     1. Overview of the Present Disclosure 
     &lt;&lt;1.1. Points of Note in the Present Disclosure&gt;&gt; 
     In recent years, methods of estimating emotions of a user according to biological information acquired from the user have been proposed. In addition, technologies for supplying services based on estimated emotions of the user are known. 
     However, in order to realize highly precise emotion estimation, many instruction signals for associating acquired biological information with emotions of a user at the time of obtaining of the biological information are required. The instruction signals may be, for example, information input by the user. However, in this case, a burden on the user is large and it is difficult to collect a large amount of instruction signals. 
     On the other hand, the user has various emotions and performs various behaviors daily. At this time, the foregoing emotions and behaviors are closely related in many cases. For example, in a case in which a user performs imaging using an imaging device such as a camera, the user is estimated to have an interest in a subject. 
     The present disclosure has been devised focusing on daily behaviors associated with the foregoing emotions. That is, according to the information processing device, the information processing method, and the program according to the present disclosure, a database in which biological information is associated with emotion information of a user when the user performs daily behaviors can be generated by recognizing daily behaviors which can serve as a weak instruction of emotions in advance. 
     In addition, according to the information processing device, the information processing method, and the program according to the present disclosure, emotions of a user can be estimated and various services or functions in accordance with the emotions can be supplied to the user by retrieving the database according to biological information acquired from the user. 
     Hereinafter, in the following description of an embodiment of the present disclosure, advantageous effects achieved from features will be described while exemplifying the features of a configuration of the information processing device realizing the foregoing functions. Note that emotions in the present disclosure may be analyzed as including feelings. That is, the emotions in the present disclosure may include feelings such as delight, anger, sorrow, and pleasure in addition to biological reactions of a user. The emotions according to the embodiment may be various states related to the user estimated from biological information. 
     2. First Embodiment 
     &lt;&lt;2.1. Generation of Biology-Emotion DB&gt;&gt; 
     First, generation of a biology-emotion DB and a system configuration example according to the embodiment will be described. In the information processing method according to the embodiment, it is possible to generate a biology-emotion DB in which emotion information associated with behaviors of a user is associated with biological information acquired when the user performs the behaviors. At this time, in the information processing method according to the embodiment, the foregoing biological information and emotion information can be associated by referring to the behavior-emotion DB registered in advance. 
       FIG. 1A  is an explanatory diagram illustrating generation of a biology-emotion DB and a system configuration example according to the embodiment. Referring to  FIG. 1A , an information processing system according to the embodiment includes an operation device  10 , a wearable terminal  20 , an information processing device  30 , a biology-emotion DB  390 , and a behavior-emotion DB  395 . In addition, the operation device  10 , the wearable terminal  20 , and the information processing device  30  are connected via a network  40  so that mutual communication can be performed. 
     (Operation Device  10 ) 
     In the generation of the biology-emotion DB  390  according to the embodiment, the operation device  10  may be any of various devices recognizing behaviors of a user P 1 . In an example illustrated in  FIG. 1A , the operation device  10  may be any of various imaging devices, a smartphone that has an imaging function, or the like. The operation device  10  has a function of transmitting behavior information related to detected behaviors of the user P 1  to the information processing device  30 . For example, in the example illustrated in  FIG. 1A , the operation device  10  detects that the user P 1  photographs a subject O 1  and transmits the detected information to the information processing device  30 . More specifically, the operation device  10  may detect a behavior related to pressing of a shutter button by the user P 1  and transmit behavior information regarding the behavior to the information processing device  30 . 
     (Wearable Terminal  20 ) 
     The wearable terminal  20  according to the embodiment may be any of various terminals acquiring biological information accompanied by a behavior of the user P 1 . In the example illustrated in  FIG. 1A , the wearable terminal  20  acquires biological information of the user when the user photographs the subject O 1 . Therefore, the wearable terminal  20  may include various sensors acquiring biological information of the user P 1 . In addition, the wearable terminal  20  has a function of transmitting the acquired biological information of the user P 1  to the information processing device  30 . 
