Large Language Models have significantly improved natural language understanding and content generation. However, traditional LLMs operate using pre-trained knowledge and cannot reliably answer questions about proprietary organisational documents unless that information is incorporated into the model's context.

Retrieval-Augmented Generation (RAG) addresses this challenge by combining semantic document retrieval with LLM reasoning. Instead of asking an AI to "guess" an answer, a RAG system retrieves the most relevant document fragments and provides them as context for response generation.

This paper presents a comprehensive tutorial for deploying RAGFlow with Ollama on Ubuntu Linux. Topics include system architecture, deployment planning, model selection, security considerations, hardware sizing and practical business use cases. The tutorial also explores how SMEs and engineering organisations can use local AI infrastructure to improve productivity, knowledge management and decision support while maintaining control over sensitive information.

This tutorial is intended for educational and professional purposes. Readers are encouraged to evaluate security, licensing, hardware requirements and organisational policies before deploying AI systems in production environments.

Executive Summary

Artificial Intelligence is rapidly transforming how organisations manage and retrieve information. While cloud-based AI services offer powerful capabilities, many businesses hesitate to adopt them because of concerns over data privacy, intellectual property protection, regulatory compliance and recurring subscription costs.

Retrieval-Augmented Generation (RAG) provides a practical alternative. Rather than relying solely on the knowledge contained within a Large Language Model (LLM), a RAG system retrieves relevant information from an organisation's own documents before generating a response. This approach improves factual accuracy while enabling businesses to keep sensitive information under their own control.

This tutorial demonstrates how to build a secure, private AI knowledge platform using RAGFlow and Ollama on Ubuntu Linux. The solution enables organisations to create conversational AI assistants that answer questions using internal documentation, technical manuals, research papers, policies, operating procedures and engineering knowledge bases.

Unlike many introductory guides, this publication focuses on enterprise deployment, real-world implementation and long-term maintainability. Readers will learn not only how to install the software, but also how to design an architecture suitable for engineering firms, SMEs, educational institutions, research laboratories and industrial organisations.

Throughout this tutorial, two complementary organisations illustrate how these technologies can support digital transformation:

• KeenComputer.com – delivering practical IT infrastructure, cloud, DevOps, digital transformation and managed AI solutions for SMEs.
• IAS-Research.com – providing multidisciplinary engineering, AI research, embedded systems expertise, Industrial IoT consulting and technology innovation services.

Together, these capabilities bridge the gap between research and production deployment.

1. Introduction

Modern organisations create enormous amounts of information every day. Engineering drawings, technical manuals, maintenance procedures, software documentation, meeting notes, policies, research papers and customer communications all contribute to a growing body of institutional knowledge.

Unfortunately, much of this information remains difficult to access. Traditional keyword searches often return hundreds of documents, requiring employees to spend valuable time locating the information they actually need.

Large Language Models (LLMs) offer a more intuitive way to interact with information by allowing users to ask questions in natural language. However, public AI services are often unsuitable for confidential business data due to privacy concerns, compliance requirements or contractual obligations.

A private RAG platform addresses these challenges by enabling organisations to deploy AI on infrastructure they control. Users can ask questions such as:

• "Summarise our network disaster recovery procedure."
• "Compare Revision A and Revision B of the design specification."
• "List the safety requirements for this equipment."
• "Which maintenance tasks are required every six months?"

Instead of searching manually through multiple documents, the AI retrieves relevant sections from the organisation's knowledge base and uses them to generate a grounded response.

2. Why Local AI Matters

Cloud AI services are convenient, but they are not always appropriate for every workload. Organisations in sectors such as engineering, manufacturing, healthcare, finance and government often require greater control over their information.

A local AI deployment offers several advantages:

• Data remains within the organisation's infrastructure.
• Reduced exposure of confidential intellectual property.
• Greater control over software updates and model versions.
• Predictable operating costs without per-query pricing.
• Easier integration with existing internal systems.
• Support for offline or restricted-network environments.

These characteristics make local AI particularly attractive for organisations with sensitive technical documentation or regulatory obligations.

3. Understanding Large Language Models

Large Language Models are neural networks trained on extensive collections of text. They learn statistical relationships between words and concepts, enabling them to generate coherent responses, summarise information, translate languages and assist with coding.

