The process of changing to a recommendation engine and determining whether the result of a predetermined calculation is the same is executed.

Also in this case, if the calculation result is the same, it means that the same product or the like as the product or the like that the user who has already searched does not want is searched. Be changed.

Then, the third determination unit included in the determination unit 357 executes a process of determining whether or not the result of the predetermined calculation based on the recommendation engine is a product or the like desired by the user. In this case, when the result of the calculation is presented to the user, a means process for automatically determining based on the user's behavior such as browsing time and scroll that can be implicitly acquired, and a button for switching the recommendation engine to the user are presented. There is a means for explicitly switching the recommendation engine, such as "Yes".

[4] Specific Example of Data Registered in Database Next, the details of each database constituting the recording unit 340 included in the information providing server device 30 will be specifically described with reference to FIGS. 4 to 6 described above. explain.

(Recommendation engine information DB)
The recommendation engine information DB 341 is a DB that stores, as data, information about a recommendation engine that the data processing unit 350 uses to acquire information about products and the like for the user. In the recommendation engine information DB 341 shown in FIG. 4,
(1) Recommendation engine ID for identifying each recommendation engine,
(2) An algorithm configured as a predetermined arithmetic expression in which a procedure for deriving the recommendation information is formulated, and (3) a parameter which is a constituent element of the algorithm and is used in the arithmetic expression,
Are registered in association with each other.

In the recommendation engine information DB 341 illustrated in FIG. 4, for example, the recommendation engine ID “E0001”, one of the algorithms “algorithm 1”, and one of the parameters used in the algorithm 1 “parameter 1”. And are registered in association with each other.

(Product information DB)
The product etc. information DB 342 is a DB in which information about products or services to be recommended to users is registered. In the product etc. information DB 342 of this embodiment, only the information about the product is registered. In the product etc. information DB 342 illustrated in FIG. 5,
(1) Product ID for identifying each product,
(2) A specific product name specified by the product ID, and (3) product detailed information, which is information about detailed contents of the product, are registered in association with each other.

For example, in the product etc. information DB 342 illustrated in FIG. 5, a product ID “C00001”, a specific product name “product 1” of the product, and product detailed information “○○” indicating information regarding the detailed content of the product. "...○○○" is registered in association with each other. As the product detailed information, for example, a maker of the product, a general name of the product, a material of the product, a production place of the product, a capacity of the product, an effect of the product, and the like are specifically registered.

(User information DB)
The user information DB 343 is a DB for storing each piece of data regarding basic information of a user who uses the information providing system 1 of the present embodiment. In the user information DB 343, as shown in FIG.
(1) User ID for identifying each user,
(2) Basic information of each user specified by each user ID, and (3) Recommendation engine ID for specifying the recommendation engine selected by each user
Are associated and registered.

In the case illustrated in FIG. 6, in the user information DB 343, for example, the user ID of the user identified by “U00001” and the “user basic information 1” that is the basic information of the user identified by the user ID. , And a recommendation engine ID “E0003” for specifying the recommendation engine selected by the user is registered in association with each other. The basic information about the user identified by each user ID can be, for example, the name of the user, the gender of the user, the date of birth of the user, the address of the user, the occupation of the user, and the like.

[5] Specific Content of Process Next, the specific content of the process executed by the data processing unit 350 will be described.

In the information providing server device 30 of the present embodiment, the initialization process of the recommendation engine is executed at the initial stage of operating the system and the stage of newly adding the recommendation engine. That is, when using the recommendation engine, a process is performed to define what information the user should input to use the recommendation engine. Specifically, a process of extracting an arbitrary item from the product detailed information, configuring the extracted item as a vector, and storing this vector as a parameter is executed. For example, the price of the product and its weight are taken out, and the parameters are constructed based on the price and weight of the product. After this processing is executed, the processing described below can be performed.

In the data processing unit 350, when the data processing unit 350 includes the above-described configuration units 351 to 356, when providing the user with information about products or the like desired by the user as recommendation information, the parameter change and the recommendation engine The changes are performed sequentially.

