Further, each embodiment can be appropriately combined within a range that does not contradict the processing contents. Also, in each of the following embodiments, the same parts are denoted by the same reference numerals, and overlapping descriptions are omitted.

[1. Example of information processing]
First, an example of calculation processing according to the embodiment will be described with reference to FIG. FIG. 1 is a diagram illustrating an example of information processing according to an embodiment. As shown in FIG. 1, an information processing system 1 according to the embodiment includes an information processing device 100 and a server 200, which are connected via a communication network N. As shown in FIG. In the information processing system 1, a plurality of information processing apparatuses 100 and servers 200 may be connected to the communication network N, respectively.

The information processing device 100 is an information processing terminal used by a user. The information processing device 100 is, for example, a smart phone, a tablet terminal, or the like. The information processing apparatus 100 may be a desktop PC (Personal Computer), a notebook PC, a mobile phone, a PDA (Personal Digital Assistant), a wearable device, or the like. The information processing apparatus 100 uses services such as a search engine provided by the server 200 in accordance with user operations.

The server 200 is a device such as a computer that provides services such as a search engine to the information processing device 100 .

The information processing apparatus 100 receives input of characters from the user and predicts a search word desired by the user from the received character string. The information processing apparatus 100 displays the search result obtained as a result of searching based on the search word in the region of the conventional suggestion display column in which the predicted character string is displayed as a suggestion. That is, the information processing apparatus 100 displays on the display screen 160 the search results obtained based on the predicted search word along with the character string received from the user. FIG. 1 shows an example in which the information processing apparatus 100 displays the search result below the character string received from the user. Hereinafter, the search results displayed on the information processing apparatus 100 show the search results displayed in the area of the suggestion display field where the predicted character string was conventionally displayed as a suggestion along with the character string received from the user. and

The information processing apparatus 100 starts displaying the search results when the input of characters is received from the user. The information processing apparatus 100 evaluates whether or not the displayed search result has been accepted by the user, based on the keystrokes that are the period from when the character input is received from the user until when the next character input is received. A case where the displayed search result is accepted by the user means a case where the search result desired by the user is obtained and the user is satisfied with the search result. The fact that the user is satisfied with the search result and that the search result has been accepted by the user can be rephrased as the user's recognition of the search result. When the keystroke is long, the information processing apparatus 100 determines that the user is looking at the search result for the search word predicted from the character string input at that time. The graph on the right side of FIG. 1 shows the relationship between the number of characters input to the information processing apparatus 100 and keystrokes, that is, time. If the number of keystrokes is greater than or equal to a specified threshold, the information processing apparatus 100 determines that the user is viewing the search results and that the displayed search results have been accepted by the user. On the other hand, if the number of keystrokes is less than the specified threshold, the information processing apparatus 100 determines that the displayed search results are not accepted by the user, assuming that the user has not seen the search results.

In the example of FIG. 1, the information processing apparatus 100 predicts "weather in Tokyo" as a search word desired by the user at the stage of accepting the input of the character string "Tokyo" from the user. The information processing apparatus 100 displays the search results obtained by using the search word "weather in Tokyo" together with the character string "Tokyo". In the example of FIG. 1, the information processing apparatus 100 displays information that the current weather is fine, the maximum temperature is 30° C., and the minimum temperature is 20° C., as the search result for “weather in Tokyo” in the example of FIG. When the user desires weather information for Tokyo, the information processing apparatus 100 determines that the number of keystrokes is greater than or equal to a specified threshold value, that is, the time required for the user to view the search results is longer, and the displayed search results are accepted by the user. evaluated as being

[2. Configuration of Information Processing Device]
Next, the configuration of the information processing apparatus 100 according to the embodiment will be described using FIG. FIG. 2 is a diagram illustrating a configuration example of the information processing apparatus 100 according to the embodiment. As shown in FIG. 2 , information processing apparatus 100 includes communication section 110 , storage section 120 , control section 130 , display section 140 and input section 150 .

(Regarding communication unit 110)
The communication unit 110 is realized by, for example, a NIC (Network Interface Card) or the like. The communication unit 110 is connected to the communication network N by wire or wirelessly, and transmits and receives information to and from the server 200 via the communication network N.

(Regarding storage unit 120)
The storage unit 120 is realized by, for example, a semiconductor memory device such as a RAM (Random Access Memory) or flash memory, or a storage device such as a hard disk or an optical disk. As shown in FIG. 2 , the storage section 120 has a threshold storage section 121 and an evaluation result storage section 122 .

