Description

  Embodiments described herein relate generally to an information processing apparatus and an information processing method for estimating a user's funnel structure on the Internet or the like.

  The user has a predetermined intent regarding conversion of a predetermined advertisement distributed on the Web, and belongs to various hierarchies (cognition, interest / interest, examination, immediately before, etc.) based on the intent. The distribution of users in each hierarchy has a funnel structure. From the advertiser's perspective, it is important to correctly evaluate the value of the delivered advertisement and to optimize the composition of the advertisement, such as the content and quantity of the advertisement, and it is necessary to know the funnel structure as the premise. .

  Conventionally, however, an analog method such as a questionnaire is used to visualize the funnel structure. Analog methods such as questionnaires are expensive and it is difficult to obtain a sufficient amount of data. In addition, objective information is not always obtained, for example, a questionnaire includes an answer based on misperception or an answer that makes the person look good.

  Therefore, a technique for estimating the funnel structure from an access log on the Internet is required.

Special table 2014-512613 gazette

  In order to solve the above problems, an information processing apparatus and an information processing method for estimating a funnel structure are provided.

  According to the embodiment, the information processing apparatus that estimates the funnel structure includes a conversion user log extraction unit, a path extraction unit, a setting unit, a transition probability calculation unit, an unconverted user log extraction unit, and a hierarchy estimation unit. And a structure estimation unit. The conversion user log extraction unit extracts a conversion user log of a user who has completed the conversion. The route extraction unit extracts, based on the conversion user log, a category viewed by the user who has completed the conversion until the conversion and a transition route of the category. The setting unit sets a browsing ratio of the category for each hierarchy of the funnel structure based on the category extracted by the route extracting unit and the transition route of the category. The transition probability calculation unit calculates a transition probability that a user belonging to each layer of the funnel structure transitions to each layer based on the category extracted by the route extraction unit and the transition route of the category. The unconverted user log extraction unit extracts an unconverted user log of a user who has not completed the conversion. A hierarchy estimation part estimates the hierarchy of the user who has not completed the conversion based on the unconverted user log and the browsing ratio of the category. The structure estimation unit estimates the funnel structure based on the estimation result of the hierarchy estimation unit.

  According to the embodiment, the information processing apparatus can model the funnel hierarchy (generate a hierarchy table and a transition probability table) based on the Web browsing log of the user who has completed the conversion. Further, the information processing apparatus can estimate the funnel structure of the user who has not completed the conversion by modeling the funnel structure.

  That is, the information processing apparatus can estimate the number of users for each level and the transfer probability between levels. Therefore, the above estimation makes it possible to estimate the volume for each tier and which tier will expand or contract in the future.

  Further, the information processing apparatus can estimate the funnel structure of the user who has viewed the advertisement and the funnel structure of the user who has not viewed the advertisement. Therefore, the information processing apparatus can present the advertising effect as a difference between both funnel structures. For example, if the number of users at a specific level of the funnel structure of the user who viewed the advertisement increases and the level immediately above (for example, “recognition” if the specific level is “interest / interest”) decreases, Is estimated to have an effect of transitioning the user from the immediately higher hierarchy to the specific hierarchy.

  Further, the information processing apparatus estimates both funnel structures after the advertisement distribution. As a result, it is possible to cancel a change caused by another element (for example, a television CM) with respect to the difference between both funnel structures. Therefore, the effect of the advertisement can be grasped more clearly.

FIG. 7 shows a transition example of the funnel structure according to the embodiment. FIG. 8 is a flowchart illustrating an operation example of the information processing apparatus according to the embodiment. FIG. 9 is a flowchart illustrating an operation example of the information processing apparatus according to the embodiment.

Hereinafter, embodiments will be described with reference to the drawings.
First, the funnel structure will be described.
FIG. 1 shows a configuration example of the funnel structure 1.

The funnel structure 1 indicates the number of users for each hierarchy related to conversion of a predetermined advertisement.
A conversion is the final result of an advertisement run by an advertiser. For example, the conversion is purchase of a predetermined article, request for data, or browsing a predetermined site. The content of the conversion is not limited to a specific configuration.

  As shown in FIG. 1, the funnel structure 1 includes layers 2 to 6 and the like. Levels 2 to 6 are “recognition”, “interest / interest”, “examination”, “immediately before”, and “conversion”, respectively. In the example illustrated in FIG. 1, the larger the hierarchy area, the greater the number of users. The funnel structure 1 may not include “conversion” as a hierarchy.

  “Recognition” is a layer that recognizes matters related to the results of conversion. For example, when the conversion is a purchase of a predetermined product, “recognition” is a hierarchy that recognizes the product as a matter related to the result. Further, when the conversion is browsing of an event notification site, “recognition” is a hierarchy that recognizes the event or the like as a matter related to the result.

