Abstract
Authors develop the report similarity judgment system using the natural language processing on course management system "Moodle". There is a vector analysis that uses TF, IDF as an algorithm of the report similarity judgment. However, this method has the problem in implementation. Authors develop newly the similar judgment method that used Bloom Filter.
In this paper, Authors explain the similar judgment algorithm by the vector analysis. Afterwards, authors propose the similar judgment algorithm by Bloom Filter. At last we describe the simulation results using both method.
