Câu hỏi thường gặp
Does the keyphrase extractor find multi-word phrases?
No. It counts single words of at least three characters, lowercased, and keeps hyphenated words such as open-source together. Multi-word phrases are not combined, so a phrase shows up as its separate words in the ranking.
How are keywords with the same count ordered?
Words are sorted by occurrence count, highest first, and words with equal counts are ordered alphabetically. The table shows each keyword with its count, and the text output lists the same words separated by commas.
Does the keyword extractor work for languages other than English?
It counts words in any script, because matching uses Unicode letters and numbers. The stopword list is English only, so in other languages common function words are not removed and may appear at the top.
