[1-2. Example of decision processing]
Here, when delivering the content to the user, a technique of delivering the selected content by selecting the content presumed to be of interest to the user based on the user's attribute or statement is considered. Be done. Based on such a technique, for example, a method of identifying a product that a user belonging to the community C01 is talking about and providing an advertisement of the identified product to a user belonging to the community C01 can be considered. However, such technology may not be able to effectively deliver information such as advertisements.

  For example, it is conceivable that users forming a pair, such as a couple and a lover, will perform the same purchasing behavior based on not only the taste of each person but also the taste of the pair. In addition to the pair, in a group that satisfies a certain condition, it is considered that a plurality of users who belong to the group perform similar purchasing behavior based on the taste of the group. However, in the related art, since the taste of the user who acts as such a pair or group is not taken into consideration, it may not be said that the advertisement is effectively delivered.

  Therefore, the decision device 10 considers that not only the tastes of individual users such as their mental states but also the tastes of users belonging to a pair that satisfy a predetermined condition are unified, and the provision of information such as advertisements. Determine the mode. That is, the determination device 10 determines the provision mode of the information to be provided to the community C01 in consideration of the micro viewpoint such as the state of each user and the macro viewpoint such as the state of the community C01.

  Specifically, the determination device 10 identifies a pair of users. Then, the determination device 10 regards the paired users as particles that condense Bose, and considers the amount of information between the users as the amount of heat, and indicates the phase transition between the superconducting state and the normal conducting state. The mode of providing information to the user is determined based on the phase information.

  For example, the determination device 10 considers a user belonging to the community C01 as a pair, such as a user in a marriage relationship or a user in a lover relationship, from the information registered in the SNS or the like, the content of the message, and the like. Identify users who can. Further, the determining apparatus 10 considers each user belonging to the community C01 as a fermion particle, and considers the users who can be considered as a pair as the users who will be Bose-condensed and become the Bose particles. Assume a corresponding system. Then, the determining apparatus 10 considers the amount of information in the community C01 as the amount of heat, and provides information to the community C01 based on the phase information indicating the phase transition between the superconducting state and the normal state in the corresponding system. To decide.

  The contents of the determination process executed by the determination device 10 will be described below. First, consider a phenomenon when an advertisement for a certain product is distributed to the community C01. For example, considering the purchasing behavior and mental situation of each user, each user is considered to have an independent purchasing behavior or have an independent mental situation. Therefore, assuming a system corresponding to the community C01 (hereinafter, referred to as “corresponding system”), the determining apparatus 10 may take particles that do not cause duplicate behavior of each user, that is, the same state. It is thought that it can be regarded as a fermion that cannot.

  Further, when each user is in a different psychological state within the community C01, an advertisement of a specific product (hereinafter, referred to as “specific product”) is distributed to any of the users. Even so, it is considered that the information does not spread much (is not propagated) within the community C01. It is considered that such a state can be regarded as the normal state of the phase of the corresponding system when the information propagation is regarded as the current propagation in the corresponding system.

  On the other hand, when each user in the community C01 is in a paired state, when an advertisement of a specific product is delivered to any one of the users, the information is transmitted to the users belonging to the pair, It is thought that they will take similar consumption behavior. Therefore, users belonging to the pair can be regarded as Bose-condensed fermions in the corresponding system. Therefore, when many users in the community C01 are paired, if the information propagation is regarded as the current propagation in the corresponding system, the phase of the corresponding system causes Bose condensation and is in a superconducting state. It is thought that it can be considered.

  Therefore, the determination device 10 regards each user of the community C01 as a fermion particle and the paired users as particles for Bose condensation. Then, the determining apparatus 10 considers the state of the phase of the corresponding system as the state in the community C01 and determines the effective advertisement distribution mode for the community C01. More specifically, the determination apparatus 10 determines the temperature at which the superconducting state and the normal state undergo a phase transition (hereinafter referred to as “critical temperature”) in the corresponding system of the community C01 by the BCS theory (Bardeen Cooper Schrieffer theory). ). Then, the determining device 10 regards the amount of information regarding the specific product in the community C01 as the amount of heat, identifies the state in the corresponding system, and determines whether the state of the corresponding system is the normal conducting state or the superconducting state. Accordingly, the distribution mode of the advertisement is determined.

