In recent years, wireless communication terminals for performing wireless communication have become widespread. In particular, mobile phone terminals equipped with functions as telephones have become widespread due to the convenience of being able to make and receive calls easily regardless of location and time, as well as higher functionality, lower prices, and wider call areas. The momentum is remarkable. In particular, in recent mobile phone terminals, those equipped with information transmission / reception functions such as e-mail and those capable of transmitting / receiving position information using GPS (Global Positioning System) have become mainstream. Here, the terminal means a terminal device.

[0003] On the other hand, many recent mobile phone terminals have an Internet connection function as well as a personal computer (hereinafter referred to as a personal computer! /). PCs and mobile phone terminals equipped with this Internet connection function are generally equipped with a web browser, and can access various Internet sites via the Internet.

[0004] For example, by accessing a search site where a keyword search is possible by a search engine and inputting a keyword as query information, various information related to the keyword can be obtained. In addition, for example, you can obtain use information for the day by accessing a use distribution site operated and managed by a newspaper company.

Disclosure of the invention

Problems to be solved by the invention

[0008] However, even if a keyword is input to the search site, there is a case where advertisement information with high advertising effect is not provided accurately to the user. For example, the advertising information that the user is most interested in is not directly related to the keyword entered by the user. In this case, even if the user inputs a keyword, advertisement information that attracts the user's interest is not provided, which is useful for both the user and the advertiser of the advertisement information.

On the other hand, even in such a case, the advertisement information is often directly related to another keyword related to the keyword input by the user. Therefore, it is beneficial for users and advertisers to provide not only advertising information directly related to the keyword entered by the user but also advertising information directly related to another keyword related to the keyword. In some cases, a high advertising effect can be obtained.

[0010] The present invention has been made in view of the above circumstances, and is not directly related to input query information by extracting advertisement information related to other query information related to query information. It is structured to be able to provide advertising information, which is beneficial for users, It is an exemplary problem to provide an advertisement information providing method, an advertisement information providing system, an advertisement information providing program, and a database used for them that are high for advertisers and can exert an advertising effect.

Means for solving the problem

[0011] In order to solve the above-described problem, an advertisement information providing method as an exemplary aspect of the present invention includes a step of acquiring query information input via a communication terminal, and another associated with the query information. The query information of the query database is extracted, the advertisement information associated with other query information is extracted from the advertisement database, and the extracted advertisement information is provided.

[0012] Even advertisement information that is not related to the acquired query information can be extracted as long as the advertisement information is related to other query information related to the acquired query information. Therefore, the range of selection of advertisement information to be provided is widened, and it is possible to provide advertisement information that is even more useful to users and advertisers of advertisement information.

For example, when the acquired query information is “car”, the query information “car” and the query information “drive” are associated with each other, and the advertisement information of “driving school” is included in the query information “driving”. If it is associated, the advertising information of “driving school” is associated with the query information “car”, and even in this case, the advertising information of “driving school” can be extracted and provided.

[0014] The acquired query information may be a keyword input via a communication terminal.

[0015] Advertisement information can be extracted and provided based on an input keyword, for example, a keyword input in a search site. Therefore, the advertisement information can be extracted and provided based on the item searched by the user of the communication terminal, that is, the item of interest.

[0016] In this case, even advertisement information that is not related to the input keyword can be extracted and provided as long as it is advertisement information related to another keyword related to the keyword. Therefore, the range of selection of advertisement information to be provided is widened, and advertisement information that is more useful for both users and advertisers of advertisement information can be provided.

[0017] The advertisement information providing method determines whether the advertisement information ranking information is based on the degree of association between the acquired query information and other query information and the degree of association between the other query information and advertisement information. You may further have the step which produces | generates information.

[0018] Since the ranking information of the advertisement information is generated, the priority of the advertisement information to be provided can be set based on the ranking information. Here, the priority means display order of advertisement information to be provided, display size, display emphasis, display frequency, display time, display probability, and the like.

[0019] Since the ranking information is generated based on the degree of association between the acquired query information and other query information and the degree of association between the other query information and advertisement information, It is possible to preferentially provide advertising information having a high relevance to other query information having a high level.

