Definition of 'Knowledge Engineering'
Knowledge engineering is often used in the development of expert systems, which are computer programs that can mimic the reasoning of human experts in a particular domain. Expert systems are used in a variety of applications, such as medical diagnosis, financial analysis, and customer service.
The process of knowledge engineering typically involves the following steps:
1. **Knowledge acquisition:** The first step is to acquire the knowledge that will be used to build the expert system. This can be done through interviews with human experts, or by mining existing data sources.
2. **Knowledge representation:** The next step is to represent the knowledge in a form that can be used by the expert system. This can be done using a variety of techniques, such as rules, frames, and semantic networks.
3. **Knowledge validation:** Once the knowledge has been represented, it must be validated to ensure that it is accurate and complete. This can be done through a variety of methods, such as testing the expert system on a set of known problems.
4. **Knowledge deployment:** Once the expert system has been validated, it can be deployed to users. This can be done through a variety of methods, such as web-based applications, mobile apps, and desktop software.
Knowledge engineering is a complex and challenging field, but it has the potential to revolutionize the way we interact with computers. By developing intelligent systems that can reason about the world and make decisions, knowledge engineering can help us to solve a variety of problems, such as medical diagnosis, financial analysis, and customer service.
