed. Similar content information may be generated using the completed content.

Referring to FIG. 7C, the content viewing history information includes contents (E, A, B, and C) that have already been viewed, and contents (E, A, B, and C) that have already been viewed may be arranged in chronological order. have. Here, the content E may be in a state in which the batch operation is not completed, and the remaining content A, B, and C may be in a state in which the management information is generated because the batch operation is completed. In this case, the content information providing apparatus 100 is configured so that the content E most recently registered in the content information providing apparatus 100 is positioned at the top, and the content registered in the content information providing apparatus 100 in the past ( Contents may be displayed such that C) is located at the bottom.

When the content F in which the batch operation is not completed is selected and viewed, since the management information of the viewed content F does not exist, the content information providing apparatus 100 may not perform the batch operation among the content viewing history information as shown in FIG. 7C. By selecting one of the completed contents A, B, and C, similar content information may be recommended to the user terminal 200 based on management information of the selected content.

In addition, the content information generation unit 130 may use the management history information for each content to distinguish among the contents A, B of the contents E, A, B, and C included in the content list, in which the arrangement operation is completed. . In addition, the content information generating unit 130 does not use the management history information, the registration point of time among the contents (E, A, B, C) included in the content list before any point (any point in consideration of the placement period) By selecting the content of the content, similar content information of the corresponding content may be used. For example, when the execution period of the batch operation is one month, the content information providing apparatus 100 selects the content A registered in the content information providing apparatus 100 one month before the content list and is registered one month ago. Similar content information of the content A may be provided to the user terminal 200 as similar content of the content F. FIG.

8 is a block diagram of a content information providing apparatus according to another embodiment of the present invention.

Referring to FIG. 8, the content information providing apparatus 300 according to an embodiment of the present invention may include a storage unit 310, an authentication unit 320, a control unit 330, a content management unit 340, and a content search unit 350. , The content information generator 370, and the content information provider 380.

The storage unit 310 stores content, management history information for each content, content viewing history information for each user, and user information. In this case, the management history information for each content includes management information by a batch operation, and the content viewing history information for each user is viewed by the user for a predetermined period (which may be a period predetermined by the user).

It may include information of contents. The user information may include user ID, user name information, and the like. The storage unit 310 may include various types of volatile or nonvolatile storage media. For example, the storage 310 may include a read only memory (ROM) and a random access memory (RAM).

The authentication unit 320 performs user authentication when a user logs in a request by using information of a user (member) subscribed to a content recommendation service. Accordingly, content viewing history information viewed in a state where user authentication is successfully logged in may be stored in the storage unit 310.

The controller 330 controls the overall operation of each component. The controller 330 may be a central processing unit (CPU) or a semiconductor device that executes processing for instructions stored in a memory and / or storage.

The content manager 350, the content searcher 360, the content information generator 370, and the content information provider 380 may be the content manager 110, the content searcher 120, or the content information generator of FIG. 1. 130, since the operation is the same as the content information providing unit 140, a detailed description thereof will be omitted.

As described above, the present invention performs a batch operation of periodically classifying contents registered in the content information providing apparatus 100 in a vector space based on relevance, and based on the similarity of management information obtained through the batch operation. Highly similar content information can be provided. In the case of content registered in the content information providing apparatus 100 between a time when a previous batch operation is performed and a time when the next batch operation is performed, there is no management information of the content because no batch operation is performed, and thus the accuracy of recommendation of similar contents is recommended. In order to solve the problem of lowering, the present invention can increase the accuracy of recommendation of similar content by providing similar content information based on the content list or content viewing history information acquired through keyword search.

Hereinafter, a method of arranging registered content according to an embodiment of the present invention will be described with reference to FIG. 9.

9 is a flowchart illustrating a method of performing a batch operation on registered content according to an embodiment of the present invention.

Referring to FIG. 9, when the content information providing apparatus 100 of the present invention is generated and registered (S110), vector information (management information) of contents is provided by a learning network based on the relevance of the contents according to a predetermined period. ) Is generated (S120). In other words, contents are classified based on relevance and have vector information.

 Thereafter, the content information providing apparatus 100 stores the generated management information (S130).

The content information providing apparatus 100 may generate generated and registered contents at predetermined intervals through the learned network to generate management information of the contents, and relevant contents may have similar management information values. .

Thereafter, the content information providing apparatus 100 may provide similar content information having high similarity in the vector group of the selected content as recommended content (similar content information) based on management information (vector information) of the content selected by the user. .

10 is a flowchart illustrating a method of providing content information according to an embodiment of the present invention.

