Question about Piwik log import

Hi, everyone

I had a question about the Piwik log import action page. (Home→Action→Page)
For example, regarding the sreenshot below, here has a few question.

  1. What’s the meaning of the “Others”?
  2. I see this “Others” everywhere, so this “Others” is same data? or common? how did this “Others” be counted?
  3. I got 2115 pageviwe number in jp/library/news/, this number counted in what condition? (how did this number counted)

I will appreciate your kindly hepl.
