Notes on the Organization of the Environment of a Text Generation Grammar. ISI Reprint Series
Taking the lexicogrammatical resources (i.e. the vocabulary and syntax) of English as a starting point, this report explores the demands those resources put on the design of the part of a text generation system that supports the process of lexicogrammatical expression. The first section of the report notes that a reason for using the lexicogrammar to infer the organization of other parts of the system is that more is known about lexicogrammar than about the organization of other parts, because of accounts by functional linguists. The second section discusses the interface between grammar and environment (the knowledge base and discourse model) and focuses on its organization. Functional decomposition of grammar and environment is investigated in the third section, which includes a discussion of metafunctions in the grammar (experiential, logical, interpersonal, and textual). The fourth section deals with the knowledge base of a text generator, and includes discussion of how semantic types and grammatical classes are related and how phenomena are classified. Additional topics in this section are: (1) the (logical) sequential organization of supercomplex phenomena; (2) the (experiential) configurational kind of organization of configurations; (3) correlations between taxonomies in the knowledge base; and (4) metaphor. The discourse model and its components (theme, conjunction, and determination) is examined in the fifth section, while the sixth section presents specific examples and summary. Notes and references conclude the report. (SKC)
