Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face challenges in creating high-quality metadata from noisy sources, leading to inaccuracies and inconsistencies in metadata associated with content items.
Innovation Solution
A system and method that utilize quality metrics to evaluate and combine metadata from multiple sources, employing embedding and logistic regression models to determine authoritative metadata and images, ensuring completeness and accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If metadata is collected from multiple noisy sources, then the quantity of metadata increases, but the accuracy and reliability of metadata deteriorates
Solution Approach 1:
The patent segments the metadata evaluation process into multiple independent quality metrics (completeness metric, accuracy metric, consistency metric, reliability metric). Each metric evaluates a specific aspect of metadata quality separately, allowing the system to process and weigh different quality dimensions independently before generating the final quality score.
Solution Approach 2:
The patent introduces an intermediary processing layer that receives metadata from multiple noisy sources and applies quality metrics as filters and evaluators. This intermediary layer computes quality scores and uses weighting mechanisms to mediate between conflicting metadata sources, producing a final authoritative metadata set that reconciles the quantity-input versus accuracy-output contradiction.
2Measurement precision
If quality metrics are computed for each metadata attribute, then the accuracy of metadata improves, but the computational complexity increases
Solution Approach 1:
The patent divides the quality assessment into segmented metrics (completeness, accuracy, consistency, reliability) that can be computed independently for different metadata attributes. This segmentation allows the system to apply appropriate evaluation methods to each attribute type without requiring a single complex universal evaluator.
Solution Approach 2:
The patent changes the parameter representation by computing quality metrics at multiple levels: individual attribute level, metadata record level, and source level. This hierarchical parameter transformation allows the system to manage complexity by aggregating detailed attribute-level assessments into higher-level summaries, reducing the overall computational burden while maintaining precision.
3Reliability
If multiple quality metrics are determined for each metadata, then the reliability of final metadata improves, but the processing time increases
Solution Approach 1:
The patent performs preliminary quality metric computations at the source level before final metadata aggregation. By pre-evaluating the reliability and quality characteristics of each metadata source in advance, the system can weight and prioritize metadata from different sources more efficiently during the final consolidation stage, reducing the time required for comprehensive multi-metric evaluation.
Solution Approach 2:
The patent implements a filtering mechanism that discards low-quality metadata records that fail to meet minimum quality thresholds across the multiple metrics. By eliminating obviously poor-quality data early in the process, the system recovers processing time that would otherwise be spent evaluating and reconciling unreliable metadata, while still maintaining high reliability in the final output through the remaining quality-assured records.
Data Source
AI summary
Disclosed herein are system, apparatus, device, method and/or computer program product aspects, and/or combinations and sub-combinations thereof, for creating high quality metadata and/or images for content. An example aspect operates by a computer-implemented method including receiving, from a plurality of sources, a set of metadata associated with an item of content. The method further includes determining a first quality metric for each metadata of the set of metadata, determining a set of quality metrics for attributes of each metadata of the set of metadata, and determining a second quality metric for each metadata of the set of metadata based on the set of quality metrics. The method further includes generating a final metadata based at least on the set of metadata, the first quality metric, and the second quality metric and providing the item of content and the final metadata associated with the item of content.
