Abstract
We propose that in large knowledge bases that are collections of atomic facts
and general rules (Horn Clauses), the rules should be allowed to occur in the
answer for a query. We introduce a new concept of an answer for a query
which includes both atomic facts and general rules. We provide a method of
transforming rules by relational algebra expressions built from projection, join,
and selection and demonstrate how the answers consisting of both facts and
general rules can be generated
