An Analysis of Stopwords in Document Classification Tasks with BERT
Yuki Kuwabara, Yu Suzuki (Gifu Univ.) DE2022-14
Abstract (in Japanese) (See Japanese page) 
(in English) When researchers classify documents, they sometimes use stopwords to improve accuracy without checking their effectiveness. We tested the effectiveness of stopwords in improving accuracy in document classification tasks with BERT. We classified documents using different stopwords. We compared the accuracy of the document classification tasks. We did not see a significant improvement in accuracy by removing stopwords. We found that the stopwords we used were not effective for document classification tasks with BERT. We would like to find stopwords that are effective in improving accuracy in document classification tasks with BERT.
