[Technical field]

[0001] The present disclosure relates to a characteristic estimation device, a characteristic estimation method, and a program. [Background technology]

[0002] There is a technology that analyzes characteristics related to a user's consumption behavior in a communication network such as the Internet and provides information according to the user's characteristics. For example, Patent Document 1 discloses a characteristic estimation server that estimates the characteristics of a user based on the user's questionnaire results and behavioral history.

[0003] The characteristic estimation server disclosed in Patent Document 1 classifies multiple target users who answered a questionnaire into one of multiple predetermined characteristics based on the questionnaire results, and identifies teacher users whose behavioral history meets a predetermined standard. The characteristic estimation server then estimates the characteristics of the estimated user using a characteristic estimation model that uses behavioral information extracted from the behavioral history of the teacher users as explanatory variables and the characteristics of the teacher users as objective variables.

[0004] [Patent Document 1] JP 2020-35409 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the conventional technology, whether or not there is a difference in consumption behavior between groups of users classified into the same characteristics is uncertain. For example, the invention disclosed in Patent Document 1 specifies teacher users from target users classified based on questionnaire results, so it is not guaranteed that there is a difference in consumption behavior characteristics of target users classified into different characteristics.

[0010] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. In this specification and the drawings, components having substantially the same functional configurations are denoted by the same reference numerals, and redundant description will be omitted.

[0011] [Embodiment] An embodiment of the present disclosure is a consumption behavior characteristic estimation system that estimates characteristics related to a user's consumption behavior (hereinafter also referred to as "consumption behavior characteristics"). The consumption behavior characteristic estimation system estimates a user's consumption behavior characteristics based on a web browsing history that represents the user's web browsing history and consumption behavior performance data that represents the performance of the user's consumption behavior. Note that a user for whom a consumption behavior characteristic is to be estimated is also referred to as a "target user."

[0012] In this embodiment, the target users are customers whose information is held by the entity (such as a company, organization, or individual) using the consumption behavior characteristic estimation system. However, the target users are not limited to customers of companies, etc., and any users may be the target users as long as their web browsing history and consumption behavior performance data can be obtained.

[0013] The consumer behavior characteristic estimation system estimates purchasing speed data representing the purchasing speed of the target user and listening degree data representing the listening degree of the target user based on the web browsing history and the consumer behavior performance data. The consumer behavior characteristic estimation system also determines the consumer behavior characteristics of the target user based on the purchasing speed data and listening degree data estimated for the target user. Therefore, the consumer behavior characteristic estimation system can estimate the consumer behavior characteristics of the target user based on data representing the performance of the consumer behavior performed by the target user.

[0014] <Overall configuration of the consumer behavior characteristic estimation system> The overall configuration of a consumption behavior characteristic estimating system in this embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the overall configuration of a consumption behavior characteristic estimating system in this embodiment.

[0015] 1, a consumption behavior characteristic estimating system 1 in this embodiment includes a characteristic estimating device 10 and a user terminal 20. The characteristic estimating device 10 and the user terminal 20 are connected to each other so as to be able to communicate data with each other via a communication network N1 such as a LAN (Local Area Network) or the Internet.

[0016] The characteristic estimation device 10 is an information processing device such as a personal computer, a workstation, or a server that estimates a consumption behavior characteristic of a target user in response to a request from a user terminal 20. The characteristic estimation device 10 estimates a consumption behavior characteristic of the target user extracted from a web browsing history in response to a request from the user terminal 20, and transmits the estimation result to the user terminal 20.

[0017] The user terminal 20 is an information processing terminal such as a personal computer, a tablet terminal, or a smartphone operated by a user of the consumption behavior characteristic estimation system 1. In response to an operation by the user, the user terminal 20 transmits a request signal requesting estimation of a consumption behavior characteristic to the characteristic estimation device 10. In addition, the user terminal 20 receives an estimation result from the characteristic estimation device 10 and outputs it to the user.

[0018] 1 is merely an example, and various system configurations are possible depending on the application and purpose. For example, the characteristic estimation device 10 may be realized by a plurality of computers, or may be realized as a cloud computing service. In addition, for example, the consumption behavior characteristic estimation system 1 may be realized by a stand-alone information processing device having the functions that the characteristic estimation device 10 and the user terminal 20 should have.

