Mastering Conversational AI: How to Construct a Knowledge-Infused Q&A ChatBot

In this article, we will explore how embedding can be used to build a knowledge base for your company. Imagine having an AI-powered repository of best practices and domain-specific knowledge at your fingertips. This knowledge base can empower your organization's day-to-day decision-making processes. While fine-tuning large language models can achieve certain outcomes, embedding provides a unique approach to harnessing your company's specific knowledge.

Understanding the Difference

Fine-tuning a large language model is ideal when you want to mold the behavior of the model for specific tasks, like making it talk like a particular person. However, it may not be the best option for retrieving specific data or knowledge. This is where knowledge base embedding comes into play. It excels at giving a large language model specific domain knowledge, such as your company's standard operating procedures or proprietary data.

What Is Embedding?

Embedding is a technique used to represent data in vector form, showcasing the relative distances between data points. Think of it as a way to measure how similar or dissimilar data points are across multiple dimensions. While it may seem like data points are mapped in just two dimensions, in reality, they can be mapped in hundreds or even thousands of dimensions. Embedding models, such as OpenAI's embeddings, are pre-trained to understand the relationships between different data points, making them powerful tools for various types of data, including text, images, audio, and videos.

Vector Databases

Vector databases, like Pinecone and Chroma, are designed for storing and efficiently retrieving vector data. They play a crucial role in making similarity searches possible. When a user poses a question, the embedding model vectorizes it, enabling vector databases to identify relevant information within your company's documents based on the user's inquiry.

Core Business Use Cases

Knowledge base embedding can be a game-changer for business automation and workflow. Traditionally, company knowledge often resides in the minds of a few individuals. Articulating best practices can be challenging, and when these key employees leave, their knowledge leaves with them. Creating lengthy documents is a common but ineffective solution, as they quickly become outdated and lack quality control.

With knowledge base embedding, you can transform emails and customer interactions into embeddings. When a customer support agent receives a query or complaint, the system can perform a similarity search within the knowledge base to find past occurrences and the best responses. This approach bridges the gap between top-performing employees and junior staff, enabling you to create a knowledge base and have the large language model learn and replicate the behavior.

In the following example (with source code at the bottom). I will present a use case based on existing knowledge, how we can embed them with AI, and then ask some domain specific questions.

Steps to Build Your Knowledge Base

Step 1: Prep Knowledge Data

Begin by preparing your knowledge data. This could involve extracting relevant data from emails, documents, or other sources. This data will serve as the foundation for your knowledge base.

Step 2: Create Embeddings

Use an embedding model, such as OpenAI's text embedding model, to convert your data into vector representations. This step will enable you to measure the similarity between different data points effectively.

Develop a function for similarity search. When a user poses a question, use the vectorized query to search for the most relevant documents or data points within your knowledge base.

Step 4: Retrieval Augmented Generation (RAG)

Set up a large language model, like GPT-3.5, to generate responses based on the retrieved knowledge. Feed the search results into the model, enabling it to generate responses that mimic the style and content of your company's best practices.

Step 5: Deploy

You can deploy your knowledge base and AI components as a web application using platforms like Streamlit or no-code alternatives such as Relevance AI. This makes it accessible to your team members, allowing them to generate responses based on the knowledge base.

Sharing Your Knowledge Base

Once your knowledge base is ready, you can share it with your team members. Streamlit is a convenient tool for creating a user-friendly interface to interact with your knowledge base. You can also deploy your application online or embed it within your company's website.

No-code platforms like Relevance AI offer an easier way to set up knowledge embedding workflows and can be integrated into your existing tools and processes. These platforms often provide APIs for seamless integration into various workflow builders.

By leveraging knowledge base embedding, your organization can automate responses, streamline workflows, and ensure that valuable institutional knowledge is preserved and shared effectively.

I hope you find this exploration of knowledge base embedding helpful for your business's automation and workflow needs. Feel free to reach out if you have any questions or need further clarification.
