second users

2001 and 2002 are the users to be presented to whom the information processing system 1 presents information. The

second users

2001 and 2002 include, for example, the person in charge of the first user 2100, the doctor in charge, the counselor, the teacher of the school, the boss in the company, and the like. For example, the second user 2001 is a predecessor who is in charge of the first user 2100, and the second user 2002 is a person who is newly in charge of the first user 2100. That is, the second user 2002 is a successor who has taken over the charge of the first user 2100 from the second user 2001. In the following description, when the second user 2001 and the second user 2002 are not distinguished, the second user 2001 and the second user 2002 are described as "second user 2000".

For example, the first user 2100 may reveal confidential information to the second user 2001 when the intimacy with the second user 2001 increases due to a plurality of interviews, dialogues, hospital visits, and the like. However, the confidential information may be information that is not desired to be known to other second users 2002 who have low intimacy (trust). If the successor who does not speak the confidential information knows the confidential information, the first user 2100 may have a feeling of distrust toward the successor or the like. Therefore, the information processing system 1 provides the information processing system 1 that presents the confidential information of the first user 2100 to the second user 200 without causing the first user 2100 to feel distrust.

In the example shown in FIG. 1, the information processing system 1 includes, for example, an information processing terminal 10 and an information processing device 100. In the following description, the information processing system 1 describes an example in which the information processing terminal 10 and the information processing apparatus 100 cooperate with each other to present the confidential information of the first user 2100 to the second user 2000. do.

Further, the information processing apparatus 100 manages the secret information D30 obtained by the dialogue between the first user 2100 and the second user 2001 in the database. In this case, since the relationship information D20 indicates that the relationship between the first user 2100 and the second user 2001 is high, the information processing apparatus 100 presents the presentation information D40 including the secret information D30. In addition, the information processing terminal 10 is controlled.

After that, in step S2, the person in charge of the first user 2100 is changed to the second user 2002, so that the first user 2100 and the second user 2002 do not form an intimate relationship. That is, the first user 2100 and the second user 2002 have a relationship in which the intimacy is lower than the intimacy between the first user 2100 and the second user 2001. The information processing apparatus 100 estimates the relationship between the first user 2100 and the second user 2002 based on the log information D10, and reflects the estimation result in the relationship information D20. In this case, since the relationship information D20 indicates that the intimacy between the first user 2100 and the second user 2001 is low, the information processing apparatus 100 presents the presentation information D40 masking the secret information D30. As such, the information processing terminal 10 is controlled. Alternatively, the information processing apparatus 100 controls the information processing terminal 10 so as to present the presentation information D40 that does not include the secret information D30. As a result, the information processing apparatus 100 can present the presentation information D40, which does not include the secret information D30, to the second user 2002.

After that, in step S3, the intimacy is increased due to the increase in opportunities for the first user 2100 and the second user 2002 to interact with each other. The information processing apparatus 100 estimates that the relationship between the first user 2100 and the second user 2002 is intimate based on the log information D10, and reflects the estimation result in the relationship information D20. In this case, since the relationship information D20 indicates that the first user 2100 and the second user 2002 have a high intimacy relationship, the information processing apparatus 100 presents the presentation information D40 including the secret information D30. In addition, the information processing terminal 10 is controlled. As a result, the information processing apparatus 100 provides the second user 2002 with the presentation information D40 in which the amount of information of the confidential information D30 of the first user 2100 is increased in accordance with the improvement of the intimacy with the first user 2100. Can be presented.

As described above, the information processing apparatus 100 provides the presentation information D40 in which the amount of confidential information D30 contained is increased as the relationship between the second user 2000 and the first user 2100 becomes closer to the second user 2000. Present to. As a result, the information processing apparatus 100 can change the amount of information of the secret information D30 to be presented according to the relationship between the first user 2100 and the second user 2000, so that the second user 2000 to be presented can be changed. The confidential information D30 can be presented to the second user 2000 while avoiding the distrust of the first user 2100. As a result, the information processing apparatus 100 can support communication using the secret information D30 of the first user 2100 by presenting the secret information D30.

The control unit 130 determines whether or not the first user 2100 is the first user based on the recognition result in step S101 (step S102). For example, the control unit 130 determines that the first user 2100 is the first user when the first user 2100 is a user who has never been recognized in the past, based on the management information for managing the user. For example, the control unit 130 determines that the first user 2100 is the first user when the relationship information D20 does not include the information indicating the relationship between the first user 2100 and the second user 2000 recognized in step S101. judge. When the control unit 130 determines that the first user 2100 is not the first user (No in step S102), the control unit 130 advances the process to step S110 described later. Further, when the control unit 130 determines that the first user 2100 is the first user (Yes in step S102), the control unit 130 advances the process to step S103.