  “Interest / interest” is a level in which the person is interested in matters related to the results. In other words, “interest / interest” is a level that has a certain interest / interest in matters related to the results, although it is not just about considering conversion.

  “Review” is a hierarchy in which conversion is being considered. In other words, “examination” is a hierarchy in which it is considered to perform conversion beyond mere interest.

  “Just before” is a hierarchy immediately before conversion. That is, “immediately before” is a hierarchy in which the consideration of conversion is finished and it is determined to perform conversion.

  “Conversion” is a hierarchy in which a conversion is completed.

  In the example shown in FIG. 1, the number of users decreases as the hierarchy increases from “recognition”, “interest / interest”, “examination”, “immediately before”, and “conversion”.

  Note that the funnel structure may further include other layers. Further, the funnel structure may not include the above-described hierarchy. Also, the number of funnel structure layers is not limited to a specific number. The configuration of the funnel structure is not limited to a specific configuration.

Next, the information processing apparatus according to the embodiment will be described.
FIG. 2 is a block diagram illustrating a configuration example of the information processing apparatus 10.
In the configuration example illustrated in FIG. 2, the information processing apparatus 10 includes a CPU 11, a ROM 12, a RAM 13, an NVM 14, a communication unit 15, an operation unit 16, a display unit 17, and the like as basic configurations. These units are connected to each other via a data bus. Note that the information processing apparatus 10 may include a configuration as necessary in addition to the configuration illustrated in FIG. 2 or may exclude a specific configuration.

  The CPU 11 has a function of controlling the overall operation of the information processing apparatus 10. The CPU 11 may include an internal cache and various interfaces. The CPU 11 implements various processes by executing programs stored in advance in the internal memory, the ROM 12 or the NVM 14.

  Note that some of the various functions realized by the CPU 11 executing the program may be realized by a hardware circuit. In this case, the CPU 11 controls functions executed by the hardware circuit.

  The ROM 12 is a non-volatile memory in which a control program and control data are stored in advance. The control program and control data stored in the ROM 12 are incorporated in advance according to the specifications of the information processing apparatus 10. The ROM 12 stores, for example, a program (for example, BIOS) that controls the circuit board of the information processing apparatus 10.

  The RAM 13 is a volatile memory. The RAM 13 temporarily stores data being processed by the CPU 11. The RAM 13 stores various application programs based on instructions from the CPU 11. The RAM 13 may store data necessary for executing the application program, an execution result of the application program, and the like.

  The NVM 14 is a nonvolatile memory capable of writing and rewriting data. The NVM 14 is configured by, for example, a hard disk, SSD, EEPROM (registered trademark), flash memory, or the like. The NVM 14 stores a control program, an application, and various data according to the operational use of the information processing apparatus 10.

  Further, the NVM 14 includes a storage area 14a for storing a Web browsing log that is a record of a user browsing the site. For example, the web browsing log includes a user, a browsed site (for example, a URL), a browsed date and time, and the like.

  The communication unit 15 is an interface for transmitting / receiving data to / from an external device through the communication network 5. The communication unit 15 is an interface that supports LAN connection, for example.

  Various operation instructions are input to the operation unit 16 by the operator of the information processing apparatus 10. The operation unit 16 transmits an operation instruction signal input to the operator to the CPU 11. The operation unit 16 is, for example, a keyboard, a numeric keypad, and a touch panel.

  The display unit 17 is a display device that displays various information under the control of the CPU 11. The display unit 17 is, for example, a liquid crystal monitor. When the operation unit 16 is configured with a touch panel or the like, the display unit 17 may be formed integrally with the operation unit 16.

Next, functions realized by the CPU 11 will be described.
First, the CPU 11 has a function (conversion user log extraction unit) that extracts a web browsing log (conversion user log) of a user who has completed conversion.
The CPU 11 extracts, from the storage area 14a, a Web browsing log of the user who has completed the conversion and a Web browsing log which has been obtained for a predetermined period from the date and time when the conversion has been completed. For example, the CPU 11 extracts a web browsing log 30 days, 60 days, or 90 days before the conversion is completed. CPU11 may determine the period which speaks based on conversion. For example, the CPU 11 may set a relatively long period for a conversion (for example, purchase of a high-priced product) that seems to take time to make a decision. In addition, for example, the CPU 11 may set a relatively short period for conversion that can be determined in a short period (for example, purchase of a low-priced product). The method for determining the period during which the CPU 11 extracts the Web browsing log is not limited to a specific method.

