A Role and Reference Grammar Account of Adjuncts in the Airbus Corpus: A Quantitative-Based Study

Abstract

This paper presents the results of a quantitative study of adjuncts in the Airbus corpus carried out within the theoretical framework of Role and Reference Grammar (RRG). We describe the positional behaviour of these peripheral constituents in the Layered Structure of the Clause and postulate scales of positional and peripheral preferences, based on frequency distribution, in the Airbus controlled natural language (CNL). The results obtained were compared with a previous study on adjunct preferences and positions in Natural English to check for changes in these scales due to the nature of the texts written in this CNL. We also aim to contribute to the development of the RRG analysis of adverbials by offering a detailed semantic typology and a description of the syntax of these peripheral constituents grounded in empirical and quantitatively based data that will serve as a basis for the parsing of adverbials in the computational processing of CNLs.
