使用特征提取技术的分类方法进行学生情感分析

Student sentiment Analysis Using Classification With Feature Extraction Techniques

Latika Tamrakar, Dr. Padmavati Shrivastava, S. M. Ghosh

AI总结:

本文研究基于网络学习中的学生反馈情感分析,使用LR、SVM、NB和DT四种机器学习模型,并结合CVr/BoW与TF-IDF两种特征提取技术,在清洗后的SFB数据集上提升分类准确率。

摘要:

技术进步通过将技术引入课堂并提升学习体验,推动了教育系统中的诸多变革。如今,基于网络的学习正变得越来越受欢迎。本文描述了基于网络的学习及其对学生的有效性。教育或学习系统中的一个主要因素是反馈;如果能够有效利用,反馈对学习是有益的。在本文中,我们研究了如何将逻辑回归(LR)、支持向量机(SVM)、朴素贝叶斯(NB)、决策树(DT)等机器学习技术应用于基于网络的学习,重点放在学生反馈中存在的情感上。我们还研究了两种类型的特征提取技术(FETs),即计数向量(CVr)或词袋(BoW)以及词频-逆文档频率(TF-IDF)向量。在本研究中,我们的目标是让我们提出的LR、SVM、NB和DT模型在清洗后的数据集和特征提取技术的基础上,以更高的准确率对学生反馈数据集(SFB)中的情感存在进行分类。SFB是学生情感分析中的重要关注点之一。

英文摘要:

Technical growths have empowered, numerous revolutions in the educational system by acquainting with technology into the classroom and by elevating the learning experience. Nowadays Web-based learning is getting much popularity. This paper describes the web-based learning and their effectiveness towards students. One of the prime factors in education or learning system is feedback; it is beneficial to learning if it must be used effectively. In this paper, we worked on how machine learning techniques like Logistic Regression (LR), Support Vector Machine (SVM), Naive Bayes (NB), Decision Tree (DT) can be applied over Web-based learning, emphasis given on sentiment present in the feedback students. We also work on two types of Feature Extraction Technique (FETs) namely Count Vector (CVr) or Bag of Words) (BoW) and Term Frequency and Inverse Document Frequency (TF-IDF) Vector. In the research study, it is our goal for our proposed LR, SVM, NB, and DT models to classify the presence of Student Feedback Dataset (SFB) with improved accuracy with cleaned dataset and feature extraction techniques. The SFB is one of the significant concerns among the student sentimental analysis.
