Information Processing Apparatus Search Scoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing information processing apparatuses for surveillance, as described in Patent Literature 1, may include individuals in search results who do not clearly satisfy the designated certainty factors for attributes like hair color or clothing color, leading to inaccuracies in identifying the target person.
Innovation Solution
An information processing apparatus that manages objects, attributes, and certainty factors, calculates a score indicating the matching degree of an object with a search condition using certainty factors and attribute similarities, and displays objects based on these calculated scores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a certainty factor threshold is used to filter search results, then the number of displayed results is reduced, but the accuracy of identifying the target person deteriorates
Solution Approach 1:
The patent transforms the binary certainty factor thresholding approach into a continuous scoring system. Instead of simply filtering results above a fixed threshold (e.g., 90%), the system calculates composite scores by combining certainty factors across multiple attributes (gender, hair color, clothing color, etc.) with their respective weights. This parameter change allows for nuanced ranking of candidates while maintaining flexibility in setting display quantities, thereby resolving the contradiction between reducing result quantity and maintaining identification accuracy.
2Measurement precision
If multiple attributes with certainty factors are used for searching, then the search specificity is improved, but the risk of excluding the target person increases
Solution Approach 1:
The patent implements a weighted scoring system that allows partial matching across multiple attributes rather than requiring all attributes to meet strict thresholds. Each attribute contributes partially to the overall score based on its certainty factor and weight, enabling the system to identify candidates who partially match the search criteria. This approach prevents the exclusion of the target person who may not perfectly satisfy all attribute thresholds, while still maintaining search specificity through the cumulative scoring mechanism.

AI summary
An information processing apparatus capable of improving accuracy of search results. The information processing apparatus includes: a management unit that manages at least one object, an attribute by which the object is classified, and a certainty factor indicating a probability that the object has the attribute in association with each other; a calculation unit that, using a certainty factor of an attribute designated as a search condition and a certainty factor being managed in association with an attribute identical or similar to the attribute designated as the search condition, calculates a score indicating a matching degree of the object with the search condition; and a display unit that displays the object based on the calculated score.