[1-3. Example of fitting]
Here, in order to execute the determination process described above, the amount of information in the community C01 is applied to the energy in the system corresponding to the community C01, and the user is regarded as a particle constituting the system, and the thermodynamics and The phase information of the system will be calculated based on the BCS theory. Therefore, in the following description, an example of fitting will be described. Note that the following fitting is merely an example, and any fitting may be adopted as long as a value based on the amount of information is used as an index of system energy. Further, in the fitting described below, the determination device 10 may execute processing in consideration of arbitrary counting and weighting. In addition, in the following description, information related to a specific product may be simply referred to as “information”.

  For example, the number of times a user belonging to the community C01 has accessed content or media (hereinafter, collectively referred to as “media”) related to a specific product is referred to as a system corresponding to the community C01 (hereinafter referred to as “corresponding system”). .) Can be regarded as a value indicating the degree of energy inside, that is, temperature. Therefore, the determining apparatus 10 sets a value based on the number of times a user belonging to the community C01 has accessed a medium in a predetermined field (hereinafter, referred to as “media access number”) to a corresponding system temperature value “T”. ". For example, the determination device 10 uses, as the number of media accesses, the number of times the news and advertisements related to a specific product, the number of times a blog or the like posted by another user for a specific product is viewed, the number of times of acquisition, and the number of times when distribution is accepted. Get for each person. Then, the determining apparatus 10 calculates the value “T” indicating the temperature of the corresponding system based on the number of media accesses of each user who belongs to the community C01. Note that the determination device 10 determines not only a medium including the name of a specific product, that is, a medium directly related to the specific product, but also a medium corresponding to the specific product such as a store or a media that suggests the specific product. The number of media accesses for media indirectly related to the product may be acquired.

  In addition, among the users belonging to the community C01, the number of users who are potentially interested in the specific product, the amount of information that only the specific user can view, and the like are the potential for the specific product in the community C01. Such interest can be regarded as energy that is not manifested as heat quantity or the like in the energy of the corresponding system, that is, internal energy. Therefore, the determination device 10 may calculate the value “U” of the internal energy based on the value indicating the degree of potential interest in the specific product in the community C01. For example, the determination device 10 determines the amount of information that can be viewed only by a specific user, not the bulletin board or the like, such as the amount of messages related to a specific product among messages exchanged only between users. Obtained as a value indicating the degree of interest. Further, the determination device 10 acquires the number of users who have transmitted the message related to the specific product only to the specific user, as a value indicating the degree of potential interest. Then, the determination device 10 calculates the value “U” of the internal energy based on each acquired value. In addition to the above-described information, the determination device 10 may calculate the value “U” of the internal energy in consideration of any information as long as the information indicates a potential degree of interest in the community C01. ..

  Further, the number of users belonging to the community C01 can be regarded as information indicating the size of the corresponding system. Therefore, the determination device 10 regards the number of users belonging to the community C01 as the number of particles that configure the corresponding system.

  Here, it is predicted that the paired or grouped users will carry out the purchasing behavior as a paired or grouped regardless of the fashion in the community. That is, users in pairs or groups are less likely to be affected by external noise (advertisements, messages, etc.). For this reason, users in pairs or groups can be considered to be in a superconducting state and in a state in which they are hardly affected by an external magnetic field. On the other hand, a magnetic field from the outside enters the system in the normal conduction state, but in the system in the superconducting state, a force acts to remove the magnetic field from the inside of the system, and the magnetic field is transmitted to the outside. Pushed out. As a result, when an external magnetic field is applied to the superconducting system, the magnetic field penetrates by a length called London penetration length. Therefore, the amount of invasion in London can be regarded as the sensitivity of the system corresponding to the pair or group to the external magnetic field, that is, the influence (sensitivity) of advertisements or messages corresponding to the pair or group. Therefore, the determination device 10 regards the influence of the advertisement or the message on the pair or the group as the invasion length of London.