(Regarding the threshold storage unit 121)
The threshold storage unit 121 stores threshold information for evaluating whether or not the displayed search result has been accepted by the user. Here, FIG. 3 shows an example of the threshold storage unit 121 according to the embodiment. FIG. 3 is a diagram illustrating an example of the threshold storage unit 121 according to the embodiment. In the example shown in FIG. 3, the threshold storage unit 121 has items such as "average keystroke" and "threshold".

"Average keystroke" indicates the average value of character input intervals when the search result is not accepted by the user. "Threshold" indicates a period for evaluating that the displayed search results have been accepted by the user. If the user accepts the search results, it is assumed that the time between entering the next character, ie, the keystrokes, increases for the user to view or read the search results. Therefore, the threshold value is n times the average keystroke. Note that n>1. Thereby, the information processing apparatus 100 can distinguish between when the user is viewing the search results and when not. The information processing apparatus 100 evaluates that the search result has been accepted by the user when the user is viewing the search result. Since the user's character input speed differs from user to user, the threshold will differ from user to user. Accordingly, the information processing apparatus 100 can make the threshold for users with long average keystrokes longer than the threshold for users with short average keystrokes. Note that the value of n may be changed according to the average keystroke length.

As will be described later, the evaluation unit 134 calculates the average keystrokes and the threshold, and stores them in the threshold storage unit 121 .

(Evaluation result storage unit 122)
The evaluation result storage unit 122 stores information regarding evaluation results as to whether or not the displayed search results have been accepted by the user. Here, FIG. 4 shows an example of the evaluation result storage unit 122 according to the embodiment. FIG. 4 is a diagram illustrating an example of the evaluation result storage unit 122 according to the embodiment. In the example shown in FIG. 4, the evaluation result storage unit 122 has items such as "search result" and "evaluation value" for each predicted search keyword.

“Search result” identifies the search result displayed on the information processing apparatus 100 . For example, a URL (Uniform Resource Locator) is used to identify the search result, but it is not limited to this. The "evaluation value" is the user's evaluation result for the "search result". For example, the possible range of evaluation values is defined, the lower half of the possible range is the evaluation value representing search results that are not accepted by the user, and the upper half of the possible range is the evaluation representing search results that are accepted by the user. value.

In the example of FIG. 4, when the search word is "XXXXXX", the evaluation value of the search result "B1" is "C1" and the evaluation value of the search result "B2" is "C2". .

As will be described later, the evaluation unit 134 determines evaluation values and stores them in the evaluation result storage unit 122 .

(Regarding the control unit 130)
The control unit 130 is a controller, and for example, various programs (information processing programs) stored in a storage device inside the information processing apparatus 100 are controlled by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. example) is implemented by executing the RAM as a work area. Also, the control unit 130 is, for example, a controller, and is implemented by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

As shown in FIG. 2, the control unit 130 includes a reception unit 131, a search unit 132, a display control unit 133, and an evaluation unit 134, and realizes or executes information processing functions and actions described below. do. Note that the internal configuration of the control unit 130 is not limited to the configuration shown in FIG. 2, and may be another configuration as long as it performs the information processing described later. Moreover, the connection relationship between the processing units of the control unit 130 is not limited to the connection relationship shown in FIG. 2, and may be another connection relationship.

(Regarding the reception unit 131)
Accepting unit 131 accepts characters input by the user via input unit 150 . Accepting unit 131 also accepts processing for deleting characters from the user via input unit 150 .

(Regarding the search unit 132)
The search unit 132 predicts a search word desired by the user from the character string received by the reception unit 131, that is, the current character string input by the user. The search unit 132 performs a search based on the predicted search word and obtains search results. Similarly, when a character is deleted in the reception unit 131, the search unit 132 predicts a search word desired by the user from the character string at the time when the character is deleted. The search unit 132 performs a search based on the predicted search word and obtains search results. Note that, if the evaluation result corresponding to the predicted search word is stored in the evaluation result storage unit 122, the search unit 132 refers to the information stored in the evaluation result storage unit 122, and searches for search results with high evaluation values. may be preferentially obtained.

(Regarding the display control unit 133)
The display control unit 133 displays the current character string received by the receiving unit 131 on the display screen 160 of the display unit 140, and displays the search result obtained by the searching unit 132 on the display screen 160 of the display unit 140. .