[0019] <Hardware configuration of the consumer behavior characteristic estimation system> The hardware configuration of the consumption behavior characteristic estimating system 1 in this embodiment will be described with reference to FIG.

[0020] <Computer hardware configuration> The characteristic estimation device 10 and the user terminal 20 in this embodiment are realized by, for example, a computer. Fig. 2 is a block diagram showing an example of the hardware configuration of a computer 500 in this embodiment.

[0021] 2, the computer 500 includes a CPU (Central Processing Unit) 501, a ROM (Read Only Memory) 502, a RAM (Random Access Memory) 503, a HDD (Hard Disk Drive) 504, an input device 505, a display device 506, a communication I / F (Interface) 507, and an external I / F 508. The CPU 501, the ROM 502, and the RAM 503 form a so-called computer. Each piece of hardware of the computer 500 is connected to each other via a bus line 509. The input device 505 and the display device 506 may be connected to the external I / F 508 for use.

[0022] The CPU 501 is a calculation device that reads out programs and data from a storage device such as a ROM 502 or a HDD 504 onto a RAM 503 and executes processes, thereby realizing overall control and functions of the computer 500 .

[0023] The ROM 502 is an example of a non-volatile semiconductor memory (storage device) that can retain programs and data even when the power is turned off. The ROM 502 functions as a main storage device that stores various programs and data required for the CPU 501 to execute various programs installed in the HDD 504. Specifically, the ROM 502 stores boot programs such as a Basic Input / Output System (BIOS) and an Extensible Firmware Interface (EFI) that are executed when the computer 500 is started, and data such as an Operating System (OS) setting and a network setting.

[0024] The RAM 503 is an example of a volatile semiconductor memory (storage device) in which programs and data are erased when the power is turned off. The RAM 503 is, for example, a dynamic random access memory (DRAM) or a static random access memory (SRAM). The RAM 503 provides a working area in which various programs installed in the HDD 504 are expanded when the CPU 501 executes them.

[0025] The HDD 504 is an example of a non-volatile storage device that stores programs and data. The programs and data stored in the HDD 504 include an OS, which is basic software that controls the entire computer 500, and applications that provide various functions on the OS. Note that the computer 500 may use a storage device that uses a flash memory as a storage medium (e.g., an SSD (Solid State Drive) or the like) instead of the HDD 504.

[0026] The input device 505 includes a touch panel, operation keys or buttons, a keyboard or mouse, a microphone for inputting sound data such as voice, etc., which are used by the user to input various signals.

[0027] The display device 506 is composed of a display such as a liquid crystal display or an organic EL (Electro-Luminescence) display for displaying a screen, a speaker for outputting sound data such as voice, and the like.

[0028] The communication I / F 507 is an interface that connects to a communication network and enables the computer 500 to perform data communication.

[0029] The external I / F 508 is an interface with external devices, such as a drive device 510.

[0030] The drive device 510 is a device for setting the recording medium 511. The recording medium 511 here includes media that record information optically, electrically, or magnetically, such as a CD-ROM, a flexible disk, or a magneto-optical disk. The recording medium 511 may also include semiconductor memories that record information electrically, such as a ROM or a flash memory. This allows the computer 500 to read and / or write data from and to the recording medium 511 via the external I / F 508.

[0031] The various programs to be installed in the HDD 504 are installed, for example, by setting the distributed recording medium 511 in a drive device 510 connected to the external I / F 508 and reading out the various programs recorded in the recording medium 511 by the drive device 510. Alternatively, the various programs to be installed in the HDD 504 may be installed by being downloaded from a network different from the communication network via the communication I / F 507.

[0032] <Functional configuration of the characteristic estimation device> The functional configuration of the characteristic estimation device 10 in this embodiment will be described with reference to Fig. 3.

The contact medium data is stored in a contact medium table, which will be described later.

[0043] The subject information and contact medium data can be acquired from a questionnaire server or the like for carrying out market research. The characteristic estimation device 10 may acquire the subject information and contact medium data from the questionnaire server or the like periodically at a predetermined time interval, or may acquire the subject information and contact medium data from the questionnaire server or the like in response to a user request.

