Probabilistic Duplicate Detection Algorithmic Framework

fuzzy matching duplicate detection probabilistic scoring data quality
Prompt
Design a PostgreSQL implementation of advanced record matching using fuzzy matching techniques and probabilistic scoring. Create a system that can compare records across multiple dimensions, calculating similarity scores using Levenshtein distance, trigram matching, and custom weighted algorithms. Implement a configurable threshold system that can adaptively identify potential duplicates with configurable sensitivity levels.
