RANCANG BANGUN APLIKASI PENILAIAN ESAI OTOMATIS MENGGUNAKAN ALGORITMA COSINE SIMILARITY STUDI KASUS MTS PERGURUAN MU’ALLIMAT
Abstract
This study aims to design and develop an automatic essay scoring application using the Cosine similarity
algorithm, with a case study at MTS Perguruan Mu’allimat. The main objectives of this research are to
understand the process of creating an automatic answer correction system and to explore the application of
the Cosine similarity method in the automatic essay answer correction system. The research begins with
designing the system based on Object Oriented Programming (OOP) principles according to the system
requirements analysis. The implementation of the Cosine similarity algorithm is conducted to calculate the
similarity between students' answers and the correct answers. The results indicate that using the Cosine
similarity algorithm in essay answer correction facilitates grading with reasonably good accuracy. By
testing 10 student answers, the algorithm achieves an accuracy rate of 75.11% compared to manual
calculations. From these results, it can be concluded that this system is effective and accurate in scoring
essay exams, and thus can be widely implemented to improve grading efficiency in educational settings.
Keywords: essay grading application, Cosine similarity, automatic correction.