Referring to FIG. 10, when a keyword is received from the user terminal 200, the content information providing apparatus 100 extracts contents corresponding to the keyword (S210). Next, the content information providing apparatus 100 generates a content list using the extracted contents and provides the generated content list to the user terminal 200 (S220). Here, the content list may be generated based on a time sequence in which the content is registered in the content information providing apparatus 100. In this case, in order to extract the keyword-based content, the content information providing apparatus 100 previously stores keyword information for objectively describing the corresponding content, such as a subject, material, appearance, category, summary, etc. for each content, and the user terminal 200. The content list information is generated by extracting the content including the keyword received from the " In this case, the content list extraction may use a conventional technique.

 For example, as shown in FIG. 5, when the keyword is “skin management”, contents including the keyword “skin” or “skin management” may be provided in the order of time registered in the content information providing apparatus 100.

Thereafter, when one content of the content list is selected and reproduced in the user terminal 200 (S230), the content information providing apparatus 100 determines whether the management information of the reproduced content exists (S240). In this case, the content information providing apparatus 100 may determine whether the management information of the reproduced content exists using the management history information.

Thereafter, if the management information of the selected content exists, the content information providing apparatus 100 recommends similar content information in the corresponding vector group based on the management information of the selected content (S250). Referring to FIG. 2, a plurality of vector groups 10, 11, 12... Are already generated through a batch operation, and the content information providing apparatus 100 may be configured in a vector group including selected content among a plurality of vector groups. Similar content information is provided to the user terminal 200.

On the other hand, if the management information of the selected content is not present, the content information providing apparatus 100 is the content of the content that is not selected by the user in the content list, or the content of the content before any point from the current time Similar content information is recommended to the user terminal 200 based on the management information (S260).

In this case, the content information providing apparatus 100 may know the content on which the deployment operation is completed, based on the management history information for each content. In addition, the content information providing apparatus 100 may determine the content before a certain point in time (before the placement period) from the current time point as the content in which the management information exists based on the placement period. For example, if the batch period is one week, the content generated at the time of one week ago is likely to exist because the batch operation has already been completed, the content information providing apparatus 100 is one week from the current time Similar content information of content generated one week ago using management information of content generated at a previous time point may be recommended to the user terminal 200 as similar content information of content selected and reproduced in step S230.

As described above, according to the exemplary embodiment of the present invention, when content management information does not exist, similar content information may be provided based on a keyword-based content list.

Hereinafter, a method of providing similar content information according to another embodiment of the present invention will be described with reference to FIG. 11. 11 is a flowchart illustrating a method of providing similar content information according to another embodiment of the present invention.

Referring to FIG. 11, when a keyword is received from the user terminal 200, the content information providing apparatus 100 extracts contents corresponding to the received keyword (S310), and generates content list information using the extracted contents. Provided to the user terminal 200 (S320).

Thereafter, when one content of the content list is selected and reproduced in the user terminal 200 (S330), the content information providing apparatus 100 determines whether there is management information of the reproduced content (S340). In this case, the content information providing apparatus 100 may determine whether there is management information of the reproduced content using the management history information of the content.

Thereafter, if the management information of the selected content exists, the content information providing apparatus 100 provides similar content information in the corresponding vector group to the user terminal 200 based on the management information of the selected content (S350).

If the management information of the selected content does not exist, the content information providing apparatus 100 inquires the content viewing history information (S360). The content information providing apparatus 100 determines whether there is content in which the management information exists among contents included in the content viewing history information (S370), and among the contents included in the content viewing history information, content in which the management information exists is present. If present, similar content information is recommended based on management information of the corresponding content (S380). That is, similar content information of content having management information in the content viewing history information may be recommended as similar content information of the content selected and reproduced in step S330. This may be implemented assuming that the user has previously watched content with a similar keyword.

Meanwhile, when there is no content with management information in the content viewing history information, as shown in FIG. 10, the content information providing apparatus 100 may use the similar content based on the management information of the unselected content in the keyword-based content list. Information may be recommended (S390). In other words, the content information providing apparatus 100 is based on the similar content information based on the management information of the content of the content list that is not selected by the user in the content list is completed and the management information is generated or the content before a certain point in time from the current time point Do a recommendation.

As described above, the present invention provides a content providing service that performs a batch operation at a predetermined period and generates management information. The management information of newly registered contents is not generated between the current batch operation until the next batch operation is performed. In order to solve the problem of low accuracy of recommendation of similar content, by recommending to the similar content information user terminal 200 using the content list searched by the keyword and the content viewing history information, the accuracy of recommendation of similar content may be improved.