  For example, when the determination device 10 distributes information about a specific product to some of the users belonging to a pair or a group, how much information about the specific product is transmitted to other users. Taka is specified as the information indicating the influence based on the content of the message, the posted content of the SNS, and the like. Further, the decision device 10 determines how much each user has purchased a specific product when the information of the specific product is distributed to the users belonging to the pair or the group, as information indicating the influence, such as a purchase history. Based on. Then, the determination device 10 may calculate a value based on the information indicating the specified influence and consider the calculated value as the intrusion length of London.

  Further, when the critical temperature “Tc” is calculated using the BCS theory, calculation using an operator called a generation operator is performed. Here, the generation operator is an operator that increases the number of particles in the Bose condensation state by one. Therefore, the generation operator can be regarded as the amount of interest in the specific product. Therefore, the determination device 10 acquires the amount of information regarding the specific product posted by the user belonging to the community C01 on the SNS, the amount of the message related to the specific product, and the like, and generates a value based on the acquired amount as a generation operator. Correspond to.

  Based on the above-mentioned fitting, the determination device 10 calculates the critical temperature "Tc" at which the corresponding system transitions to the superconducting state, as phase information, using the BCS theory and an equation called a gap equation. Further, based on the above-mentioned fitting, the determination device 10 calculates the temperature and energy of the corresponding system at the time of information distribution. Then, the determining device 10 determines the distribution mode of the advertisement based on whether the corresponding system is in the normal conduction state or the superconducting state at the time of information distribution.

[1-4. Example of processing using phase information]
In addition, the determination device 10 uses the generated phase information to determine the mode of distributing the advertisement of the specific product. For example, the determination device 10 calculates the value of the amount of heat and the value of the pressure required until the corresponding system undergoes the phase transition based on the phase information. More specifically, the determination device 10 specifies how much the advertisement distribution amount needs to be reduced before the particles generate Bose condensation in the corresponding system and have the same behavior as a whole. Then, the determination device 10 reduces the advertisement distribution amount by the specified amount. Then, when the state of the corresponding system becomes the superconducting state, the determining device 10 delivers all the advertisements smaller than those in the case of the normal conducting state, and affects all users corresponding to the Bose condensed particles. Can be given. As a result, the determination device 10 can reduce the advertising cost as compared with distributing the advertisement of each user. That is, the determination device 10 can improve the effect on the advertising cost.

[1-5. Example of mathematical formula]
Next, an example of a mathematical formula used when the determination device 10 calculates the phase information will be described. In addition, about the concrete derivation | leading-out method of the following formula | equation, for example, nonpatent literature 1 ("Theory of Superconductivity" J.Bardeen, LNCooper, JRSchrieffer, Physical Review Volume 108, Number 5, December 1, 1957) and non-patent literature. It is detailed in Patent Document 2 (http://www.phys.aoyama.ac.jp/~w3-jun/achievements/study_sc_chara.html, Internet, search on July 15, 2016).

For example, assuming that there is a corresponding superconducting pair on the positive side of the x-axis and a magnetic field B ₀ is applied in the z-axis direction, the magnetic field inside the superconductor is given by the following equation (1). Can be expressed as Here, “x” indicates the coordinate in the x-axis direction of the position where the magnetic field is to be calculated, and “λ _L ” is how inner the position where the magnetic field is to be calculated is from the surface of the corresponding system. It is the indicated value.

