Which specific tags are not considered by API Untagged

When I was using the Batch page, I noticed that “Archives with no tags have been pre-checked”, but some of mangas have already been set tags artist/group/series. Which specific tags are not considered?

$has_tags = 1 unless $t =~ /(artist|parody|series|language|event|group|date_added|timestamp):.*/;
