The optimalization of cosine similarity method in detecting similarity degree of final project by the college students

Abstract

Technology development makes everything unlimited. Everyone easily to gets information. There are negative and positive impacts. The one negative impact is plagiarism the work of others. Of course this brings a bad impact. This study aims to examine the similarity of Student Final Reports at the Politeknik Unggul LP3M Medan. The method used is the Cosine Similarity Method. This method was chosen because it works based on mathematical calculations. How it works is by comparing the final project done by students with the final project that has been there before. With the Cosine Similitary Method, percentage of similarity will be obtained. If the similarity is high, the final project is said to be tracing.