Popular open-weight models include:

Model	Typical Strength
Llama 3.x	General-purpose conversation and summarisation
Qwen 2.5	Technical reasoning and coding
Gemma	Lightweight local deployments
Mistral	Fast inference with strong performance
DeepSeek	Advanced reasoning tasks

While these models are powerful, they do not automatically know the contents of an organisation's private documents. This limitation is where Retrieval-Augmented Generation becomes essential.

4. What is Retrieval-Augmented Generation (RAG)?

Retrieval-Augmented Generation combines two complementary capabilities:

1. Information Retrieval – locating relevant passages from a document collection.
2. Language Generation – producing a natural-language response using those retrieved passages.

Instead of relying solely on the model's internal knowledge, the system first searches the knowledge base and then uses the retrieved content as context.

User Question │ ▼ Semantic Search Engine │ ▼ Relevant Document Chunks │ ▼ Large Language Model │ ▼ Grounded AI Response

This approach offers several benefits:

• Improved factual accuracy.
• Reduced hallucinations.
• Traceability to source documents.
• Easier updating of knowledge without retraining the model.
• Better support for proprietary information.

5. Understanding Ollama

Ollama is an open-source platform for running Large Language Models locally. It simplifies model management by providing a consistent command-line interface and a REST API that can be consumed by applications such as RAGFlow.

Key capabilities include:

• Local model execution.
• Simple installation on Linux, macOS and Windows.
• Support for CPU and GPU inference.
• Easy downloading of open-weight models.
• Model version management.
• HTTP API for application integration.

Because Ollama exposes a standard API, it can serve multiple applications simultaneously, making it a practical choice for enterprise deployments.

6. Understanding RAGFlow

RAGFlow is a Retrieval-Augmented Generation platform that manages the entire document processing pipeline.

Its responsibilities include:

• Document ingestion.
• OCR (where applicable).
• Text extraction.
• Intelligent chunking.
• Embedding generation.
• Vector indexing.
• Semantic search.
• Chat interfaces.
• Knowledge-base management.

Rather than replacing an LLM, RAGFlow orchestrates the retrieval process, ensuring that the language model receives relevant contextual information before generating a response.

7. System Architecture

A typical deployment separates responsibilities into distinct components.

Users │ ▼ Web Browser │ ▼ RAGFlow UI │ ┌───────────────┼───────────────┐ │ │ │ ▼ ▼ ▼ Document Parser Vector Database Chat Engine │ │ │ └───────────────┼───────────────┘ ▼ Ollama Server │ ┌───────────┴───────────┐ │ │ Chat Model Embedding Model

This modular architecture allows each component to be upgraded or scaled independently.

8. Business Benefits

A private AI knowledge platform can provide measurable improvements across multiple business functions:

• Faster access to organisational knowledge.
• Reduced time spent searching documentation.
• Improved onboarding of new employees.
• Better customer support through AI-assisted responses.
• Preservation of institutional knowledge.
• Enhanced collaboration across departments.

By grounding responses in approved documentation, organisations can improve consistency while reducing the risk of unsupported or fabricated answers.

9. Digital Transformation for SMEs

Small and medium-sized enterprises often have limited IT resources but still need efficient access to organisational knowledge. A locally deployed RAG platform enables SMEs to:

• Create searchable knowledge repositories.
• Support customer service teams.
• Improve proposal development.
• Enhance technical support.
• Assist with employee training.
• Reduce dependence on external cloud AI services.

Because the platform can run on commodity hardware or a private virtual server, it provides a cost-effective path towards AI adoption.

Building a Private AI Knowledge Platform with RAGFlow and Ollama

Part 3 – Knowledge Bases, Document Processing, Embeddings, Retrieval Optimisation and AI Workflows

A Practical Enterprise Tutorial for SMEs, Engineers, Researchers and IT Professionals

34. Introduction

In Part 2, we successfully deployed a private AI platform using Ubuntu, Docker, Ollama and RAGFlow. The infrastructure is now ready to process organisational knowledge.

This chapter focuses on what transforms a language model into a useful enterprise assistant: building high-quality knowledge bases. Readers will learn how documents are processed, indexed and retrieved, how embedding models influence search quality, and how to optimise Retrieval-Augmented Generation (RAG) for technical and business documents.

By the end of this chapter, you will understand how to:

• Design effective knowledge bases.
• Import and prepare documents.
• Improve retrieval quality.
• Configure chunking and embeddings.
• Use reranking to increase answer accuracy.
• Build AI workflows for engineering, research and business operations.

