1 is a block diagram of an advertisement system according to an embodiment of the present invention.

As shown in FIG. 1, the advertisement system according to an embodiment of the present invention provides an advertisement consumer terminal 20 that requests and accepts advertisements and consumes advertisements, and provides advertisements previously prepared by advertisers to advertisement consumers. Includes an advertisement supply server 32, wherein the advertisement supply server 32 can provide advertisements so that advertisements are displayed through an advertisement mediator included in contents provided at the request of the advertisement consumer terminal 20. have.

Here, the advertisement may have a form such as graphic advertisements such as so-called banner advertisements, text-only advertisements, image advertisements, audio advertisements, video advertisements, or a combination of one or more of them. .

The content supply server 31 may provide content in response to a content request from the advertisement consumer terminal 20, and at this time, the advertisement supply server 32 provides an advertisement according to an advertisement request from the content supply server 31. Thus, the content supply server 31 may provide the advertisement-inserted content to the advertisement consumer terminal 20 through an advertisement intermediary.

In contrast, when the advertisement consumer terminal 20 makes a content request to the content supply server 31, the content supply server 31 sends an advertisement command embedded in the content along with the content to the advertisement consumer terminal 20. In response, the advertisement consumer terminal 20 may make an advertisement request to the advertisement supply server 32 according to the embedded advertisement command. Accordingly, the advertisement supply server 32 may deliver an advertisement in response to the advertisement request, and the advertisement consumer terminal 20 may allow the advertisement to be displayed through the advertisement mediator of the content.

Here, the content is content outputted through the advertisement consumer terminal 20, and for example, may have the form of articles, discussion rooms, music, video, graphics, search results, web pages, etc. In may include an area in which an advertisement is displayed.

On the other hand, the advertisement system includes an advertisement intermediary server 100 that sets the advertisement supply server 32 to provide advertisements related to the contents or advertisements when the advertisement mediator of the contents provides advertisements to advertisement consumers. I can.

The advertisement supply server 32 provides advertisements previously prepared by advertisers to advertisement consumers, but may be set by an advertiser or the like to provide customized advertisements suitable for advertisement consumers or contents.

That is, as shown in FIG. 3, the advertiser sets a keyword indicating a predetermined topic or interest in the advertisement supply server 32 by using the advertiser terminal 10, or consumes advertisement among advertisement consumers. When setting an advertisement target to be a target (or target), the advertisement supply server 32 is an advertisement consumer terminal so that advertisements can be displayed to content matching the keyword and/or and/or advertisement consumers. You can provide an advertisement to (20).

In order to provide an advertisement to an advertisement target, the advertisement supply server 32 uses the log data collected from the advertisement consumer terminal 20, and the advertisement consumer terminal 20 corresponding to the advertisement target set by the advertiser. You can provide advertising on Here, the log data may be user information (age, gender, region, etc.) collected by the advertisement consumer terminal 20 itself or a user behavior history (terminal, application, or web browser usage history), and advertisements included in the content. Can be collected by intermediaries.

On the other hand, Figure 2 is a configuration diagram of an advertisement mediation server according to an embodiment of the present invention.

As shown in Figure 2, the advertisement mediation server 100 based on the interface server 140, which provides a platform for receiving seed keywords from the advertiser, and a plurality of keywords extracted by the analysis server 120, It may include a setting server 130 configured to set an advertisement supply server 32 with an expanded keyword by extending the seed keyword to those related to the seed keyword, and the advertisement supply server 32 is the expanded keyword By expanding the range of contents related to advertisements, advertisements prepared in advance for contents of the extended range can be provided to the advertisement consumer terminal 20.

At this time, in order to expand the seed keyword input from the advertiser, the advertisement intermediary server 100 includes a web crawler 110 that collects web pages on the Internet, and the information included in the web pages collected by the web crawler 110. It may further include an analysis server 120 for extracting at least one keyword.

As a result, the advertisement intermediary server 100 according to an embodiment of the present invention expands a keyword that an advertiser inputs to specify an object (eg, content) to expose an advertisement to the advertisement supply server 32 to provide an advertisement supply server. By setting (32), it is possible to efficiently expose advertisements when the advertisement supply server 32 displays advertisements on content.