(Regarding the evaluation unit 134)
The evaluation unit 134 evaluates the search results according to the period until the number of characters received by the reception unit 131 changes, which is the period during which the search results are displayed on the display screen 160 of the display unit 140 by the display control unit 133. Evaluate whether it was accepted by users. The case where the number of characters changes is the case where the number of characters increases due to the input of characters by the user, or the number of characters decreases due to the deletion of characters by the user. The evaluation unit 134 evaluates that the search result has been accepted by the user when the period during which the search result is displayed exceeds the threshold stored in the threshold storage unit 121 . The evaluation unit 134 calculates the average keystrokes so that the thresholds shown in FIG. 3 can be used during the period when search results acceptable to the user cannot be displayed. Also, the evaluation unit 134 calculates the threshold by multiplying the average keystroke by n. The evaluation unit 134 stores the calculated average keystroke and threshold in the threshold storage unit 121 . The evaluation unit 134 will change the threshold according to the speed at which the user inputs characters. Further, when the evaluation unit 134 evaluates the search result, the evaluation unit 134 determines an evaluation value of the search result according to the evaluation result, and stores the evaluation value in the evaluation result storage unit 122 . For example, the evaluation unit 134 determines the evaluation value so that the evaluation value of the search result that is displayed and accepted by the user while the number of characters input by the user is small with respect to the number of characters of the search word is high.

(Regarding the display unit 140 and the input unit 150)
The display unit 140 is a display device for displaying various information. For example, the display unit 140 is realized by a liquid crystal display or the like. The input unit 150 is an input device that receives various operations from the user. Since the information processing apparatus 100 according to the embodiment employs a touch panel, the display unit 140 and the input unit 150 are integrated.

[3. Processing procedure]
Next, a procedure of processing by the information processing apparatus 100 according to the embodiment will be described with reference to FIG. FIG. 5 is a flow chart showing a processing procedure according to the embodiment.

As shown in FIG. 5, the information processing apparatus 100 receives input of characters from the user (step S1).

The information processing apparatus 100 predicts a search word desired by the user from characters or character strings input by the user (step S2).

The information processing device 100 performs a search based on the predicted search word (step S3). The information processing apparatus 100 acquires search results for the predicted search word.

The information processing apparatus 100 displays the current character string input by the user on the display screen, and displays the search result on the display screen (step S4).

The information processing apparatus 100 evaluates whether or not the search result displayed on the display screen has been accepted by the user (step S5). Specifically, the information processing apparatus 100 determines whether or not the search result has been accepted by the user according to the period until the number of accepted characters changes and the period during which the search result is displayed on the display screen 160. Evaluate. The information processing apparatus 100 evaluates that the search result has been accepted by the user when the period during which the search result is displayed on the display screen 160 exceeds the threshold.

The information processing apparatus 100 repeats the processing procedure from step S1 to step S5 each time the user inputs the next character or the user deletes the character.

[4. Modification]
The information processing apparatus 100 described above may be embodied in various forms other than the above embodiment. Therefore, other embodiments of the information processing apparatus 100 will be described below.

[4-1. Change the threshold according to the user attribute]
In the above embodiment, the threshold used for evaluating search results is calculated from the character input speed of the user. However, the information processing apparatus 100 may change the threshold according to the attributes of the user. This point will be described with reference to FIG. FIG. 6 is a diagram showing an example of the threshold storage unit 121 according to the first modified example. The example of FIG. 6 indicates that the threshold is "E1" when the user attribute is "D1", and the threshold is "E2" when the user attribute is "D2". It is assumed that the contents of the threshold storage unit 121 shown in FIG. 6 are preset in the information processing apparatus 100 .

Regarding user attributes, for example, there is a method of classifying users according to age, such as young people and old people. It is conceivable that older users read characters slower than younger users. Therefore, in the information processing apparatus 100, the threshold for the elderly users is made longer than the threshold for the young users according to the attributes of the users. Information processing apparatus 100 may use registered information when information such as the date of birth is registered in information processing apparatus 100 as information on attributes of a user being used, or may use a service that the user uses. If the login information set at the time of registration includes information such as date of birth and age, such information may be used.

In addition, although the method of classifying user attributes by age has been described, this is an example and the present invention is not limited to this. For example, user attributes may be classified by gender, occupation, address, etc. according to the content of the displayed search results.

As described above, in the information processing apparatus 100, the evaluation unit 134 changes the threshold to be used according to the attribute of the user. Accordingly, the information processing apparatus 100 can use different thresholds depending on the user who uses the information processing apparatus 100, and can flexibly evaluate whether or not the search result is accepted.