[0044] Product purchase data is stored in the product purchase data storage unit 106. The product purchase data is record data that represents the history of a customer's purchase of a product or service. The product purchase data is stored in a product purchase record table, which will be described later.

[0045] The product purchase data can be acquired, for example, from a credit card payment history, a purchase history of an EC (Electronic Commerce) site that electronically sells products or services, etc. The characteristic estimation device 10 may acquire the product purchase data periodically at a predetermined time interval, or may acquire the product purchase data in response to a user request.

[0046] The policy response data storage unit 107 stores policy response data. The policy response data is performance data that indicates whether or not a customer responded to a sales promotion policy such as an advertisement or an incoming call. The policy response data is stored in a policy response performance table, which will be described later.

[0047] The policy response data can be acquired, for example, from a marketing system that executes a sales promotion policy. The characteristic estimation device 10 may acquire the policy response data from the marketing system periodically at a predetermined time interval, or may acquire the policy response data from the marketing system in response to a user request.

[0048] The characteristic determination rule storage unit 108 stores characteristic determination rules. The characteristic determination rules are information representing rules for determining which of predetermined consumption behavior characteristics a target user corresponds to based on consumption behavior data estimated about the target user. The characteristic determination rules are determined in advance by a user of the consumption behavior characteristic estimation system 1. The characteristic determination rules are stored in a characteristic determination rule table, which will be described later.

[0049] The browsing history classification unit 111 identifies the category of the web page recorded in each web browsing history by matching the web browsing history with the site classification master.

[0050] The subject extraction unit 112 matches the web browsing history with the subject master, thereby associating the viewers of each web browsing history with the subjects of the market research, thereby extracting target users whose consumption behavior characteristics are to be estimated.

[0051] The result data acquisition unit 113 acquires consumption behavior result data related to the target user. The consumption behavior result data in this embodiment includes contact medium data, product purchase data, and policy response data.

[0052] The consumption behavior estimation unit 114 estimates consumption behavior data of the target user based on the web browsing history and consumption behavior performance data of the target user. The consumption behavior data in this embodiment includes purchase speed data indicating the purchase speed of the target user, and listening degree data indicating the listening degree of the target user.

[0053] The characteristic determination unit 115 determines the consumption behavior characteristic of the target user based on the consumption behavior data of the target user. The consumption behavior characteristic is determined according to characteristic determination rules.

[0054] <Processing procedure of the consumer behavior characteristic estimation system> Next, a consumption behavior characteristic estimating method executed by the consumption behavior characteristic estimating system 1 in this embodiment will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an example of a processing procedure of the consumption behavior characteristic estimating method in this embodiment.

[0055] In step S1, the user terminal 20 transmits a request signal requesting estimation of a consumption behavior characteristic to the characteristic estimation device 10 in response to an operation by a user of the consumption behavior characteristic estimation system 1. The characteristic estimation device 10 receives the request signal from the user terminal 20 and starts up the browsing history classification unit 111.

[0056] The browsing history classification unit 111 included in the characteristic estimation device 10 reads out the web browsing history from the web browsing history table stored in the web browsing history storage unit 102. Next, the browsing history classification unit 111 reads out the site classification information from the site classification master stored in the site classification master storage unit 101.

[0057] <Site Classification Master> The site classification master in this embodiment will be described with reference to Fig. 5. Fig. 5 is a conceptual diagram showing an example of the site classification master in this embodiment.

[0058] As shown in FIG. 5, the site classification master in this embodiment has, as data items, a URL (Uniform Resource Locator), major items, and medium items. The URL is information that represents the location of a web page. The major items are information that represent the category of the web page. The medium items are information that represent subcategories that are obtained by subdividing the major items. The site classification master illustrated in FIG. 5 subdivides categories into two levels, major items and medium items, but the number of category levels can be set arbitrarily as needed.

[0059] <Web browsing history table> The web browsing history table in this embodiment will be described with reference to Fig. 6. Fig. 6 is a conceptual diagram showing an example of the web browsing history table in this embodiment.