The control unit 130 adds the relationship between the first user 2100 and the second user 2000 to the relationship information D20 (step S103). For example, the control unit 130 associates the first identification information indicating the first user 2100 with the second identification information indicating the second user 2000, and sets the initial value “0” as the intimacy of the relationship. Is added to the relationship information D20. When the process of step S103 is completed, the control unit 130 advances the process to step S110.

The control unit 130 executes the estimation loop process of the relationship information D20 (step S110). The end condition of the estimation loop processing is, for example, the end of the dialogue between the first user 2100 and the second user 2000, the end instruction, and the like. When the estimation loop process is executed, the control unit 130 estimates the relationship between the first user 2100 and the second user 2000 based on the sensing information D1 (step S111). For example, the control unit 130 estimates the relationship between the first user 2100 and the second user 2000 based on the sensing information D1 indicated by the log information D10.

In the example shown in FIG. 6, the log information D10 has items of the first identification information, the second identification information, the physical distance, and the date and time. The first identification information is the identification information of the first user 2100, and "C_0001" is set. The second identification information is the identification information of the second user 2000, and "R_0001" is set. The physical distance and the date and time are information obtained by acquiring from the sensing information D1. The control unit 130 recognizes the physical distance between the first user 2100 and the second user 2000, for example, every date or minute, and analyzes whether or not the physical distance has changed. For example, the control unit 130 calculates the average value of the physical distance indicated by the log information D10, the standard deviation (σ), the deviation of the average value, and the square root of the deviation of the average value, as shown in the scene ST1. .. The control unit 130 estimates that the relationship has changed when there is a deviation from the average value of the physical distance indicated by the log information D10. For example, if there is a deviation from the average value, it can be set as a change of 1σ on the premise of a normal distribution. In this case, the control unit 130 estimates that the relationship is shortened when the physical distance is shorter than 3.01 [m] (= σ-1), and the physical distance is 3.35 [m] (= σ + 1). If it spreads more than, it is estimated that the relationship has not deteriorated or changed. In this way, the control unit 130 estimates the relationship based on the change in the state between the second user 2000 and the first user 2100. The control unit 130 may estimate the relationship by combining, for example, a plurality of types of state changes. Returning to FIG. 5, when the process of step S111 is completed, the control unit 130 advances the process to step S112.

The control unit 130 updates the relationship information D20 based on the estimated relationship (step S112). For example, the control unit 130 updates the information indicating the relationship between the corresponding first user 2100 and the second user 2000 based on the estimation result in step S111.

In the example shown in FIG. 7, the relationship information D20 is configured to show the relationship between the first identification information, the second identification information, and the intimacy. In the example shown in FIG. 7, the intimacy can be set in 10 steps, and the larger the set value, the higher the intimacy. The relationship information D20 indicates that the intimacy between the first user 2100 of "C_0001" and the second user 2000 of "R_0001" is "9". The relationship information D20 indicates that the intimacy between the first user 2100 of "C_0001" and the second user 2000 of "R_0002" is "6". Similarly, the relationship information D20 includes information indicating the relationship between the first user 2100 and the second user 2000 of "C_0002".

For example, it is estimated that the relationship between the first user 2100 of "C_0001" and the second user 2000 of "R_0002" is shortened by the process of step S111. In this case, the control unit 130 adds the first user 2100 of "C_0001", the second user 2000 of "R_0002", and the set value of intimacy. In the example shown in FIG. 7, the control unit 130 raises the intimacy by one step. The control unit 130 may change the degree of increase in which the intimacy changes according to the magnitude of the change in the relationship between the first user 2100 and the second user 2000.

Returning to FIG. 5, when the processing of step S112 is completed and the end condition of the loop processing of step S110 is not satisfied, the control unit 130 returns to step S111 and repeats the estimation loop processing. Further, when the processing of step S112 is completed and the end condition of the loop processing of step S110 is satisfied, the control unit 130 ends the processing procedure shown in FIG.

In the present embodiment, the information processing apparatus 100 has described the case where the relationship is estimated by paying attention to the change in the physical distance between the first user 2100 and the second user 2000, but the present invention is not limited to this. The information processing apparatus 100 may be configured to estimate the relationship based on other parameters such as speech volume, body temperature, breathing volume, posture, facial expression, gesture expression volume, and number of eye contacts. The information processing apparatus 100 may be configured to estimate the relationship by combining physical distances and other parameters.

