Semantic deduplication for large text datasets
Article summary
Quick briefing — cleaned from the original RSS feed
When you build a dataset for ML training or a RAG knowledge base, exact deduplication is not enough. Copy-paste duplicates are easy to catch with a hash. Paraphrases, reformulations, and semantically equivalent sentences are not. Running standard MinHash or Jaccard on them gives near-zero similarity even when they carry identical information. The result: bloated corpora, biased models, and retrieval systems that return the same fact dressed in different words. Semantic deduplication fixes this…