Next, a process of calculating the critical temperature “Tc” will be described. For example, the gap equation that can be obtained from the Hamiltonian in BCS theory can be expressed by the following equation (2). Here, when “Δ _k ” shown in the equation (2) is doubled, it corresponds to the value of the superconducting gap which is the energy required to break the state in which Bose condensation has occurred as a Cooper pair. In such a gap equation, the determination device 10 determines the critical temperature "Tc" at which the phase changes from the normal state to the superconducting state based on the energy value, the superconducting gap value, the number of particles in the corresponding system, and the like. It can be calculated.

  Further, V (k, k ') in the equation (2) can be expressed by the following equation (3). In such a gap equation, the critical temperature “Tc” can be regarded as a temperature at which mass media information such as an advertisement or the like makes a transition to a state where it does not enter the corresponding system. Therefore, the determination device 10 calculates the critical temperature "Tc" from the equations (2) and (3), assuming that the information of the mass media is not entered from the outside below the critical temperature "Tc".

  In quantum mechanics, the wave function of two bodies can be expressed by the following equation (4).

Here, considering the second quantization, the equation (4) can be transformed into the equation (5). Here, “c ^* _{k ↑} ” and “c ^* _{-k ↓} ” shown in Expression (5) are generation operators and correspond to an increase in interest in a specific product in the community C01.

  The wave function in the BCS theory can be expressed by the following equation (6).

As a result, the ground state of the wave function in BCS theory can be expressed by the following equation (7). Here, “u _k ” in the equation (7) is a coefficient corresponding to the unoccupied probability of the electron pair, that is, the number of unpaired users among the users belonging to the community C01, and “v _k ”. “ _{K 2} ” is a coefficient corresponding to the probability of occupying the electron pair, that is, the number of paired users among the users belonging to the community C01.

  The determination device 10 calculates, as the phase information, the critical temperature “Tc” at which the phase transition occurs in the corresponding system of the community C01, based on the equations (1) to (7) described above. Then, the determination device 10 determines the distribution mode of the advertisement to the community C01 based on the calculated critical temperature “Tc”.

[1-6. Example of decision processing]
Next, an example of the determination process executed by the determination device 10 will be described with reference to FIG. First, the determination device 10 acquires various kinds of information amount regarding the community C01 as parameters (step S1). For example, the determination device 10 collects various kinds of information necessary for the above fitting from the community server 110, the media server 120, the electronic commerce server 130, and the like. Then, the determination device 10 considers each user belonging to the community C01 as a fermion particle, considers the information amount of the specific product in the community C01 as energy, and distributes the advertisement of the specific product based on the phase diagram. Correspondence, that is, an advertising strategy is determined (step S2).

  For example, the determination device 10 regards each user who belongs to the community C01 as a fermion (step S3). For example, the determination device 10 regards the user U01 and the user U02 as fermions in different states. Subsequently, the determination device 10 identifies the users forming a pair from the users belonging to the community C01, and regards the identified pair as a Bose-condensed fermion particle (step S4). As will be described later, the determination device 10 may hold information distribution, an event, or the like in order to increase the number of users who make a pair. For example, the determination device 10 identifies a pair of users who are a lover or a couple according to various registration information registered in the community server 110 or the like and contents of messages.

  In addition, the determination device 10 identifies users who are predicted to be compatible with each other, that is, users who can be paired, in accordance with various registration information registered in the community server 110 or the like and the contents of messages. Then, the determination device 10 proposes information distribution such as advertisement and event holding so that users who can be paired can be regarded as paired, that is, fermions can be regarded as Bose particles.

  For example, in the BCS theory, as shown in (a) of FIG. As shown in 1 (b), particles having a positive charge are slightly attracted to the electrons having a negative charge. As a result, as shown in (c) of FIG. 1, as a result of the particles having a positive charge being attracted, there is a portion where the density of the positive charges is higher than that of other regions. As a result, as shown in (d) of FIG. 1, other electrons are attracted to the portion where the density of positive charges is high. As a result, the two electrons appear to move as a pair. Here, when an attractive interaction acts on each electron, the BCS theory shows that the electron pair is Bose condensed. When such Bose condensation occurs, the corresponding system will fall into a superconducting state.