[Example of extraction processing of confidential information according to an embodiment]
FIG. 8 is a flowchart showing an example of the presentation control process executed by the information processing apparatus 100 according to the embodiment. The processing procedure shown in FIG. 8 is realized by the control unit 130 of the information processing apparatus 100 executing a program. The processing procedure shown in FIG. 8 is executed, for example, after the processing procedure shown in FIG. 5 is executed. The processing procedure shown in FIG. 8 is repeatedly executed, for example, during a dialogue between the first user 2100 and the second user 2000. The control unit 130 functions as the presentation control unit 132 by executing the processing procedure shown in FIG.

As shown in FIG. 8, the control unit 130 of the information processing apparatus 100 acquires the information presented to the second user 2000 (step S201). For example, the control unit 130 acquires information to be presented to the second user 2000 who interacts with the first user 2100. For example, the control unit 130 acquires information related to the utterance content of the first user 2100 by referring to a database, confidential information D30, a Web page, and the like. When the control unit 130 stores the acquired information in the storage unit 120, the process proceeds to step S202.

The control unit 130 determines whether or not the secret information D30 of the first user 2100 is included (step S202). For example, the control unit 130 compares the information collected in step S201 with the secret information D30 of the first user 2100, and when the information of the secret information D30 is included, includes the secret information D30 of the first user 2100. It is determined that the information is available. When the control unit 130 determines that the secret information D30 of the first user 2100 is not included (No in step S202), the process proceeds to step S204 described later. Further, when the control unit 130 determines that the secret information D30 of the first user 2100 is included (Yes in step S202), the process proceeds to step S203.

The control unit 130 determines whether or not the intimacy between the first user 2100 and the second user 2000 is equal to or greater than the threshold value (step S203). For example, the control unit 130 identifies the intimacy between the first user 2100 and the second user 2000 based on the relationship information D20, and compares the intimacy with the threshold value for determining the intimacy. The threshold value is, for example, a preset threshold value and can be changed. The threshold value may be included in the program or stored in the storage unit 120, for example. When the control unit 130 determines that the intimacy is equal to or higher than the threshold value (Yes in step S203), the control unit 130 advances the process to step S204.

The control unit 130 executes a process of presenting the acquired information as the presentation information D40 (step S204). For example, the control unit 130 generates the presentation information D40 based on the information acquired in step S201, and controls the information processing terminal 10 so as to present the generated presentation information D40. For example, the control unit 130 generates presentation information D40 for presenting the acquired information in a list, and instructs the information processing terminal 10 to present the presentation information D40 via the communication unit 110. As a result, the information processing terminal 10 presents the presentation information D40 including the secret information D30 to the second user 2000. When the process of step S204 is completed, the control unit 130 ends the process procedure shown in FIG.

If the control unit 130 determines that the intimacy is not equal to or higher than the threshold value (No in step S203), the control unit 130 proceeds to step S205. The control unit 130 executes a process of presenting the presentation information D40 masking the secret information D30 (step S205). For example, the control unit 130 generates the presentation information D40 masking the secret information D30 from the acquired information, and controls the information processing terminal 10 so as to present the generated presentation information D40. For example, the control unit 130 generates the presentation information D40 for deleting the secret information D30 from the acquired information and presenting it, and instructs the information processing terminal 10 to present the presentation information D40 via the communication unit 110. As a result, the information processing terminal 10 presents the presentation information D40, which does not include the secret information D30 or has a limited amount of information of the secret information D30, to the second user 2000. When the process of step S204 is completed, the control unit 130 ends the process procedure shown in FIG.

In the present embodiment, the information processing apparatus 100 describes a case where the amount of information including the secret information D30 in the presentation information D40 is changed by using one threshold value, but the present invention is not limited to this. The information processing apparatus 100 may be configured to determine the intimacy stepwise using a plurality of different threshold values and gradually increase the amount of information of the secret information D30 included in the presentation information D40.

[Presentation example of information processing device according to the embodiment]
FIG. 9 is a diagram showing a presentation example of the presentation information D40 of the information processing apparatus 100 according to the embodiment. In the scene C1 shown in FIG. 9, the relationship information D20 shows a value in which the intimacy between the first user 2100 and the second user 2000 is lower than the above-mentioned threshold value. In this case, the information processing apparatus 100 acquires the information about the first user 2100 to be presented to the second user 2000, and generates the presentation information D41 not including the secret information D30 based on the acquired information. The information processing apparatus 100 controls the information processing terminal 10 so as to present the generated presentation information D41.

