An expert system is a knowledge collection combined with an inference engine capable of interpreting queries and chaining together separate items of knowledge to develop new inferences.

Inkqubo yobungcaphephe yingqokelela yolwazi ludityaniswe nenjini yentelekelelo ekwaziyo ukutolika imibuzo kunye nokudibanisa izinto ezahlukeneyo zolwazi ukuvelisa iintelekelelo. Ulwazi olusisizathu esisesona sona olumelwe njengenkqubo yemithetho. Kwezinye imeko, iinkqubo zengcaphephe zingayiphanda intelekelelo yazo ngesinyanzelo, nto leyo echaza izigqibo nengqiqo zazo.