  Therefore, the determination device 10 increases the number of users who form a pair within the community C01 by holding an advertisement distribution and an event so that the users who can form a pair form a pair. As a result, the determination device 10 leads the corresponding system to a state closer to the superconducting state.

  Subsequently, the determining apparatus 10 regards the intrusion length of London as the amount of information propagated to the pair (step S5). For example, as shown in FIG. 1 (f), when an external magnetic field is applied to a substance in the normal conduction state, the magnetic force passes through the substance. On the other hand, as shown in (g) of FIG. 1, when the external magnetic field is not applied to the substance in the normal conduction state, no magnetic field is generated.

  Here, as shown in (f) of FIG. 1, a substance to which an external magnetic field is applied is brought into a superconducting state, or, as shown in (g) of FIG. 1, a substance to which an external magnetic field is not applied is in a superconducting state. When the external magnetic field is applied after the setting, the magnetic field is pushed out of the substance to the outside as shown in (h) of FIG. Therefore, the determination device 10 considers the external magnetic field as information of the specific product in the community C01 (for example, considers the magnetic force as the amount of information), and the degree of influence that the information of the specific product has on the paired users. Is regarded as the invader of London.

  Then, the determination device 10 calculates the critical temperature “Tc” that causes the phase transition between the normal state and the superconducting state based on the BCS theory and the gap equation, and generates the phase diagram showing the phase transition in the corresponding system. Yes (step S6). For example, the determination device 10 considers a value based on the number of media accesses and the amount of messages in the community C01 as the energy value and temperature in the community C01 and calculates the critical temperature “Tc” from the gap equation. In addition, the determining apparatus 10 regards the ratio of the number of users who form a pair in the community C01 as the occupancy probability of the electron pair, and the ratio of the number of users who are not a pair as the non-occupancy probability of the electron pair. Rather, the state of the corresponding system is specified from the ground state of the wave function in BCS theory.

  Then, the determining apparatus 10 considers the amount of information in the community C01 as the energy of the corresponding system and selects an advertising strategy (step S7). For example, when the corresponding system is in the normal conduction state at the time of delivering the advertisement, the determining apparatus 10 delivers the advertisement to each individual in the community C01 based on a normal advertising strategy. That is, the determination device 10 delivers the advertisement to each user based on the attribute of each user. On the other hand, when the corresponding system is in the superconducting state, the determining device 10 distributes the advertisement in a state where the effect of the advertisement is highly estimated. That is, the deciding device 10 considers that the advertisement is being propagated to the entire community C01 (that is, the superconducting state) even when a small number of advertisements are delivered, and selects the delivery of the advertisement. Then, the determining apparatus 10 distributes the advertisement to the users of the community C01 in the determined distribution mode (step S8).

[1-7. Example of processing for controlling phase]
Here, in order to further enhance the advertising effect, the determination device 10 may control the state of the community C01 so that the corresponding system is in the superconducting state. For example, as shown in equation (7), the larger the number of users in a pair, the closer the state of the corresponding system becomes to the superconducting state. Therefore, the determination device 10 may execute various kinds of processing such that the number of users in pairs increases. For example, the determination device 10 may provide mutual information to a plurality of users who can be paired among the users belonging to the community C01. Further, the determination device 10 may suggest participation in the event to a plurality of users who can be paired. Further, the determining apparatus 10 may perform various kinds of information distribution and processing such as coupling service so that a plurality of users who can be a pair become a pair.

  Further, when the temperature of the corresponding system is lower than the critical temperature “Tc”, it is predicted that the superconducting state is transited. Therefore, the determining apparatus 10 stops the distribution of the information about the specific product until the temperature of the corresponding system becomes lower than the critical temperature “Tc”, so that the information amount about the specific product in the community C01, that is, the corresponding system. Reduce the energy of. Here, when the user belonging to the community C01 posts a specific product or the like, the determination device 10 may perform processing such that the posting is not shown to other users of the community C01. .. Then, the determination device 10 may perform more effective advertisement distribution by distributing information regarding the specific product after the temperature of the corresponding system becomes lower than the critical temperature “Tc”.