In the example shown in the scene C1, the information processing apparatus 100 causes the information processing terminal 10 to present the presentation information D41 showing a list of hobbies as information regarding the first user 2100. The presented information D41 is, for example, information showing a list of baseball, cycling, and travel, which are the hobbies of the first user 2100. In this case, the information processing apparatus 100 does not include the secret information D30 in the presentation information D40.

After that, in the scene C2, the relationship information D20 changes the intimacy between the first user 2100 and the second user 2000 to a value equal to or higher than the above threshold value. In this case, the information processing apparatus 100 acquires information about the first user 2100 presented to the second user 2000, and generates presentation information D42 including confidential information D30 based on the acquired information. The information processing apparatus 100 controls the information processing terminal 10 so as to present the generated presentation information D42.

In the example shown in the scene C2, the information processing apparatus 100 causes the information processing terminal 10 to present a list of hobbies and presentation information D42 indicating confidential information D30 as information regarding the first user 2100. The presented information D42 includes, for example, information indicating a list of baseball, cycling, and travel, which is a hobby of the first user 2100, and information indicating asthma included in the confidential information D30. The presentation information D42 is configured to present information indicating a list of hobbies and confidential information D30 in different display modes. As a result, the information processing apparatus 100 can make the presented second user 2000 recognize the secret information D30 in the presented information D40.

As described above, the information processing apparatus 100 presents the presentation information D40 including the secret information D30 of "asthma" to the second user 2000 when the relationship between the second user 2000 and the first user 2100 becomes intimate. do. As a result, the information processing apparatus 100 can present the confidential information D30 to the second user 2000 while avoiding the distrust of the first user 2100 with respect to the second user 2000 to be presented. As a result, the information processing apparatus 100 can support communication using the secret information D30 of the first user 2100 by changing the secret information D30 included in the presentation information D40 according to the intimacy.

[Example of extraction processing of confidential information according to an embodiment]
The information processing device 100 can use the secret information D30 registered in the database by an external device or the like, or can extract the secret information D30 from the utterance content of the first user 2100. FIG. 10 is a flowchart showing an example of the extraction process of the secret information D30 executed by the information processing apparatus 100 according to the embodiment. FIG. 11 is a diagram for explaining the concept of extracting the secret information D30 according to the embodiment.

The processing procedure shown in FIG. 10 is realized by the control unit 130 of the information processing apparatus 100 executing a program. The processing procedure shown in FIG. 10 is executed, for example, at the timing when the sensing information D1 regarding the dialogue between the first user 2100 and the second user 2000 is collected, the timing when the dialogue is started, the timing set in advance, and the like. The control unit 130 functions as the extraction unit 133 by executing the processing procedure shown in FIG.

As shown in FIG. 10, the control unit 130 of the information processing apparatus 100 executes the extraction loop process of the secret information D30 (step S300). The end condition of the extraction loop process is, for example, the end of the dialogue, the end instruction, and the like. When the extraction loop process is executed, the control unit 130 acquires utterance information based on the sensing information D1 (step S301). For example, the control unit 130 semantically analyzes the utterance information of the first user 2100 indicated by the sensing information D1 and acquires the utterance information including the keyword from the analysis result. The control unit 130 extracts confidential information from the utterance information (step S302).

For example, suppose that the utterance information indicates the utterance text of "I went to visit my uncle yesterday and found out that my uncle had a stomach ulcer ...". For example, the control unit 130 can use a method of using the noun extracted from the utterance information as it is. In this case, the control unit 130 analyzes the utterance information by morphological analysis and part-of-speech analysis, and extracts a keyword (noun). The keywords extracted from the above-mentioned utterance information include, for example, "uncle", "sympathy", "stomach ulcer" and the like. The control unit 130 extracts the extracted keyword as the secret information D30 of the first user 2100.

For example, the control unit 130 can use a method of using weighting for keywords (nouns) extracted from utterance information. As the weighting, for example, TF-IDF (Term Frequency-Inverse Document Frequency) or the like can be used. The control unit 130 scores the importance of the keyword so that the characteristic word is positioned at the top.

