3.6 Knowledge Base Q&A (Knowledge‑QA Integration)

Pop’s Knowledge Base Q&A allows the AI to go beyond being a “general model” — it can read your own documents, project materials, product manuals, team notes, research papers, and more, providing fact‑based and content‑grounded answers.

Knowledge‑based Q&A is ideal for:

  • Project documentation, system descriptions, technical specs
  • Internal company SOPs and business processes
  • Personal reading notes and research material
  • Domains requiring factual accuracy (legal, medical, finance)

Pop structures your materials so the AI becomes your personal knowledge assistant.


📚 What Types of Content Can Pop’s Knowledge Base Use?

You can build a KB from many types of resources, including:

  • PDF documents
  • Markdown / plain text
  • Word / Excel / PowerPoint
  • Web page content
  • Your handwritten notes
  • Auto‑synced online documents (coming soon)

Each knowledge base supports:

  • Document management
  • Chunk indexing
  • Embedding vector retrieval
  • BM25 / Hybrid retrieval
  • AI answers grounded in retrieved content

🔍 Deep Integration with the AI Assistant

Inside the AI chat interface, you can select one or more knowledge bases:

Option 1: Choose KB in the top‑right of the chat window

Click the “Knowledge Base” dropdown and select the KBs you want to enable.

Option 2: Bind a default KB to a persona

Each persona can have its own default KB, such as:

  • “Customer Service Assistant” → FAQ KB
  • “Financial Advisor” → Finance Policy KB
  • “Developer Assistant” → Project Docs KB

When bound, all answers from that persona automatically use its KB.


🎯 How Knowledge Base Q&A Works

Pop uses a Retrieval‑Augmented Generation (RAG) pipeline:

  1. You ask a question
  2. The system retrieves relevant document chunks (BM25 / Vector / Hybrid)
  3. The retrieved text is passed as “context” to the AI
  4. The AI generates a grounded answer
  5. The final answer includes source citations

Ensuring answers are:

  • More accurate
  • Verifiable
  • Traceable

📌 Retrieval Modes (BM25 / KNN / Hybrid)

Pop supports three retrieval strategies:

Mode Features Best For
BM25 (Keyword Search) Fast, keyword‑based Clean text with clear keywords
KNN (Vector Search) Semantic understanding Natural language, varied phrasing
Hybrid Combines both advantages Most scenarios (recommended)

Pop automatically uses the optimal method based on your KB configuration.


📎 Source Citations

Every generated answer includes references:

  • Document name
  • Relevant chunk preview
  • Click to jump to the exact location in the document

Example:

According to Section 3.2 of the Project Design Document

This ensures transparency and trustworthiness.


✏️ Tips for Improving Answer Accuracy

Follow these suggestions:

  • Use clean document formats (PDF / Markdown preferred)
  • Large documents are automatically chunked (Pop handles this)
  • Make your questions specific
    • ❌ “Introduce this system.”
    • ✅ “Based on Section 2.3 of the Architecture Document, explain the microservice design.”
  • Combine multiple KBs for richer answers

📦 Multi‑Knowledge‑Base Answers

Pop supports using multiple KBs simultaneously in a single conversation:

  • “Product Docs + Technical Specs” → architecture questions
  • “Manual KB + FAQ KB” → customer support
  • “Reading Notes + Research Papers” → academic summaries

Pop merges retrieval results to maximize accuracy.


⚙️ Managing and Updating Knowledge Bases

In the Knowledge Base Management interface, you can:

  • Create KBs
  • Add / delete documents
  • Re‑index content
  • Bind KB to personas
  • Configure retrieval modes
  • View indexing status

These settings directly affect AI accuracy and coverage.


🔒 Privacy & Security

All documents you upload are stored locally or on your private server.
Pop never uploads your content externally unless you explicitly connect to a remote model.

  • Document processing occurs locally
  • Vector database is stored locally
  • Knowledge data is never used for model training

Suitable for enterprise security scenarios.


📌 Summary

Knowledge Base Q&A transforms Pop from a “general chat assistant” into a powerful content‑aware intelligent system.

Use KBs to:

  • Enable fact‑grounded answers
  • Build enterprise internal assistants
  • Manage multi‑project documentation
  • Quickly summarize and search your documents
