Posted Information Verification Using Event Influence Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to accurately verify the reliability of posted information, especially for events with wide geographical or temporal influences, such as disasters, due to discrepancies between the location and time of the event in the posted information and high-reliability sources.
Innovation Solution
An information verification program that calculates reliability levels by comparing posted information with high-reliability sources, using geographical and temporal influence ranges specified from metadata and hazard maps to assess the accuracy of the posted content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the reliability verification method compares posted information with high-reliability information sources, then the accuracy of reliability assessment is improved, but the method fails to account for events with wide geographical or temporal influences causing false negatives
Solution Approach 1:
The patent transitions from point-based location verification to area-based influence range verification. Instead of checking whether posted location exactly matches high-reliability source location, the system defines geographical influence ranges (areas) and temporal influence ranges (time periods) around event locations, then verifies whether posted information falls within these expanded dimensional boundaries. This resolves the contradiction by maintaining precise verification while accommodating wide-influence events through spatial and temporal dimension expansion.
Solution Approach 2:
The patent changes the verification parameters from exact location and time matching to range-based matching. By introducing geographical influence range parameters (latitude/longitude boundaries) and temporal influence range parameters (time windows), the system allows posted information to be verified as reliable even when locations and times differ slightly from high-reliability sources, as long as they fall within the defined influence ranges. This parameter transformation maintains verification rigor while adapting to events with broad spatial-temporal impacts.
2Measurement precision
If the verification system uses exact location and time matching with high-reliability sources, then the measurement precision is improved, but the complexity of the verification system increases due to need for influence range calculation
Solution Approach 1:
The patent performs preliminary actions by pre-calculating and storing geographical influence ranges and temporal influence ranges for events from high-reliability information sources before verification occurs. These pre-computed influence ranges are stored as reference data, so when posted information needs verification, the system only needs to check whether the posted location and time fall within the pre-defined ranges, rather than performing complex calculations in real-time. This reduces verification system complexity while maintaining precise location and time verification.
3Reliability
If the system verifies posted information by comparing with high-reliability sources, then the reliability of information is improved, but the loss of information occurs when posted information falls outside the exact match criteria despite being accurate
Solution Approach 1:
The patent expands verification from exact point matching to range-based matching by introducing geographical influence ranges and temporal influence ranges. Posted information is verified as reliable if it falls within these expanded dimensional boundaries, even if exact location and time don't match high-reliability sources. This prevents loss of valid posted information while maintaining high reliability standards through range-based verification.
Solution Approach 2:
The patent transforms verification parameters from exact matching requirements to range-based acceptance criteria. By defining geographical influence ranges (spatial parameters) and temporal influence ranges (temporal parameters), the system accepts posted information as reliable when it falls within these ranges, rather than requiring exact matches. This parameter change reduces information loss while preserving reliability through boundary-defined verification.

AI summary
A computer-readable recording medium stores an information verification program for causing a computer to execute a process. The process includes: acquiring posted information that includes first information which is text information, second information which is at least one of image information and audio information, and metadata of the second information; specifying an event that occurs, based on the first information; specifying an influence range that indicates a range of at least one of a geographical influence and a temporal influence by the event; and calculating a first reliability level of the posted information based on the influence range and the metadata.