     (Information Processing Device  30 ) 
     In the generation of the biology-emotion DB  390  according to the embodiment, the information processing device  30  has a function of generating the biology-emotion DB  390  by associating emotion information acquired from the behavior information of the user P 1  of the operation device  10  with the biological information of the user P 1 . More specifically, the information processing device  30  can retrieve the behavior-emotion DB  395  registered in advance according to the behavior information received from the operation device  10  and acquire the emotion information associated with the behavior information of the user P 1 . In addition, the information processing device  30  can cause the biology-emotion DB  390  to be stored by associating the acquired emotion information with the biological information of the user P 1  received from the wearable terminal  20 . The information processing device  30  according to the embodiment may be any of various information processing terminals that have the foregoing functions. The information processing device  30  according to the embodiment may be, for example, a personal computer (PC), a smartphone, a tablet, or the like. 
     In the example illustrated in  FIG. 1A , the information processing device  30  can receive behavior information related to the user P 1  pressing the shutter button from the operation device  10  and acquire emotion information based on the behavior information from the behavior-emotion DB  395 . At this time, in the foregoing behavior-emotion DB  395 , for example, the pressing of the shutter button may be associated with emotion information related to “interest.” In this way, in the behavior-emotion DB  395  according to the embodiment, a behavior which the user P 1  can perform and an estimated emotion of the user P 1  when the user P 1  performs the behavior may be stored. In the example illustrated in  FIG. 1A , in a case in which the user P 1  takes a picture, the user P 1  is estimated to have “interest” in the subject O 1 . Therefore, the pressing of the shutter button and the emotion information related to “interest” are stored in the behavior-emotion DB  395  in association with each other. Note that the details of the behavior-emotion DB  395  according to the embodiment will be described later. 
     In addition, at this time, the information processing device  30  can cause the emotion information related to “interest” acquired from the behavior-emotion DB  395  and biological information received from the wearable terminal  20  to be stored in the biology-emotion DB  390  in association with each other. That is, the information processing device  30  can generate the biology-emotion DB  390  by associating the emotion information obtained from the behavior information of the user P 1  photographing the subject O 1  with the biological information of the user P 1  acquired at the time of photographing.

The feedback recognition unit  380  can perform control such that the correlation strength between the corresponding biological information and emotion information is weakened according to the fact that the evaluation of the user in regard to the operation of the operation unit  360  is negative. Alternatively, the feedback recognition unit  380  can perform control such that the correlation strength between the corresponding biological information and emotion information is strengthened according to positive evaluation of the user in regard to the operation of the operation unit  360 . 
     For example, in a case in which the control unit  350  controls the operation unit  360  such that the shutter is pushed according to the acquired biological information, the feedback recognition unit  380  can recognize a manipulation by the user on a photographed image. At this time, for example, the feedback recognition unit  380  may perform control such that the correlation strength between the biological information and the emotion information used when the control unit  350  controls the operation unit  360  is weakened according to the fact that the user deletes a photographed image. 
     On the other hand, for example, the feedback recognition unit  380  can also perform control such that the correlation strength between the biological information and the emotion information used when the control unit  350  controls the operation unit  360  is strengthened according to the fact that the user reserves a photographed image. At this time, the feedback recognition unit  380  may strengthen, for example, a weight of a support vector in a model generated using SVM. In addition, for example, the feedback recognition unit  380  can also strengthen a connection weight in a constructed neural network model. 
     In the foregoing function of the feedback recognition unit  380  according to the embodiment, the correlation strength between the biological information and the emotion information can be appropriately corrected in accordance with feedback of the user. Thus, it is possible to realize more highly precise emotion estimation. 
     In addition, the feedback recognition unit  380  may control the correction related to the association between the corresponding behavior information and emotion information according to the feedback from the user. The feedback recognition unit  380  can also perform control such that the association between the corresponding behavior information and emotion information is deleted according to the fact that the evaluation of the user in regard to the operation of the operation unit  360  is negative. 
     For example, the feedback recognition unit  380  can also delete the association between the behavior information and the emotion information used when the control unit  350  controls the operation unit  360  according to the fact that the user deletes photographed images a predetermined number of time or more. 
     In the foregoing function of the feedback recognition unit  380  according to the embodiment, the association between the biological information and the emotion information can be appropriately corrected in accordance with feedback of the user. Thus, it is possible to realize supply of a higher-value service.

     In addition, for example, the behavior recognition unit  330  may recognize that the user laughs or cries by processing sound information acquired by a microphone included in the behavior measurement sensor unit  315  in accordance with the foregoing statistical scheme or machine learning scheme. 
     Subsequently, the control unit  350  of the information processing device  30  acquires the emotion information associated with the behavior information of the user recognized in step S 1103  from the behavior-emotion DB  395  (S 1104 ).
