Using Term Frequency-Inverse Document Frequency (TF-IDF) vectorization, we evaluate two traditional machine learning classifiers: Multinomial Naive Bayes and Logistic Regression. The results reveal that Sudachi produces tokens closely aligned with dictionary definitions, while MeCab and SentencePiece demonstrate faster processing speeds. The combination of SentencePiece, TF-IDF, and Logistic Regression outperforms the other alternatives in terms of classification performance.","url_abs":"https://arxiv.org/abs/2412.17361v1","url_pdf":"https://arxiv.org/pdf/2412.17361v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"an-experimental-evaluation-of-japanese","repo_url":"https://github.com/arusl/anlp_nlp2021_d3-1","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[{"task_slug":"text-classification","task_name":"Text Classification"},{"task_slug":"regression-1","task_name":"regression"},{"task_slug":"text-classification-1","task_name":"text-classification"}],"methods":[{"method_slug":"bpe","method_name":"BPE"},{"method_slug":"logistic-regression","method_name":"Logistic Regression"},{"method_slug":"sentencepiece","method_name":"SentencePiece"}],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
