Knowledge Engineer


A Knowledge Engineer is a professional who works in the field of artificial intelligence (AI) and designs, develops, and maintains systems that simulate the decision-making ability of a human expert. They apply their understanding of a particular subject to create computer programs that can solve complex problems. They are also responsible for encoding domain knowledge into data structures called knowledge bases.


The phonetic pronunciation of the phrase “Knowledge Engineer” is: ˈnɑːlɪdʒ ˌɛndʒəˈnɪər.

Key Takeaways

  1. Knowledge Engineers are professionals who create the rules and logic for artificial intelligence systems. They work closely with scientists and technologists to transform complex algorithms into workable AI models. This role requires deep knowledge in technology, analytics, and programming.
  2. Knowledge Engineers play an important role in building intelligent systems that can learn, adapt and improve over time. They work to understand and model knowledge from various sources including human experts, books, and databases for AI systems to use and interpret correctly.
  3. Being a Knowledge Engineer requires solid foundation in fields such as data science, computer science and cognition. They must possess skills in AI technologies, programming languages, machine learning, cognitive science, and have a deep understanding of structuring and organising information.


The term “Knowledge Engineer” is critically important in the field of technology as it refers to an individual or role responsible for implementing artificial intelligence systems. A Knowledge Engineer compiles and organizes information, creating databases in a comprehensive manner that computerized systems can understand and interact with. Their work forms the foundation for AI systems to generate accurate outcomes and facilitates machine learning by creating structured data frameworks. As AI’s prevalence and complexity grow across various industries, the role of a Knowledge Engineer increases in significance, making it an integral part of the development and advancement of AI technology.


A Knowledge Engineer primarily focuses on designing knowledge-based systems that simulate human intelligence for various purposes, such as problem-solving, learning and adaptation, understanding natural language, perception and more. This individual holds a crucial role in Artificial Intelligence (AI) as they work on machine learning algorithms and data mining techniques, among others, to create solutions that allow systems not just to store and retrieve information, but to “understand” and manipulate the knowledge they have gathered.The Knowledge Engineer serves a two-fold purpose. First, the engineer seeks to provide a basis for AI systems to mimic human reasoning, thus facilitating the creation of technologies that can understand complex patterns, predict outcomes and suggest actionable insights. This helps businesses forecast future trends, optimize current processes, and automate routine tasks to improve their overall productivity and efficiency. Second, the engineer aims to advance Machine Learning (ML) and AI technologies to increase their efficiency and applicability. By refining the “knowledge” grasped by these technologies, Knowledge Engineers strive to widen the gap between human and machine capabilities, optimizing not just business operations but also impacting daily life and society as a whole.


1. Chatbot Developers/Designers: They use knowledge engineering principles to create intelligent chatbots. These professionals feed their AI systems with knowledge about specific domains (like healthcare, finance, customer support), and then refine the system’s way of processing this knowledge to ensure more accurate responses to user inquiries.2. Health Informatics Specialist: This is another application of knowledge engineering in the real world. These professionals often work in hospitals or other healthcare settings. They use technology to collect, store, and use knowledge effectively for patient care, research, and policy. They may create systems that help healthcare providers easily access a patient’s medical history, helping them make more informed decisions.3. Robotics Engineer: Robotics engineers often need to work with artificial intelligence systems, which involves a significant amount of knowledge engineering. For instance, an engineer might need to build a knowledge base that includes information about not only physical characteristics such as material properties, but also abstract concepts such as cause-and-effect relationships in order for the robot to manipulate its environment.