[0060] As shown in FIG. 6, the web browsing history table in this embodiment has data items such as history ID, cookie, access time (Time), URL, number of browsing times (Count), and source (Source). The history ID is identification information that identifies the browsing history. The cookie is identification information that is recorded in an information processing terminal used by a web browser. Therefore, the web browser can be identified by the cookie. The source is information that indicates the media from which the link that opened the URL was made.

[0061] Next, the browsing history classification unit 111 compares the URLs included in the web browsing history with the URLs included in the site classification information. This identifies the category of the web pages recorded in each web browsing history. The URLs may be compared by full-text match or by prefix match. The URLs may also be compared by complete domain match or by partial domain match.

[0062] Fig. 7 is a conceptual diagram showing an example of a web browsing history to which site classification information has been added. As shown in Fig. 7, in the web browsing history, each URL is assigned with a major item and a minor item of the site classification master. This identifies the category of the web page indicated by each URL in the web browsing history. For example, it can be seen that the web page indicated by the URL "http: / / abc.com / 456" is a web page that contains news about automobiles.

[0063] Returning to Fig. 4, in step S2, subject extraction unit 112 included in characteristic estimation device 10 reads out a web browsing history from a web browsing history table stored in web browsing history storage unit 102. Next, subject extraction unit 112 reads out subject information from the subject master stored in subject master storage unit 104.

[0064] <Subject Master> The subject master in this embodiment will be described with reference to Fig. 8. Fig. 8 is a conceptual diagram showing an example of the subject master in this embodiment.

[0065] As shown in Fig. 8, the subject master in this embodiment has data items such as a survey ID, a cookie, an RMID, a WT_FPC, and a customer ID. The survey ID is identification information that identifies market research results, and is an ID that is uniquely assigned to each subject of the market research. The customer ID is one of the customer IDs stored in the customer master. In other words, the subject master is associated with the customer master by the customer ID.

[0066] <Customer Master> The customer master in this embodiment will be described with reference to Fig. 9. Fig. 9 is a conceptual diagram showing an example of the customer master in this embodiment.

[0067] As shown in Fig. 9, the customer master in this embodiment has the following data items: customer ID, name, contact information (email address, etc.), and phase. The customer ID is identification information for identifying a customer. The phase is information that classifies the degree of interest of the customer in a product into a plurality of stages. The phase is determined, for example, based on the results of market research on the customer or the reaction to sales promotion measures, and is registered, for example, in a customer management system or the like.

[0068] The phases in this embodiment are five stages: "awareness-interest", "interest-concern", "interest-desire", "desire-action", and "action-sharing". The types of phases are not limited to these, and may be more subdivided into six or more stages, or more condensed into four or less stages.

[0069] Awareness is a state in which a customer is aware of a product. Note that a product is not limited to a good or service, but may be a product in a broad sense including a brand. Interest is a state in which a customer shows interest in a product. Interest is a state in which a customer shows interest in a product. Desire is a state in which a customer feels a desire to purchase the product. Action is a state in which a customer has taken action to purchase the product. Sharing is a state in which a customer has shared information about the product with others.

[0070] The subject extraction unit 112 compares the cookies included in the web browsing history with the cookies included in the subject information. The cookies are compared by full-text match. This associates each viewer of the web browsing history with the subject of the market research.

[0071] FIG. 10 is a conceptual diagram showing an example of a web browsing history associated with subject information. As shown in FIG. 10, each cookie in the web browsing history is associated with a survey ID and a customer ID from the subject master. This identifies the customer ID corresponding to each cookie. For example, it can be seen that a user to whom a cookie "a3fWa" is assigned is a customer identified by a customer ID "U0001."

[0072] The subject extraction unit 112 extracts a customer ID included in the subject information that can be associated with the web browsing history. Hereinafter, the extracted customer ID is treated as the customer ID of the target user. In other words, the target user is a user whose customer ID can be identified from among users who browsed the web of a company or the like that uses the consumption behavior characteristic estimation system 1.

[0073] Returning to Fig. 4, in step S3, the performance data acquisition unit 113 included in the characteristic estimation device 10 reads out contact medium data related to the target user from the contact medium table stored in the contact medium data storage unit 105. Next, the performance data acquisition unit 113 reads out product purchase data related to the target user from the product purchase performance table stored in the product purchase data storage unit 106. Next, the performance data acquisition unit 113 reads out policy response data related to the target user from the policy response performance table stored in the policy response data storage unit 107.

