Sümboolset

Sümboolset is a theoretical construct used in discussions of symbolic computation and formal logic. It denotes a structured set of symbols in which each symbol carries associated attributes and may participate in boolean-valued relations with other symbols. In common formulations, a sümboolset S consists of elements e, each with a label, a type (for example, operator, variable, or constant), and a truth value or a set of truth values. The collection supports operations analogous to standard set operations (union, intersection, difference) and to boolean algebra, allowing combinations of symbols guided by their attributes.

Formally, a sümboolset can be represented as a tuple (E, T, f) where E is a set of elements, T assigns types to elements, and f maps elements to truth values or truth-conditional predicates. Some treatments include a relation R on E to encode adjacency, derivation steps, or semantic links. A sümboolset may be finite or infinite and can be embedded in graphs, matrices, or labeled trees.

The term sümboolset blends "symbol" and "set"; the diaeresis over u is a stylistic choice in some sources. In practice, the concept is used primarily in theoretical or didactic contexts to illustrate how symbolic information can be organized with truth-conditional aspects.

Applications appear in formal languages, symbolic AI, ontology modeling, and verification tasks where it is useful to reason about the presence, absence, or value of symbols within a structured knowledge base. An example use is modeling the set of terminals in a grammar along with their acceptability (true) or rejection (false) under a given derivation.
