Publication number: 20230260646Abstract: 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.Type: ApplicationFiled: June 17, 2021Publication date: August 17, 2023Applicants: KYOTO UNIVERSITY, VELDT INC.Inventors: Ryoichi SHINKUMA, Jin NONOGAMI

Publication number: 20210350261Abstract: A learning-type real space information generation system uses sensor data that can be efficiently uploaded from an information terminal device to a server, and which is capable of generating highly accurate real space information. 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.Type: ApplicationFiled: October 2, 2019Publication date: November 11, 2021Applicant: KYOTO UNIVERSITYInventor: Ryoichi SHINKUMA

Patent number: 10489429Abstract: 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.Type: GrantFiled: February 17, 2015Date of Patent: November 26, 2019Assignees: Kyoto University, Kobe Digital Labo Inc.Inventors: Ryoichi Shinkuma, Kazuhiro Yamaguchi

Patent number: 10366125Abstract: 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.Type: GrantFiled: February 13, 2015Date of Patent: July 30, 2019Assignee: KYOTO UNIVERSITYInventor: Ryoichi Shinkuma

Patent number: 10165019Abstract: 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. In an information terminal device of a second user B, after the content identification information is input, a unique key corresponding to the content identification information is generated. Information on the input date and time and/or the input location of the content identification information is transmitted to the server device. In the server device, after collating unique keys, the input date and time and/or the input location of the content identification information are defined as a shared date and time and/or a shared location of the content, and the shared experience information is constructed to make a database thereof.Type: GrantFiled: June 18, 2015Date of Patent: December 25, 2018Assignee: Kyoto UniversityInventor: Ryoichi Shinkuma
