- Contextual Augmentation: Every chunk is supplemented with sufficient background data to make it comprehensible by itself.
- Discount of Ambiguity: By offering standalone context, the mannequin can precisely interpret every chunk’s relevance with out counting on surrounding data.
Why It’s Good: Enhancing every chunk with extra context minimizes ambiguity and ensures that the mannequin can successfully make the most of every bit of data. This results in extra exact and coherent responses, because the AI can higher discern the importance of every chunk in relation to the question.
Reranking for Optimum Relevance
After retrieving probably the most related chunks, reranking is employed to organize them primarily based on their relevance. This step ensures that the highest-quality data is prioritized, which is particularly essential when coping with token limitations.
Reranking Course of:
- Evaluation of Relevance: Every chunk is evaluated for its relevance to the question.
- Optimum Ordering: Chunks are reordered in order that probably the most pertinent data seems first.
- High quality Assurance: Ensures that probably the most invaluable content material is prioritized, enhancing the general response high quality.
Why It’s Good: Reranking acts as a remaining filter that elevates probably the most related and high-quality chunks to the forefront. This prioritization ensures that the mannequin focuses on probably the most essential data, maximizing the effectiveness of the response even inside token constraints.
Synergy at Work: How Contextual RAG Transforms AI Retrieval
The true genius of Contextual RAG lies in how these 4 improvements interconnect and amplify one another. Individually, every enhancement gives vital enhancements, however their mixed impact creates a extremely optimized retrieval pipeline.

Step 6: Course of the Doc and Get Chunk Size
This code takes a doc and breaks it into smaller items, creating two variations of those items: one which retains every half precisely as it’s within the unique (referred to as original_chunks) and one other the place every half has been processed so as to add further context or formatting (referred to as contextualized_chunks). It then counts what number of items are within the contextualized_chunks listing to see what number of sections have been created with added context. Lastly, it prints out the primary piece from the original_chunks listing to indicate what the primary a part of the doc appears to be like like in its unaltered kind.
# Course of the doc
original_chunks, contextualized_chunks = cr.process_document(doc)
len(contextualized_chunks)
print(original_chunks[0])
Step 7: Print Particular Chunks
Mix the top-ranked chunks right into a coherent context string and generate an in depth response utilizing the GPT-4o mannequin.
print(contextualized_chunks[0])
print(original_chunks[10])
print(contextualized_chunks[10])
On this code:
- print(contextualized_chunks[0]): This prints the primary chunk of the doc that features added context. It’s helpful to see how the very first part of the doc takes care of processing.
- print(original_chunks[10]): This prints the eleventh chunk (index 10) from the unique, unmodified model of the doc. This provides a snapshot of what the doc appears to be like like in its uncooked kind at this place.
- print(contextualized_chunks[10]): It prints the eleventh chunk (index 10) of the doc from the contextualized model, enabling you to match how including context modified the unique content material.
Step 8: Creating Search Indexes
This step entails creating search indexes for each the unique and context-enhanced chunks of the doc, making it simpler to go looking and retrieve related data from these chunks:
Vectorstore creation
- The `create_vectorstores()` technique converts the doc chunks into numerical representations (vectors), which can be utilized for semantic search. This permits for looking primarily based on which means reasonably than actual key phrases.
- `original_vectorstore` holds the vectors for the unique chunks, and `contextualized_vectorstore` holds the vectors for the context-enhanced chunks.
BM25 index creation
- The `create_bm25_index()` technique creates an index primarily based on the BM25 algorithm, which is a typical solution to rank chunks of textual content primarily based on key phrase matching and relevance.
- `original_bm25_index` holds the BM25 index for the unique chunks, and `contextualized_bm25_index` holds the BM25 index for the context-enhanced chunks.
This step prepares each forms of search techniques (vector-based and BM25-based) to effectively search and retrieve data from the 2 variations of the doc (unique and contextualized). It enhances the flexibility to carry out each semantic searches (primarily based on which means) and keyword-based searches.
# Create vectorstores
original_vectorstore = cr.create_vectorstores(original_chunks)
contextualized_vectorstore = cr.create_vectorstores(contextualized_chunks)
# Create BM25 indexes
original_bm25_index = cr.create_bm25_index(original_chunks)
contextualized_bm25_index = cr.create_bm25_index(contextualized_chunks)Step 9: Generate a Distinctive cache key
This step generates a singular cache key for the doc to effectively observe and retailer its processed information, stopping the necessity to re-process it later. It additionally prints out the variety of chunks the doc was divided into and shows the generated cache key, serving to to substantiate the doc’s processing and caching standing. That is helpful for optimizing doc retrieval and managing processed information effectively.
