Probabilistic Duplicate Record Matching Algorithm

fuzzy matching duplicate detection data quality
Prompt
Implement a sophisticated SQL-based algorithm for fuzzy matching and identifying potential duplicate records using Levenshtein distance, phonetic matching, and configurable similarity thresholds. Create a solution that can handle multiple data types, configure matching weights, and provide a confidence score for potential duplicates. Include support for handling special characters and multilingual scenarios.
