AI0-001 Implementing AI Solutions Practice Question
A team is implementing a RAG system for a large legal document repository. They need to chunk the documents for efficient retrieval. The documents contain long sections with subsections, and the team wants to preserve the hierarchical structure. Which chunking strategy is MOST appropriate?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Hierarchical chunking that preserves section and subsection boundaries
Hierarchical chunking preserves the document structure by maintaining parent-child relationships, which is crucial for legal documents where context from headings matters. Fixed-size may break logical sections; semantic chunking splits by topic but loses hierarchy; overlapping chunks help continuity but don't preserve structure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Hierarchical chunking that preserves section and subsection boundaries
Why this is correct
Hierarchical chunking maintains the document's structure, allowing retrieval of relevant subsections along with their parent context, essential for legal documents.
- ✗
Overlapping chunking with a 10% token overlap
Why it's wrong here
Overlapping chunks help with continuity but do not preserve hierarchical structure; they are often used with fixed-size chunking.
- ✗
Semantic chunking based on topic segmentation
Why it's wrong here
Semantic chunking groups related content but does not inherently preserve hierarchical relationships like sections and subsections.
- ✗
Fixed-size chunking with 512 tokens per chunk
Why it's wrong here
Fixed-size chunking ignores document structure, potentially splitting sections in the middle and losing context.
