Abstract: The present invention aims to provide a relationship estimation system capable of estimating a relationship of attributes meaningful to a person based on time-series data of attributes relating to a body or activities of a person. The relationship estimation system collects time-series data of attributes relating to a body or activity of a person, calculates similarity between time-series data of the attributes, and generates a relationship graph G in which the attributes are served as nodes, the similarity is served as a link weight, and the nodes are connected by the links. An inter-node having a large total link weight of the inter-node in the relationship graph G is extracted, and the relationship between attribute corresponding to the inter-node is estimated.

A plurality of information terminal devices and a server are connected via in a communicable state via a network. The control unit of each information terminal device controls a transmission unit, based on the importance of elements configuring real space information, the importance being determined by an importance determination unit of the server such that sensor data corresponding to an element configuring the real space information and having high importance is preferentially transmitted. The generation unit of the server uses a feature model to generate real space information, based on elements configuring real space information and having high importance extracted by an extraction unit from the most recent sensor data received by a reception unit.

Abstract: The invention aims to provide a relationship evaluation system capable of effectively evaluating a relationship of a node to a reference node in a relationship graph in which plural nodes are connected by links. A reference point node is selected based on selection information regarding the reference point node input from the selection information input unit. Based on the reference point node, a relationship graph becoming an evaluation target is extracted from the relationship graph database to create a virtual communication network based on the graph. In the virtual communication network, simulation is executed by sequentially propagating a virtual communication packet to adjacent nodes from a reference point node selected by the reference point node selection unit as propagation origin. The relationship of the node to the reference node is evaluated based on the content of the communication packet received at the node as a result of executing the simulation.

Abstract: An object display system for a relationship graph includes an object information reception unit that receives object information from a terminal device. A node conversion unit converts the object information into a corresponding node and sets the node as a reference point node. A relationship graph extraction unit extracts a relationship graph containing the reference point node from a relationship graph database. A node relationship evaluation unit evaluates the relationship of each node to a reference point node by scores of two types of evaluation indexes. An object arrangement unit converts each node into a corresponding object and arranges each object converted from each node while making scores of two types of evaluation indexes by the node relationship evaluation unit that correspond to a two-dimensional coordinate. An object output unit outputs each object to the terminal device.

Abstract: In an information terminal processing device of a first user, after selection of a content on a prescribed experience by the first user, content identification information is output to an information terminal device of a second user B, and various information thereof is transmitted to a server device.
