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.
