The present invention relates to an advertising method and system, and more particularly, to an advertising method and system that can provide a suitable advertisement by extracting a keyword based on the conversation content of the messenger.

In recent years, as the spread of wired and wireless communication services such as mobile communication and high-speed Internet has become commonplace, almost all actions that have been performed in the past through off-line have been replaced by online actions. In particular, the market for information service and e-commerce services through online is growing day by day, and this trend is expected to accelerate.

Accordingly, corporate marketing tools are also rapidly changing in the importance of online. In particular, in the case of advertisements, which are most important in marketing means, companies are forced to escape from one-dimensional advertisements through TV, newspapers, magazines, flyers, outdoor facilities, etc. to promote their products. We strive to provide more effective online advertising.

The most basic form of such an online advertisement is to insert a banner containing a promotional image on a web page and have the user click on the banner. Such banner advertisements are easy to implement and relatively easy to access by users, but are still widely used, but it is difficult to attract attention to the contents of advertisements because they target a large number of unspecified users. In addition, there is a problem that the success rate of advertisements that leads to actual purchases is relatively low compared to the number of clicks.

Other forms of conventional online advertising include pop-up advertisements, event-type advertisements, research-type advertisements, and the like. Pop-up advertisements display pop-up advertisements when the user selects a particular web page. This has similar advantages to the banner advertisements mentioned above, but also has the disadvantages of banner advertisements. In particular, if a pop-up advertisement that is not a field of interest frequently appears from the user's point of view, it may have an adverse effect on the content of the advertisement.

Event-type advertising or research-type advertising is to provide related advertisements to users who participated in the event or research after holding an event or research related to a specific field. In the case of such event-type advertising or research-type advertising, the advertisement effect can be somewhat improved in that the advertisement can be provided to users who are relatively interested in the contents of the advertisement. However, it is also difficult to pinpoint the user's interests only by participating in events or research.

On the other hand, the utilization of instant messenger (hereinafter referred to as messenger) is increasing. Unlike e-mail, messenger enables live chat with the other party, and if you run a simple messenger window, you can talk without running a web browser. In addition, since messenger can communicate freely regardless of the distance between users, it is highly economical and provides various additional functions such as file exchange or sharing between users and interworking with web pages. can do.

Because of these advantages, most of today's workers are using messengers at home or at school. In some cases, messengers are also used for business operations in conjunction with strict security systems. Therefore, if the advertisement is provided using such messenger, the effect is expected to be very high, but at the moment, the advertisement is inserted into the messenger window by inserting a banner advertisement or a pop-up advertisement targeting an unspecified number regardless of the interest of the messenger user. It is true that you are staying.

The category map may mean a map in which categories are defined for each information field. The category keyword table is a table that defines category keywords and their rank scores belonging to each category defined by the category map.

3 is an exemplary diagram illustrating an example of a category map stored in the category information database 134.

As shown in FIG. 3, the category map CM defines a category for each information field. In addition, the category map may define a depth of a category according to the relevance and range of information. That is, a specific category may have its upper category or its subcategory according to the definition of the category map.

For example, the overall category map CM is divided into categories such as "game", "education", "corporate", "society", "politics", and "entertainment". Among these, the category has sub-categories such as "PC game", "game machine", "online game", "game magazine", and the like. In addition, the "enterprise" category may have sub-categories such as "construction", "finance", "shipping", etc., of which the "shipping" category may have "container", "bulk", "bunker", and so on. have.

4A and 4B are exemplary diagrams for explaining examples of a category keyword table stored in the category information database 134. FIG. 4A shows an example of a category keyword table in which category keywords of the "PC game" category are defined. 4B shows an example of a category keyword table that defines category keywords of the “bulk” category.

First, referring to FIGS. 3 to 4A, the category keyword table CTa defines a category keyword of the category "PC game" and a rank score corresponding to each category keyword. At this time, the category "PC game" exists in the "all"-> "game"-> "PC game" in the category map (CM). Here, "->" indicates moving to a lower category.

According to the category keyword table CTa, category keywords such as PC game (rank score 20 points), StarCraft (rank score 12 points), FIFA Online (score score 7 points), and the like belong to the "PC game" category.

3 to 4B, the category keyword table CTb defines a category keyword of the “bulk” category and a rank score corresponding to each category keyword. At this time, the "bulk" category exists in the category map (CM) "all"-> "company"-> "shipping"-> "bulk".

According to the category keyword table CTb, the "Bulk" category includes MV (rank point 3 points), Cargo (rank point 3 points), TCT (rank point 3 points), DWT (rank point 2 points), and L / D rate (rank Category keywords such as 1 point) and L / D port (1 point).

The advertisement information database 136 stores advertisement information corresponding to each category stored in the category information database 134. In this case, the advertisement information corresponding to the category may include a category / ad table.

