Word Count
Số lượng từ trong văn bản. Trong tiếng Anh, các từ thường được phân cách bằng khoảng trắng.
Đếm từ là tổng số từ trong văn bản. In English, each space-delimited token is counted as one word, though handling of hyphenated compounds and contractions varies by tool. Japanese lacks space-based word boundaries, requiring morphological analyzers (MeCab, Sudachi, etc.) to segment words, making word counting more complex than in English.
Trong SEO, đếm từ đóng vai trò là một chỉ số về chiều sâu nội dung. Data suggests that English articles of 1,500-2,500 words tend to rank higher in search results, and Google's algorithm is believed to indirectly consider word count when evaluating content comprehensiveness. However, more words aren't necessarily better; what matters is providing the right amount of information for the search intent. Japanese SEO typically uses character count (around 2,000-5,000 characters) rather than word count as a guideline. SEO writing guides explain optimal character and word counts.
Bài báo học thuật và báo cáo thường chỉ định "within X words." English academic papers typically range from 3,000-8,000 words, with abstracts often limited to 150-300 words. Microsoft Word and Google Docs have built-in word count features for real-time monitoring during writing. In the translation industry, word count is the basis for pricing, with English-to-Japanese translation typically calculated by multiplying source English word count by a per-word rate.
Có sự chuyển đổi gần đúng giữa số từ tiếng Nhật và tiếng Anh. One English word corresponds to approximately 2-3 Japanese characters, so a 1,000-word English text becomes roughly 2,000-3,000 Japanese characters. This conversion is useful for translation estimates and multilingual content character limit planning.
Phương pháp đếm từ lập trình khác nhau theo ngôn ngữ. Đối với văn bản tiếng Anh, tách theo khoảng trắng bằng text.split(/\s+/).length is basic, but punctuation handling and empty string exclusion require attention. For Japanese text, using morphological analysis libraries or substituting character count is practical. Japanese writing technique books provide detailed character count guidelines.
Về đếm ký tự, đếm từ và đếm ký tự là các chỉ số khác nhau but both measure text "length." English-speaking regions primarily use word count, while Japanese-speaking regions use character count. Displaying word count alongside character count in counting tools enables broader use cases including English content creation and translation estimates.
