چکیده انگلیسی

This study investigated rhetorical functions and their associated linguistic realizations in English review article abstracts. The analysis was based on a corpus of 100 English review article abstracts from linguistics and applied linguistics disciplines and followed a corpus-driven discourse analytic top-down approach. MAXQDA and WordSmith were used to code the moves and analyze their associated sub-corpora, respectively. The results of calculating range and frequency distributions showed that English conceptual review article abstracts use a rhetorical structure, different from that of research paper abstracts. This rhetorical organization is realized through a different set of moves, namely 1) establishing the territory or area of study, 2) identifying the problem, 3) introducing the present research, 4) organizing the paper, and 5) concluding or reflecting. Moreover, each move was realized through a distinct set of sub-moves. In terms of range, the moves dealing with purpose and structure were the most widely present moves; in terms of frequency distribution, the move dealing with structure was the most frequent. Furthermore, the highly frequent use of plural self-mentions indicates that in review article abstracts the emphasis is on research as a group activity inclusive of the researcher(s) and objects of study. In addition, the presence of ‘establishing the territory’, together with ‘identifying the problem’ can be seen as an attempt to sell the research. Finally, the prevalent use of the five moves showed that most review article abstracts are indicative-informative in function
