In particular, due to the COVID-19 pandemic, many countries around the world are increasing the popularity of online education, which makes the research on sentiment classification of course reviews of online education websites an important research direction in natural language processing tasks. Traditional sentiment classification models are mostly based on English. Unlike English, Chinese characters are based on pictograms. Radicals of Chinese characters can also express certain semantics, and characters with the same radical often have similar meanings. Therefore, RSCOEWR, a word-level and radical-level based sentiment classification model for course reviews of Chinese online education websites is proposed, which solves the problem of data sparsity of reviews by feature extraction of multiple dimensions. In addition, a deep learning model based on CNN, BILSTM, BIGRU and Attention is constructed to solve the problem of high dimension and assigning the same attention to context of traditional sentiment classification model. Extensive comparative experiment results show that RSCOEWR outperforms the state-of-the-art sentiment classification models, and the experimental results on public Chinese sentiment classification datasets prove the generalization ability of RSCOEWR.<\/jats:p>","DOI":"10.1093\/comjnl\/bxac144","type":"journal-article","created":{"date-parts":[[2022,11,8]],"date-time":"2022-11-08T14:11:44Z","timestamp":1667916704000},"page":"3000-3014","source":"Crossref","is-referenced-by-count":6,"title":["RSCOEWR: Radical-Based Sentiment Classification of Online Education Website Reviews"],"prefix":"10.1093","volume":"66","author":[{"given":"Jie","family":"Li","sequence":"first","affiliation":[{"name":"Institute of Education, Guizhou Normal University , Guiyang, Guizhou 550025, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"GuoYing","family":"Sun","sequence":"additional","affiliation":[{"name":"Faculty of Computing, Harbin Institute of Technology , Harbin, Heilongjiang 264209, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2022,11,6]]},"reference":[{"key":"2023121811454791300_ref1","first-page":"603","article-title":"Natural language processing","author":"Chowdhary, KR1442","year":"2020","journal-title":"Fundamentals of artificial intelligence"},{"key":"2023121811454791300_ref2","doi-asserted-by":"crossref","first-page":"209","DOI":"10.1016\/j.eswa.2018.09.009","article-title":"Monitoring the public opinion about the vaccination topic from tweets analysis","volume":"116","author":"D\u2019Andrea","year":"2019","journal-title":"Expert Systems with Applications"},{"key":"2023121811454791300_ref3","doi-asserted-by":"crossref","first-page":"129","DOI":"10.2747\/1538-7216.47.2.129","article-title":"The geopolitical orientations of ordinary Russians: A public opinion analysis","volume":"47","author":"O\u2019Loughlin","year":"2006","journal-title":"Eurasian Geogr.
