In this article, we’ll discuss the mechanics of knowledge-based agents in AI, how they’re transforming workplaces, and why they’re poised to become an essential part of every forward-thinking team.
How to Use Knowledge-Based Agents in AI
⏰ 60-Second Summary
- Knowledge-based agents are artificial intelligence systems that access, analyze, and deliver relevant information from a knowledge repository
- They are built on two main components: a knowledge base for storing data and an inference system for reasoning
- Knowledge-based agents gather inputs, interpret them, retrieve relevant knowledge, and provide actionable outputs
- Their applications include healthcare for patient support, customer service for instant help, and finance for compliance management
What Is a Knowledge-Based Agent?
A knowledge-based agent is an AI system that uses advanced AI techniques to access, interpret, and deliver information from a structured knowledge repository. Beyond storing data, these agents analyze the knowledge stored in databases to solve problems or provide actionable insights.
By representing knowledge in a machine-readable format via Knowledge Representation Language, they enable systems to interpret, reason, and make decisions.
They include methods like propositional logic, first-order logic, semantic networks, frames, and ontologies, each offering different ways to represent relationships and entities. KRLs are crucial for AI and information systems, allowing machines to store knowledge, derive conclusions, and communicate across platforms.
Unlike other AI agents (think chatbots or virtual assistants), knowledge-based agents can handle complex queries. It also facilitates significant improvements in time management and efficiency. Look at these stats from Mckinsey Global Institute:
📌 Example: Rufus, Amazon’s AI shopping assistant, functions as an AI knowledge management agent by leveraging a vast knowledge base encompassing product catalogs, customer reviews, Q&A, and web information.
Using natural language processing, Rufus understands customer queries and employs Retrieval Augmented Generation (RAG) to find relevant information and generate comprehensive responses. This process involves retrieving pertinent data from its knowledge base and augmenting it with the context of the user’s query.
Continuous learning through user feedback and reinforcement learning allows Rufus to refine its responses and improve its ability to provide helpful answers. In essence, Rufus centralizes, organizes, disseminates, and personalizes shopping-related knowledge, empowering customers to make informed purchase decisions.
Components of Knowledge-Based Agents
At the heart of every knowledge-based agent in artificial intelligence lie two key components: the knowledge base and the inference engine. These components work together to deliver intelligent, context-aware insights.
The knowledge base
Think of the knowledge base as the agent’s brain. It’s where all the essential facts, rules, and helpful tidbits are stored, ready to be used whenever needed. The knowledge base gives the agent its smarts—like an encyclopedia that doesn’t just sit on a shelf but actively helps make decisions. Unlike traditional databases, the knowledge base grows and evolves. New information gets added, and outdated details are replaced to provide relevant answers.
🧠 Did you know? The knowledge base can store both structured data (like spreadsheets) and unstructured data (like emails or chat logs), making it versatile for any type of query.
The inference engine
The inference engine is like the problem-solving partner of the knowledge base. It not only pulls up information but also applies logical reasoning to analyze data, draw conclusions, and make informed decisions based on the agent’s knowledge.
The inference engine gives a knowledge-based agent its ability to ‘reason’ and provide smart, context-aware answers.
It uses the following artificial intelligence techniques to provide insights and solutions:
| Technique | Meaning | Example |
| Deduction | Uses general rules or facts and applies them to derive conclusions | Rule: All employees with 10+ years of experience qualify for a senior management role Fact: Alex has 12 years of experience Conclusion: Alex qualifies for a senior management role |
| Induction | Draws generalized conclusions from specific examples or patterns. These conclusions are probable but not guaranteed. It helps with trend analysis | Observation: Team productivity increased by 15% during the last three months when flexible working hours were implemented Inductive conclusion: Flexible working hours likely improve productivity |
| Abduction | Starts with an observation and works backward to find the most likely explanation. It is commonly used for diagnosing or troubleshooting | Observation: The system’s response time is unusually slow Possible explanations (from the knowledge base): High server load or network issues Abductive conclusion: High server load is the most likely cause based on previous incidents |
Types of Knowledge-Based Agents
Knowledge-based AI agents come in various forms, each designed to tackle specific needs or environments. Let’s break down the main types of knowledge-based agents and how they excel in different scenarios:
Simple reflex agents
Simple reflex agents are like the ‘if-this-then-that’ experts of AI. They follow a set of predefined rules and react instantly to specific inputs without worrying about previous events. Think of them as reliable and straightforward companions—perfect for predictable, repetitive tasks.
