The E-Framework: Emerging Problems

Beth & Nygaard (1988) have described a formalism for NLP, the E-Framework (EFW). Two kinds of problem are emerging. Formally, there are problems with a complete formalisation of certain details of the EFW, but these will not be examined in this paper. Substantively, the question arises as to what mileage there is in this formalism tbr the MT problem. Possibly this question arises about any new NLP formalism, but Raw et al (1988) describe the EFW in an MT context. The EFW arose in reaction to the CAT forrealism for MT (Arnold & des Tombe (1987), Arnold et al (1986)). This was a sequential stratificational formalism in which each level of representation was policed by its own grammar. The essentials of this process can be diagrammed:
