It is impossible to change tastes and preferences with a robot or artificial intelligence. Provided is an emotion control system comprising an information acquiring section that acquires network content acquired from a public network; a storage section that stores effect information indicating an effect exerted on an emotion of a control target by the network content; an updating section that updates the effect information stored in the storage section, based on sensor information detected by a sensor of the control target; and an emotion control section that controls the emotion of the control target based on the network content acquired by the information acquiring section and the effect information stored in the storage section.
Please help me write a proper abstract based on the patent claims. CLAIM: 1. An emotion control system comprising: an information acquiring section that acquires network content acquired from a public network; a storage section that stores effect information indicating an effect exerted on an emotion of a control target by the network content; an updating section that updates the effect information stored in the storage section, based on sensor information detected by a sensor of the control target; and an emotion control section that controls the emotion of the control target based on the network content acquired by the information acquiring section and the effect information stored in the storage section. 2. The emotion control system according to claim 1, further comprising: an extracting section that analyzes characters included in the network content acquired by the information acquiring section and extracts meaning content from the network content, wherein the effect information indicates whether the meaning content of the network content is preferable for the control target, and the emotion control section controls the emotion of the control target based on the meaning content of the network content extracted by the extracting section and the effect information stored in the storage section. 3. The emotion control system according to claim 2, further comprising: a judging section that judges whether the meaning content of the network content extracted by the information acquiring section corresponds to a predetermined restricted topic, wherein if the judging section judges that the meaning content of the network content extracted by the extracting section corresponds to the predetermined restricted topic, the emotion control section lowers a degree by which the network content acquired by the information acquiring section affects the emotion of the control target. 4. The emotion control system according to claim 1, wherein the emotion control section determines a parameter indicating the emotion of the control target using a neural network, based on the network content acquired by the information acquiring section and the effect information stored in the storage section. 5. The emotion control system according to claim 4, wherein P1 a plurality of artificial neurons forming the neural network include a plurality of emotion artificial neurons that are artificial neurons for which a current emotion of the control target is defined. 6. The emotion control system according to claim 4, wherein a plurality of artificial neurons forming the neural network include an endocrine artificial neuron that is an artificial neuron for which a generation state of an endocrine substance is defined, and the emotion control section, based on a state of the endocrine artificial neuron and effect definition information, in which is determined an effect that the state of the endocrine artificial neuron has on a parameter of at least one of another artificial neuron and an artificial synapse, updates the parameter of the at least one of the other artificial neuron and the artificial synapse. 7. The emotion control system according to claim 6, wherein the updating section updates the effect information, such that meaning content indicated by the sensor information detected by the sensor affects the emotion corresponding to the endocrine artificial neuron in an active state when the sensor information is detected. 8. The emotion control system according to claim 1, further comprising: a meaning identifying section that identifies meaning content of words exchanged between the control target and a person who is preferred by the control target, based on the sensor information, wherein the updating section updates the effect information such that the content indicating the meaning content identified by the meaning identifying section affects a positive emotion. 9. The emotion control system according to claim 1, wherein the emotion control system is implemented in a server connected in a communicable manner to the control target via a communication network. 10. A system comprising: the emotion control system according to claim 9; and the control target. 11. A computer-readable medium storing thereon a program that, when executed by a computer, causes the computer to: acquire network content acquired from a public network; store effect information indicating an effect exerted on an emotion of a control target by the network content update the stored effect information, based on sensor information detected by a sensor of the control target and control the emotion of the control target based on the acquired network content and the effect information.
