Abstract

Sorted term-position algebras are an extension of term algebras. In addition to sorted terms with constructor and selector functions, they provide term positions as algebra elements and functions that relate term positions. This paper describes possible applications of term-position algebras and investigates their formal specification in existing specification frameworks. In particular, it presents an algebraic specification of term-positions in Casl and in a higher-order logic.