As for the advertisement mediation server 100, the components shown in FIG. 2 are not essential, so it goes without saying that an advertisement mediation server having more or fewer components than that may be implemented.

Hereinafter, each component of the advertisement mediation server 100 will be described.

The web crawler 110 is a means for automatically collecting information or documents on the Internet (for example, a set of instructions). The web crawler 110 visits various websites and creates a copy of the data. You can automatically collect information or documents on your website.

In order for the web crawler 110 to crawl the web, a distributed crawling method that simultaneously performs crawling using several distributed computing resources, or by selecting a web page that fits the crawler's policy and selecting only the selected pages A selective crawling method for performing crawling may be used, but the specific method for crawling is not particularly limited in the present invention.

In this case, when the web crawler 110 crawls, it may be divided and stored according to the detailed classification criteria according to the type of website or web page. As an example, since the web crawler 110 can collect news pages, and most news pages are framed by title, content, author, and creation date, a batch program is used to determine the frame according to the detailed classification criteria. You can divide and store each of them.

The analysis server 120 may extract at least one keyword by analyzing the information or documents collected by the web crawler 110. Here, the keyword may consist of words or word pairs in the form of letters.

In order for the analysis server 120 to extract keywords from the information included in the web page, according to an embodiment, the information or documents included in the web page first analyze morphemes using Komoran, etc. After removing stop words such as or endings, leaving only words such as nouns, verbs and/or adjectives, calculate pagerank (or textrank) for the remaining words, and then use the Pointwise Mutual Information (PMI) index between words. Thus, by selecting a group of words or words, the words or word pairs can be finally extracted.

That is, the analysis server 120 may extract a plurality of keywords by analyzing information, etc. included in various web pages collected by the web crawler 110.

Setting server 130, based on a plurality of keywords (for example, words or word pairs) extracted by the analysis server 120, a schedule for a seed keyword input through the interface server 140 Those with a degree of correlation above the level can be selected, and the seed keyword can be expanded using the selected keyword.

Specifically, the setting server 130 interlocks with the analysis server 120, and the same/similar words as the seed keyword, words within a predetermined distance from the same/similar seed keywords, and the same/similar seed keywords appear simultaneously. The seed keyword can be extended by selecting words of a predetermined frequency or less or words of a combination thereof as correlated words.

Alternatively, the setting server 130 expands the seed keyword by selecting words with a degree of similarity higher than a certain level by applying the seed keyword to a word dictionary in which the similarity (or correlation) between words and words is stored. You may.

On the other hand, according to an embodiment of the present invention, the advertisement mediation server 100 may include a database (not shown) that pre-stores stopword words or word pairs, and expands the seed keyword using the database. The advertisement supply server 32 may be set by excluding the stopword words or word pairs from one word.

When the analysis server 120 expands the seed keyword, low-level profanity or abusive language that may degrade the value of the advertising brand may be included in the expanded keyword, regardless of the advertiser's intention, and exclude such words or word pairs. It is preferable to pre-store a stopword word or word pair for this in a database to exclude it when the setting server 130 sets the expanded keyword in the advertisement supply server 32.

Eventually, the setting server 130 expands the seed keyword input from the advertiser through the interface server 140, and sets the expanded keyword in the advertisement supply server 32, so that about 5 keywords input by the advertiser Even though it is only, by expanding to dozens of keywords related to this and setting it in the advertisement supply server 32, an advertisement that can expose an advertisement so that an advertisement prepared by the advertiser can be displayed even for content including keywords not set by the advertiser. You can expand the range of content related to.

Meanwhile, the interface server 140 may provide a platform for receiving various inputs from a user such as an advertiser or for outputting an analysis or processing result of the advertisement mediation server 100. As described above, the interface server 140 according to an embodiment of the present invention may receive the seed keyword from an advertiser.

The interface server 140 is implemented in the form of a web server, so that the advertiser accesses the interface server 140 using a web browser and inputs a seed keyword, thereby targeting the content for the advertisement prepared by the advertiser to be displayed. Can be selected.

