Validation & Verification With Knowledge Engineers
Validation is the process of ensuring that something is correct or conforms to a certain standard. A knowledge engineer is required to carry out data collection and data entry, but they must use validation in order to ensure that the data they collect, and then enter into their systems, fall within the accepted boundaries of the application collecting the data.
It is important that a knowledge engineer incorporates validation procedures into their systems within the program code. This means that when a user enters information into the system, mistakes will not be made. For example, if the expert system asks for a ‘yes’ or ‘no’ answer, it is up to the knowledge engineer to include code in the program that will stop the user from entering any information other than a yes or no answer. Another example is if the user is asked to enter their surname, the knowledge engineer will need to incorporate a validation procedure that causes the program to validate that only letters are entered and not numbers.

Famous quotes containing the words verification and/or knowledge:
“Science is a system of statements based on direct experience, and controlled by experimental verification. Verification in science is not, however, of single statements but of the entire system or a sub-system of such statements.”
—Rudolf Carnap (1891–1970)
“There is evidence that all too many people are approaching parenthood with a dangerous lack of knowledge and skill. The result is that many children are losing out on what ought to be an undeniable right—the right to have parents who know how to be good parents, parents skilled in the art of “parenting.””
—T. H. Bell (20th century)