As shown in FIG. 11, the information processing apparatus 100 has a configuration capable of managing a plurality of utterance information for each of a plurality of first users 2100. In the example shown in FIG. 11, the information processing apparatus 100 has a plurality of first utterance information, a second utterance information, and a third utterance information for each first user 2100 such as "C_0001", "C_0002", and "C_0003". It manages utterance information, etc. In the present embodiment, the control unit 130 can perform scoring (weighting) of the importance of the keywords in the pattern PT1 and the pattern PT2. The pattern PT1 is a pattern for scoring so as to express the characteristics of the utterance information among all the first users 2100. The pattern PT2 is a pattern for scoring so as to express the characteristics of the utterance information in all the utterance information of the specific first user 2100. In the example shown in FIG. 11, the pattern PT2 shows that scoring is performed so as to express the characteristics of the utterance information in all the utterance information of the first user 2100 of “C_0001”. Then, the control unit 130 extracts a keyword whose score is higher than the score threshold value as confidential information of the first user 2100. As a result, the information processing apparatus 100 can extract a meaningful keyword as the secret information D30 as compared with Buu who uses the keyword extracted from the utterance information as it is.

Returning to FIG. 10, when the process of step S302 is completed, the control unit 130 advances the process to step S303. The control unit 130 determines whether or not the intimacy between the first user 2100 and the second user 2000 is equal to or greater than the threshold value (step S303). For example, the control unit 130 extracts the intimacy corresponding to the first user 2100 and the second user 2000 from the relationship information D20, and when the intimacy is equal to or more than a preset threshold value, the intimacy is equal to or more than the threshold value. judge. When the control unit 130 determines that the intimacy between the first user 2100 and the second user 2000 is equal to or higher than the threshold value (Yes in step S303), the control unit 130 advances the process to step S304.

The control unit 130 registers the extracted secret information D30 so that the first user 2100 can identify it (step S304). For example, the control unit 130 associates the extracted secret information D30 with information that can identify the first user 2100 and stores it in the storage unit 120, or registers it in the database. When the processing of step S304 is completed and the end condition of the loop processing of step S300 is not satisfied, the control unit 130 returns to step S301 and repeats the extraction loop processing. Further, when the processing of step S304 is completed and the end condition of the loop processing of step S300 is satisfied, the control unit 130 ends the processing procedure shown in FIG.

Further, when the control unit 130 determines that the intimacy between the first user 2100 and the second user 2000 is not equal to or higher than the threshold value (No in step S303), the control unit 130 determines the end condition of the loop processing in step S300. If the control unit 130 does not satisfy the end condition of the loop processing in step S300, the control unit 130 returns to step S301 and repeats the extraction loop processing. Further, the control unit 130 ends the processing procedure shown in FIG. 10 when the end condition of the loop processing in step S300 is satisfied.

[Example of extracting confidential information of the information processing device according to the embodiment]
Next, an example will be described in which the information processing apparatus 100 according to the embodiment extracts confidential information from the utterance content of the first user 2100. FIG. 12 is a diagram for explaining an example of extracting keywords of the information processing apparatus 100 according to the embodiment. FIG. 13 is a diagram for explaining an example of extracting the secret information D30 from the utterance information. In FIG. 12, the information processing terminal 10 is omitted for the sake of simplicity of explanation.

In the example shown in FIG. 12, the first user 2100 is interacting with the second user 2000. The first user 2100 emits the utterance information W1 to the second user 2000. The utterance information W1 is, for example, "It's hot today." After that, the first user 2100 emits the utterance information W2 in response to the response R1 of the second user 2000. The utterance information W2 is, for example, "I went to the hospital yesterday." After that, the first user 2100 emits the utterance information W3 in response to the response R2 of the second user 2000. The utterance information W3 is, for example, "for asthma treatment." After that, the first user 2100 emits the utterance information W4 in response to the response R3 of the second user 2000. The utterance information W4 is, for example, "After all, asthma treatment is difficult."

When the information processing apparatus 100 detects that the dialogue between the first user 2100 and the second user 2000 has ended, it extracts "today" and "hot" as keywords from the utterance information W1 acquired and semantically analyzed. The information processing apparatus 100 extracts "yesterday" and "hospital" as keywords from the utterance information W2 acquired and semantically analyzed. The information processing apparatus 100 extracts "asthma treatment" as a keyword from the utterance information W3 acquired and semantically analyzed. The information processing apparatus 100 extracts "asthma treatment" and "difficult" as keywords from the utterance information W4 acquired and semantically analyzed.

In the present embodiment, the information processing apparatus 100 describes a case where the secret information D30 is extracted after the dialogue between the first user 2100 and the second user 2000 is completed, but the present invention is not limited to this. For example, the information processing apparatus 100 may be configured to extract the secret information D30 during the dialogue between the first user 2100 and the second user 2000.