[0020] For example, when the acquired query information is "car", advertising information related to "driving" as other query information highly related to "car" is used as other query information having low relevance. The priority can be higher than the advertising information related to “music”. Furthermore, among the advertising information related to “driving”, the advertising information of “driving school” having high relevance may be set to a higher priority than the advertising information of “parking lot” having low relevance. it can.

[0021] The advertisement information providing method may further include a step of updating the degree of association between the acquired query information and other query information in the query database each time the query information is acquired.

[0022] Since the degree of association between query information is updated each time new query information is acquired, the latest and optimum association can always be performed.

[0023] When the advertisement information providing method acquires a plurality of pieces of query information input via the same communication terminal, the method further includes a step of strengthening a degree of association between the plurality of pieces of query information in the query database. May be.

[0024] A plurality of pieces of query information input via the same communication terminal are input by the same user, and are often closely related to each other and attract the user's interest. By strengthening the degree of association between multiple pieces of query information (ie, making the relationship high), the relationship between the query information in the query database can be set to the optimum state.

[0025] A method in which the advertisement information providing method acquires terminal identification information for identifying a communication terminal. You may have further.

[0026] Since the terminal identification information is acquired, it is possible to identify the terminal through which the acquired query information is input. Therefore, when a plurality of pieces of query information are acquired, it is possible to easily determine whether they are input through the same communication terminal or different communication terminals.

Thereby, for example, a query database can be created for each user (that is, for each terminal identification information), and individual associations between query information can be set independently in each query database.

[0028] An advertisement information providing system as another exemplary aspect of the present invention includes a query database configured by associating a plurality of query information with each other, and an association between query information and advertisement information. An advertisement database, a query information acquisition unit for acquiring query information input via a communication terminal, a related query information extraction unit for extracting other query information associated with the query information from the query database, and other An advertisement information extraction unit that extracts advertisement information associated with the query information from the advertisement database, and an advertisement information provision unit that provides the extracted advertisement information.

[0029] Even advertisement information that is not related to the acquired query information can be extracted if it is advertisement information related to other query information related to the acquired query information. Therefore, the range of selection of advertisement information to be provided is widened, and it is possible to provide advertisement information that is even more useful to users and advertisers of advertisement information.

[0030] The query database may include query relation information indicating a degree of relation between a plurality of pieces of query information.

[0031] With the query relevance information, the relevance between the acquired query information and other query information in the query database can be managed. Therefore, for example, other query information that is highly related to the acquired query information (for example, “car”) (for example, “driving”) and other query information that is not highly related (for example, “music”) are individually managed. can do. For example, the priority of other query information can be set based on the query relevance information, and other query information can be extracted according to the priority.

[0032] An advertisement database that measures the degree of relevance between query information and advertisement information You may have sex information.

[0033] With the advertisement relevance information, the relevance between the query information and the advertisement information can be managed. Thus, for example, advertising information that is highly relevant to query information (eg “driving”) (for example, advertising information for “driving school”) and low-relevance! Advertising information (eg, advertising information for “parking”) Can be managed individually. For example, the priority order of the advertisement information can be set based on the advertisement relevance information, and the advertisement information according to the priority order can be provided.

[0034] Here, the degree of relevance between the query information and the advertisement information is, for example, the level of the bid (advertisement cost) bid by the advertiser who wants to provide the advertisement information for the query information. May be.

[0035] The advertisement information providing system generates ranking information of advertisement information based on the degree of association between the acquired query information and other query information and the degree of association between the other query information and advertisement information. You may further have a ranking information generation part.

[0036] Since the ranking information of the advertisement information is generated, the priority of the advertisement information to be provided can be set based on the ranking information. Here, the priority means display order of advertisement information to be provided, display size, display emphasis, display frequency, display time, display probability, and the like.

[0037] Since the ranking information is generated based on the degree of association between the acquired query information and other query information and the degree of association between the other query information and advertisement information, It is possible to preferentially provide advertising information having a high relevance to other query information having a high level.

[0038] The advertisement information providing system may further include a terminal identification information acquisition unit that acquires terminal identification information for identifying a communication terminal.

[0039] Since the terminal identification information is acquired, it is possible to identify the terminal through which the acquired query information is input. Therefore, when a plurality of pieces of query information are acquired, it is possible to easily determine whether they are input through the same communication terminal or different communication terminals.

