Database Record Error Checking via Label Likelihood Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-tenant database systems, maintaining the accuracy of crowd-sourced data is challenging due to common data entry errors, such as mislabeling or permutation of data fields, which can lead to inaccuracies in database records.
Innovation Solution
Implementing an error checking routine that compares selected database records against the entire database to determine the likelihood of correct label assignments by calculating the ratio of occurrences of entities with specific labels, flagging records with low likelihood for potential errors and allowing for correction actions.

Engineering Contradiction Analysis
1Quantity of substance
If crowd-sourced data entry is used to populate database records, then data coverage and quantity are improved, but data accuracy deteriorates due to common data entry errors
Solution Approach 1:
The system implements a feedback mechanism where database records are automatically checked against predefined criteria and patterns. When errors are detected (such as misplaced first/last names or incorrect formatting), the system generates feedback signals that trigger automatic correction routines, thereby maintaining data accuracy while preserving the benefits of crowd-sourced data entry
Solution Approach 2:
The error checking and correction system operates autonomously without requiring manual intervention. The database automatically identifies errors using predefined rules and patterns, performs corrections self-service style, and maintains data integrity through automated processes that run continuously in the background
2Manufacturing precision
If automated error checking is implemented to improve data accuracy, then data quality is improved, but system complexity increases
Solution Approach 1:
The system uses template-based validation where predefined patterns and criteria are copied and applied to multiple database records. Instead of creating complex custom validation logic for each record type, the system replicates proven error-checking templates across different data sets, reducing system complexity while maintaining high data quality
Solution Approach 2:
The error checking system operates by adjusting and comparing parameters against predefined thresholds and patterns. Rather than implementing complex structural changes to the database architecture, the system modifies validation parameters and criteria to detect and correct errors, thereby improving data quality through parameter optimization rather than structural complexity

AI summary
An error checking technique for database records. A record is selected and its entities are compared with the entities of other records stored in the database to determine a likelihood that the labels associated with the entities of the selected record are correct. The likelihood for each entity of the selected record being correctly labeled can be determined by comparing the number of times that the entity appears in the database records with that label to the number of times that the entity appears in the database records with any other label. If the likelihood does not exceed a threshold, then an error is likely, and action can be taken to correct the record.