That is, in the data processing unit 350, detailed information about a product is sequentially read from the product information DB 342 on the basis of a search word such as a name of a product or the like input by the user, and numerical information constituting detailed information of the product is read. When a predetermined arithmetic processing is executed by an arithmetic expression having parameters based on the numerical information input by the user and the result is transmitted to the communication terminal device 10 of the user, the information about the transmitted product is displayed by the user. If the information is different from the information regarding the desired product, the parameters forming the recommendation engine are changed.

The process of changing the parameter is executed as follows.

First, the search result is transmitted from the information providing server device 30 to the communication terminal device 10 of the user. When the transmitted information about the product etc. is different from the product desired by the user, the operation unit 160 is operated by the user to reject the product, and a signal to that effect is sent from the communication terminal device 10 to the information providing server. It is transmitted to the device 30.

The data processing unit 350 of the information providing server device 30 changes the parameter in response to receiving the signal of the rejection. After the parameter is changed, the data processing unit 350 executes the search for the product again. In this case, if the result of the search process using the old parameter before changing the parameter and the result of the search process using the changed parameter are the same for the information about the searched product, etc. The search result is not transmitted to the communication terminal device 10. In this case, the data processing unit 350 executes processing for changing to another parameter.

Changing the parameter means, for example, if the parameter before the change is configured based on the weight and price of the apple as the product, the parameter is configured based on the size of the apple as the product and the sugar content contained in the apple. This is a concept that includes not only changing the numerical value itself, such as setting a parameter to be set, but also changing the content of the numerical value or the like that constitutes the parameter.

Then, when the result of the search process is different from the result of the old parameter before the change and the result of the parameter after the change, the information providing server device 30 causes the communication terminal device 10 to search for the searched product at that time. Send information about the information again.

When these processes are repeatedly executed and the user can provide the information regarding the desired product, the user executes the process for confirming the information regarding the product, and the signal is the data processing unit 350. Be transmitted to. Examples of the process for confirming the information about the product include a process for purchasing the product, a process for showing that the evaluation for the product is good, and a process for obtaining detailed information about the product. The processing etc. can be raised.

Examples of the process for purchasing the product include a process used in a known product purchase system, for example, an operation of touching a display portion for display displayed on the display unit 135 for purchase. You can The processing for indicating that the evaluation of the product is good includes, for example, an operation of touching the display portion of “Like” displayed on the display unit 135.

Further, as a process for acquiring detailed information about the product, for example, a configuration is made such that a display portion “detailed information” is displayed on the display unit 135, and when the display portion is touched, The information storage unit in which the detailed information of the product is registered can be browsed from the screen showing the product. In this case, the product etc. information DB 342 is provided with a storage unit in which detailed information of each product etc. is registered, and the user browses the information registered in the storage unit via the communication terminal device 10. ..

On the other hand, for one recommendation engine, the parameters constituting the recommendation engine are sequentially changed, and as a result of searching for products and the like using all the parameters, it is not possible to provide information about the product and the like desired by the user. If so, the recommendation engine is changed.

The recommendation engine can be changed by configuring the recommendation engine to be automatically changed when the user cannot search for a desired product etc. by the recommendation engine before the change, or the recommendation engine is changed by the user. The operation to change is executed via the operation unit 160 of the communication terminal device 10, and is configured to be changed when the user's intention is transmitted to the information providing server device 30 via the communication terminal device 10. It can be configured as needed.

The changed recommendation engine is executed by randomly acquiring recommendation engine information that is not currently used from the recommendation engine information registered in the recommendation engine information DB 341.

After the recommendation engine is changed, the search for products or the like is executed in the same manner as the above-described processing by sequentially changing the parameters forming the recommendation engine.

Then, a recommendation engine and parameters suitable for the user are registered in the recommendation engine information DB 341 in association with the user. Specifically, it is registered together with the user ID.

