AI0-001 Implementing AI Solutions Practice Question
A developer is implementing a RAG system for legal document review. The documents are long (50-100 pages) with dense sections. They need to chunk the documents in a way that preserves semantic coherence while keeping chunks small enough for effective retrieval. 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
✓
Semantic chunking based on paragraph and section boundaries
Semantic chunking splits text at natural boundaries (e.g., paragraphs, sections) while ensuring each chunk is coherent, which is crucial for legal documents where meaning can span multiple sentences.
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 with parent-child relationships
Why it's wrong here
Hierarchical chunking with parent-child relationships preserves document structure but fails here because the dense, lengthy legal sections (50–100 pages) require each chunk to remain small for retrieval precision; parent chunks often remain too large, defeating the goal. It is tempting because it excels in scenarios where preserving document hierarchy (e.g., chapters, clauses) is critical, such as summarising multi-section contracts.
- ✗
Fixed-size chunking with 512 tokens and no overlap
Why it's wrong here
Fixed-size chunks may break in the middle of a legal clause, losing context and semantic meaning.
- ✓
Semantic chunking based on paragraph and section boundaries
Why this is correct
Semantic chunking preserves the natural units of legal text, maintaining coherence and improving retrieval quality.
- ✗
Chunking by a fixed number of sentences without considering content
Why it's wrong here
Sentence-based chunking may still split logical sections and is inferior to semantic boundaries for dense legal text.
