Information Providing Device Using Leader Points for Group Influence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information providing systems fail to accurately consider the influence of users within a group when providing information, as they do not account for the varying levels of influence among group members, leading to biased decision-making and inaccurate information delivery.
Innovation Solution
An information providing device that forms groups based on position information and calculates a 'leader point' for each user, indicating their influence within the group, by analyzing time series data of position information to determine the degree of match with specific action patterns, and uses these points to select and transmit relevant information.

Engineering Contradiction Analysis
1Adaptability or versatility
If information is provided based on common preference of all group members, then information coverage is improved, but decision-making accuracy deteriorates because it does not reflect the influence of specific leaders
Solution Approach 1:
The patent applies local quality by differentiating the weight of preference information based on each user's leader point. Instead of treating all group members equally, the system assigns different weights to preference information from different users, where users with higher leader points (indicating greater influence) have their preferences weighted more heavily. This resolves the contradiction by maintaining comprehensive coverage of all group members' preferences while accurately reflecting the decision-making dynamics through differential weighting.
Solution Approach 2:
The patent changes the parameter of preference information weighting from a uniform value to a variable value based on leader points. The system dynamically adjusts the weight given to each user's preference information according to their calculated leader point, which reflects their influence in the group. This parameter change enables the system to simultaneously consider all group members' preferences while prioritizing those with greater influence, thus resolving the contradiction between coverage and accuracy.
2Measurement precision
If position information of multiple users is collected and grouped, then group identification is improved, but calculation complexity increases due to analyzing time series data and determining leader points
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing leader points for each user based on their historical position information and action patterns. Instead of performing complex calculations for every grouping operation, the system pre-processes the data to establish user influence metrics in advance. This reduces the computational burden during actual grouping operations while maintaining high identification accuracy, thus resolving the contradiction between precision and complexity.
Solution Approach 2:
The system implements self-service by having terminal devices automatically transmit their own position information and by having the system automatically calculate leader points and perform grouping without requiring manual intervention. This automation reduces the operational complexity for users while maintaining high group identification accuracy through systematic data processing.

AI summary
A group forming unit acquires position information of a subject that is a user or a terminal device, and forms a group including a plurality of subjects on the basis of time series data of the position information pertaining to the plurality of subjects. A point calculator calculates, on the basis of the time series data of the position information, a characteristic action amount indicating the degree of being matched with a predetermined action pattern in which influence of a subject in the group is high, for each of the plurality of subjects included in the group formed in the group forming unit, and calculates a point for each of the subjects on the basis of the characteristic action amount. An item selector selects an item to be presented to the group such that a subject having a high point calculated in the point calculator is prioritized.
