LangChain - Text Splitting
Which syntax correctly preserves metadata when splitting documents using Langchain's RecursiveCharacterTextSplitter?
Asplitter = RecursiveCharacterTextSplitter(chunk_size=1000, chunk_overlap=100, keep_metadata=True)
Bsplitter = RecursiveCharacterTextSplitter(chunk_size=1000, chunk_overlap=100)
Csplitter = RecursiveCharacterTextSplitter(chunk_size=1000, preserve_metadata=False)
Dsplitter = RecursiveCharacterTextSplitter(chunk_size=1000, chunk_overlap=100, metadata=False)
Step-by-Step Solution
Solution:

  1. Step 1: Check Langchain's RecursiveCharacterTextSplitter parameters

    The splitter does not have a 'keep_metadata' or 'metadata' parameter; metadata is preserved by default in the document objects.

  2. Step 2: Identify the correct syntax without invalid parameters

    splitter = RecursiveCharacterTextSplitter(chunk_size=1000, chunk_overlap=100) uses valid parameters chunk_size and chunk_overlap without unsupported flags.

  3. Final Answer:

    splitter = RecursiveCharacterTextSplitter(chunk_size=1000, chunk_overlap=100) -> Option B

  4. Quick Check:

    Valid splitter syntax = splitter = RecursiveCharacterTextSplitter(chunk_size=1000, chunk_overlap=100) [OK]
Quick Trick: Use only supported parameters; metadata preserved by default [OK]
Common Mistakes:
  • Adding unsupported 'keep_metadata' parameter
  • Using 'metadata' parameter incorrectly
  • Assuming metadata must be explicitly enabled
