no dictionary has it explicitly as an adverb, just saying things like 副詞的にも使う.  i'd say n-adv.  there is some consistency about that, i think

also, i don't think the 〜は version is an adverb is it?  it's just raising a noun, right?

There is no consistency. A major clean-up is needed.
Your questions about the PoS tags seem like a good topic for the mailing list.

It was my assumption that [adv] is used for regular adverbs (e.g. 必ず), [n-adv] is used for nouns that can function as adverbs (e.g. 半分), and [n-t] is used for time-related nouns that can function as adverbs (e.g. 今日, 来月).

But going by these definitions, there is no consistency whatsoever in the database. 一切 is tagged n-adv but 全て is tagged adv, 一部 is tagged n-adv but 全部 is tagged n-adv *and* n-t. 前日 is tagged both n-adv and n-t but 翌年 only n-t.

Until someone explains to me what exactly adv, n-adv, and n-t are supposed to mean, I can't use them with any confidence.

Perhaps Jim can chime in?

daijs: 副詞的にも用いる

Robin, I think the correct adverbial usage really is 大半は, but particles are often dropped.
I'd be happy with [n-adv] as well.