35. Understanding Enterprise Knowledge Bases

A knowledge base is a structured repository of information that an AI system can search before generating answers. Unlike traditional file shares, documents are indexed semantically, allowing users to ask questions in natural language.

Typical enterprise knowledge bases include:

• Policies and procedures
• Engineering manuals
• Standard operating procedures (SOPs)
• Technical specifications
• Research papers
• Software documentation
• Product manuals
• Customer support guides
• Compliance documents
• Training materials

Instead of searching by exact keywords, semantic search identifies documents based on meaning and context.

36. Designing an Effective Knowledge Base

Successful deployments begin with thoughtful organisation. Rather than placing every document into one large repository, separate knowledge bases by function or audience.

Examples include:

Knowledge Base	Contents
Engineering	Drawings, specifications, standards, manuals
IT Operations	Network diagrams, SOPs, backup procedures
Human Resources	Employee handbook, policies, training
Sales & Marketing	Product information, proposals, presentations
Customer Support	FAQs, troubleshooting guides, installation manuals
Research	White papers, journal articles, technical reports

This separation improves retrieval accuracy and simplifies access control.

37. Supported Document Types

RAGFlow supports a broad range of business and technical documents, including:

• PDF
• Microsoft Word (DOCX)
• PowerPoint (PPTX)
• Excel spreadsheets
• CSV files
• Markdown
• HTML
• Plain text
• JSON
• Source code repositories

For scanned documents, Optical Character Recognition (OCR) extracts searchable text before indexing.

38. Document Processing Pipeline

Every uploaded document passes through several processing stages before becoming searchable.

Upload Document │ ▼ Document Parsing │ ▼ Text Extraction │ ▼ Cleaning & Normalisation │ ▼ Chunking │ ▼ Embedding Generation │ ▼ Vector Database │ ▼ Semantic Search

Each stage contributes to the overall quality of AI-generated answers.

39. Document Parsing

Parsing converts raw files into structured text.

Examples include:

• Extracting paragraphs from PDF files.
• Reading headings from Word documents.
• Preserving tables where possible.
• Identifying images and captions.
• Maintaining document hierarchy.

High-quality parsing improves retrieval performance and reduces indexing errors.

40. Text Cleaning

Before embeddings are generated, documents should be cleaned by:

• Removing duplicate headers and footers.
• Eliminating page numbers.
• Correcting OCR errors.
• Standardising whitespace.
• Removing unnecessary formatting.

Clean text produces more meaningful embeddings and reduces noise during retrieval.

41. Chunking Strategies

Large Language Models cannot process entire document libraries simultaneously. Instead, documents are divided into manageable sections known as chunks.

Common chunking methods include:

Fixed-Length Chunking

Splits text into blocks of a specified number of tokens.

Advantages:

• Simple
• Fast
• Predictable

Limitations:

• May split important ideas.

Paragraph-Based Chunking

Preserves paragraph boundaries, making responses more coherent.

Suitable for:

• Technical documentation
• Policies
• Research papers

Heading-Based Chunking

Uses document headings to define chunk boundaries.

Ideal for:

• User manuals
• Standards
• Books
• White papers

Semantic Chunking

Groups text according to meaning rather than length.

Advantages:

• Better retrieval accuracy
• Improved context preservation

Although more computationally intensive, semantic chunking often provides the best results for engineering and research documentation.

42. Choosing Chunk Size

Recommended starting points include:

Document Type	Chunk Size
Research papers	700–1,000 tokens
Engineering manuals	800–1,200 tokens
Policies	500–800 tokens
Technical specifications	600–900 tokens
Software documentation	600–1,000 tokens

Experimentation is recommended to determine the optimal settings for each knowledge base.

43. Embeddings Explained

Embeddings transform text into numerical vectors that capture semantic meaning.

Unlike keyword search, embeddings allow the system to recognise that:

"UPS battery replacement"

and

"changing the backup power batteries"

describe similar concepts.

This capability enables semantic retrieval rather than literal string matching.

44. Why BGE-M3?

BGE-M3 is widely used because it offers:

• High retrieval accuracy
• Multilingual support
• Strong technical language understanding
• Efficient inference
• Excellent compatibility with RAGFlow

For organisations working with engineering, scientific and business documentation, BGE-M3 provides an effective balance between quality and performance.

