Metadiscourse markers and their importance to academic writing are essential research subjects nowadays. The current corpus-based study aims at identifying interactional and interactive metadiscourse markers in terms of frequency and function in the abstract section of published research articles in applied linguistics developed by Algerian, Saudi, and Native researchers. 20 research articles for each group, with a total of 60 articles have been randomly selected and compiled as the research corpus for this study, then analyzed qualitatively and quantitatively using AntConc.3.2.4 relying on Hyland’s classification of metadiscourse markers. As a comparative study, the research considered the abstracts written by natives as a benchmark and attempted to find an answer to the main inquiry related to the frequency of use of metadiscourse devices by Algerian and Saudi researchers in comparison to their Native counterparts. The main research results showed how close were Algerian abstracts to native ones in terms of using endophorics, frame markers, code glosses, hedges, attitude markers, and self-mentions. While Saudi abstracts were close to the benchmark only in two markers that are transitions and engagement markers. The rest of the devices were shown to be far from the native norm in both cases. The findings also revealed that the use of metadiscourse markers is not the only indicator of papers’ publication rate in indexed journals by comparing the corpus analysis results to the source of the articles (journals), to find that even if Algerian researchers publish less in high indexed journals in comparison to Saudis, they are still closer in using markers to the natives as a benchmark.
