LangChain - Text Splitting
Given this code snippet using langchain semantic chunking: 
chunker = SemanticChunker(chunk_size=100, chunk_overlap=20)
chunks = chunker.chunk_text('This is a simple test sentence to check chunking behavior.')
What will be the approximate number of chunks generated?
A3 chunks
B2 chunks
C1 chunk
D4 chunks
Step-by-Step Solution
Solution:

  1. Step 1: Estimate text length

    The text is short, less than 100 characters, so fits in one chunk.

  2. Step 2: Consider chunk size and overlap

    Chunk size 100 is larger than text length, so only one chunk is created.

  3. Final Answer:

    1 chunk -> Option C

  4. Quick Check:

    Short text fits in one chunk [OK]
Quick Trick: If text length < chunk_size, only one chunk is created [OK]
Common Mistakes:
  • Assuming overlap creates multiple chunks regardless of text length
  • Overestimating number of chunks for short text
  • Ignoring chunk size parameter