[4-2. Change the threshold according to the content of the search results]
In the above embodiment, the threshold used for evaluating search results is calculated from the character input speed of the user. However, the information processing apparatus 100 may change the threshold according to the type of content of the search results to be displayed. This point will be described with reference to FIG. FIG. 7 is a diagram showing an example of the threshold storage unit 121 according to the second modification. In the example of FIG. 7, the threshold is "G1" when the type of content to be displayed is "F1", and the threshold is "G2" when the type of content is "F2". It is assumed that the contents of the threshold storage unit 121 shown in FIG. 7 are preset in the information processing apparatus 100 .

The displayed search results shown in FIG. 1 are weather information, and the symbol elements are large, so the user does not need much time to confirm the contents. On the other hand, when the displayed search results indicate the meaning of a certain word, it takes time for the user to confirm the contents in comparison with the weather information. Therefore, in the information processing apparatus 100, the threshold for content that requires a lot of time to confirm the content is set longer than the threshold for content that requires less time to confirm the content. As for the threshold, a preset fixed value may be used, or it may be updated according to the usage status of the user.

As described above, in the information processing apparatus 100, the evaluation unit 134 changes the threshold according to the type of content of the displayed search results. Accordingly, the information processing apparatus 100 can use different thresholds depending on the content to be displayed, and can flexibly evaluate whether or not the search result has been accepted.

[4-3. Change the threshold according to the amount of information in the test results]
In the example of FIG. 1, the information processing apparatus 100 displays only current weather information as Tokyo weather information, but displays weather forecast information for several days from tomorrow, for example, for one week. It is also possible to In this case, since the amount of information in the displayed search results increases, it takes longer for the user to read all the displayed search results than in the example of FIG. Also, when the displayed search results indicate the meaning of a certain word, it is assumed that the amount of information of the displayed meaning will differ depending on the target word. Therefore, in the information processing apparatus 100, the threshold is changed according to the information amount of the search results to be displayed. The information processing apparatus 100 changes the threshold to be used, for example, in proportion to the number of characters in the displayed search results.

As described above, in the information processing apparatus 100, the evaluation unit 134 changes the threshold according to the information amount of the displayed search results. Thereby, the information processing apparatus 100 can use different thresholds according to the amount of information to be displayed, and can flexibly evaluate whether or not the search result has been accepted.

[4-4. Change the threshold according to the number of inspection results]
In the example of FIG. 1, the information processing apparatus 100 predicts the search word "Tokyo weather" for the character string "Tokyo". It is also possible to display search results, ie display multiple search results. For example, the information processing apparatus 100 predicts a plurality of search words such as "weather Tokyo" and "weather Osaka" at the stage of receiving the input of the character string "tenki" from the user, and predicts weather information for Tokyo and weather information for Osaka. Both of the two search results for weather information may be displayed. In this case, as in the case of the amount of information in the search results described above, it takes longer for the user to read all the displayed search results than in the example of FIG. Therefore, in the information processing apparatus 100, the threshold is changed according to the number of search results to be displayed. The information processing apparatus 100 changes the threshold to be used, for example, in proportion to the number of search results to be displayed.

Thus, in the information processing apparatus 100, the evaluation unit 134 changes the threshold according to the number of displayed search results. Accordingly, the information processing apparatus 100 can use different thresholds according to the number of displayed search results, and can flexibly evaluate whether or not the search results have been accepted.

[4-5. Evaluate when the number of characters is the largest]
In the above-described embodiment, the information processing apparatus 100 evaluates in real time whether or not the search result has been accepted, but it may be evaluated after the fact. The information processing apparatus 100 can acquire information on the relationship between the number of characters and keystrokes, as shown in the graph on the right side of FIG. 1, while the user is inputting characters. For example, the information processing apparatus 100 evaluates whether or not the search result was accepted by the user during the period in which the search result was displayed when the number of characters was the largest. In this case, the information processing apparatus 100 repeats the processing from step S1 to step S4 in the flowchart shown in FIG. 5, and performs the processing of step S5 only once at the end when the number of characters is determined.

Thus, in the information processing apparatus 100, the evaluation unit 134 evaluates whether or not the search result was accepted by the user during the period in which the search result was displayed when the number of characters received by the reception unit 131 was the largest. . Thereby, the information processing apparatus 100 can reduce the processing load compared to the case of evaluating whether or not the search result is accepted by the user each time the number of characters changes.