As the recommendation engine in the present embodiment, for example, a self-organizing map is applied. The self-organizing map is one of artificial intelligence algorithms, and is established by calculations such as (1) determination of winning neurons, (2) update of coupling coefficient, and (3) neighborhood function.

First, determine the vertical and horizontal size of the map and the tropology. Then the map is initialized with random numbers. Then, among all the units in the input and output layers, the most similar unit mc is searched for, and that unit is made the winner. That is, the winner is determined using the following (Equation 1).

Then, the weight vectors m _i of the winning unit and its neighboring units are updated. At that time, the following (formula 2) is used.

The above process is performed for all inputs.

The principle of the process performed by the recommendation engine when the user searches for an apple will be specifically described with reference to FIGS. 7 and 8. In the recommendation engine, the weight and price of apples are used as numerical information, and the parameter is formed by using the weight and price of apples. FIG. 7 is an explanatory diagram for explaining specific data in each DB of one example of searching for products using the recommendation engine, and FIG. 8 visually shows a self-organizing map. Is a graph for explaining.

In this example, as shown in FIG. 7A, user information about one user who searches for products and the like using a recommendation engine is shown. Specifically, the user ID is specified by "U00001", the name which is one of the basic information is "Taro Yamada", and the recommendation engine ID is specified by "E00001".

Then, as shown in FIG. 7B, in this recommendation engine, the components of the data vector are composed of the weight of the product, the price, and the product ID. In the example shown in FIG. 7B, the data vector is, for example, “49g, 195 yen, C00012”, “197g, 105 yen, C00021”, “197g, 195 yen, C00022”, “193g, 233 yen, C00023”. , "228 g, 182 yen, C00032" and the like.

As shown in FIG. 7C, the specific data of the product specified by each product ID is, as shown in FIG. 7C, the product specified by the product ID “C00012” has a product name of Amaou (strawberry) and a weight. Is 549g and the price is 195 yen. Hereinafter, it is assumed that the products identified by product IDs “C00021”, “C00022”, “C00023”, and “C00032” also have the data as shown in the figure.

When a self-organizing map is applied to a product having such data and a user searches for a desired product, it can be expressed as shown in FIG. In FIG. 8, the horizontal axis represents the weight (g) of the product, and the vertical axis represents the price (yen). The line connecting the circles, triangles, and diamonds shown in FIG. 8 represents one parameter.

It is assumed that the user inputs an apple weighing 200 grams and having a price of 200 yen. Numerical information input by the user is shown as a hexagon at a coordinate point located substantially at the center in FIG. Since this recommendation engine uses a self-organizing map, it selects a product indicated by a circle existing at the position closest to the coordinate point indicated by the hexagon. That is, the product having the smallest value calculated by (Equation 1) is selected. In the case of the data shown in FIG. 7, "tsugaru (red apple)" identified by the product ID "C00022" is selected.

Then, by (Equation 2), the unit of the product near the product represented by the circle is updated. In the example shown in FIG. 8, the product represented by the diamond, which is connected to a circle by a line, is updated. In the case of the data shown in FIG. 7, the product ID is "Amaou (strawberry)" identified by "C00012", the product ID is "Hokuto (red apple)" identified by "C00021", and the product ID is "C00023". "Mutsu (green apple)" specified by the item "Otsu (green apple)" specified by the product ID "C00032" are updated.

When this is quantitatively shown, the selected m _c is {197g, 195 yen, C00022}, and the neighborhood is {49g, 195 yen, C00012}, {197g, 105 yen, C00021}, {193g, 233 yen, C00023} and {228g, 1825 yen, C00032}.

In the example of this case, the reason why "tsugaru (red apple)" is selected by executing the self-organizing process is that the Tsugaru (red apple) is
(A) Bigger than Amaou (strawberry),
(B) Higher than Hokuto (red apple),
(C) It's easier than mutsu (green apple),
This is because it is smaller than (D) Ourin (green apple).