As shown in FIG. 13, when the information processing apparatus 100 extracts keywords from the utterance information W1, W2, W3, and W4, the information processing apparatus 100 uses TF-IDF to weight each of the plurality of keywords. The information processing apparatus 100 can use the following equations (1), (2), and (3). In the present embodiment, in order to simplify the explanation, the information processing apparatus 100 describes a case where the secret information D30 is extracted from the four utterance information W1, W2, W3, and W4, but the number of utterance information is Not limited to this.

The information processing apparatus 100 calculates TF (word, document), which is the frequency of appearance of words, using the equation (1). TF (word, document) calculates the frequency of appearance of a word in a document by dividing the frequency of occurrence of the word in the document by the sum of the frequency of appearance of all words in the document.

For example, when the information processing apparatus 100 extracts "today" from the utterance information W1 as a keyword, it calculates by TF (today, W1) with the word "today" and the document as the utterance information W1. In this case, the information processing apparatus 100 obtains a calculation result in which the frequency of appearance of words is 1, the sum of the frequency of appearance of all words in a document is 2, and the frequency of appearance is 0.5. Further, when the information processing apparatus 100 extracts "asthma treatment" as a keyword from the utterance information W3, the information processing apparatus 100 calculates by TF (asthma treatment, W3) in which the word is "asthma treatment" and the document is the utterance information W3. In this case, the information processing apparatus 100 obtains a calculation result in which the frequency of appearance of words is 1, the sum of the frequency of appearance of all words in a document is 1, and the frequency of appearance is 1. Then, the information processing apparatus 100 calculates the appearance frequency for other keywords in the same manner.

Next, the information processing apparatus 100 calculates the IDF (word), which is the reverse document frequency, using the equation (2). The frequency of reverse documents is higher as the word is rare, and lower as the word appears more frequently in various documents. The IDF (word) calculates the rarity of a word by calculating the logarithm of the value obtained by dividing the total number of documents by the number of documents including the word.

For example, when the information processing apparatus 100 extracts "today" as a keyword from the utterance information W1, it calculates by IDF (today) with the word "today". In this case, the information processing apparatus 100 obtains a calculation result in which the total number of documents is 4, the number of documents including words is 1, and the reverse document frequency is 1.6. Further, when the information processing apparatus 100 extracts "asthma treatment" as a keyword from the utterance information W3, it calculates by IDF (asthma treatment) with the word "asthma treatment". In this case, the information processing apparatus 100 obtains a calculation result in which the total number of documents is 4, the number of documents including words is 2, and the reverse document frequency is 1.3. Then, the information processing apparatus 100 similarly calculates the reverse document frequency for other keywords.

Next, the information processing apparatus 100 calculates TF-IDF (TF * IDF), which is the importance (rareness) of the word, using the equation (3). The importance is obtained by calculating the above-mentioned TF (word, document) * IDF (word).
TF * IDF = TF (word, document) * IDF (word) ・・・ Equation (3)

For example, when the information processing apparatus 100 extracts "today" as a keyword from the utterance information W1, it calculates TF (today, W1) * IDF (today) = 0.5 * 1.6. In this case, the information processing apparatus 100 obtains a calculation result having an importance of 0.8. Further, when the information processing apparatus 100 extracts "asthma treatment" as a keyword from the utterance information W3, the information processing apparatus 100 calculates TF (asthma treatment, W3) * IDF (asthma treatment) = 1 * 1.3. In this case, the information processing apparatus 100 obtains a calculation result having an importance of 1.3. Further, when the information processing apparatus 100 extracts "asthma treatment" as a keyword from the utterance information W4, the information processing apparatus 100 calculates TF (asthma treatment, W4) * IDF (asthma treatment) = 0.5 * 1.3. In this case, the information processing apparatus 100 obtains a calculation result having an importance of 0.7. Then, the information processing apparatus 100 similarly calculates the reverse document frequency for other keywords.

The information processing apparatus 100 extracts a keyword of importance whose importance is equal to or higher than the extraction threshold value from the importance calculated for all keywords. Alternatively, the information processing apparatus 100 extracts the keyword having the highest importance from the importance calculated for all the keywords. In the example shown in FIG. 13, the information processing apparatus 100 extracts "asthma treatment" having a importance of 1.3 as confidential information D30. For example, the information processing apparatus 100 registers the extracted secret information D30 in the database by associating the first identification information that can identify the first user 2100 with the registration date / time information.

