Abstract: The study on agglutinative-language-involved Semantic Accessibility Scale（SAS） based on Japanese corpus comprises three steps.Firstly，『ゆきぐに』 is extracted from corpus and divided into six groups for comparison by the systematic random sampling skill in which different equidistant extraction is included.Secondly，the definition of word height in presently-verified SAS formula reflecting inflecting language domain is adapted for agglutinative language domain.The word beyond five music beats is called the unpopular one，and the number of this kind of word every 100 words is considered word height.Finally，a conclusion is drawn that decreasing extracted-space results in increasing Sampling Ratio（SR），and that the non-relevance between SR and SAS is verified by the schema in which the contrast between increasing SR and the mean-fluctuated SAS is involved.In short，the evaluation of SAS in inflecting language text can be applicable in other fields，including agglutinative language text.