The case where the search is performed using the parameters configured based on the weight and the price of the product has been described above as an example. When the user presents a product retrieved using a parameter configured based on the weight and price of the product, if the desired product does not exist in the presented products, this information providing system In 1, the parameters are changed.

For example, the parameter before the change is configured based on the weight and the price of the apple as described above, but the parameter after the change is configured by the size of the apple and the sugar content of the apple, for example. Parameters are used. That is, changing a parameter is a concept that includes both changing the numerical value itself that constitutes the parameter or changing the content itself of the element that constitutes the parameter.

Also, the case where the recommendation engine is a self-organizing map has been described. However, when the self-organizing map is used as the recommendation engine and the product or the like desired by the user cannot be retrieved, the information providing system 1 according to the embodiment changes the recommendation engine. For example, modified recommendation engines may include algorithms such as neural gas, k-means, and multilayer perceptron.

Neural gas is one of unsupervised learning algorithms, a network used for vector quantization, and an algorithm very similar to a self-organizing map. Vector quantization means approximating a set of many input vectors with a relatively small number of units (reference vectors).

The k-means method is a non-hierarchical clustering algorithm unlike the self-organizing map. This is a method of classifying a given number of clusters into k using the average of clusters.

Specifically, the k-means method is generally implemented by the following flow. The number of data is n and the number of clusters is k. First, a cluster is randomly assigned to each data x _i . Next, the center V _{j of} each cluster is calculated based on the assigned data. Then, the distance between each x _i and each V _j is calculated, and x _i is reassigned to the cluster having the closest center. Then, when the allocation of all the clusters of x _i does not change in the above processing, or when the change amount falls below a predetermined threshold value set in advance, it is determined that the convergence has occurred, and the processing ends.

Multilayer perceptron is one of machine learning algorithms. This multilayer perceptron is based on the concept of formal neuron, and consists of three parts: an input layer, an intermediate layer, and an output layer. The input layer and the intermediate layer are randomly connected. A signal is given to the input layer from the outside, and the intermediate layer reacts based on the information from the input layer. The output layer is based on the idea that the answers of the middle layer are weighted, the majority decision is made, and the answer is given. In the multi-layer perceptron, the perceptron is made into a multi-layer and is learned by the error backpropagation learning method, so that the problem that cannot be linearly separated is solved.

[6] Operation of Information Providing System of Present Embodiment [6.1] Operation of Overall Information Providing System Next, with reference to FIGS. 9 to 12, the information providing system of the present embodiment selects a recommendation engine suitable for a user. The operation of providing the user with information such as products will be described. 9 is a flowchart showing the operation of the information providing system 1, FIG. 10 is a flowchart showing the operation of obtaining an output, FIG. 11 is a flowchart showing the operation of the parameter changing process, and FIG. 6 is a flowchart showing an operation of a recommendation engine changing process.

In this operation, it is assumed that the recommendation engine initialization process has already been executed. Also, it is assumed that necessary data has already been registered in the recommendation engine information DB 341, the product etc. information DB 342, and the user information DB 343.

First, the information providing server device 30 determines whether or not the communication control unit 320 has received from the communication terminal device 10 a signal indicating that the user has performed a login operation (step S101).

Next, when the confirmation of the login of the user is obtained, the data processing unit 350 acquires the first recommended engine information to be applied to the user from the recommended engine information DB 341 (step S102). In this step, when the user uses the information providing system 1 for the first time or when searching for a product or the like of a completely different type from the one used so far, the data processing unit 350 causes the recommendation engine information DB 341. The first recommendation engine information is randomly selected and read. On the other hand, when the user is already using the information providing system 1 and searches for a product or the like similar to the product or the like previously searched, the data processing unit 350 has previously used the data. The recommended engine information is read from the recommended engine information DB 341.

Next, the user obtains a keyword such as a product that the user wants to be provided with information or digitized numerical information (step S103). That is, the keyword information of the product or the like is input to the communication terminal device 10 through the operation of the operation unit 160 by the user. The communication terminal device 10 transmits the keyword information to the information providing server 30, and the information providing server device 30 receives the keyword information via the communication control unit 320.