The CPU 11 has a function (route extraction unit) that identifies a category of a site browsed by a user who has completed conversion and a route for changing the category based on the extracted web browsing log.
The CPU 11 sets a category for the extracted Web browsing log site.
Categories are set based on site characteristics. The site category may be manually set for each site in advance. The site category may be automatically set by the CPU 11 according to a predetermined algorithm. The method of setting the category for the site is not limited to a specific method.

  Next, the CPU 11 extracts what category the user who completed the conversion has changed to reach the conversion. That is, the CPU 11 extracts a category that the user who has completed the conversion characteristically browses, and extracts a transition path of the category.

  For example, the CPU 11 extracts a category that the user who has completed the conversion particularly browses. Further, the CPU 11 calculates the transition probability between the categories. That is, the CPU 11 calculates the probability of browsing a site in another category after browsing a site in a certain category.

  The CPU 11 sets a path as a transition route between the categories based on the transition probability between the categories. For example, the CPU 11 may set a path between categories whose transition probability is higher than a predetermined threshold. In addition, the CPU 11 may set paths of different thicknesses (that is, paths having different intensities) between the categories according to the transition probability.

  For example, CPU11 may extract the category which the user who completed conversion browses using a Bayesian network, and may extract the transition path | route of the category which leads to conversion.

3 and 4 show examples of category transitions of users who have completed conversion.
Here, it is assumed that the CPU 11 has extracted categories 21 to 24. The categories 21 to 24 are “ordinary media”, “life change”, “beauty health”, and “related product information”, respectively.

  “Usual media” is a site that users use on a daily basis. For example, “usually used media” includes a search engine or a portal site.

  “Life change” is a site that is browsed when a user's life changes or is about to change. For example, “life change” includes a site related to moving and the like.

  “Beauty and health” is a site related to beauty or health. For example, “beauty health” includes sites related to cosmetics or health foods.

  “Related product information” is a site that is strongly related to conversion. For example, when the conversion is purchase of a product, the “related product information” is a critique site for the product or an introduction site for a product similar to the product.

  3 and 4, arrows indicate paths. That is, the arrow indicates that the user transitions from the category at the start point of the arrow to the category at the end point of the arrow.

  As shown in FIGS. 3 and 4, one of the transition paths that the user leads to conversion is a path that sequentially follows category 21 (“usually used media”), category 24 (“related product information”), and “conversion”. is there. Further, another one of the transition paths leading to the conversion by the user is category 21 (“usually used media”), category 23 (“beauty health”), category 24 (“related product information”), and “conversion” in this order. It is a route to follow. In addition, another transition path through which the user leads to conversion is a path that sequentially follows category 21 (“usually used media”), category 23 (“beauty health”), and “conversion”. In addition, other transition paths leading to conversion by the user are category 21 (“usually used media”), category 22 (“life change”), category 23 (“beauty health”), category 24 (“related products”). Information ”) and“ conversion ”. In addition, another transition path leading to the conversion by the user follows category 21 (“usually used media”), category 22 (“life change”), category 23 (“beauty health”), and “conversion” in this order. It is a route.

  Note that the number of categories extracted by the CPU 11 is not limited to a specific number. The category configuration extracted by the CPU 11 is not limited to a specific configuration. Further, the route extracted by the CPU 11 is not limited to a specific configuration.

  Further, the CPU 11 has a function (setting unit) for setting the browsing ratio of the extracted category for each hierarchy of the funnel structure. In other words, the CPU 11 sets the ratio of categories viewed by the user for each level of the funnel structure. For example, the CPU 11 sets the browsing ratio of each category with respect to all browsing of the extracted categories. For example, the CPU 11 generates a table (hierarchy table) that associates the hierarchy of the funnel structure with the browsing ratio of the category in the hierarchy.

  FIG. 5 shows a configuration example of a hierarchy table in which a funnel structure hierarchy and a category browsing ratio in the hierarchy are associated with each other.

  As shown in FIG. 5, the hierarchical table shows that users belonging to “cognition” indicate “usually used media”, “life change”, “beauty health”, and “related product information” by 80%, 10%, 7%, and Indicates browsing at a rate of 3%. In addition, the hierarchical table indicates that users belonging to “interest / interest” have “daily media”, “life change”, “beauty health” and “related product information” of 40%, 30%, 15% and 15%, respectively. Indicates browsing by ratio. In addition, the hierarchy table shows that users belonging to “Review” have “Personal media”, “Life change”, “Beauty and health”, and “Related product information” ratios of 10%, 20%, 60%, and 20%, respectively. Indicates browsing. In addition, the hierarchy table shows that users belonging to “immediately before” have a ratio of 5%, 10%, 50% and 35% for “daily use media”, “life change”, “beauty health” and “related product information”, respectively. Indicates browsing.