📌 Example: A medical diagnosis system suggests a disease based on symptoms entered by a doctor, using the rule: “If fever, rash, and joint pain are present, then suggest dengue fever.”
But here’s the catch: Simple reflex agents are not exactly flexible. They rely solely on predefined rules; if things get too complex or start changing, these agents can’t adapt. Based on the above example, if the patient has any symptoms other than fever or rash, the AI agent might not be able to tell the condition.
Model-based agents
Model-based agents take AI tools for decision-making to the next logical level by building a mental map of their environment. This internal model helps them figure out what’s happening, even when they don’t have all the details.
📌 Example: A smart home system maintains an internal representation of the home environment, including factors like temperature, humidity, and occupancy. When it detects that the temperature exceeds the user’s preferred setting, it can adjust the thermostat.
Goal-based agents
These agents focus on achieving specific outcomes by evaluating actions against desired goals. They weigh different options and decide on the best path to success. Imagine an AI knowledge base helping a project team meet deadlines—it responds to questions according to its the background knowledge and proactively suggests steps to keep the project on track.
📌 Example: A GPS navigation system calculates the best route to a destination by considering the goal (reaching the location) and factors like traffic and distance, updating the route dynamically to achieve the goal efficiently.
Utility-based agents
Utility-based agents are the multitaskers of AI in the workplace. When there’s a lot going on and multiple goals to juggle, these agents step in to figure out the best course of action. They don’t just go for what’s possible but focus on what adds the most value overall.
📌 Example: In a resource allocation situation, a utility-based intelligent agent can evaluate options and prioritize decisions that save both time and money. It’s like having an AI teammate that always finds the smartest way to get the most out of your resources.
How Knowledge-Based Agents Work
Here’s a step-by-step breakdown of how knowledge-based agents function:
Step 1: Perceiving the environment
The first thing the agent does is gather input from its environment. This could be a user query, a sensor reading, or data coming from another system. Consider a customer support scenario: Someone asks, “How do I reset my account password?” The agent takes that input and gets ready to find possible solutions.
Step 2: Interpreting the input
This is where the magic of natural language processing (NLP) kicks in. The agent analyzes the input to figure out precisely what the user needs. It picks up on key phrases like ’reset’ and ‘account password’ to recognize the query as a troubleshooting request. With AI to automate tasks like these, users get fast and accurate responses without any extra back-and-forth.
Step 3: Accessing the knowledge base
Next, the agent dives into its knowledge management system or knowledge base software to find the most relevant information. It looks through stored facts, rules, and other helpful data to pinpoint exactly what’s needed. In this case, it might pull a step-by-step guide on resetting passwords. This is where having a well-organized knowledge-based system makes all the difference.
Step 4: Reasoning and decision-making
Now, the agent truly shows its intelligence. Using its inference engine, it applies logical rules to the retrieved knowledge to provide a relevant and customized response. If the user also mentions, “I’ve tried resetting it, and it’s still not working,” the agent might suggest checking for email errors or a locked account. It’s not just giving answers—it’s thinking through the problem to offer the best solution.
Step 5: Delivering the output
Finally, the agent delivers the response in a clear, actionable way. This could be a simple text reply, a visual step-by-step guide, or an automated action like triggering a password reset email. With the right AI-powered knowledge base software in place, these tasks are handled seamlessly, saving time for both the user and the team.
🧠 Did you know? One of the earliest applications of knowledge-based agents was in healthcare. MYCIN, developed in the 1970s at Stanford, was designed to diagnose bacterial infections and recommend treatments. Despite its accuracy, it wasn’t widely adopted due to ethical and legal concerns at the time.