[0074] Then, the result data acquiring unit 113 associates the contact medium data, the product purchase data, and the policy response data for the same customer, thereby acquiring consumption behavior result data for the target user.

[0075] <Contact Media Table> The contact medium table in this embodiment will be described with reference to Fig. 11. Fig. 11 is a conceptual diagram showing an example of the contact medium table in this embodiment.

[0076] As shown in Fig. 11, the contact medium table in this embodiment has data items such as a survey ID and contact frequency. The contact frequency is information that indicates the contact frequency for each medium (television, the Internet, newspapers, magazines, etc.). The survey ID is one of the survey IDs stored in the subject master. In other words, the contact medium table is associated with the subject master by the survey ID.

[0077] <Product purchase record table> The product purchase record table in this embodiment will be described with reference to Fig. 12. Fig. 12 is a conceptual diagram showing an example of the product purchase record table in this embodiment.

[0078] 12, the product purchase history table in this embodiment has, as data items, the purchase date and time when the product (or service) was purchased, the customer ID, the purchased product, etc. The customer ID is one of the customer IDs stored in the customer master. In other words, the product purchase history table is associated with the customer master by the customer ID.

[0079] <Policy response performance table> The policy response results table in this embodiment will be described with reference to Fig. 13. Fig. 13 is a conceptual diagram showing an example of the policy response results table in this embodiment.

[0080] 13, the policy response record table in this embodiment has data items such as customer ID and whether or not there was a response for each phase. The customer ID is one of the customer IDs stored in the customer master. In other words, the policy response record table is associated with the customer master by the customer ID.

[0081] The phases are the same as those of the customer master, and are divided into five stages: "Awareness - Interest," "Interest - Concern," "Interest - Desire," "Desire - Action," and "Action - Sharing." In the policy response performance table, it is recorded whether or not the customer responded to the sales promotion policy in each phase.

[0082] Returning to Fig. 4, in step S4, the consumption behavior estimation unit 114 included in the characteristic estimation device 10 calculates a correct value of the purchasing velocity data and a correct value of the listening level data based on the web browsing history and the consumption behavior actual data related to the target user. The correct value of the purchasing velocity data and the correct value of the listening level data are calculated from the web browsing history and the consumption behavior actual data according to a predetermined rule.

[0083] Next, the consumer behavior estimation unit 114 assigns the correct value of the purchasing speed data and the correct value of the listening level data to the web browsing history and the consumer behavior performance data. This generates learning data in which the web browsing history and the consumer behavior performance data are explanatory variables and the purchasing speed data or the listening level data is an objective variable. The consumer behavior estimation unit 114 estimates the purchasing speed data and the listening level data for the target user using a machine learning model trained using the learning data.

[0084] Specifically, the consumption behavior estimation unit 114 estimates purchase speed data for the target user by performing multiple regression analysis on the learning data in which the correct answer value of the purchase speed data is assigned to the web browsing history and consumption behavior performance data. Also, the consumption behavior estimation unit 114 estimates listening degree data for the target user by performing multiple regression analysis on the learning data in which the correct answer value of the listening degree data is assigned to the web browsing history and consumption behavior performance data.

[0085] The multiple regression analysis is an example of a machine learning model, and other machine learning models may be used. For example, the purchase speed data and the listening interest data regarding the target user may be estimated by a decision tree or a neural network.

[0086] Fig. 14 is a conceptual diagram showing an example of purchase speed data and listening level data. As shown in Fig. 14, the purchase speed data is data showing the purchase speed of the target user for each phase. The purchase speed is an index showing the time it takes to purchase a product in the corresponding phase.

[0087] In this embodiment, the purchasing velocity is an index obtained by converting the time required from progressing to a particular phase until purchase into a numerical value between 0 and 1. The smaller the purchasing velocity value, the faster the purchasing velocity, and the larger the purchasing velocity value, the slower the purchasing velocity. Note that since a product may be purchased before progressing to a particular phase, the purchasing velocity may be a negative value. For example, if a product is purchased at the stage of awareness of the product, the purchasing velocity corresponding to the interest and subsequent phases will be a negative value.

