WebType inference and prolog program evaluation are both (very simple) theorem provers. Both proceed by trying to unify (the same term is used) free variables in statements they are trying to prove with other statements that either have been proven or might be proven.

"WebProlog has a built-in backward chaining inference engine which can be used to partially implement some expert systems. Prolog rules are used for the knowledge representation, and the Prolog inference engine is used to derive conclusions. Other portions of the system, such as the user interface, must be coded using Prolog as a programming language. " - Prolog type inference
