Abstract

               This study aimed (1) to compare the frequency of content words and function words in a corpus of laboratory animal journals review articles (LARA), and (2) to explore and report the first 100 content words with the highest frequency the LARA corpus. The corpus of LARA included 160 review articles spanning the years 2010 to 2014 from the Journal of the Institute for Laboratory Animal Research (ILAR). The concordance software AntConc Version 3.4.4 (Anthony, 2014) was the research instrument used to investigate the high frequency of content words and function words. The criterion of investigating the high frequency word list was calculated as 80% of the running words (Nation, 2001). The frequency and percentage were used for data analysis. The LARA corpus included 840,773 word tokens and 22,434 word types. The first 2,000 high frequency words were calculated at 83.65% of the running words which consisted of the content words (40.13%). The results revealed that: (1) the frequency of content words (55.85%) was higher than that of function words (44.15%) in the LARA corpus, and (2) the first 100 content words with the highest frequency in the LARA corpus were basic words such as “studies” (ƒ = 3031, 0.36%) and “animal” (ƒ = 2942, 0.35%).