[0088] As shown in Fig. 14, the listening level data is data indicating the listening level of the target user for each phase. The listening level is a truth value indicating the presence or absence of a response to the policy. The listening level data is the same data as the policy response data.

[0089] Returning to FIG. 4, in step S5, the characteristic determination unit 115 included in the characteristic estimation device 10 calculates a purchase velocity score from the purchase velocity data related to the target user. The purchase velocity score is calculated by multiple regression analysis of the purchase velocity data. Next, the characteristic determination unit 115 calculates a listening degree score from the listening degree data related to the target user. The listening degree score is calculated by multiple regression analysis of the listening degree data.

[0090] Fig. 15 is a conceptual diagram showing an example of a purchase speed score and a listening degree score. As shown in Fig. 15, the purchase speed score is an index representing the overall purchase speed of the target user regardless of the phase. Also, the listening degree score is an index representing the overall listening degree of the target user regardless of the phase.

[0091] Returning to Fig. 4, in step S6, the characteristic determination unit 115 included in the characteristic estimation device 10 reads out a characteristic determination rule from the characteristic determination rule table stored in the characteristic determination rule storage unit 108. Then, the characteristic determination unit 115 specifies a consumption behavior characteristic corresponding to a combination of a purchase speed score and a listening degree score, thereby determining the consumption behavior characteristic of the target user.

[0092] <Characteristics Rule Table> The characteristic determination rule table in this embodiment will be described with reference to Fig. 16. Fig. 16 is a conceptual diagram showing an example of the characteristic determination rule table in this embodiment.

[0093] 16, the characteristic determination rule table in this embodiment has consumption behavior characteristics, purchase speed scores, listening degree scores, etc. as data items. The purchase speed scores and listening degree scores are set within a score range, and are set so that a unique consumption behavior characteristic is determined for a certain combination of purchase speed scores and listening degree scores. In other words, the characteristic determination rule is a rule that associates a combination of purchase speed scores and listening degree scores with a consumption behavior characteristic.

[0094] The characteristic determination unit 115 outputs an estimation result of a consumption behavior characteristic for the target user. The characteristic estimation device 10 transmits the consumption behavior characteristic estimation result output by the characteristic determination unit 115 to the user terminal 20. The user terminal 20 receives the consumption behavior characteristic estimation result from the characteristic estimation device 10 and displays it on the display device 506 or the like.

[0095] Fig. 17 is a conceptual diagram showing an example of a consumption behavior characteristic estimation result. As shown in Fig. 17, the consumption behavior characteristic estimation result is information that lists consumption behavior characteristics estimated for each target user. The estimation result displayed by the user terminal 20 may be information obtained by processing the estimation result received from the characteristic estimation device 10. For example, the estimation result may be a list of target users estimated to have a consumption behavior characteristic specified by the user.

[0096] <Effects of the embodiment> The consumer behavior characteristic estimation system in this embodiment estimates purchase speed data and listening level data for a target user based on the user's web browsing history and the user's consumption behavior performance, and estimates the consumer behavior characteristics of the target user based on the purchase speed data and listening level data. Therefore, the consumer behavior characteristic estimation system in this embodiment can estimate the consumer behavior characteristics of the target user based on performance data that represents the consumer behavior of the target user.

[0097] The consumer behavior characteristic estimation system in this embodiment estimates purchase speed data and listening level data used to determine consumer behavior characteristics based on web browsing history and consumer behavior performance data. That is, the consumer behavior characteristic estimation system in this embodiment determines consumer behavior characteristics based on existing performance data. Therefore, there is no need to obtain new information about new target users. Therefore, the consumer behavior characteristic estimation system in this embodiment can estimate the consumer behavior characteristics of target users in real time.

[0098] For example, in the invention disclosed in Patent Document 1, it is necessary to obtain new survey results in order to estimate the characteristics of new users. Therefore, the invention disclosed in Patent Document 1 has a high inflow and outflow of unspecified users, and it is difficult to apply it to tasks that require real-time performance.
