Such information may be collected from companies that sell products and the like.

  “Calculation date and time” indicates the date and time when the comprehensive evaluation of the product or the like is calculated by the calculation unit 160.

  “Comprehensive evaluation” indicates comprehensive evaluation calculated by the calculation unit 160 based on evaluations by a plurality of subjects. The overall evaluation may be the same as the “evaluation” in the attribute database 150. For example, at least one of the score, the number of stars, and the total number of good / normal / bad, recommended button pressed, etc. including.

  FIG. 4 shows an example of a flow for calculating the comprehensive evaluation according to the present embodiment. In step 410, the input / output control unit 102 receives evaluation data indicating evaluation of a product or the like from the user terminal 20 and transmits it to the evaluation acquisition unit 120. The evaluation acquisition unit 120 acquires the evaluation of the product and the target identification information to be evaluated from the evaluation data. Then, the evaluation acquisition unit 120 transmits the acquired evaluation and target identification information and evaluation data to the purchase confirmation unit 130. At this point, since it is unknown whether the target person evaluated has purchased the evaluation target, the evaluation acquisition unit 120 acquires both the purchaser evaluation by the evaluation target purchaser and the non-purchase evaluation by the non-purchaser. Then, it may be transmitted to the purchase confirmation unit 130.

  In step 420, when the received evaluation data includes purchase confirmation information, the purchase confirmation unit 130 performs purchase confirmation based on the purchase confirmation information, and the received evaluation is either purchaser evaluation or non-purchaser evaluation. May be determined. For example, the purchase confirmation information may be confirmed based on a receipt image, a product image, a store image, or the like.

  As an example, the purchaser acquires an image of a receipt at the time of purchase of an evaluation target by the imaging function of the user terminal 20 (for example, a portable terminal), and transmits it to the apparatus 40 as evaluation data. The purchase confirmation unit 130 may confirm that the purchaser has purchased the evaluation target according to the confirmation result based on the receipt image in the evaluation data. Specifically, the purchase confirmation unit 130 performs image analysis on the receipt image, recognizes the product name, service name, store name, or identification code (for example, JAN code) in the image as the target identification information, and further the product You may recognize the purchase amount. Then, when the target identification information input by the target person included in the evaluation data is included in the target identification information recognized from the receipt image, the purchase confirmation unit 130 includes target identification information for identifying the evaluation target in the receipt image. A confirmation result indicating that it is included can be obtained. The purchase confirmation unit 130 may confirm that the purchaser has purchased the evaluation target on the condition that the confirmation result is obtained. Here, the purchase confirmation unit 130 recognizes the purchase date and time in the receipt image, and in the attribute database 150 via the attribute database connection unit 140, at the same purchase date and time as the recognized purchase date and time, with the same subject and the same evaluation target. If it is confirmed that the purchase amount is stored, it may be determined that the received evaluation is a non-purchaser evaluation. The purchase confirmation unit 130 may include target identification information such as a product name collected from a company or the like.

  Moreover, the purchase confirmation part 130 may recognize object identification information from a product image or a store image by image analysis, and may perform purchase confirmation similarly to a receipt image.

  In addition, when the received evaluation data does not include purchase confirmation information, the purchase confirmation unit 130 uses the target person identification information and the target identification information included in the evaluation data via the attribute database connection unit 140. Thus, the attribute database 150 may be searched. The purchase confirmation unit 130 may determine from the search result that the target person identification information and the target identification information are not associated in the attribute database 150 that the target person has not purchased the evaluation target. Further, the purchase confirmation unit 130 may transmit a purchase confirmation request for prompting the user to transmit purchase confirmation information to the device 40 via the input / output control unit 102 to the user terminal 20 of the target person. The purchase confirmation information may be received from the user terminal 20 separately from the evaluation data.

  After the purchase confirmation, the purchase confirmation unit 130 transmits the purchaser evaluation confirmed by the purchase confirmation information to the attribute database connection unit 140 together with the target person identification information, while acquiring the purchase amount of the evaluation target. It may be transmitted to the attribute database connection unit 140 via the unit 110. Further, the purchase confirmation unit 130 may also transmit the non-purchaser evaluation for which purchase confirmation could not be performed to the attribute database connection unit 140.

