HPSG-neutral notation for LRS
Metavariables: α, β, ɣ, ..., φ, ψ, ...
Contribution constraints:
- call(x)
The semantic representation of a sign with a contribution constraint of the form call(x) must be an expression containing call(x) as a subexpression - ¬α
The semantic representation of a sign with a contribution constraint of the form ¬α must be an expression containing ¬α as a subexpression where α can be any expression.
Embedding constraints:
- α[call(x)]
The metavariable α is any expression containing call(x) as a subexpression.
Combinatorial semantics
When two signs combine,
- all constraints on the combining signs' semantic representation also apply to the resulting combination, and
- additional constraints may be added through principles of grammar.
