The recursive character text splitter balances the contradiction between document chunks being too long to exceed the context window and too short to lose semantics by attempting to split at natural boundaries (paragraphs, sentences).

UnverifiedFixed 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.76% similarUnverifiedThe parser restores Markdown heading hierarchy by tracking font sizes, enabling LangChain's text splitter to segment content along semantic boundaries.75% 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.74% similarUnverifiedSemantic chunking typically uses embedding models or dedicated text-splitting models to map text into a vector space and identify semantic boundaries, treating a point as a semantic breakpoint when the vector similarity between adjacent sentences drops noticeably.74% similar