[0040] Thereby, for example, a query database is stored for each user (ie, for each terminal identification information) You can create individual associations for each query information in each query database.

[0041] An advertisement information providing program as still another exemplary aspect of the present invention includes a query information acquisition unit that acquires query information input via a communication terminal, and another query associated with the query information.

[0042] Even advertisement information that is not related to the acquired query information can be extracted as long as the advertisement information is related to other query information related to the acquired query information. Therefore, the range of selection of advertisement information to be provided is widened, and it is possible to provide advertisement information that is even more useful to users and advertisers of advertisement information.

[0043] The advertisement information providing program causes the computer to acquire the terminal identification information acquisition unit for acquiring the terminal identification information for identifying the communication terminal, the degree of association between the acquired query information and other query information, and other Based on the degree of association between the query information and the advertisement information, it may further function as a ranking information generation unit that generates ranking information of advertisement information.

[0044] Since the terminal identification information is acquired, it is possible to identify through which terminal the acquired query information is input. Therefore, when a plurality of pieces of query information are acquired, it is possible to easily determine whether they are input through the same communication terminal or different communication terminals.

[0046] Since ranking information of advertisement information is generated, the priority of advertisement information to be provided can be set based on the ranking information. Here, the priority means the display order of the advertisement information to be provided, the display size, the display emphasis, the display frequency, the display time, the display probability, and the like. [0047] Since the ranking information is generated based on the degree of association between the acquired query information and other query information and the degree of association between the other query information and advertisement information, It is possible to preferentially provide advertising information having a high relevance to other query information having a high level.

FIG. 4 is a block diagram showing an outline of the internal configuration of the database server 6. The database server 6 has a storage device 20 inside. Since the configuration of the storage device 20 is the same as that of the storage device 12, the description thereof is omitted. The storage device 20 stores a keyword database (query database, part of the database) 22 and an advertisement data base (part of the database) 24. In this embodiment, the advertisement management Sano and the database server 6 are described separately. Of course, one server has both the advertisement management Sano function and the database server 6 function. It may be. The ability to explain the following keyword database 22 and advertisement database 24 as separate databases. Of course, these databases can be configured as one database! /.

[0067] The keyword database 22 is a database that includes a plurality of keywords 22a to 22h and keyword relevance information (query relevance information) 23a to 23f that indicates the degree of relevance between the keywords. is there. FIG. 5 is a structural diagram showing the data structure of the keyword database 22.

[0068] The keyword 22a in the keyword database 22 is associated with the keywords 22b and 22c. The degree of relevance between keyword 22a and keyword 22b is The index is indicated by the connectivity information 23a, and the degree of relevance between the keyword 22a and the keyword 22c is indicated by the keyword relevance information 23b.

[0069] For example, when the keyword 22a is "car", the keyword 22b is "driving", and the keyword 22c is "music", it is determined that "car" and "driving" are highly relevant, and the keyword relevance Information 2 3a is set to a large number (for example, 80 points). Conversely, “car” and “music” are judged to have low relevance, and the keyword relevance information 23b is set to a small value (for example, 20 points).

[0070] Similarly, it is determined that the keyword 22d “fashion” and the keyword 22e “clothes” are highly relevant, and the keyword relevance information 23c is set to 90 points, for example, and the keyword 22d “fashion” and the keyword 22f “ “Italy” is judged to have low relevance, and keyword relevance information 23d is set to 40 points, for example.

[0071] In addition to the keyword 22a "car", the keyword 22c "music" is associated with the keyword 22g "rock", the keyword 22h "record", and the like.

, 23f is set.

Here, it is determined that the keyword 22a “car” and the keyword 22d “fashion” are not related, and are not related to each other. Therefore, the keyword relevance information between these two keywords 22a and 22d is set.

[0073] The keyword database 22 is created based on the concept of synonyms. For example

A keyword database may be created by determining the degree of relevance between keywords based on a commercially available synonym dictionary and setting keyword relevance information based on the degree of relevance.ヽ.

[0074] Also, keywords are collected from various Internet sites connected to the Internet W, and it is judged that the keywords collected from the same site are highly related to each other, and the keyword relevance information for each other is set high. Even so.

