A partial implementation of the grammatical stratum of organisation found in Systemic Functional Grammar (SFG) provides the core of Penman's linguistic capabilities (Mann and Matthiessen, 1985) , whereas there is a strong input from SFG in the semantic interpretation of ET-D's dependency structures (Steiner, Schmidt and Zelinsky-Wibbelt, 1988) . It is therefore also one of the motivations of this cooperation to investigate the potential of SFG as a tool for transfer in machine translation MT, and in the wider context of systemic-functional linguistics also as a theoretical environment and as a formalism for ex-pressing semantics. This should be of interest to a wider audience within computational linguistics, especially as SFG has recently been attracting an increasing amount of interest in the field (see, e.g.: Houghton and Isard, 1987; Kasper, 1988; Patten, 1988; Patten and Ritchie, 1987; Mellish, 1988 ; Paris and Bateman, 1989 ).", |

The essentials of the Eurotra-D approach are to be found in Steiner, Schmidt, and Zelinsky-Wibbelt (1988). The Eurotra system is a transfer-based multi-lingual MT-system. It is stratificational in the sense that analysis and synthesis proceed through two syntactic levels (configurational and functional) and one semantic level, called the Interface Structure (IS). These interface representations are semantically interpreted dependency structures; they are described in more detail in Section 3.3. Each level is defined by a level-specific grammar and a lexicon. The connection between adjacent levels is established with translator-rules which define a treeto-tree mapping between level representations. The main operation involved in the mapping is unification, i.e. the unification between already built objects and rules. Transfer between two languages takes place as a translation between the interface level representations of the source language (SL) and the target language (TL).", |

Penman has been designed to be a portable, reusable text generation facility which can be embedded in many kinds of computational systems. The linguistic core of Penman is Nigel (Mann and Matthiessen, 1983 ), a large systemic-functional grammar of English based on the work of ttalliday (1985) with contributions made by several other systemic linguists. Nigel is a large network of interdependent points of minimal grammatical contrast, called systems. Each of these systems defines a collection of alternatives called grammatical features. The semantic interface of the Nigel grammar is defined by a set of inquiries that control choices of grammatical features by mediating the flow of information between the grammar and external sources of information.", |

The upper model is typically used to mediate between the organisation of knowledge found in an application domain and the kind of organisation that is most convenient for implementing the grammar's inquiries. We have made crucial use of the upper model in constructing our combination of the two components. In effect, the upper model can often mediate between the results of the MT analysis, expressed in ET-D Interface Structures, and the input that must be specified for Penman, expressed in the Penman Sentence Plan Language (SPL) (Kasper, 1989) . Each of these information sources, the upper model, the Penman SPL, and the ET-D Interface Structures will now be described in detail.", |

| "text": "Perhaps the crucial task for text generation is to be able to control linguistic resources so as to make the generated text conform to what is to be expressed. In Penman this is the responsibility of the grammar's inquiry semantics. Furthermore, a large subset of Penman's inquiries are taxonomic. These relate particular instances of what is to be expressed to the categories of semantic organisation that the grammar's semantics requires. These categories, and the relationships among them, constitute the upper model. The upper model serves to organize the propositional content that needs to be expressed in text; in systemic-functional linguistics, this range of meaning is called ideational. Many ideational.inquiries can be expressed in terms of the classifications of concepts that the upper model provides. These classifications form an inheritance hierarchy that organises concepts according to how they may be expressed in English. Thus, when an application domain for which Penman is to generate language connects its concepts to those of the upper model, a single inheritance hierarchy is formed from which the grammar's inquiries can determine information about how any particular domain concept may be expressed in English. We refer to this single inheritance hierarchy formed from the application domain model and the upper model as the combined model. Inquiries that need to determine whether an application domain model concept belongs to the class defined by some upper model concept can then rely on simple inheritance inferences. For example, this type of inference allows Penman to ascertain that a domain entity is a process, rather than an object, and so should be expressed as a verb rather than as a nominal phrase. Much finer distinctions are drawn by the actual upper model, which currently contains approximately 200 concepts.", |

