Knowledge engineering is done in the field of artificial intelligence (AI) that attempts to imitate the judgment and conduct of a human master in a given field and help with issues identified with their customized field of information.
A knowledge engineer is an expert whose work is to build up advanced logic into PC frameworks so as to attempt to simulate cognitive tasks of higher level and decision-making in human beings.
Thus a knowledge engineer provides the details of the entire knowledge associated with the built technology.
Therefore, a knowledge engineer tries to find to find out the 'rule of thumbs' thus replacing the task of humans by a computer.
Example of a negative feedback is when your body temperature somehow increased because of the weather, your body will create sweat to lower your body temperature