[2. Configuration of determination device]

  Returning to FIG. 2, the description will be continued. In the strategy map database 32, phase information of each community is registered as a strategy map for determining an advertisement distribution mode. For example, FIG. 4 is an example of information registered in the strategy map database according to the embodiment. As shown in FIG. 4, information having items such as “community ID” and “strategy map” is registered in the strategy map database 32.

  Here, the “strategy map” is information indicating in what distribution mode an advertisement should be distributed to the community indicated by the associated “community ID”, and specifically, “community This is information indicating the critical temperature in the corresponding system of the community indicated by "ID". For example, in the example shown in FIG. 4, the community ID “community # 1” and the strategy map “phase diagram # 1” are registered in association with each other. Such information indicates, for example, that the phase diagram of the corresponding system of the community indicated by “community # 1” is “phase diagram # 1”. In the present embodiment, an example in which a “phase diagram” is generated as a strategy map will be described, but the embodiment is not limited to this and may be, for example, a numerical value indicating a critical temperature or the like.

  Returning to FIG. 2, the description will be continued. In the content database 33, the content to be distributed is registered. For example, in the content database 33, data of advertisement content of each specific product is registered as an advertisement distributed to each community C01.

  Returning to FIG. 2, the description will be continued. The control unit 40 is a controller, and various programs stored in a storage device inside the determination device 10 include a RAM and the like by a processor such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit). It is realized by being executed as a work area. The control unit 40 is a controller, and may be realized 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 40 includes an acquisition unit 41, an identification unit 42, a calculation unit 43, a generation unit 44, a determination unit 45, and a provision unit 46.

  The acquisition unit 41 acquires various kinds of information necessary for executing the determination process. More specifically, the acquisition unit 41 acquires the amount of information about the community C01 as a parameter. For example, the acquisition unit 41 acquires, from the community server 110, information about users belonging to the community C01, connection relations between users, information on messages exchanged between users, and the like. Further, the acquisition unit 41 acquires the access history of the users belonging to the community C01 from the media server 120. In addition, the acquisition unit 41 acquires the purchase history of users belonging to the community C01 from the electronic commerce server 130. Then, the acquisition unit 41 registers each acquired information in the community information database 31.

  The identifying unit 42 analyzes various types of information registered in the community information database 31 and acquires various types of information necessary for the determination process. For example, the identifying unit 42 acquires various information used to identify a pair of users, such as the amount of information on a specific product exchanged between users, from the history of messages exchanged within the community C01. To do. Then, the identifying unit 42 identifies the users to be paired among the users belonging to the community C01.

  For example, the specifying unit 42 specifies a user who has been registered in advance as having a marital relationship or a user who has been previously registered as having a lover relationship as a pair of users. In addition, the specifying unit 42 can be considered to be a user who is estimated to have a marital relationship or a lover relationship, that is, a pair based on the history and contents of messages exchanged between users. Identify the person. In addition, the specifying unit 42 may specify a user who is estimated to be able to take a common purchase behavior as a pair of users, in addition to the users who are in a marriage relationship or a lover relationship.

  The calculation unit 43 calculates a value necessary for generating the phase information. For example, the calculation unit 43 specifies the access to the media related to the specific product made by the user belonging to each community from the access history of the user, and acquires the number of specified accesses as a parameter. The calculation unit 43 also acquires the attributes of the users belonging to each community from the user characteristics. In addition, the calculation unit 43 specifies the amount of messages related to a specific product made between users belonging to a certain community, etc. from the communication history. Further, the calculation unit 43 identifies the number of purchases of the specific product by users belonging to a certain community from the purchase history.