FIG. 14 is a diagram showing an example of the confidential information D30 according to the embodiment. As shown in FIG. 14, the secret information D30 is configured to include information indicating the secret (keyword) of the first user 2100. The secret information D30 is associated with the first identification information and the registration date / time information. In the example shown in FIG. 14, the first user 2100 whose first identification information is "C_0001" indicates that the secret information D30 of "stomach ulcer", "karaoke" and "property purchase" is registered in the database. .. The first user 2100 whose first identification information is "C_0002" indicates that the secret information D30 of "asthma treatment" is registered in the database. The secret information D30 may be associated with the second identification information that can identify the second user 2000 that was interacting with the first user 2100 when it was extracted.

As described above, when the information processing apparatus 100 acquires the secret information D30 of the first user 2100 as the information to be presented to the second user 2000, the intimacy between the first user 2100 and the second user 2000 is equal to or higher than the threshold value. If there is, the information processing terminal 10 is made to present the presentation information D40 including the confidential information D30. For example, when the second user 2000 in charge of the first user 2100 is changed, the intimacy between the new second user 2000 and the first user 2100, which succeeds the user 2000, becomes the initial state. In this case, when the information processing apparatus 100 acquires the secret information D30 of the first user 2100 as the information to be presented to the second user 2000, the intimacy with the first user 2100 is not equal to or more than the threshold value, so that the secret information D30 The information processing terminal 10 is made to present the presentation information D40 that does not include the above. As a result, the information processing apparatus 100 does not need to cause the user to set or change the relationship between the first user 2100 and the second user 2000, so that the deterioration of convenience is suppressed and the first user 2100 Communication using the confidential information D30 can be supported.

[Example of presentation of presentation information of information processing apparatus according to an embodiment]
Next, an example in which the information processing apparatus 100 according to the embodiment presents the presentation information D40 including the secret information D30 will be described. FIG. 15 is a diagram for explaining a presentation example of the presentation information D40 including the secret information D30 according to the embodiment.

As shown in FIG. 15, when the information processing apparatus 100 presents the secret information D30 to the second user 2000, the information processing terminal 10 is made to present the presentation information D40 that presents the related information D50 related to the secret information D30. .. The related information D50 may be stored as a database corresponding to the keyword, or may be acquired from a website.

For example, when the secret information D30 is "colon surgery", the information processing apparatus 100 acquires the related information D50 related to "colon surgery". Related information D50 includes, for example, information such as "It seems that a low-fat diet is good for colorectal surgery." Related information D50 includes, for example, information and illustrations of "Please eat a low-fat diet after colorectal surgery." Based on the acquired related information D50, the information processing apparatus 100 generates presentation information D40 for instructing the second user 2000 to "meal with low carbohydrate", and presents the presentation information D40 to the information processing terminal 10. Let me.

Further, for example, when the secret information D30 is the "surplus", the information processing apparatus 100 acquires the related information D50 related to the "surplus". For example, the information processing device 100 proposes a property that is expensive but the asset value does not easily decrease if there is surplus, based on the dialogue log of the person in charge at the time of real estate business and information showing past cases. It is assumed that the information indicating "Masu." Is acquired. In this case, the information processing apparatus 100 generates the presentation information D40 that prompts the proposal of "a property that is expensive but the asset value does not easily decrease", and causes the information processing terminal 10 to present the presentation information D40.

[Modification example of presentation information of information processing apparatus according to the embodiment]
Next, an example will be described in which the information processing apparatus 100 according to the embodiment transforms the presentation information D40 including the secret information D30. FIG. 16 is a diagram for explaining a modification of the presentation information D40 including the secret information D30 according to the embodiment.

As shown in FIG. 16, the information processing apparatus 100 can conceptualize the secret information D30 to the conceptual information D60 based on the intimacy between the first user 2100 and the second user 2000. For example, the control unit 130 of the information processing apparatus 100 acquires the concept information D60 corresponding to the secret information D30 by using a concept dictionary, a database, or the like, and generates the presentation information D40 including the concept information D60. For example, when the secret information D30 is "colon surgery", "cerebral neurosurgery", "cardiac surgery", etc., the control unit 130 acquires the conceptual information D60 indicating "surgery" which is a higher-level conceptualization of the secret information D30. .. For example, when the secret information D30 is a "surplus", a "pension", or the like, the control unit 130 acquires the conceptual information D60 indicating "money" which is a higher-level conceptualization of the secret information D30.

