Module 2: Natural Language Processing for Search

• NLP Fundamentals
  • Learn how natural language processing helps systems interpret user queries and understand textual information.
  • Explore tokenisation, text normalisation, and basic text preprocessing techniques.
• Query Understanding
  • Understand query intent, contextual meaning, synonyms, and variations in user language.
  • Explore techniques for improving search results when queries do not match document wording exactly.

Module 3: Text Processing and Document Preparation

• Enterprise Document Processing
  • Learn how to extract, clean, and organise content from PDFs, text files, reports, and business documents.
  • Understand how to handle duplicate content, formatting inconsistencies, and incomplete text.
• Metadata and Document Organisation
  • Explore metadata tagging, document classification, and content categorisation.
  • Understand how metadata filters can improve search precision and support access to relevant information.

Module 4: Embeddings and Semantic Representations

• Introduction to Text Embeddings
  • Understand how embedding models convert text into numerical representations of meaning.
  • Explore the role of embeddings in semantic similarity and contextual information retrieval.
• Embedding Generation and Selection
  • Learn the basic workflow for generating embeddings from documents and search queries.
  • Understand the factors involved in selecting an embedding model for a specific enterprise search application.

Module 5: Vector Search and Similarity Matching

• Vector Search Fundamentals
  • Understand vector representations, similarity calculations, and nearest-neighbour search concepts.
  • Explore how vector search retrieves content based on semantic relevance rather than exact keyword matches alone.
• Similarity Metrics
  • Learn the purpose of cosine similarity, dot product, and Euclidean distance in vector comparison.
  • Understand how metric selection and embedding characteristics can influence retrieval results.

Module 6: Enterprise Semantic Search Architecture

• Search Pipeline Design
  • Explore document ingestion, preprocessing, embedding generation, indexing, query processing, and result retrieval.
  • Understand how these components work together in an enterprise semantic search workflow.
• System Integration
  • Learn how APIs and application interfaces can connect semantic search capabilities with existing business systems.
  • Examine scalability, performance, data freshness, and maintainability considerations.

Module 7: Search Relevance and Ranking

• Relevance Assessment
  • Understand how to determine whether retrieved documents satisfy a user's information needs.
  • Explore precision, recall, and ranking-based evaluation concepts for assessing search quality.
• Ranking and Retrieval Improvements
  • Learn how metadata filters, query refinement, and reranking techniques can improve result relevance.
  • Understand the trade-offs between retrieval quality, response time, and system complexity.

Module 8: Hybrid Search and Query Optimization

• Keyword and Semantic Search
  • Compare lexical retrieval methods with embedding-based semantic retrieval.
  • Understand how hybrid search combines keyword matching and semantic similarity.
• Query Optimization
  • Explore query expansion, synonym handling, filtering, and alternative query formulations.
  • Learn how to investigate ambiguous queries and improve retrieval consistency.

Module 9: Evaluation, Testing, and Monitoring

• Search Quality Evaluation
  • Understand how to prepare representative queries and relevant-document benchmarks.
  • Learn to interpret metrics such as Precision, Recall, Mean Reciprocal Rank (MRR), and Normalized Discounted Cumulative Gain (NDCG).
• Performance Monitoring
  • Examine retrieval latency, failed queries, relevance issues, and user feedback.
  • Understand how testing and monitoring can help identify search weaknesses and guide continuous improvement.

Module 10: Security, Privacy, and Responsible Search

• Enterprise Data Protection
  • Understand authentication, authorisation, document-level access controls, and secure information retrieval.
  • Explore how to prevent search results from exposing information that users are not authorised to access.
• Privacy and Governance
  • Learn about sensitive data handling, retention policies, audit logging, and responsible use of enterprise information.
  • Understand why security and privacy controls must be incorporated throughout the search lifecycle.

Module 11: Practical Implementation and Integration

• Semantic Search Application Development
  • Build a learning prototype that processes a sample document collection and retrieves relevant content for natural-language queries.
  • Connect document processing, embedding generation, vector retrieval, and result presentation into a basic workflow.
• Testing and Troubleshooting
  • Evaluate search results using representative queries and expected relevant documents.
  • Identify issues involving document quality, embedding selection, query formulation, and retrieval configuration.

Module 12: Capstone Project – Enterprise Knowledge Discovery System

• Project Planning and Design
  • Define a business use case, prepare a sample knowledge repository, and design a suitable semantic search workflow.
  • Document the architecture, data preparation steps, retrieval approach, and security requirements.
• Implementation and Evaluation
  • Develop a prototype that retrieves relevant information from enterprise-style documents.
  • Test retrieval quality, document relevance, and response time, then document findings and improvement opportunities.
• Project Presentation
  • Present the solution architecture, demonstrate search queries, and explain the evaluation results.
  • Submit a project report covering implementation decisions, limitations, security considerations, and potential future enhancements.
