Abstract | It is desirable to augment logic programming with the ability to deal with embedded implications, i.e. to allow Horn rules themselves to be goals. But theoretical properties of this kind of logic (which conforms to a subset of intuitionlstic logic) are still being explored, and yet researchers don't come to an uniform acceptable frame work. In this thesis we define two query evaluation procedures for Logic programs containing embedded implications. First we define a simple fixpoint semantics for the definite function-free logic programs with embedded implications and prove some important properties. Then we specify a top-down query answering method, which we call HOLD resolution. Then we define a bottom-up procedure. The soundness and completeness of the two methods are proved. Last, we compare the two methods and propose further work. |