Next, when the information input by the user is keyword information, the input information digitizing unit 353 changes the keyword information and the information acquired from the product etc. information DB 342 into numerical information (step S104). In this case, the numerical information acquired by the data processing unit 350 is information in which the characteristics of the product such as “weight” and “price” of the product are digitized.

Next, the data processing unit 350 searches for products and the like using the read recommendation engine and the parameters forming the recommendation engine (step S105). At that time, the DB management unit 351 sequentially reads the information regarding the products registered in the product etc. information DB 342 from the product etc. information DB 342, and compares the read information with the numerical information to determine whether or not it is suitable as recommended information. Is making a decision.

Next, after performing the search for the product etc., an appropriate output process is executed for the output (step S200). Details of the process for obtaining this output will be described with reference to FIG.

As shown in FIG. 10, in the process of searching for a product or the like and obtaining an output, first, parameters are set in the algorithm that constitutes the recommendation engine (step S201). A plurality of parameters are prepared for each algorithm that constitutes each recommendation engine, and in step S201, the first parameter randomly selected is set in the algorithm.

Next, detailed product information is acquired based on the numerical information (step S202). Specifically, the numerical information acquisition unit 352 that constitutes the data processing unit 350 handles a parameter from the product detailed information in the information about the product etc. registered in the product etc. information DB 342 in cooperation with the DB management unit 351. Get the numerical information that is possible. In the example described with reference to FIGS. 7 and 8, information regarding the weight and price of the product is acquired from the product detailed information.

Then, the arithmetic operation is executed by a predetermined arithmetic expression which is composed of numerical information and parameters and which constitutes an algorithm that constitutes the recommendation engine, and the result of the arithmetic is output (step S203). In the recommendation engine, as described above, the self-organizing map is applied to search for products and the like, and the output result is information of products and the like closest to the numerical information input by the user, and the vicinity of the information. This is information such as products.

In the process of obtaining the output, the processes of steps S201 to S203 are executed.

The process after outputting the result will be described with reference to FIG. 9 again.

Next, the transmission unit 355 cooperates with the communication control unit 320, transmits the output result to the user's communication terminal device 10, and causes the display unit 135 of the communication terminal device 10 to display the result (step S106). The information providing server device 30 displays, for example, only one piece of information on a product or the like closest to the numerical information input by the user on the display unit 135 of the communication terminal device 10, or a plurality of products close to the numerical information. Etc. are displayed side by side in order from the closest one and executed.

Then, a process of determining whether or not to change the parameter is executed (step S107).

If the product or the like displayed on the display unit 135 is desired or close to the desired product, a process for confirming the product or the like is performed by the user via the communication terminal device 10. Then, the result is transmitted to the information providing server device 30. In the information providing server device 30 that has received the signal to execute the processing for confirmation, the recommended information confirmation unit 356 included in the data processing unit 350 determines information about the product or the like (step S109).

As an operation for determining a product etc. by the user, as described above, for example, as an evaluation for the product etc., an automatic evaluation means based on a browsing time or a scroll operation, or an evaluation of “like” And an explicit means for performing an operation for purchasing the product or the like.

On the other hand, when the product or the like displayed on the display unit 135 is different from the product or the like desired by the user, the product or the like is rejected through the operation of the operation unit 160. When the rejected process is performed, a signal to that effect is transmitted from the communication terminal device 10 to the information providing server device 30. Then, the parameter changing unit included in the changing unit 354 executes the parameter changing process (step S300).

Details of the parameter changing process will be described with reference to FIG.

First, the changing unit 354 executes a process of selecting a parameter that is not currently selected (step S301). As described above, since the recommendation engine prepares a plurality of parameters, the changing unit 354 excludes the currently selected parameter from the algorithm and acquires the unselected parameter.

Next, the data processing unit 350 uses the newly selected parameter and acquires the product detailed information based on the numerical information in a form suitable for the parameter (step S302). Note that the processing executed in step S302 is the same as that in step S202 already described, so description of the processing content is omitted here.

