We describe two "semantically-oriented" dependency-structure formalisms, t J-forms and S-forms. U-forms have heen previously used in nmchine translation as interlingual representations, hut without being provided with a formal interpretation. S-forms, which we introduce in this paper, are a scoped vet sion of U-fnrms, and we define a composi- tional semantics mechanism for them. Two types of semantic composition are basic: complement incorlgoration and modifier in- corporation. Binding of variables is done at tire time of incorporation, permitting tnttch [lexibility in composition order and a simple account of the semantic effects of permuting several incorporations.
