RAG-Based Knowledge Base

RAG-Based Knowledge Base is a professional ai intelligence service delivered by Pakish.NET with end-to-end setup, quality checks, and implementation support.

What is RAG-Based Knowledge Base?

A RAG-based knowledge base ingests your documents, chunks and embeds them for semantic search, and answers questions with citations pointing to the exact source passages. Hybrid retrieval combines keyword and vector search so acronyms and SKU codes still match. Access controls mirror your folder permissions so confidential HR or finance docs never surface to unauthorized users. Re-indexing runs on a schedule or webhook when source files change.

When This Service Is Not the Right Fit

  • Knowledge that changes hourly without any stable source document.
  • Organizations unwilling to classify documents by sensitivity level.
  • Use cases requiring real-time data from transactional databases without a sync layer.
  • Tiny FAQ sets under twenty pages where keyword search already suffices.

Ideal Use Cases

  • Internal employee handbook and HR policy Q&A with role-based visibility.
  • Customer support grounded strictly in approved public help articles.
  • Field service teams querying equipment manuals and troubleshooting trees on mobile.
  • Legal or compliance teams searching contract clauses across archived PDFs.
  • Product managers asking natural-language questions over research notes and specs.

Problems This Service Solves

  • Staff waste time searching across Confluence, Drive, and email for the same policy answers.
  • New hires cannot find updated SOPs because filenames and folder structures are inconsistent.
  • Generic LLM chat gives plausible but wrong answers about internal procedures.
  • Subject matter experts interrupt their work to answer repeat Slack questions.
  • Compliance audits struggle to prove which document version was authoritative on a given date.

Discovery and Implementation Stages

  1. 1. Corpus audit & access model

    We classify documents by sensitivity, identify duplicates and outdated versions, and define which collections each user group retrieves from.

  2. 2. Ingestion & chunking pipeline

    Connectors pull text from PDFs, slides, and wikis. Tables and headings inform chunk boundaries to keep answers coherent.

  3. 3. Retrieval evaluation

    Held-out questions measure recall and citation accuracy. Hybrid weights tuned until acronym and paraphrase queries both succeed.

  4. 4. Interface deployment

    Slack bot, web widget, or internal portal goes live with logging. Users see cited snippets before expanded answers.

  5. 5. Re-index & governance handover

    Scheduled re-index verified after source updates. Admins trained on purge workflows when documents retire.

What's Included

Ingestion connectors for agreed source systems and file formats
Chunking strategy documentation with overlap and metadata rules
Vector index with hybrid keyword + semantic retrieval
Answer UI or API returning citations with page or section anchors
Access control mapping from source permissions to retrieval filters
Re-index job with change detection and failure alerting
Evaluation report against held-out question set from your team
Administrator guide for adding collections and purging retired docs

Security and Privacy Considerations

  • Embeddings inherit document ACLs enforced at query time
  • Query logs optionally anonymized or disabled for sensitive collections
  • Source credentials rotated through secrets manager
  • No cross-tenant index sharing in multi-team deployments
  • Right-to-erasure workflow removes chunks when source files delete

Acceptance Criteria

  • Evaluation set achieves agreed citation accuracy on approved questions
  • Unauthorized role cannot retrieve chunks from restricted collection in penetration test
  • Re-index completes within defined window after sample document update
  • Answers include at least one source link matching human-verified ground truth
  • Hybrid search retrieves acronym-specific doc when vector-only search misses

Integration Dependencies

  • Read access to source repositories with stable API or export paths
  • Embedding model API or self-hosted embedding endpoint decision finalized
  • Vector database hosting choice aligned with your infra (cloud or VPC)
  • Identity provider groups if retrieval must match SSO roles

Post-Launch Support Scope

  • Quarterly retrieval quality reviews with new question samples
  • Connector maintenance when source APIs change
  • Chunk strategy adjustments when new doc templates introduced
  • Optional managed re-index and deprecated doc purge service

RAG-Based Knowledge Base FAQs

Common questions about our AI Intelligence service.

Common formats include PDF, DOCX, PPTX, HTML, Markdown, and plain text from wikis. Scanned PDFs may need OCR preprocessing, which we scope separately if image-only pages dominate.
Vector search excels at paraphrased questions; keyword search catches exact codes, SKUs, and acronyms. Hybrid ranking merges both signals so neither failure mode dominates.
Citations link to source path and chunk metadata including ingest timestamp. If versioning is stored in filename or metadata, we surface that so users know whether they read the current policy.
Webhook-triggered re-index on publish events is ideal. Where webhooks are unavailable, nightly or weekly schedules balance freshness against compute cost.
RAG augments search with synthesized answers and citations. Many teams keep traditional search for browsing while RAG handles natural-language questions. Scope depends on user workflows.
Filters at query time using SSO groups, source-system ACL sync, or manually maintained collection tags. The strictest model mirrors live folder permissions from Drive or SharePoint.
