Build Smarter Chatbots with a Custom RAG Pipeline

This article provides a step-by-step guide to building a custom Retrieval-Augmented Generation (RAG) pipeline for AI chatbots, emphasizing the use of embeddings to enhance retrieval accuracy from a custom knowledge base. By combining retrieval and generative components, the pipeline ensures domain-specific, contextually accurate responses tailored to organizational needs.


Build a Custom RAG Pipeline with Embeddings

Introduction

Retrieval-Augmented Generation (RAG) is a powerful framework that combines retrieval mechanisms with generative AI to provide contextually accurate responses. By integrating embeddings, you can enhance the RAG pipeline's ability to extract relevant information from a custom knowledge base, making it an excellent choice for building an AI chatbot tailored to your organization's specific needs.

This article walks you through the steps to build a custom RAG pipeline using embeddings, with a focus on an AI chatbot that interacts with a custom knowledge base. From understanding embeddings to implementing a scalable pipeline, this guide is your go-to resource for building an intelligent chatbot.

Why Use a RAG Pipeline for AI Chatbots?

AI chatbots often rely on pre-trained models which may not have access to domain-specific knowledge. A RAG pipeline addresses this limitation by combining two core components:

  • Retriever: Extracts relevant documents or pieces of information from a knowledge base.
  • Generator: Synthesizes a coherent, contextually accurate response based on the retrieved information.

By incorporating embeddings, the retriever becomes more effective at finding semantically relevant information, ensuring the chatbot provides highly accurate and context-aware responses.

Steps to Build a Custom RAG Pipeline

1. Prepare Your Knowledge Base

Start by curating a custom knowledge base that contains the information your chatbot should access. This could be:

  • Internal company documents
  • FAQs
  • Research papers
  • User manuals

Ensure that the documents are in a structured or semi-structured format (e.g., JSON, text files, or databases) for easier processing.

2. Create Embeddings for the Knowledge Base

Embeddings are vector representations of text that

Data Product Approach

Why Build Data Products

Companies should build data products because they transform raw data into actionable, reusable assets that directly drive business outcomes. Instead of treating data as a byproduct of operations, a data product approach emphasizes usability, governance, and value creation. Ultimately, they turn data from a cost center into a growth engine, unlocking compounding value across every function of the enterprise.