5 is an exemplary diagram for describing an example of a category / advertisement table stored by the advertisement information database 136.

As shown in FIG. 5, the category / advertisement table CAT stores advertisement information corresponding to a category. In this case, the advertisement information may include an advertiser name, an advertisement banner, a URL to be moved when the banner is clicked, and the like. Such advertisement information may be registered from the advertiser terminal 40 through the advertisement registration module 126.

That is, the advertiser may access the advertisement registration module 126 of the advertisement providing system 100 through the advertiser terminal 40 and select and input a category to which his advertisement corresponds. At this time, the advertisement registration module 126 provides the user interface for viewing the category map to the advertiser terminal 40 so that the advertiser can easily select a category. In addition, the advertisement registration module 126 stores the advertisement advertisement information received from the advertiser terminal 40 in the category / advertisement table CAT of the advertisement information database 136 in association with the advertisement of the advertiser.

In the example illustrated in FIG. 5, the case of providing a banner advertisement is described, but an advertisement that may be provided corresponding to a category includes various types of advertisements currently used, and the category / advertisement table CAT provides each type of advertisement. You can store the necessary information.

Meanwhile, the management information database 138 stores management information according to providing an advertisement to the messenger client 10 of the user. For example, the management information may store information such as advertisement provision status, banner click count, membership registration through advertisement, actual purchase, advertisement success rate, and the like. Such management information may be provided to the advertiser.

The keyword extraction module 112 receives the contents of the messenger conversation from the messenger server 30 or the messenger client 10 and extracts a keyword. In other words, it extracts keywords that can grasp the user's interest from the contents of the user's messenger conversation. When extracting keywords, keywords can be extracted based on nouns. For example, the keyword extraction module 112 may extract keywords such as "game", "bulk", "game machine", "competition contest", "study abroad", "study language".

When extracting keywords, the keyword extracting module 112 may refer to a standard keyword mapping table in preparation for a communication language frequently used in chatting, a different Korean expression of a sweetfish, a foreign language, a part of speech other than a noun, and the like. The standard keyword mapping table refers to a table capable of mapping words of similar meaning that may exist in a messenger sentence to specific standard words (eg, specific nouns). In the standard keyword mapping table, standard keywords corresponding to various kinds of words are defined.

For example, using the standard keyword mapping table, "stark" is regarded as the same word as Starcraft. Therefore, if "stark" is detected in the sentence, the keyword extraction module 112 refers to the representative keyword mapping table and refers to it. "Eating" or "What to eat?" In the sentence "what to eat" or "what to eat?" Is not a noun, so search the representative keyword mapping table and search for "restaurants." The noun "may be extracted as a keyword. The standard keyword mapping table may be provided by the keyword extraction module 112 by itself, or may be provided in a specific database and then searched for the corresponding database.

The category keyword extraction module 114 is provided with a keyword extracted from the keyword extraction module 112, searches the category information database 134, and extracts a category keyword corresponding to the extracted keyword. For example, if the extracted keywords are "starcraft" and "MV", the category keyword extraction module 114 extracts the corresponding category keywords "starcraft" and "MV" from the category information database 134.

The operation module 116 inquires the rank score corresponding to the category keyword extracted by the category keyword extraction module 114, and adds the retrieved rank score to the category rank score of the category to which the category keyword belongs. For example, if the extracted keyword is "StarCraft", the calculation module 116 detects 12 points, which are rank scores of "StarCraft" defined in the category keyword table CTa, and 12 to the "PC Game" category rank score. Add points. Accordingly, the category rank score of the category corresponding to the keyword extracted from the contents of the messenger conversation of the user is increased by the operation module 116.

The category rank score for each category added by the calculation module 116 may be recorded in a category rank score table stored in the category information database 134. In the category rank score table, category rank scores for each category are accumulated and recorded. The cumulative details are also recorded.

The messenger conversation content analysis process (that is, the process of accumulating the rank score by extracting the keyword according to the messenger conversation content and finding the rank score of the category keyword corresponding to the extracted keyword and adding it to the rank score of the corresponding category) is predetermined. It is performed repeatedly for time. In this case, the setting time may be divided into a real time analysis time and an accumulation analysis time according to a mode set by the mode setting module 118.

The mode setting module 118 sets a messenger conversation content analysis mode. The messenger conversation content analysis mode includes a real time analysis mode or an accumulation analysis mode. The mode setting module 118 may set a mode by selecting a desired mode from a user, an advertiser, or a service provider.

