How knowledge-based agents work

Here's a step-by-step breakdown of how knowledge-based agents work:

Step 1: Perceive the environment
The first thing the agent does is gather information from its environment. This could be a query from a user, a sensor reading, or data coming from another system. Consider a customer support case: Someone asks, “How can I reset my account password?” The agent takes that information and prepares to find possible solutions.

Step 2: Interpret the input
This is where the magic of natural language processing (NLP) comes into play. The agent analyzes the input to figure out precisely what the user needs . It detects 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, accurate answers without having to go back and forth.

Step 3: Access the knowledge base
The agent then dives into your knowledge management system or knowledge base software to find hr directors email list the most relevant information. He searches through stored facts, rules, and other useful data to find exactly what is needed. In this case, you can find a step-by-step guide to resetting passwords. This is where a well-organized knowledge-based system makes all the difference.

Step 4: Reasoning and decision making
Now, the agent really shows its intelligence. Using its inference engine, it applies logical rules to the retrieved knowledge to provide a relevant and personalized response . If the user also mentions, “I tried resetting it and it still doesn’t work,” the agent can suggest that the user check the email for errors or if the account is blocked. It’s not just about giving answers, but about thinking about the problem to offer the best solution.

Step 5: Deliver the result
Finally, the agent delivers the answer in a clear and actionable way. This can be a simple text response, a step-by-step visual guide, or an automated action such as triggering a password reset email. With the right AI knowledge base software, these tasks are seamlessly handled, saving time for both the user and the team.

One of the first 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 was not widely adopted due to ethical and legal concerns at the time.