  In step 430, the attribute database connection unit 140 may store the evaluation, the purchase amount, and the target identification information in the attribute database 150 in association with the purchaser's target person identification information. When the evaluation target evaluation is already stored in the attribute database 150 in association with the target person identification information, the attribute database connection unit 140 receives the already stored evaluation from the purchase confirmation unit 130. (E.g., overwrite or addition / subtraction). Furthermore, the attribute database connection unit 140 may add the purchase amount of the evaluation target from the purchase amount acquisition unit 110 to the purchase amount of the evaluation target already stored.

  The attribute database connection unit 140 may also store the evaluation target non-purchaser evaluation and target identification information in the attribute database 150 in association with the target person identification information. In this case, the purchase amount to be evaluated in the attribute database 150 is not registered and remains 0.

  In step 440, the calculation unit 160 extracts purchase amounts of evaluation targets and evaluations of the evaluation targets stored in the attribute database 150 via the attribute database connection unit 140, and evaluates the overall evaluation targets. Calculate the rating.

  The calculation unit 160 may calculate a comprehensive evaluation periodically (for example, every day, every month, or every year) in response to receiving purchase information and / or in response to receiving evaluation data. For example, the calculation unit 160 receives the purchase information from the store terminal 30 when the input / output control unit 102 receives the purchase information in the attribute database 150 and increases the purchase amount and purchase amount after the purchase amount increases. A new comprehensive evaluation may be calculated and updated based on the purchaser evaluation before the increase. The calculation unit 160 may calculate a new comprehensive evaluation for the evaluation target of the evaluation data in response to the input / output control unit 102 receiving the evaluation data and storing the evaluation in the attribute database 150.

  The calculation unit 160 may extract the evaluation and purchase amount from the attribute database 150 based on at least one of the evaluation target period, the attribute of the target person, and the like via the attribute database connection unit 140. For example, for the evaluation target, the calculation unit 160 may extract the evaluation that the target person is male and the purchase amount from the attribute database 150 and calculate the comprehensive evaluation.

  The calculation unit 160 may calculate the overall evaluation of the evaluation target based on the evaluation and the purchase amount within a predetermined evaluation target period. For example, the calculation unit 160 extracts the purchase amount of the evaluation target whose purchase date / time is within the evaluation target period (for example, within half a year or within five years) from the current time from the attribute database 150 via the attribute database connection unit 140. Can do. In this case, the calculation unit 160 may use evaluation target periods with different lengths for different first evaluation objects and second evaluation objects. For example, the calculation unit 160 may use evaluation target periods having different lengths according to the evaluation target attributes. Specifically, the calculation unit 160 uses a shorter evaluation target period for evaluation objects having entertainment attributes such as music or games, and more for evaluation objects such as home appliances, durable consumer goods, or books. A long evaluation period may be used. The evaluation target period may be set in advance for each product or each type of product or the like by a company or the like that provides a service using the system 10.

  For the evaluation extracted from the attribute database 150, the calculation unit 160 causes the evaluation by the subject with a larger purchase amount to be reflected in the overall evaluation larger, and causes the evaluation by the subject with the smaller purchase amount to be reflected in the smaller overall evaluation. As such, it may be weighted. For example, the calculation unit 160 may perform weighting for each of a plurality of ranges of the purchase amount (for example, a range of purchase numbers 0 to 10, 11 to 20, 21 to 30, and so on). The calculation unit 160 may calculate a comprehensive evaluation that reflects the purchaser evaluation larger than the non-purchaser evaluation. For example, the evaluation of a person who cannot confirm that the purchase target has been purchased by the purchase confirmation unit 130 (non-purchaser evaluation) ) May not be reflected in the overall evaluation.

  When the purchase amount exceeds the upper limit purchase amount, the calculation unit 160 may reflect the purchaser evaluation in the overall evaluation with the same degree as when the purchase amount is the same as the upper limit purchase amount. The calculation unit 160 may include an upper limit purchase amount database that is preset for each product or each type of product or the like by a provider that provides a service using the system 10. The upper limit purchase amount may be a value that is x (x> 1) times the average of the purchase amounts of all the subjects for one evaluation target. Further, the upper limit purchase amount may be set according to at least one of the price to be evaluated and the attribute. For example, the upper limit purchase amount may be set larger for a cheaper evaluation object and smaller for a more expensive evaluation object. Further, the upper limit purchase amount may be set larger for foods such as sweets and smaller for music CDs and the like.