The real time analysis mode refers to a mode in which a user analyzes the contents of a messenger conversation in real time when a user performs a chat through the messenger client 10. In this real-time analysis mode, it is possible to change the type of advertisements according to the user's interests through real-time analysis. In the real-time analysis mode, you can also set the real-time analysis time. In this case, the real time analysis time may mean a time for deciding how long the real time analysis is performed to provide an advertisement. This real time analysis time may be set by the user, the advertiser, or the service provider through the mode setting module 118. For example, a user or an advertiser may access the mode setting module 118 and set the real time analysis time to "30 minutes", in which case, the advertisement providing system 100 may real-time messenger conversation content in units of 30 minutes in real time. Can be analyzed to provide advertising.

The accumulation analysis mode refers to a mode in which an analysis result of a messenger conversation content of a user may be accumulated and provided for a specific period of time. In this accumulation analysis mode, the user may be provided with an advertisement that reflects the user's continuous interests. In the accumulation analysis mode, the accumulation analysis time can be set. The accumulation analysis time may mean a time for setting how long the analysis of the dialogue contents is accumulated and the advertisement is provided. This accumulation analysis time may be set by the user, the advertiser, or the service provider through the mode setting module 118. For example, a user or an advertiser may access the mode setting module 118 and set the accumulation analysis time to “6 months,” in which case, the advertisement providing system 100 analyzes the contents of the messenger conversation for 6 months to advertise. Can be provided.

The category rank score table stored in the category information database 134 is updated until a set time (for example, real time analysis time and accumulation analysis time) is reached. That is, the content of the conversation of the messenger is analyzed by the advertisement providing system 100 for a predetermined time, and accordingly, the rank score for each category is continuously accumulated.

The category extraction module 120 searches for the category rank score table managed in the category information database 134 after the setting time is finished after the messenger conversation content analysis process is repeatedly performed during the setting time, and at least one having the highest rank score. Extract the category of. In this case, one or more categories may be extracted. If there are a plurality of categories to be extracted, the category extraction module 120 extracts the categories in order of high rank score.

Meanwhile, the category extraction module 120 may apply a weight to a specific category according to preset weight information when the category is extracted. Here, the weight information is information set to weight a specific category according to the user's age, occupation, preference, etc., and may be set and managed by a weight information table stored in the category information database 134. Such weight information may be set by a user or may be set by an administrator or an advertiser.

For example, if a user is in his 30s and is a female, a weight of 10% may be set in the "cosmetics" category or the "skinny jeans" category. In this case, the messenger conversation content of the user is analyzed for a set time, and the category rank score of the "game" category is 30 points, the category rank score of the "cosmetics" category is 30 points, and the category rank score of the "skinny jeans" category is "28". Assuming that the weight is applied, the category rank score of the "cosmetics" category is 33 points, the category rank score of the "game" category is 30 points, and the category rank score of the "skinny jeans" category is "31". Will be. Therefore, if the weight is applied, the category rank score is considered to be high in the order of "cosmetics", "skinny jeans", and "games".

The advertisement information extraction module 122 extracts advertisement information corresponding to one or more categories extracted by the category extraction module 120 from the advertisement information database 136. That is, the advertisement information extraction module 122 extracts advertiser information corresponding to the extracted category, advertisement banner information, mobile URL information upon banner click, and the like.

When the advertisement information extraction module 122 extracts a plurality of advertisement information, the advertisement information extraction module 122 may provide advertisement providing information such as advertisement order, advertisement time, etc. to the advertisement information transmission module. The advertisement providing information may be preset by a system administrator, a user, an advertiser, and the like and stored in the advertisement information database.

The advertisement order may be defined as information defined regarding the order in which the advertisements are to be displayed. For example, the advertisement order may be defined to provide advertisement information in the order of categories having a high category rank score. The advertisement time is information defining the serving time of each advertisement. For example, the advertisement information of the category having the highest category rank score is defined as "one minute" and the advertisement information of the next higher category is "30 seconds" or the like. It can also be defined to refresh every "20 seconds." The advertisement providing information may be variously set.

The advertisement information transmission module 124 provides the advertisement information extracted by the advertisement information extraction module 122 to the messenger client 10. At this time, the advertisement providing information provided from the advertisement information extraction module 122 is also provided. Then, in the messenger client 10, an advertisement is output according to the advertisement providing information according to the corresponding advertisement information. Accordingly, the user can watch an advertisement related to the contents of the messenger conversation.

Meanwhile, the category rank score table stored in the category information database 134 is reset for the next messenger conversation content analysis after completion of transmission of advertisement information or after messenger conversation content analysis. In this case, the category rank score table may not be completely disappeared from the database unit 130 but may be transferred to the management information database 138 and stored and managed.

The control module 101 performs a function of totally controlling the interaction and data processing flow between the above-described modules. That is, the linkage operation between the modules and the linkage between the module and the database may be systematically controlled by the control module 101.
