Our RAG development approach for Denver builds systems that retrieve accurately from specialized document repositories and generate trustworthy, cited answers. Phase 1 — Document Analysis (2-3 weeks): understanding the knowledge base: corpus audit (cataloguing: the documents that the RAG system will cover — for aerospace: document types (specs, test reports, ICDs, standards), total volume (page count, file count, format distribution), document structure (sections, tables, figures, cross-references), and: access controls (classification levels, need-to-know restrictions) — for cannabis: regulatory document hierarchy (statutes, rules, guidance, enforcement), update frequency, and: cross-reference patterns — the corpus audit determines: the chunking strategy, embedding model requirements, and: retrieval architecture), document quality assessment (evaluating: document quality for: RAG ingestion — OCR quality for: scanned documents (common in: legacy aerospace archives), formatting consistency, metadata completeness, and: version control (ensuring: the RAG system uses: current versions rather than: superseded documents) — poor document quality degrades: retrieval accuracy — we identify and: remediate: quality issues before: building: the RAG pipeline), and information need analysis (understanding: what questions users will ask and: what answers they need — for aerospace engineers: highly specific technical questions with: exact numerical answers cited to: specific document revisions — for cannabis compliance: operational questions requiring: regulatory interpretation with: rule citations — for energy regulatory: precedent research questions requiring: comprehensive coverage across: multiple proceedings — the information needs determine: the retrieval strategy, generation prompts, and: answer format)). Phase 2 — RAG Architecture (2-4 weeks): designing the retrieval and generation pipeline: chunking strategy (how documents are: divided into: retrievable units — naive chunking (splitting by: fixed character or: token count) fails for: technical and: regulatory documents because: it splits: related information across: chunks and: loses: document structure — our chunking strategy preserves: document structure: section-aware chunking (chunks align with: document sections and: subsections), table preservation (tables are: kept intact as: chunks rather than: split across: rows), cross-reference annotation (when: a chunk references: another section, the reference is: annotated with: metadata enabling: the retrieval system to: fetch: both the referencing chunk and: the referenced chunk), and: metadata enrichment (each chunk carries: metadata: document title, document type, section hierarchy, date, version, and: classification)), embedding model selection (choosing: the embedding model that: best represents: the domain's specialized vocabulary — general-purpose embeddings (OpenAI ada, Cohere embed) work: reasonably for: general text but: underperform on: highly specialized technical vocabulary — we evaluate: multiple embedding models against: domain-specific retrieval benchmarks — measuring: whether the correct chunk is: retrieved for: known question-answer pairs from: the domain — and: fine-tune: embeddings when: off-the-shelf models do not: achieve: acceptable retrieval accuracy for: domain-specific terminology), retrieval strategy (defining: how the system finds: relevant documents for: each query — hybrid retrieval (combining: semantic search (embedding similarity) with: keyword search (BM25) — semantic search handles: paraphrased questions and: conceptual similarity — keyword search handles: exact technical terms, rule numbers, and: document identifiers — the combination: provides: better retrieval than: either approach alone), with: re-ranking (a second-pass model that: re-scores: retrieved documents for: relevance before: passing them to: the generation model — improving: precision at: the cost of: modest latency)), and generation architecture (configuring: the language model to: generate: accurate, grounded answers from: retrieved documents — system prompt engineering (instructing: the model to: answer only from: the provided documents, cite: sources for: every claim, acknowledge: when: the retrieved documents do not: contain: sufficient information to: answer the question, and: never: fabricate information), citation formatting (defining: how sources are: cited — document title, section, page number, and: direct quotation for: critical facts — enabling: users to: verify: every answer against: the source material), and: answer structure (defining: the output format appropriate for: each domain — for aerospace: concise technical answers with: specific numerical values and: document citations — for cannabis compliance: plain-language explanations with: rule section citations — for energy regulatory: comprehensive analysis with: citations to: multiple proceedings))). Phase 3 — Development and Tuning (4-8 weeks): building and optimizing the RAG system: document pipeline (building: the automated pipeline that: ingests documents, processes them (OCR, parsing, cleaning, chunking), generates: embeddings, and: stores: them in: the vector database — with: incremental update capability (new documents added: without: reprocessing the entire corpus) and: version management (when: a document is: updated: the old version is: archived and: the new version replaces: it in: the retrieval index)), retrieval optimization (iteratively: improving retrieval accuracy — testing: retrieval against: a benchmark set of: questions with: known correct source documents — tuning: chunk size, overlap, embedding model, retrieval parameters, and: re-ranking model to: maximize: the percentage of: queries where: the correct source is: retrieved in: the top results), generation tuning (optimizing: the generation model's behavior — prompt engineering to: minimize: hallucination (the model generating: information not present in: the retrieved documents), maximize: citation accuracy, and: produce: answers in: the appropriate domain style and: format — testing: against: domain expert evaluations of: answer quality, accuracy, and: completeness), and guardrails (implementing: safety mechanisms — hallucination detection (comparing: generated claims against: retrieved source text — flagging: or: suppressing: claims that: cannot be: traced to: source documents), confidence scoring (providing: a confidence indicator based on: retrieval similarity scores and: answer grounding — low-confidence answers are: flagged for: human review), and: access controls (ensuring: users only: receive: answers from: documents they are: authorized to: access — critical for: aerospace with: classification levels and: government with: FOUO restrictions))). Phase 4 — Validation and Deployment (2-3 weeks): ensuring accuracy for high-stakes domains: domain expert evaluation (having: aerospace engineers, cannabis compliance officers, energy regulatory analysts, and: government officials evaluate: RAG answers against: their professional knowledge — identifying: inaccuracies, missing information, and: citation errors), accuracy benchmarking (measuring: RAG performance on: held-out question-answer pairs: retrieval accuracy (% of questions where: the correct source is: retrieved), answer accuracy (% of answers rated: correct by: domain experts), citation accuracy (% of citations that: correctly reference: the source of: each claim), and: hallucination rate (% of answers containing: information not present in: source documents)), SB 24-205 compliance verification (for RAG systems that: inform: high-risk decisions: verifying: transparency (every answer includes: source citations), explainability (users can: trace: every claim to: source documents), and: human oversight (users can: access: source documents to: verify: AI answers)), and deployment with monitoring (deploying: with: ongoing monitoring of: retrieval accuracy, answer quality, and: user satisfaction — with: automated re-indexing when: new documents are: added and: periodic: accuracy reassessment as: the document corpus evolves)).
