Knowledge Engineering is a field related to artificial intelligence. The main work of a knowledge engineer is to develop programs that can extract knowledge from information. The engineers are trained in expert systems. They are employed to break down the information which has been provided by domain experts into simpler and easily communicable form. Good knowledge of computer science and logic are essential qualities to become a successful knowledge engineer.

I would like to list some important interview questions that are asked in an interview of a knowledge engineer:

1. List the principles of knowledge engineering.
The principles of knowledge engineering are listed as under:

• Knowledge engineers acknowledge that there are different types of experts and expertise.
• There are different types of knowledge and each demands an appropriate technique.
• There are different ways of representing knowledge which can aid its validation and acquisition.
• Knowledge can be used in different ways and should be interpreted according to the aim of the project.
• Structured methods should be used for acquiring knowledge.

2. Point out the difference between data mining and statistics.
Data mining involves extraction of knowledge by reading patterns of data. Statistics is the core of data mining. It helps in differentiating in between random and significant findings.

3. What are the main views of knowledge engineering?
Two main views of knowledge engineering are:

• Transfer View – It involves application of conventional techniques of knowledge engineering. It is a traditional approach.
• Modeling View- It involves modeling of the knowledge and problem solving techniques of domain expert into artificial intelligence system.

4. What are Decision Support systems?
Decision support system is an integration of software and hardware applications that collectively help in taking a decision. It is a data driven system that analyzes the data to acquire the knowledge and information.

5. What qualifications do you have for this job?
Tell about your relevant qualifications. Your interest in computational intelligence and artificial intelligence will help you a lot. You can also tell about your knowledge in programming languages like SGML, XML, HTML, Document type definition, Extensible Style- sheet Language and various other web tools. Knowing about JavaScript, Visual Basic for applications, networking and UNIX field will be an added advantage. An experience of working in IT sector will add value to your answer.

These are some of the important interview questions that are asked by an employer. All the best!