  The calculation unit 160 may largely reflect the evaluation by the specific target person in the comprehensive evaluation for the specific target person who is highly evaluated by other target persons. For example, in the service provided by the system 10 or other services, the calculation unit 160 makes a lot of evaluations (for example, “Like” or “referenced”) on posts (for example, word-of-mouth or reviews) about products and the like. The evaluation by a specific target person who has obtained “, etc.” may be largely reflected in the comprehensive evaluation.

  Here, in the attribute database 150, the evaluation target is a confectionery having a product name of “... chocolate”, and for the target persons A, B, C, D, the purchase amount of the evaluation target is 10, 30, 20 An example in which the calculation unit 160 calculates a comprehensive evaluation for the case where the number is 0, and the evaluation is 3, 5, 2, or 3 stars. The upper limit purchase amount of 20 sweets is set, and it is assumed that the target person A is the target person who has the highest evaluation from other target persons for the reviews on the service provided by the system 10. Therefore, the evaluation of the subject person B is reflected in the comprehensive evaluation as the upper limit purchase amount of 20, and the evaluation of the subject person A is greatly reflected by the comprehensive evaluation. Further, in this embodiment, the target person D whose purchase amount is 0 is not reflected in the comprehensive evaluation.

  The calculation unit 160 converts the purchase amount into a ratio, A: B: C = 1: 2: 2, and multiplies the ratio of the target person A by a coefficient 1.5 to obtain A: B: C = 1.5. : 2: 2 and the weighting coefficients are A = 1.5 / 5.5, B = 2 / 5.5, and C = 2 / 5.5. The calculation unit 160 can calculate the total evaluation star 3.36 by multiplying the corresponding evaluations by these weighting factors and adding them up.

  In addition, in the attribute database 150, the evaluation target is a food product with the product name “... Bread”, and for the target persons E, F, G, H, the purchase amount of the evaluation target is 5, 30, 10, Another example will be described in which the calculation unit 160 calculates a comprehensive evaluation when the number is 0 and the evaluation is a score of 35 points, 80 points, 90 points, or 20 points. For food, the upper limit purchase amount is set to twice the average, and in this example, the upper limit purchase amount is 22.5, and the weighting coefficient is 0.9, 6 to 10 in the purchase amount range of 0-5. The number is 1.0, 11-20 is 1.1, 21-30 is 1.2. The upper limit purchase amount may be a value calculated by multiplying the average by x (x> 1) for each product or each category of the product. Further, the upper limit purchase amount may be a value calculated based on purchase amount statistical information (for example, standard deviation value of purchase amount) for each product.

  The weighting factors for each subject are E = 0.9, F = 1.2, G = 1.0, and H = 0.9. The calculation unit 160 can calculate an overall evaluation score of 58.88 by multiplying the corresponding evaluation scores by these weighting factors and averaging them.

  The calculation unit 160 transmits the comprehensive evaluation and the calculation date calculated in this way to the product database connection unit 170 together with the target identification information.

  In step 450, the product etc. database connection unit 170 causes the product etc. database 180 to store the comprehensive evaluation and the calculation date and time in association with the target identification information. The product database connection unit 170 may store a comprehensive evaluation for each calculation date and time for the same evaluation object in the product database 180, or may overwrite the comprehensive evaluation with the latest calculation date and time.

  FIG. 5 shows an example of a flow for displaying the comprehensive evaluation according to the present embodiment. In step 510, the user interface 100 receives an evaluation display request for requesting display of comprehensive evaluation from the user terminal 20. The evaluation display request may include at least one condition among designation of target identification information from the target person, designation of the type of product, etc., and designation of attributes.

  In step 520, the display control unit 104 reads the comprehensive evaluation together with the target identification information to be evaluated from the product database 180 via the product database connection unit 170 in accordance with the conditions specified in the evaluation display request. For example, when specific target identification information is specified in the evaluation display request, the display control unit 104 determines the total of products corresponding to the target identification information from the product database 180 via the product database connection unit 170. Read evaluation. In addition, for example, when a type of a specific product is specified in the evaluation display request, the display control unit 104 selects a plurality of products included in the type from the product database 180 via the product database connection unit 170. Read the overall evaluation. Further, for example, when a specific attribute is specified in the evaluation display request, the display control unit 104 has one or more attributes having an attribute that matches the attribute from the product database 180 via the product database connection unit 170. Read the overall evaluation of the product. Specifically, when “male” which is an attribute is specified in the evaluation display request, the display control unit 104 acquires the product etc. attribute from the product database 180 via the product database connection unit 170. A comprehensive evaluation of one or more products that are “male” may be read out.