[0075] The advertisement database 24 includes a plurality of keywords 22a to 22h, a plurality of advertisement information A to J, and bid price 24a to 25j as advertisement relevance information that indicates the degree of relevance between the keyword and the advertisement information. A database configured. FIG. 6 is a structural diagram showing the data structure of the advertisement data base 24. [0076] The keyword 22a "car" in the advertisement database 24 is associated with advertisement information A "car dealer advertisement" and advertisement information B "repair shop advertisement". The advertisement information A and B is advertisement information that each advertiser wants to provide to the mobile phone terminal 2 and is determined in advance between the advertiser and the operator of the advertisement information providing system S. It is a thing.

[0077] The degree of relevance between keyword 22a and advertisement information A is indicated by advertisement relevance information 24a, and the degree of association between keyword 22a and advertisement information B is indicated by advertisement relevance information 24b. It is configured as follows. The advertisement relevance information 24a, 24b is information indicating the strength of the relevance between the keyword 22a and the advertisement information A, B.

[0078] For example, the advertisement relevance information 24a, 24b may be determined arbitrarily by the operator of the advertisement information providing system S. Advertising information provided if the relationship between keyword 22a “car” and advertising information A “car dealer advertising” is higher than keyword 22a “car” and advertising information B “repair shop advertising” The operator of the system S may determine the advertisement relevance information 24a to be a larger value than the advertisement relevance information 24b.

[0079] However, in the present embodiment, bid prices (advertisement costs) 24a and 24b that are determined in advance by the advertiser and the operator of the advertisement information providing system S are set as the advertisement relevance information, and the keyword On the other hand, advertising information with a high bid is considered highly relevant to the keyword, and the advertising relevance information is set to a large number. Setting bids as advertising-related information can contribute to providing advertisers with equitable advertising information.

[0080] Of course, as the advertisement relevance information, a click expectation value indicating the probability that detailed information will be browsed when the advertisement information provided at the bid price described in this embodiment is provided is set. Also good. Since the click expectation value indicates the degree of popularity of the advertisement information, setting the click expectation value as advertisement relevance information can contribute to providing advertisement information useful for the user. Of course, the product of the expected click value and bid price may be set as the ad relevance information.

Specifically, an advertiser who desires to provide an advertisement to the mobile phone terminal 2 first sets a keyword that is determined to be highly relevant to his / her advertisement information. For example, an advertiser who sells a car sets the keyword 22a “car” for his advertising information A. This The advertiser then sets his advertising information A for keyword 22a at a bid price of 24a. The bid unit price 24a is, for example, “50 yen”. Of course, this advertiser may set another keyword “engine” (not shown) for his / her advertising information A at a different bid price “20 yen” (not shown).

On the other hand, another advertiser who operates the repair shop sets keyword 22a “car” for his / her advertisement information B at a bid price 24b. The bid price 24b is, for example, “20 yen”. As a result, advertisement information A and B are associated with keyword 22a by bid prices (advertisement-related information) 24a and 24b, respectively.

Here, the bid prices 24a and 24b may be advertising costs charged to each advertiser every time the advertising information A and B is provided to the mobile phone terminal 2. Further, it may be an advertising fee charged when the detailed information of the provided advertising information A and B is viewed by the user of the mobile phone terminal 2.

[0084] Similarly, for keyword 22b "driving", advertising information C "driving school advertising" and advertising information D "parking parking advertisement" are set at bid prices 24c and 24d, respectively. Keywords 22c to 22h are set with advertising information E to J, respectively, with bids 24e to 24j.

The CPU 14 is a main part of the advertisement management Sano, and performs various arithmetic processes in cooperation with the storage device 12 and the main memory 16. Based on the command from the advertisement information provision program 18, the CPU 14 extracts a keyword acquisition unit (query information acquisition unit) 14a, a terminal identification information acquisition unit 14b, a related keyword extraction unit (related query information extraction unit) 14c, and related advertisement information extraction. Functions as the unit 14d, the ranking information generation unit 14f, and the advertisement information providing unit 14g.

The keyword acquisition unit 14a has a function of acquiring a keyword 8f as query information input via the mobile phone terminal 2 from the search site server 8 via the Internet W. Of course, the keyword acquisition unit 14a may acquire the keyword 8f directly from the mobile phone terminal 2 via the Internet W instead of from the search site server 8.

