### Abstract

Introduction Many of the formalisms used to define the syntax of natural (and programming) languages may be located in a continuum that ranges from propositional Horn logic to full first order Horn logic, possibly with non-Herbrand interpretations. This structural parenthood has been previously remarked: it lead to the development of Prolog [Col-78, Coh-88] and is analyzed in some detail in [PerW-80] for Context-Free languages and Horn Clauses. A notable outcome is the parsing technique known as Earley deduction [PerW-83]. These formalisms play (at least) three roles: descriptive: they give a finite and organized description of the syntactic structure of the language, analytic: they can be used to analyze sentences so as to retrieve a syntactic structure (i.e. a representation) from which the meaning can be extracted, generative: they can also be used as the specification of the concrete representation of sentences from a more

Such proof forests may be obtained by the same techniques that we used for CF parsing =-=[BilL-89]-=-. However it is not yet fully clear how parse trees or derivation trees may be extracted from the proof forest when DC programs are used to encode non-CF syntactic formalisms.

On the basis of our experience with TAGs, we conjecture that for non-CF formalisms, the proof forest obtained corresponds to derivation forests (i.e. containing derivation trees as defined in =-=[VijWJ-87]-=-) rather than to forest representing the possible superficial syntactic structure of object trees. 5 Concluding Remarks Our understanding of syntactic structures and parsing may be considerably enhanc... |