[4-6. Evaluate when the keystroke is the longest]
In the above-described embodiment, the information processing apparatus 100 evaluates in real time whether or not the search result has been accepted, but it may be evaluated after the fact. The information processing apparatus 100 can acquire information on the relationship between the number of characters and keystrokes, as shown in the graph on the right side of FIG. 1, while the user is inputting characters. The information processing apparatus 100 evaluates whether or not the search result is accepted by the user, for example, during the period in which the search result is displayed when the keystroke is the longest. In this case, the information processing apparatus 100 repeats the processing from step S1 to step S4 in the flowchart shown in FIG. 5, and performs the processing of step S5 only once at the end when the number of characters is determined.

As described above, in the information processing apparatus 100, the evaluation unit 134 evaluates whether or not the search result was accepted by the user during the period in which the search result was displayed when the interval at which characters were accepted by the acceptance unit 131 was the longest. do. Thereby, the information processing apparatus 100 can reduce the processing load compared to the case of evaluating whether or not the search result is accepted by the user each time the number of characters changes.

[4-7. Determine the evaluation value using the display count]
The information processing apparatus 100 displays search results each time a character is input by the user. For example, the information processing apparatus 100 determines the number of times each character was displayed when the character string was input and the number of times the search result was accepted by the user in the period from the reception of the character string input to the completion of the character string input. The number of times is counted, and the search results are evaluated according to the ratio between the number of times of display and the number of times the search results are accepted by the user, and the evaluation value of the search results accepted by the user is determined. The information processing apparatus 100 lowers the evaluation value of search results that have been accepted by users less than the number of times displayed, and increases the evaluation value of search results that have been accepted by users more times than the number of times displayed. can be done.

As described above, in the information processing apparatus 100, the evaluation unit 134 determines whether the search result is accepted by the user according to the ratio of the number of times the user has accepted the search result to the number of times the search result is displayed each time the number of characters changes. Determines the evaluation value of search results. As a result, the information processing apparatus 100 can lower the evaluation value of the search result when receiving a character input from the user even though the search result accepted by the user is displayed. Note that if the user continues to input characters to the end despite accepting the search result, the evaluation value of the search result will be unduly low. Therefore, when the above case is assumed, the information processing apparatus 100 may not increase the display count of search results displayed each time the number of characters changes.

[4-8. Evaluate the search results according to the frequency of use by the user]
A user who continues to use the search result display function of the information processing apparatus 100 is considered to be satisfied with the search results displayed by the information processing apparatus 100 so far. Therefore, the information processing apparatus 100 uniformly sets the evaluation value of the search results that have been displayed so far or the evaluation value of the search results that have been displayed during the period in which the function was used more frequently than the specified frequency. may be multiplied by a coefficient to raise the evaluation value.

As described above, in the information processing apparatus 100, the evaluation unit 134 updates the evaluation value of the search result according to the frequency of use of the function of displaying the search result together with the current character string on the display screen. Thereby, the information processing apparatus 100 can appropriately change the evaluation value of the search result according to the user's usage status.

[4-9. Perform some processing on the server]
Although the case where the information processing apparatus 100 performs all the processes has been described, this is an example and the present invention is not limited to this. It is also possible for the server 200 to have a part of the configuration of the information processing apparatus 100 shown in FIG. 2 and to perform a part of the processing. FIG. 8 is a diagram showing a configuration example of the information processing device 100a and the server 200a included in the information processing system 1a according to the embodiment.

The storage unit 220 is realized by, for example, a semiconductor memory device such as a RAM or flash memory, or a storage device such as a hard disk or an optical disk. As shown in FIG. 8 , the storage section 220 has a threshold storage section 121 and an evaluation result storage section 122 . The information stored in the threshold storage unit 121 is the same as the information stored in the threshold storage unit 121 of the information processing apparatus 100 shown in FIG. The information stored in the evaluation result storage unit 122 is the same as the information stored in the evaluation result storage unit 122 included in the information processing apparatus 100 shown in FIG.

(Regarding the control unit 230)
The control unit 230 is a controller. For example, various programs (an example of an information processing program) stored in a storage device inside the information processing apparatus 100 are executed by the CPU, MPU, or the like using the RAM as a work area. Realized. Also, the control unit 230 is, for example, a controller, and is implemented by an integrated circuit such as ASIC or FPGA. The control unit 230 has a search unit 132 and an evaluation unit 134 . The search unit 132 performs processing similar to that of the search unit 132 included in the information processing apparatus 100 shown in FIG. The evaluation unit 134 performs processing similar to that of the evaluation unit 134 included in the information processing apparatus 100 shown in FIG.