  Further, the calculation unit 43 specifies the connection relationship between users in a certain community based on the connection information, and covers the outermost point of the figure or the solid when the specified connection relationship is replaced with the figure or the solid. Among the distances between the manifolds and the distances connecting the outermost points, the longest distance and the like are acquired as parameters indicating the size of the community. That is, the calculation unit 43 acquires various parameters used for fitting the above-mentioned thermodynamics from the information registered in the community information database 31. In addition to the above-mentioned various parameters, the calculation unit 43 acquires the above-mentioned various information (for example, the amount of interest propagation and the amount of media access change).

  Then, the calculation unit 43 calculates the value necessary for generating the phase information. More specifically, the calculation unit 43 calculates a value indicating the state of the corresponding system, such as the value of the temperature “T” in the corresponding system. For example, the calculation unit 43 calculates the value of the temperature of the corresponding system based on the number of media accesses including the number of purchases of the specific product, and calculates the internal energy from the value indicating the degree of potential interest in the specific product. Calculate the value of.

  Based on the value of the temperature “T” in the corresponding system calculated by the calculation unit 43, the value of the internal energy value “U”, the number of particles, etc., the generation unit 44, based on the gap equation and the BCS theory, Calculate the critical temperature "Tc". Then, the generation unit 44 generates a phase diagram indicating the generated critical temperature, and registers the generated phase information in the strategy map database 32 as a strategy map.

  For example, the generation unit 44 regards a value based on the number of accesses to the media related to the specific product in the community C01 as the temperature in the corresponding system corresponding to the community. Further, the generation unit 44 regards the degree of potential interest in a specific product in the community C01 as the internal energy of the corresponding system corresponding to the community C01. Further, the generation unit 44 regards the size of the community C01 as the volume of the corresponding system corresponding to the community. In addition, the generation unit 44 specifies the ratio of the number of users who form a pair, and considers the specified ratio as the ratio of the bose particles in the corresponding system. Further, the generation unit 44 regards the amount of information related to a specific product, which is information transmitted by users belonging to the community, as a generation operator in the corresponding system. Further, the generation unit 44 regards the value indicating the influence of the information on the user as the invasion length of London with respect to the particles forming the corresponding system. Then, the generation unit 44 calculates the critical temperature “Tc” based on the BCS theory.

  The deciding unit 45 regards the users belonging to the community C01 as fermions and the users as the identified pairs as Bose-condensing particles, and determines the phase transition between the superconducting state and the normal conducting state. The mode of providing information to the user is determined based on the indicated phase information. More specifically, the determination unit 45 identifies, based on the phase information of the corresponding system, a distribution mode of information that changes the phase of the corresponding system to a phase in which information is more easily transmitted.

  For example, the determination unit 45 reads the value of the critical temperature “Tc” in the corresponding system of the community C01 as the strategy map from the strategy map database 32. Further, the determining unit 45 considers the value based on the number of accesses to the media related to the specific product in the community C01 as the temperature in the corresponding system corresponding to the community C01, and determines whether the corresponding system is in the normal conduction state or the superconducting state. Determine if it is in a state. Then, the determining unit 45 determines the distribution mode of the advertisement based on whether the state of the community C01 at the time of distributing the advertisement is the normal conduction state or the superconduction state.

  For example, when the state of the community C01 is the normal conduction state, the determining unit 45 causes the phase transition to the superconducting state, and thus stops the distribution of the advertisement so that the information amount of the specific product in the community C01 decreases. You may decide to do so. In addition, the determination unit 45 identifies users who can be paired, and decides to provide a coupling service or propose to participate in an event to the identified users. Note that, for example, when the information is suppressed, the determining unit 45 distributes the advertisement so that the corresponding system changes from the superconducting state to the normal state, thereby suppressing the information such as rumor. So-called fire extinguishing of information may be realized. In this way, the determining apparatus 10 can control the halation risk of information by controlling the distribution mode of the advertisement so as to change the phase of the corresponding system.

  The providing unit 46 provides the advertisement to the community C01 in the determined distribution mode. For example, the providing unit 46 provides the community C01 with the advertisement of the amount determined by the determining unit 45.
