Keywords provided by authors below the Abstracts are of a great significance in research articles. They can enhance data storing and retrival processes. Whereas some studies in the realm of Applied Linguistics provide valuable information about keywords, they have been almost neglected in corpusbased studies. The present study, therfore, aimed at analyzing 249 corpus-based studies published in International Journal of Corpus Linguistics over the past two decades (from 1996 to 2016). The corpus was analyzed in terms of form, relevance and source in four five-year periods. The results showed that the frequency and the structure of the keywords have not changed throughout the period under study. Concerning the relevance, most of the keywords were taken from title and Abstract parts. Regarding the source, the results showed that the keywords pertaining to the target category had the highest frequency. Analysis of the corpus by Landbox software also indicated that over the past two decades, the most frequent keywords were corpus, corpora, analysis, and English. At the end, implications of the findings are discussed.