For example, when the intimacy between the first user 2100 and the second user 2000 is lower than the threshold value, the control unit 130 of the information processing apparatus 100 generates the presentation information D40 including the conceptual information D60. As a result, the control unit 130 can make the information processing terminal 10 present the presentation information D40 showing the higher-level conceptualized information without directly showing the secret information D30. As a result, the information processing apparatus 100 can support communication between the first user 2100 and the second user 2000 by using the information similar to the secret information D30 without presenting the secret information D30.

[Modified example of presentation control processing of the information processing apparatus according to the embodiment]
FIG. 17 is a flowchart showing a modified example of the presentation control process executed by the information processing apparatus 100 according to the embodiment. The processing procedure shown in FIG. 17 is realized by the control unit 130 of the information processing apparatus 100 executing a program. The processing procedure shown in FIG. 17 is repeatedly executed, for example, during a dialogue between the first user 2100 and the second user 2000. The control unit 130 functions as the presentation control unit 132 by executing the processing procedure shown in FIG.

In the processing procedure shown in FIG. 17, since the processing from step S201 to step S204 is the same as the processing from step S201 to step S204 shown in FIG. 8, detailed description thereof will be omitted.

As shown in FIG. 17, the control unit 130 of the information processing apparatus 100 acquires the information presented to the second user 2000 (step S201). The control unit 130 determines whether or not the secret information D30 of the first user 2100 is included (step S202). When the control unit 130 determines that the secret information D30 of the first user 2100 is not included (No in step S202), the process proceeds to step S204 described later. Further, when the control unit 130 determines that the secret information D30 of the first user 2100 is included (Yes in step S202), the process proceeds to step S203.

The control unit 130 determines whether or not the intimacy between the first user 2100 and the second user 2000 is equal to or greater than the threshold value (step S203). When the control unit 130 determines that the intimacy is equal to or higher than the threshold value (Yes in step S203), the control unit 130 advances the process to step S204. The control unit 130 executes a process of presenting the acquired information as the presentation information D40 (step S204), and ends the processing procedure shown in FIG.

If the control unit 130 determines that the intimacy is not equal to or higher than the threshold value (No in step S203), the control unit 130 proceeds to step S211. The control unit 130 acquires the conceptual information D60, which is a higher-level conceptualization of the secret information D30 (step S211). For example, the control unit 130 acquires the concept information D60 such as a word or a noun indicated by the secret information D30 from a concept dictionary, a database, or the like. When the process of step S211 is completed, the control unit 130 advances the process to step S212.

The control unit 130 does not show the secret information D30, but executes a process of presenting the presentation information D40 including the concept information D60 (step S212). For example, the control unit 130 generates the presentation information D40 based on the acquired conceptual information D60, and controls the information processing terminal 10 so as to present the generated presentation information D40. For example, when the conceptual information D60 indicates “surgery”, the control unit 130 generates presentation information D40 that prompts the second user 2000 to ask a question about surgery history, medical history, etc. in a dialogue, and displays the presentation information D40. Have the information processing terminal 10 present it. For example, when the conceptual information D60 indicates "money", the control unit 130 generates presentation information D40 that prompts the second user 2000 to ask a question about the asset status or the like in a dialogue, and processes the presentation information D40. Have the terminal 10 present it. As a result, the information processing terminal 10 presents the presentation information D40 indicating the conceptual information D60 to the second user 2000 without including the secret information D30. When the process of step S212 is completed, the control unit 130 ends the process procedure shown in FIG.

In this way, the information processing apparatus 100 can support communication using the conceptual information D60, which is a higher-level conceptualization of the secret information D30, by presenting the presentation information D40 to the information processing terminal 10. Then, the second user 2000 recognizes that the first user 2100 has a secret regarding the concept information D60 by referring to the concept information D60 indicated by the presentation information D40, and asks the concept information D60 in the dialogue. You can check.

Further, when the conceptual information D60 is used, the information processing apparatus 100 can generate the presentation information D40 that prompts the second user 2000 to ask the question of the conceptual information D60. For example, when the conceptual information D60 indicates "surgery", the information processing apparatus 100 presents the information processing terminal 10 with the presentation information D40 prompting the second user 2000 to ask a question about the surgery history, medical history, etc. in a dialogue. Let me. By referring to the presentation information D40, the second user 2000 can ask the first user 2100 a surgical history, a medical history, and the like in a dialogue. Thereby, the information processing apparatus 100 can support the second user 2000 to acquire the information about the secret information D30 without presenting the secret information D30. As a result, the information processing apparatus 100 can support communication based on the secret information D30 without presenting the secret information D30.