The terminal identification information acquisition unit 14b is for acquiring terminal identification information 2b for identifying the mobile phone terminal 2. The terminal identification information 2b may be a telephone number assigned to each mobile phone terminal 2 or a mobile phone terminal 2 for identifying the user of the mobile phone terminal 2. It may be user information managed by the telephone company.

[0088] The terminal identification information 2b is transmitted from the mobile phone terminal 2 or the base station Z to the advertisement management server 4 via the Internet W, and is acquired by the terminal identification information acquisition unit 14b. At this time, since the keyword 8f and the terminal identification information 2b are acquired in association with each other, it is possible to identify the terminal power transmitted by the acquired keyword 8f.

[0089] Further, the terminal identification information acquisition unit 14b may have a function of acquiring the terminal position information 2p and the terminal position information measurement time tm transmitted from the mobile phone terminal 2. Such information (terminal location information 2p and terminal location information measurement time tm) can be used to set priorities when providing advertisement information.

[0090] For example, the priority of the advertisement information to be provided is set based on the distance between the position of the advertiser providing the advertisement information and the terminal position information 2p, or a new terminal position at the terminal position information measurement time tm is set. Information Advertiser advertiser information close to 2p can be preferentially provided.

[0091] The related keyword extraction unit 14c has a function of extracting the other keywords associated with the keyword 8f acquired by the keyword acquisition unit 14a, as a medium force of the keyword database 22. For example, when the acquired keyword 8f is the keyword 22a “car”, the related keyword extraction unit 14c searches the keyword database 22 for other keywords 22b “driving”, keyword 22c “music”, etc. To extract. Of course, the keyword 22d “fashion” not associated with the keyword 22a “car” is not extracted.

[0096] The related advertisement information extraction unit 14d has a function of extracting, from the advertisement database 24, advertisement information associated with another keyword associated with the acquired keyword 8f. For example, if the acquired keyword 8f is the keyword 22a “car”, the advertisement information C, D associated with the keyword 22b “driving” as another keyword and the advertisement information associated with the keyword 22c “music” E is extracted from the advertisement database 24.

[0097] The related advertisement information extraction unit 14d has a function of extracting both the advertisement information associated with the acquired keyword 8f and the medium of the advertisement database 24. For example, when the acquired keyword 8f is the keyword 22a “car”, the advertisement information A and B associated therewith is extracted as the medium of the advertisement database 24.

[0098] The ranking information generation unit 14f uses the ranking information hA to hE of the extracted advertisement information A to E as the degree of association between the keywords 22a to 22c and the association between the keywords 22a to 22c and the advertisement information A to E. Based on the degree of! /, It has a function to generate.

[0099] For example, the ranking information may be defined by the following formula (1).

Keyword relevance information X bid (1)

[0100] Specifically, if the acquired keyword 8f is the keyword 22a “car”, defining the keyword relevance information for the keyword 22a itself of the keyword 22a as 100 points, the keyword related to the keyword 22a “car” Sex information

Keyword 22a "car": 100 points

Keyword 22b “Driving”: 80 points Keyword 22c "music": 20 points

It is. And the bid of advertising information for each keyword is

Against keyword 22a "car"

Advertising information A: 50 yen

Advertising information B: 20 yen

Against keyword 22b “driving”

Advertising information C: 60 yen

Advertising information D: 20 yen

Against keyword 22c "music"

Advertising information E: 70 yen

It has become. Therefore, the ranking information hA to hE of the advertisement information A to E for the acquired keyword 22a “car” is generated by being calculated by the following equation.

[0101] hA = 100 points> 50 yen = 5000

hB = 100 points> (20 yen: = 2000

hC = 80 points> 60 yen = 4800

hD = 80 points> 20 yen = 1600

hE = 20 points> 70 yen = 1400

Thereby, the priority of the advertisement information A to E is set higher in the order of A, C, B, D, E. Therefore, the priority of advertising information C “driving school advertising”, which is directly related to the acquired keyword 22a, is higher than the advertising information B “repair shop advertising” directly related. Is set.

[0102] The advertisement information providing unit 14g has a function of providing the extracted advertisement information A to E and the ranking information hA to hE in association with each other. Here, providing is a concept including transmitting to the search site server 8 via the Internet W and transmitting directly to the mobile phone terminal 2 via the Internet W and the base station Z.