45. Vector Databases

After embeddings are generated, they are stored in a vector database.

Unlike relational databases, vector databases search by similarity rather than exact values.

Typical workflow:

User Question ↓ Embedding ↓ Vector Search ↓ Most Similar Chunks ↓ LLM Response

This process enables users to locate relevant information even when they use different wording from the original document.

46. Reranking Results

Initial retrieval may return several relevant document chunks. A reranking model evaluates these candidates and reorders them according to relevance.

Benefits include:

• More accurate responses.
• Better handling of ambiguous questions.
• Reduced irrelevant context.
• Improved performance with long documents.

A commonly recommended reranking model is BGE-Reranker-v2.

47. Prompt Engineering for Enterprise AI

Prompt engineering guides the language model to produce consistent, grounded responses.

Example system prompt:

You are an engineering assistant. Answer only using the retrieved documentation. If the answer is not found in the provided documents, clearly state that the information is unavailable rather than making assumptions. Where appropriate, reference document titles and section headings.

Such prompts help minimise hallucinations and encourage transparency.

48. Improving Retrieval Quality

Several techniques can improve answer quality:

• Use well-structured source documents.
• Remove duplicate content.
• Separate unrelated topics into different knowledge bases.
• Keep documents current.
• Select appropriate chunk sizes.
• Enable reranking.
• Use high-quality embedding models.
• Review retrieval logs and user feedback.

Continuous refinement typically leads to measurable improvements over time.

49. Knowledge Base Maintenance

Knowledge bases require ongoing maintenance to remain effective.

Recommended practices include:

• Archive obsolete documents.
• Re-index updated files.
• Apply consistent naming conventions.
• Track document versions.
• Remove duplicate uploads.
• Schedule periodic quality reviews.

A well-maintained repository improves both retrieval accuracy and user confidence.

50. Integrating with Open WebUI

Many organisations use Open WebUI to provide a user-friendly interface for local AI models.

Typical architecture:

Users │ ▼ Open WebUI │ ▼ RAGFlow │ ▼ Ollama │ ▼ LLM

Open WebUI complements RAGFlow by offering an intuitive chat experience while RAGFlow manages document retrieval.

51. Engineering Use Case

An electrical engineering consultancy maintains:

• IEC standards
• Equipment manuals
• Test procedures
• Commissioning reports
• Safety documentation

Engineers ask:

• "Summarise the commissioning checklist."
• "Which insulation resistance tests are required?"
• "Compare Revision 2 and Revision 4."

The system retrieves relevant passages and produces responses grounded in internal documentation, reducing manual searching and improving consistency.

52. SME Use Case

A growing manufacturing SME uploads:

• Employee handbooks
• Quality manuals
• ISO procedures
• Customer support documentation
• Supplier agreements

Staff members can quickly locate information such as:

• Holiday policies.
• Product installation procedures.
• Warranty conditions.
• Supplier requirements.

This reduces repetitive enquiries and accelerates onboarding for new employees.

53. Academic Research Use Case

A university research group indexes:

• Journal articles
• Theses
• Conference papers
• Laboratory notebooks
• Grant documentation

Researchers use conversational search to:

• Identify related work.
• Compare methodologies.
• Summarise literature.
• Locate experimental results.

The platform becomes a collaborative research assistant while preserving institutional knowledge.

Building a Private AI Knowledge Platform with RAGFlow and Ollama

Part 4 – Enterprise Deployment, Security, Monitoring, High Availability and Production Operations

A Practical Enterprise Tutorial for SMEs, Engineers, Researchers and IT Professionals

58. Introduction

In Parts 1–3, we explored the foundations of Retrieval-Augmented Generation (RAG), deployed RAGFlow and Ollama on Ubuntu, and built high-quality knowledge bases. This chapter focuses on transforming a functional installation into a secure, resilient and maintainable production platform.

Enterprise AI systems must address much more than model performance. Organisations need secure authentication, encrypted communications, backup and disaster recovery, monitoring, logging, capacity planning and operational procedures. These elements ensure that AI services remain available, secure and compliant with organisational policies.

By the end of this chapter, readers will understand how to design and operate an enterprise-ready deployment suitable for SMEs, engineering consultancies, research organisations and industrial enterprises.

59. Production Architecture
