The fixed-size chunking strategy splits by N characters (or tokens), retaining an overlap of M characters between adjacent chunks, without awareness of structure, sentences, or semantics.

UnverifiedSegmented generation should be split along business semantic boundaries rather than hard-cut by character count, otherwise the structural consistency of the concatenated result is difficult to guarantee.70% 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.69% similarUnverifiedFixed word-count splitting may hard-cut in the middle of a sentence and disrupt semantics, so an overlap mechanism is commonly introduced (e.g., 500 characters per segment with 100 characters of overlap between adjacent segments) to preserve cross-segment information.68% similarUnverifiedFixed-size chunking breaks semantic integrity, while paragraph- or semantic-boundary-based chunking requires more complex parsing logic.67% similarUnverifiedM-plicits unifies multiple levels of detail into a single representation, organized into a hierarchical structure through nested residuals, enabling controllable noise/detail trade-offs.67% similar
