Welcome to this live coding tutorial on how to build your own AI agent in Java. In this practical and hands-on session, we will briefly cover the theory of AI applications before diving into the actual coding. This tutorial is designed for both newcomers and experienced developers who might want to refresh their minds on the concepts surrounding AI-powered applications.
To kick things off, let's consider a real-world scenario involving AI. Recently, I had to navigate a complex medical report for my dog, Nova. The report was filled with dense jargon, so I turned to ChatGPT for help. I provided it with instructions to interpret the medical jargon in an easy-to-understand manner. The response was a concise summary that alleviated our concerns regarding Nova's health. This highlighted the potential of AI to assist us if used correctly.
However, despite their capabilities, large language models (LLMs) can struggle with specific context-related issues. This presents challenges when building AI applications since real-world problems often require context that the AI may not possess. To enhance the effectiveness of AI applications, developers must provide the necessary contextual information.
As a case study, we'll build a simulated customer support agent for an airline. The application will allow users to inquire about cancellation policies, booking details, modifications, and cancellations. Here’s the approach we'll take:
The user interface will have a chat feature integrated with a live view of bookings. Key functionalities will include fetching cancellation policies, booking details, and the ability to modify existing bookings.
For our project, we will create a Spring Boot application as the back end, integrating LangChain for J to handle AI functionalities. Here’s a step-by-step breakdown of the components we'll create:
The AI assistant will be initialized with guidelines to maintain a friendly demeanor and understand its role as a customer support agent. As we build the application, it is critical to ensure that the assistant can reference the chat history to authenticate user requests.
Next, we will go beyond just answering questions. The AI will be equipped to run specific functions such as:
In this section, we will create a "Booking Tools" class, which contains methods to interact with our flight service.
In this demo, we've built a working AI agent capable of engaging users in conversation while providing access to their booking details. This implementation applies core AI concepts that enhance user experience without diving deep into the underlying mathematics or infrastructure.
The full project, including various versions using different libraries for further exploration, is available on my GitHub. Check out the repository for details!