  Note that the ratio of each category set by the CPU 11 for each layer is not limited to a specific value. That is, the configuration of the hierarchy table set by the CPU 11 is not limited to a specific configuration.

  In addition, the CPU 11 has a function (transition probability calculation unit) that calculates a probability that a user belonging to each layer moves to each layer after a predetermined period based on a category and a transition path (transition probability) between the categories. That is, the CPU 11 calculates the transfer probability between tiers. For example, the CPU 11 generates a table (transition probability table) in which a hierarchy having a funnel structure is associated with a probability that a user in the hierarchy moves to each hierarchy after a predetermined period. Note that the transition probability table also includes the probability that the user stays in the hierarchy.

  FIG. 6 shows a configuration example of a transition probability table in which a hierarchy having a funnel structure is associated with a probability that a user in the hierarchy moves to each hierarchy after a predetermined period.

  As shown in FIG. 6, the transition probability table indicates that the users belonging to “recognition” are 80% each for “recognition”, “interest / interest”, “review”, “immediately”, and “conversion”. %, 3%, 15% and 0% probability of transfer. In addition, the transition probability table indicates that users belonging to “interest / interest” are 81%, 5%, 14%, and 0% for “interest / interest”, “examination”, “immediately”, and “conversion”, respectively, after a predetermined period. It indicates that it will move with probability of. Further, the transition probability table indicates that users belonging to “consideration” move to “consideration”, “immediately before”, and “conversion” after a predetermined period with a probability of 79%, 21%, and 0%, respectively. The transition probability table indicates that users belonging to “immediately before” move to “immediately” and “conversion” after a predetermined period with a probability of 87% and 13%, respectively.

  The probability that the CPU 11 is calculated for each hierarchy is not limited to a specific value. That is, the configuration of the transition probability table calculated by the CPU 11 is not limited to a specific configuration.

For example, the CPU 11 generates a hierarchy table and a transition probability table as follows.
The CPU 11 assumes the number of layers until “conversion” and the probability of transferring from each layer to the next layer. According to the assumption, the CPU 11 continuously evaluates to which hierarchy a certain user belongs and the probability of transition to the next hierarchy, and generates a hierarchy table and a transition probability table.

For example, the CPU 11 generates a hierarchy table and a transition probability table according to a hidden Markov model or the like.
The method for generating the hierarchy table and the transition probability table is not limited to a specific method.

The CPU 11 has a function (unconverted user log extraction unit) that extracts a Web browsing log (unconverted user log) of a user who has not completed conversion.
The CPU 11 extracts a web browsing log of a user who has not completed conversion from the storage area 14a. Note that the CPU 11 may extract a Web browsing log whose browsing date is within a predetermined period from the Web browsing log of a user who has not completed conversion.

  Further, the CPU 11 has a function (hierarchy estimation unit) that estimates the hierarchy of each user who has not completed conversion from the Web browsing log and hierarchy table of the user who has not completed conversion.

CPU11 estimates a hierarchy for every user based on the extracted web browsing log. For example, the CPU 11 extracts a web browsing log of a site included in a category indicated by the hierarchy table from a certain user's web browsing log. The CPU 11 calculates the browsing ratio of each category of the user based on the extracted Web browsing log. The CPU 11 refers to the hierarchy table and compares the browsing ratio of each category of the user with the browsing ratio of each category indicated by the hierarchy table. The CPU 11 estimates the hierarchy that most closely matches the browsing ratio of each category of the user as the hierarchy to which the user belongs.
CPU11 performs said operation | movement for every user, and estimates the hierarchy of each user.

  Further, the CPU 11 has a function (structure estimation unit) for estimating the funnel structure from each user's hierarchy. For example, the CPU 11 counts the number of users for each hierarchy, and estimates the number of users belonging to each hierarchy as a funnel structure. Further, for example, the CPU 11 may estimate the funnel structure at a rate for each layer. The CPU 11 may add “conversion”, which is a hierarchy of users who have completed the conversion, to the funnel structure.

  Moreover, CPU11 has a function which estimates the funnel structure which the user who browsed the predetermined | prescribed advertisement comprises, and the funnel structure which the user who is not browsing the said advertisement comprises. Here, it is assumed that the advertiser has distributed a predetermined advertisement on a predetermined Web. FIG. 7 shows a configuration example of the funnel structure 1a of the user who has viewed the advertisement and the funnel structure 1b of the user who has not viewed the advertisement.

  The CPU 11 extracts, from the storage area 14a, a web browsing log (browsing user log) of a user who has not completed conversion and browsed the advertisement (browsing user log extraction unit). For example, the CPU 11 extracts a user having a web browsing log indicating that the advertisement has been browsed, and extracts the web browsing log of the user.

  CPU11 estimates the hierarchy of each user who browsed the said advertisement from the extracted Web browsing log and hierarchy table (browsing user hierarchy estimation part). CPU11 estimates the funnel structure 1a of the user who browsed the said advertisement based on an estimation result (browsing user structure estimation part). The CPU 11 may add, to the funnel structure 1a, the level of the user who has viewed the advertisement and completed the conversion as the “conversion” level.

  Moreover, CPU11 extracts the web browsing log (non-browsing user log) of the user who has not completed conversion and has not browsed the advertisement from the storage area 14a (non-browsing user log extraction unit). For example, the CPU 11 extracts a user having a Web browsing log indicating that the advertisement has been browsed, and extracts a Web browsing log other than the user.

  CPU11 estimates the hierarchy of each user who is not browsing the said advertisement from the web browsing log and hierarchy table of the extracted user (non-browsing user hierarchy estimation part). CPU11 estimates the funnel structure 1b of the user who is not browsing the said advertisement based on an estimation result (non-browsing user structure estimation part). The CPU 11 may add the level of the user who has not viewed the advertisement and completed the conversion as the “conversion” level to the funnel structure 1b.

  With the above operation, as shown in FIG. 7, after the advertisement is distributed, the CPU 11 can estimate the funnel structure 1a of the user who has viewed the advertisement and the funnel structure 1b of the user who has not viewed the advertisement. In addition, CPU11 may classify | categorize a user for every frequency | count of browsing an advertisement, and may estimate the funnel structure for every browsing frequency.

Next, an operation example of the information processing apparatus 10 will be described.
First, an operation example in which the information processing apparatus 10 estimates the funnel structure will be described.
FIG. 8 is a flowchart for explaining an operation example in which the CPU 11 of the information processing apparatus 10 estimates the funnel structure.

  First, the CPU 11 extracts the Web browsing log of the user who has completed the conversion over a predetermined period from the storage area 14a (S11). When the Web browsing log of the user who has completed the conversion is extracted, the CPU 11 extracts a category and a transition path between categories based on the extracted Web browsing log (S12).

  When the categories and transition paths between the categories are extracted, the CPU 11 generates a hierarchy table based on the categories and the transition paths between the categories (S13). When the hierarchy table is generated, the CPU 11 generates a transition probability table based on categories, transition paths between categories, and the like (S14).

  When the transition probability table is generated, the CPU 11 extracts the Web browsing log of the user who has not completed the conversion (S15). When the Web browsing log of the user who has not completed the conversion is extracted, the CPU 11 estimates the hierarchy of each user who has not completed the conversion based on the extracted Web browsing log and the hierarchy table (S16).

  If the hierarchy of each user who has not completed conversion is estimated, CPU11 will estimate a funnel structure based on an estimation result (S17). When the funnel structure is estimated, the CPU 11 ends the operation.

  Next, an operation example in which the information processing apparatus 10 estimates the funnel structure of the user who has viewed the advertisement and the funnel structure of the user who has not viewed the advertisement will be described.

Here, it is assumed that the CPU 11 has finished generating the hierarchy table.

  First, the CPU 11 extracts, from the storage area 14a, a Web browsing log of a user who has not completed conversion and browsed an advertisement (S21). When the Web browsing log is extracted, the CPU 11 estimates the hierarchy of each user who viewed the advertisement based on the hierarchy table (S22).

  When the hierarchy of each user who has viewed the advertisement is estimated, the CPU 11 estimates the funnel structure of the user who has viewed the advertisement based on the estimation result (S23). If the funnel structure of the user who has viewed the advertisement is estimated, the CPU 11 extracts, from the storage area 14a, the Web browsing log of the user who has not completed the conversion and has not viewed the advertisement (S24).

  When the Web browsing log is extracted, the CPU 11 estimates the hierarchy of each user who is not browsing advertisements based on the hierarchy table (S25). If the hierarchy of each user who is not browsing advertisements is estimated, CPU11 will estimate the funnel structure of the user who is not browsing advertisements (S26).

  When the funnel structure of the user who is not browsing the advertisement is estimated, the CPU 11 ends the operation.

  Note that the CPU 11 may acquire a web browsing log from an external device. Further, the CPU 11 may display data indicating the number of users in each layer on the display unit 17 as a funnel structure. Further, the CPU 11 may transmit data indicating the funnel structure to the external device through the communication unit 15 or the like.
