Building a conversational search chatbot for Martin County Library System

We recently had the opportunity to work with the Martin County Library System in Florida to develop a cutting-edge conversational search bot.

The goal of this project was to create an AI-powered chatbot that could understand and respond to user queries about the library system, providing constituents with quick and easy access to the information they need.

One of the key considerations in building this chatbot was to ensure that it remained focused on providing relevant, library-specific information. We wanted the chatbot to be able to handle common questions like "When does the library open?" or "How do I get a library card?" while avoiding off-topic inquiries that could lead to irrelevant or inaccurate responses.

Benefits of an AI-powered chatbot compared to traditional search functionality

The potential benefits of an AI-powered chatbot for enhancing the user experience and improving information accessibility are significant.

• The chatbot can understand user queries expressed in everyday language and provide accurate, targeted responses.
• The conversational interface is more intuitive and user-friendly than traditional search, which often requires users to navigate through complex menus or sift through long lists of search results.
• It can help reduce the burden on library staff by automatically handling a large volume of common inquiries, freeing up staff time and resources to focus on more complex tasks and provide higher-level support to library patrons.

Handling challenges like hallucinations and safeguarding against inappropriate use

One of the primary concerns is dealing with hallucinations—instances where the chatbot generates inaccurate, irrelevant, or nonsensical responses. To mitigate this issue, we employed a range of techniques:

1. Prompt engineering
2. Integrating with Solr search for more context
3. Providing conditional additional instructions
4. Iterative testing and refinement

Throughout the development process, we worked closely with the Martin County Library System to understand their specific needs and requirements, iterating on the chatbot's design and functionality to create a solution that met their goals and exceeded their expectations.

The end result is a powerful, AI-driven conversational search bot that is set to transform the way library patrons access information and interact with the library's digital resources.

In the following sections, we'll discuss the overview of the technical architecture and development process behind this chatbot solution, as well as explore the potential future developments and applications of AI and LLMs in the Drupal ecosystem and beyond.

Overview of the technical architecture and development process

To make the chatbot a reality, we architected custom Drupal modules specifically designed to support its AI functionality:

• Prometheus Core
• Prometheus Chatbot

These modules handled key aspects like data integration, ensuring the chatbot had access to the most up-to-date content from the Drupal site.

They also tackled prompt engineering, which involves crafting the right instructions and context for the LLM to generate accurate and relevant responses.

Handling extended conversations and optimizing performance were also crucial considerations in the development process.

Drupal's role in integrating AI and LLM technologies for a chatbot solution

Drupal serves as the foundation and central hub for the chatbot. It's where all the content lives and powers the search functionality.

We knew we needed to leverage Drupal's robust content management capabilities and integrate them seamlessly with the AI and LLM components.

Ensuring the integration of AI technologies maintains performance, accessibility, and user experience

One of the biggest challenges we faced was figuring out how to ensure that the integration of AI technologies within Drupal's architectural framework maintained high performance, accessibility, and user experience standards.

We didn't want the chatbot to slow down the site or create any barriers for users.

To tackle this, we used two main optimization techniques:

• Solr, to quickly retrieve relevant content from the Drupal site and feed it into the LLM.
• Caching mechanisms, to store frequently asked questions and their answers, reducing the need for redundant processing.

Prompt engineering and refining the chatbot's behavior

Another key aspect of the development process was prompt engineering. This involves carefully designing the prompts and instructions that are fed into the LLM, essentially teaching it how to understand and respond to user queries in the context of the library system.

We had to strike a balance between providing enough context for the LLM to generate accurate responses, while also keeping the prompts concise and efficient to maintain fast response times.

In the end, we were able to successfully architect a chatbot solution that leveraged the power of Drupal, Solr, and advanced AI and LLM technologies to create a seamless, intuitive, and highly effective conversational search experience for library patrons.