SPL expressions are lists of terms describing the types of entities and the particular features of those entities to be expressed in English. The types of SPL terms are interpreted with respect to the knowledge base of general conceptual categories defined in the upper model. When the concepts of Penman's upper model are instantiated by more specific concepts from an application program's knowledge base (i.e. world knowledge specific to the domain of the application), then application concepts can be used directly in the SPL expression. The features of SPL terms are either semantic relations to be expressed, drawn from the relations]roles defined by the combined model or direct specifications of responses to Penman's inquiries. This latter possibility provides for the input of information from other sources of knowledge known to be necessary for controlling generation, e.g. text planning information and speaker-hearer models. These types of meaning fall outside the kind of taxonomic, 'ideational' meanings defined in the upper model and so require separate treatment. Currently we specify information of this type as direct responses to Penman's inquiries since the inquiries are not limited to ideational meanings.

Thus, the features expressing definiteness in IS are mapped into inquiry responses giving information about whether a given phrase is identifiable; those features expressing number are mapped into responses concerning whether the concept is to be expressed as a single entity or as several distinct entities. These are some of the semantic dimensions around which NigeI organises the selection of determiners and quantifiers in English (for a fuller account of Nigel's treatment, see: Bateman and Matthiessen, 1988 ; also, for an account of the ET-D approach, see: Steiner, Winter and Zellnsky-Wibbelt, 1987).

| "text": "Another area which is translated in this way in the present system is the area of time. Both the Eurotra appr~ch to time (cf. van Eynde, 1988) and the Nigel approach (cL Matthiessen, 1984 ) grew out of a critical appraisal of the Reichenbachian framework, although they took quite different directions from there, with Mar~hiessen following essentially SFG lines. Still, enough common ground has been preserved in order to make a transfer of ET-D time features (i.e. semantic), rather than tense features (morpho-syntactic), an interesting and possible enterprise. Tenses encode complex relationships between time of speaking, reference time, and time of event, in interaction with Adverbiais in particular, and it is only with the help of a type of transfer that gives access to this level of detail that we can arrive at the English 'present perfect tense' as a translation of the German 'present' plus a time adverbial. For example, in Figure 1 Figure 2 . While we are not claiming that a direct mapping of tenses into tenses in SL-TL transfer is necessarily impossible, it would seem considerably more complex and translationally implausible than encoding the meaning expressed by tenses, as we have done here in terms of inquiry responses.", |

This type of transfer is very close to the idea of IS =~ IS transfer in Eurotra, but is used sparingly in the present application. Most of the morpho-syntactic features present in the IS representations do not need to be used directly since the semantic features give sufficient and more appropriate information for translation.", |

| "text": "Combining the resources of the ET-D German analysis component with the Penman English generator has created an interesting research environment for asking questions about transfer strategies in MT. As is well known, the transfer process in an MT environment places complex requirements on both the linguistic theories involved and on the theories of translation. Perhaps the most refreshing aspect of the endeavour has been the new perspective which one gets on old problems, which suddenly seem to lose the air of having a range of often tried and well known, but essentially unsatisfactory solutions. One whole class of questions relates to what should be preserved in a translation process, as different from, say, processes of paraphrasing or summarising. One possible answer to this is that what needs to be preserved at least is the truth value of sentences and their translations. While this may serve as a useful bottom line from which to start, it has long been recognised to be no more than that. Many researchers argue that we also need to preserve the essential features of thematic structure and information structure. For most projects at this time, this problem is difficult to address because the linguistic models embodied in them do not foreground that type of information, ttowever, with ET-D's interest in topic and focus, and with Nigel's fairly comprehensive treatment of theme, there is a very immediate way of making these aspects of linguistic information an accessible part of the translation process. In the translation pair represented by Figures 1 and 2 , for example, we can see that the IS s~mantic feature top=yes indicating thematic prominence have been transferred into the inquiry response specification :circumstantial-theme-q(S9 H1) context. This calls for the grammar to prepose the constituent realising $9, i.e. the Since-clause, into sentence-initial thematic position, rather than letting it appear later in the sentence as it would when non-thematic.", |

The basic form of the translation process is to transfer ET-D IS representations into Penman SPL representations. As ET-D IS and Penman SPL representations are both feature-based dependency structures, the formal aspects of the transfer from ET-D IS into Penman SPL are not very complicated. Determining an appropriate mapping for the content of particular values within ET-D IS representations is by far a more challenging aspect of this translation process." |