Next, the data processing unit 350 executes arithmetic operations by a predetermined arithmetic expression that is composed of numerical information and parameters and that constitutes an algorithm that constitutes the recommendation engine, and outputs the arithmetic result (step S303). Note that the process executed in step S303 is the same as step S203 already described, and thus the description of the process content is omitted here.

Next, the first determination unit included in the determination unit 357 executes a determination process of whether or not the output result is the same as the output result when the process is performed using the old parameter before changing the parameter. (Step 304).

If the output results are the same, the currently selected parameter is automatically discarded, the process returns to step S301, and a new parameter is selected again. On the other hand, when the output result is different, the changing unit 354 determines the content of the algorithm by the content of the parameter, and cooperates with the DB management unit 351 to search the current product etc. using the information providing server device 30. The content of the recommended engine information DB 341 is updated with the value of the selected parameter in association with the user ID of the user.

If the result output by changing the parameters is the product or the like desired by the user, the data processing unit 350 executes processing for confirming the product or the like (step S109).

In the parameter changing process (step S300), when the search process is executed with all the parameters and the product etc. suitable for the user cannot be searched, the data process is performed as shown in the flowchart shown in FIG. The unit 350 executes a determination process as to whether or not to change the recommendation engine (step S108).

In the parameter changing process (step S300), if the product or the like suitable for the user can be searched when the search is performed by using the finally selected parameter, the recommendation engine is not changed. , And proceeds to the next step S109.

On the other hand, in the parameter changing process (step S300), if a suitable product or the like cannot be retrieved even if all the parameters are used, the changing unit 354 executes the process of changing the recommendation engine. ..

The details of the process of changing the recommendation engine (step S400) will be described with reference to FIG.

First, the changing unit 354 newly selects a recommendation engine that is not currently selected (step S401). At that time, the changing unit 354 cooperates with the DB management unit 351 to access the recommendation engine information DB 341 and read out the recommendation engine information registered in the recommendation engine information DB 341. The recommendation engine information is randomly selected.

Next, the data processing unit 350 uses the newly selected recommendation engine to acquire the detailed product information based on the numerical information using the first parameter (step S402). Note that this is executed in step S402. Since the content of the processing to be performed is the same as that in step S202 described above, the description of the processing content is omitted here.

Next, the data processing unit 350 executes a predetermined calculation process based on the product detailed information and outputs the result (step S403). Since the processing executed in step S403 is the same as that in step S203 described above, the description of the processing content is omitted here.

Next, the second determination unit included in the determination unit 357 executes a determination process of whether or not the output content is the same as that of the old recommendation engine before changing the recommendation engine (step S404).

As a result of the determination by the second determination unit, if the outputs are the same, the parameter is changed (step S405). After changing the parameters, the detailed product information is obtained again based on the numerical information (step S402), and the above steps are executed again.

On the other hand, as a result of the determination by the second determination unit, if the output contents are different, the parameter information is updated with the changed value in association with the user information (step S406). Since this processing is the same as the processing content of step S305, detailed description thereof will be omitted.

When the products and the like suitable for the user are searched by executing the above processes, the product and the like executed by the user for the communication terminal device 10 are determined as in step S109 of the flowchart shown in FIG. Based on this processing, the recommendation information determination unit 356 determines information regarding the product or the like.

Next, the processing for determining whether or not to end the processing is executed (step 110). The data processing unit 350 sends a signal indicating that the user searches for another product or the like based on the signal from the communication terminal device 10. When the is received, the numerical information input by the user is again acquired (step S102), and each processing described above is executed. If not, log out and end the operation.

Although not particularly shown in FIG. 9, before the operation is completed, information about the recommendation engine suitable for the user is registered in the recommendation engine information DB 341 together with the user ID of the user, and the recommendation engine suitable for the user is displayed. The user who uses the recommendation engine is associated.

[7] Modification Example [7.1] Modification Example 1
