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 6: Process the Document and Get Chunk Length
output :
 Anthropic’s Contextual RAG

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])
Step 7: Print Specific Chunks : Anthropic’s Contextual RAG

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.

# Generate cache key for the doc
cache_key = cr.generate_cache_key(doc)
cache_key
print(f"Processed {len(original_chunks)} chunks")
print(f"Cache key for the doc: {cache_key}")
