Entity Resolution and Deduplication Strategies

Entity resolution strategies: String Similarity (Levenshtein, Jaro-Winkler for name matching), Embedding Similarity (cosine similarity for semantically equivalent entities), LLM-Based Resolution (most accurate but expensive), and Hybrid Approach (filter with string similarity, verify with embeddings, confirm with LLM). Best practices: Run after initial graph construction, merge duplicates, maintain resolution log, re-run periodically.