In addition, the interface server 140 may receive an input for the above-described advertisement target from an advertiser, and set the input advertisement target in the advertisement supply server 32.

Meanwhile, the analysis server 120 according to an embodiment of the present invention may classify the expanded keywords by categories according to preset criteria.

For the information or documents collected by the web crawler 110, the person who created or edited the information or document can arbitrarily set a category, and the web crawler 110 collects and analyzes the category set by the author or editor. 120 can use it as it is.

However, since the categories set by the author or editor for the corresponding information or document are not consistent, the analysis server 120 according to an embodiment of the present invention is provided from information or documents collected by the web crawler 110. It is desirable to classify the extracted keywords collectively according to the preset category classification criteria.

That is, since the same news is classified into different categories for each media company, the analysis server 120 according to an embodiment of the present invention uses a Convolution Neural Network (CNN) algorithm and a Bidirectional Encoder Representations from Transformers (BERT) algorithm. Thus, categories can be classified based on the extracted values.

Eventually, the analysis server 120 classifies the expanded keyword into a preset category (eg, politics, society, economy, culture, entertainment, sports, etc.), and assigns the classified category as an attribute for the keyword. I can. Accordingly, when the setting server 130 sets the expanded keyword in the advertisement supply server 32, the advertisement supply server 32 includes any one of the expanded keywords by dividing and setting it according to a category that is an attribute of the keyword. Even if it is a content, if it is content that is not related to a category assigned to a corresponding keyword, an advertisement prepared by an advertiser may be prevented from being displayed on the corresponding content.

That is, it is preferable that the advertisement supply server 32 allows advertisements to be provided to content related to both the expanded keyword and the corresponding category.

As an example, the analysis server 120 expands the keywords input by the advertiser, and the expanded keywords are'stock','real estate', etc., so that a category of'finance' may be assigned to these extended keywords, and the setting server When 130 sets'stock','real estate', etc. as keywords extended to the advertisement supply server 32, it may be set only in the'finance' category among several categories. If the actual user of the advertisement consumer terminal 20 is 35 to 54 years old, but the child is watching a video in the'infant' category using the advertisement consumer terminal 20,'stock','real estate', etc. Even if it is related content, the advertisement can be prevented from being displayed.

To this end, as shown in FIG. 4, in order for the advertisement supply server 32 to provide and display content customized advertisements to the advertisement consumer terminal 20, the content supply server 31 provides the contents to the advertisement consumer terminal 20. When providing, the analysis server 120 may classify a category for a corresponding content in which an advertisement is displayed through an advertisement mediator included in the corresponding content, and determine whether to display an advertisement according to the classified category.

The advertisement intermediary server 100, specifically the analysis server 120, collects information (document or keyword, etc.) on the content through the content supply server 31, or through the advertisement mediator of the advertisement consumer terminal 20. Information about (document or keyword, etc.) can be collected, and the analysis server 120 extracts the keyword from the collected information, and then selects a preset category (eg, politics, society, economy, culture, etc.) Entertainment, sports, etc.).

When the advertisement supply server 32 provides an advertisement to content related to a keyword based on a preset keyword (including an expanded keyword), the category classified for the content by the advertisement brokering server 100 is the keyword ( If it does not correspond (same or similar) to the category for (including expanded keywords), the advertisement can be prevented from being displayed in the corresponding content.

Meanwhile, the analysis server 120 according to an embodiment of the present invention may calculate a sentiment index for content in which advertisements are displayed.

As shown in FIG. 5, when the content supply server 31 provides content to the advertisement consumer terminal 20, the analysis server 120 relates to the content in which advertisements are displayed through the advertisement mediator included in the content. The emotional index can be calculated, and whether or not to display an advertisement can be determined according to the calculated emotional index.

The advertisement intermediary server 100, specifically the analysis server 120, collects information (document or keyword, etc.) on the content through the content supply server 31, or through the advertisement mediator of the advertisement consumer terminal 20. Information (document or keyword, etc.) can be collected, and the analysis server 120 calculates a positive index and a negative index using an emotion dictionary, which is at least one group of words related to emotion previously stored for the contents to be analyzed. By calculating, the emotion index can be calculated. As a specific example, the analysis server 120 may calculate a sentiment index using a CNN algorithm, a BERT algorithm, a polarity detection (positive index, negative index), and a support vector machine (SVM) algorithm.

