摘要:

试卷评分是一项繁忙、耗时耗力的工作,而且在检查中经常受到效率低下和偏见的影响。这个研究项目是一个原始的实验,在自动化的理论答案写在考试中的学生在技术课程,但仍继续被人类评分。在本文中,我们展示了如何使用机器学习中的算法方法来自动检查和评分考试答案中的理论内容。词袋,它们的向量和质心,以及一些语义和词汇文本特征已经被整体使用。机器学习模型已经在根据参加技术课程的毕业生给出的考试手动构建的数据集上实现。这些模型进行了比较,以显示每个模型的有效性。

英文摘要:

Grading of examination papers is a hectic, time-labor intensive task and is often subjected to inefficiency and bias in checking. This research project is a primitive experiment in the automation of grading of theoretical answers written in exams by students in technical courses which yet had continued to be human graded. In this paper, we show how the algorithmic approach in machine learning can be used to automatically examine and grade theoretical content in exam answer papers. Bag of words, their vectors & centroids, and a few semantic and lexical text features have been used overall. Machine learning models have been implemented on datasets manually built from exams given by graduating students enrolled in technical courses. These models have been compared to show the effectiveness of each model.
