Exploring AI Agents in RAG: Types and Uses

Previously published on Nuclia.com. Nuclia is now Progress Agentic RAG.

What is an AI Agent?

An AI agent refers to a software entity that performs automated tasks on behalf of humans or other systems. These agents are programmed to make decisions and take actions based on their environment and predefined goals. They can operate autonomously or semi-autonomously, and are commonly used to manage complex processes or datasets more efficiently than a human could. In the context of AI and machine learning (ML), agents often leverage algorithms to analyze data, learn from outcomes and improve their performance over time.

What Types of AI Agents Exist?

AI agents can broadly be categorized into several types—each with specific functions and purposes. For the scope of Retrieval-Augmented Generation (RAG), we primarily discuss two main types:

Task-Specific Agents:

These agents are designed to perform a single, specific task. They are employed at various stages of data handling:

• At ingestion: These agents might be used for auto-classification, summarizing documents, generating questions and answer pairs, etc.
• At retrieval: Examples include Query Refinement Agents, which enhance the search-retrieval process by improving the initial query to ensure the retrieved information is more relevant, and Reasoning Agents, which help determine which pieces of information best answer a user’s query or make recommendations based on multiple data points.

Multi-Step Agents:

These agents integrate more than one task-specific agent to perform a series of tasks. For example, an agent might first classify a document into specific categories and then summarize it based on its classification. Another example could be an agent detecting a specific set of named entities in a resource, and based on those entities, performing subsequent specialized tasks.

Evolving Landscape of AI Agents

The world of AI agents is constantly evolving, with concepts and technologies continually consolidating and advancing. In the RAG framework, the ability to create and refine these agents offers significant potential to enhance how we handle, retrieve and interpret large datasets, making information retrieval not only faster, but also more pertinent and contextually aware.

Benefits of AI Agents for Business

AI agents offer a plethora of benefits across various business functions by automating complex tasks, enhancing accuracy and streamlining operations. Here’s how AI agents can be particularly beneficial in a business context:

Enhanced Efficiency

AI agents excel at handling repetitive and data-intensive tasks with greater speed and precision than their human counterparts. For example, auto-classification agents swiftly organize vast amounts of unstructured data into meaningful categories, significantly reducing the time and effort required for data management. This allows employees to focus on more strategic activities that add greater value to the business.

Improved Decision Making

By integrating reasoning agents, businesses can enhance their decision-making processes. These agents analyze data to provide well-founded answers to complex queries, ensuring that decisions are based on accurate and up-to-date information. This is particularly valuable in dynamic industries, where timely and accurate information is critical for maintaining competitive advantage.

Customized Customer Experiences

Query refinement agents improve the search-retrieval process, which can be tailored to customer interactions in customer service platforms. By providing more relevant results based on the user’s initial query, businesses can offer a personalized experience that directly addresses the customer’s needs, thereby improving satisfaction and loyalty.

Scalability

Multi-step agents demonstrate how AI can be used to scale business operations efficiently. For example, an agent designed to detect specific named entities and then perform subsequent tasks based on these entities can automate complex workflows in customer support or content management, adapting as volumes increase without additional human resource investment.

Risk Reduction

Automating tasks with AI agents reduces the likelihood of human error and enhances compliance with regulations. For instance, summarization agents can help ensure that all critical information is highlighted and easily accessible for compliance reviews, reducing the risk of non-compliance penalties.
