UnverifiedFixed-character chunking strategies truncate sentences and disrupt semantic integrity, and should be replaced with intelligent semantic chunking or sliding window strategies.70% similarUnverifiedCharacter-count-based chunking (e.g., every 300 characters) is simple but prone to breaking semantic coherence.68% similarUnverified文本块重叠处理可在关键知识点跨越切分边界时保留语义连贯性，例如chunk_size=500、chunk_overlap=5067% similarUnverifiedSplitting documents into chunks by a fixed character count destroys semantic integrity; intelligent semantic chunking or a sliding window strategy can ensure that each document chunk contains complete semantic information.65% similarUnverifiedRecursive character chunking is LangChain's default approach, which sequentially attempts to split at hierarchical boundaries such as paragraphs, sentences, and words in order to prioritize semantic integrity.65% similar