  In step 520, the display control unit 104 transmits the read data such as comprehensive evaluation to the user terminal 20 that transmitted the evaluation display request, and performs control to display the comprehensive evaluation on the display screen in association with the evaluation target. .

  The display control unit 104 may perform control to display the ranking of at least one of the types of specific products and the like and the history of changes in the comprehensive evaluation on the display screen of the user terminal 20. For example, in response to an evaluation display request designating men and sweets, the display control unit 104 displays the ranking of sweets whose purchase layer is male on the display screen of the user terminal 20 in order of overall evaluation.

The CPU 2000 operates based on programs stored in the ROM 2010 and the RAM 2020 and controls each unit. The graphic controller 2075 acquires image data generated by the CPU 2000 or the like on a frame buffer provided in the RAM 2020 and displays it on the display device 2080. Instead of this, the graphic controller 2075 may include a frame buffer for storing image data generated by the CPU 2000 or the like.

  The input / output controller 2084 connects the host controller 2082 to the communication interface 2030, the hard disk drive 2040, and the DVD drive 2060, which are relatively high-speed input / output devices. The communication interface 2030 communicates with other devices via a network by wire or wireless. The communication interface functions as hardware that performs communication. The hard disk drive 2040 stores programs and data used by the CPU 2000 in the computer 1900. The DVD drive 2060 reads a program or data from the DVD 2095 and provides it to the hard disk drive 2040 via the RAM 2020.

  The input / output controller 2084 is connected to the ROM 2010, the flash memory drive 2050, and the relatively low-speed input / output device of the input / output chip 2070. The ROM 2010 stores a boot program that the computer 1900 executes at startup and / or a program that depends on the hardware of the computer 1900. The flash memory drive 2050 reads a program or data from the flash memory 2090 and provides it to the hard disk drive 2040 via the RAM 2020. The input / output chip 2070 connects the flash memory drive 2050 to the input / output controller 2084 and inputs / outputs various input / output devices via, for example, a parallel port, a serial port, a keyboard port, a mouse port, and the like. Connect to controller 2084.

  A program provided to the hard disk drive 2040 via the RAM 2020 is stored in a recording medium such as a flash memory 2090, a DVD 2095, or an IC card and provided by a user. The program is read from the recording medium, installed in the hard disk drive 2040 in the computer 1900 via the RAM 2020, and executed by the CPU 2000. The information processing described in these programs is read by the computer 1900 and provides cooperation between the software and the various types of hardware resources. An apparatus or method may be configured by implementing information manipulation or processing in accordance with the use of computer 1900.

  As an example, when communication is performed between the computer 1900 and an external device or the like, the CPU 2000 executes a communication program loaded on the RAM 2020 and executes a communication interface based on the processing content described in the communication program. A communication process is instructed to 2030. Under the control of the CPU 2000, the communication interface 2030 reads transmission data stored in a transmission buffer area or the like provided on a storage device such as the RAM 2020, the hard disk drive 2040, the flash memory 2090, or the DVD 2095, and transmits it to the network. Alternatively, the reception data received from the network is written into a reception buffer area or the like provided on the storage device. As described above, the communication interface 2030 may transfer transmission / reception data to / from the storage device by a DMA (direct memory access) method. Instead, the CPU 2000 transfers the storage device or the communication interface 2030 as a transfer source. The transmission / reception data may be transferred by reading the data from the data and writing the data to the communication interface 2030 or the storage device of the transfer destination.

  Further, the CPU 2000 DMAs all or necessary portions of files or databases stored in an external storage device such as the hard disk drive 2040, the DVD drive 2060 (DVD 2095), the flash memory drive 2050 (flash memory 2090), or the like. The data is read into the RAM 2020 by transfer or the like, and various processes are performed on the data on the RAM 2020. Then, CPU 2000 writes the processed data back to the external storage device by DMA transfer or the like. In such processing, since the RAM 2020 can be regarded as temporarily holding the contents of the external storage device, in the present embodiment, the RAM 2020 and the external storage device are collectively referred to as a memory, a storage unit, or a storage device.

  Various types of information such as various programs, data, tables, and databases in the present embodiment are stored on such a storage device and are subjected to information processing. Note that the CPU 2000 can also store a part of the RAM 2020 in the cache memory and perform reading and writing on the cache memory.