Alternatively, the analysis server 120 may use an emotion dictionary consisting of previously stored word groups for each emotion. That is, based on the emotion dictionary and targeting a word or word pair extracted from the content, a PMI index between the reference and the target may be calculated, thereby calculating an emotion index value for the corresponding content. That is, by calculating the index for each emotion of the content, and combining them, the emotion index for the corresponding content may be calculated.

That is, it is preferable that the analysis server 120 calculates the emotional index of the content in which the advertisement prepared by the advertiser or the like will be displayed, and the advertisement supply server 32 provides the corresponding advertisement for the content having an emotional index equal to or greater than a certain value. Do. Here, the content having an emotional index less than a certain threshold indicates that a number of profanity or abusive language are included, and the content having an emotional index exceeding the predetermined threshold indicates that there is no or almost no profanity or profanity.

As described above, according to an embodiment of the present invention, when an advertisement is displayed, when the content including the advertisement displayed includes low-quality content, that is, content such as sensational, violent, extreme unilateral political, etc., the brand value of the advertisement product Can be prevented from falling.

Meanwhile, FIG. 6 is a configuration diagram of an advertisement supply server according to an embodiment of the present invention.

As shown in FIG. 6, the advertisement supply server 32 includes an advertisement mediator control device 321 for managing advertisement mediators, and an advertisement bidding apparatus for processing advertisement bids of advertisers to prepare advertisements displayed through advertisement mediators. A data management device that provides bidding information referenced to the advertisement bidding to the advertisement bidding device 322 using log data collected by the advertisement intermediary, specifically from the advertisement consumer terminal 20 323 may be included.

The advertisement mediator management apparatus 321 may be a means for receiving advertisements in the content and providing or managing advertisement mediators that display advertisements. The advertisement mediator can perform a series of operations of requesting, receiving, and displaying advertisements, and not only collects user behavior history (or log data), and provides it to the advertisement supply server 32 or the advertisement mediation server 100 can do.

The advertisement bidding device 322 is a means for processing advertisement bidding of advertisers, and initiates an advertisement bidding according to an advertisement request transmitted through the advertisement intermediary management device 321, and sends the successful advertisement through the advertisement bidding. By responding to 321, it can be provided to the advertisement consumer terminal 20.

The data management apparatus 323 may provide the advertisement bidding apparatus 322 with bidding information referenced for advertisement bidding by using log data collected on advertisement consumers through the advertisement consumer terminal 20.

At this time, the advertisement intermediary server 100, specifically the analysis server 120, calculates an emotional index for the corresponding content, but varies the advertisement bid price according to the calculated emotional index, and the advertisement bidding device 322 initiates the advertisement bidding. You can bid on. Of course, in this case, the corresponding content may be according to an extended keyword and/or a category set through the advertisement mediation server 100.

As described above, when content with a low emotional index indicates that the content is of low quality, and indicates that the content with a high emotional index is not of low quality, the advertisement mediation server 100, specifically the analysis server 120 has a high emotional index. The more the advertisement bids are raised and bid, so that the brand value can be maintained above a predetermined level.

Meanwhile, a general search server (not shown) provides search terms for which the number of search requests rapidly increases in real time, that is, a hot issue trend search word, and the advertisement mediation server 100, specifically, the setting server 130 uses the hot issue trend search word. Can be added to extended keywords. Here, the search server refers to a search engine that receives a search result request as a query and responds to the search result.

Regardless of the keyword input by the advertiser, the setting server 130 may add a predetermined number of the hot issue trend search words to the expanded keyword so that the advertisement can be displayed in the content of interest to the advertisement consumer.

Consequently, even if an advertiser does not separately set an advertisement keyword, the advertisement supply server 32 can increase advertisement efficiency by providing advertisements to and displaying advertisements to contents whose interest of advertisement consumers has recently increased.
