  • Monitoring and evaluation
  • Security considerations

What Is Retrieval-Augmented Generation (RAG)?

RAG is an AI architecture that combines:

  1. Information retrieval
  2. Context augmentation
  3. Generative AI

Instead of relying only on model training data, RAG retrieves relevant information from external sources and injects it into prompts.

Why RAG Matters

RAG improves:

  • Accuracy
  • Grounding
  • Freshness of information
  • Enterprise knowledge integration
  • Explainability

Common RAG Use Cases

Typical RAG applications include:

  • Embedding model
  • Vector database or search index
  • Retrieval engine
  • Large language model
  • Prompt orchestration layer

RAG Workflow Overview

The general workflow is:

  1. Ingest data
  2. Split data into chunks
  3. Generate embeddings
  4. Store embeddings in an index
  5. Receive user query
  6. Convert query to embeddings
  7. Retrieve relevant chunks
  8. Add retrieved context to prompt
  9. Generate grounded response

What Are Embeddings?

Embeddings are numerical vector representations of data.

Embeddings capture:

  • Semantic meaning
  • Contextual similarity
  • Relationships between concepts

Embedding Models

Embedding models convert:

  • Text

  • Smaller chunks improve retrieval precision
  • Large documents are difficult to process efficiently

Chunking Strategies

Common chunking methods include:

  • Fixed-size chunking
  • Sliding window chunking
  • Semantic chunking
  • Paragraph-based chunking

Fixed-Size Chunking

Documents are split into equal-sized chunks.

Advantages:

  • Simple
  • Predictable

Disadvantages:

  • May break context unexpectedly

Sliding Window Chunking

Chunks overlap partially.

Benefits include:

  • Better context preservation
  • Improved retrieval continuity

Semantic Chunking

Semantic chunking groups logically related content.

Advantages:

  • Better contextual integrity
  • Higher retrieval quality

Metadata in RAG Systems

Metadata may include:

  • Document title
  • Author
  • Date
  • Category
  • Security labels

Metadata improves filtering and retrieval.

Indexing in RAG Systems

Indexes store:

  • Embeddings
  • Metadata
  • Searchable content

Indexes enable efficient retrieval.

Vector Databases and Search Indexes

RAG systems commonly use:

  • Azure AI Search
  • Vector indexes
  • Hybrid search systems

Semantic Search

Semantic search improves relevance using:

  • Meaning
  • Intent
  • Natural language understanding

Hybrid Search

Hybrid search combines:

  • Keyword search
  • Semantic ranking
  • Vector similarity search

This often improves retrieval quality.

Retrieval Pipelines

Retrieval pipelines:

  • Process user queries
  • Retrieve relevant information
  • Rank search results
  • Filter irrelevant content

Query Embeddings

User queries are converted into embeddings.

The query vector is compared against stored vectors.

Similarity Metrics

Common similarity calculations include:

  • Cosine similarity
  • Euclidean distance
  • Dot product similarity

Top-K Retrieval

Top-K retrieval returns the most relevant results.

Choosing the right K value is important:

  • Too few results may miss context
  • Too many results may add noise

Prompt Augmentation

Retrieved content is inserted into prompts.

This process is called:

  • Prompt grounding
  • Context injection
  • Prompt augmentation

Grounded Responses

Grounded responses:

  • Reference trusted data
  • Reduce hallucinations
  • Improve reliability
