IDF Score Vector
A IDF Score Vector is a real vector that represents the IDF score of each member [math]\displaystyle{ t }[/math] within a multiset space [math]\displaystyle{ C }[/math] (often a text corpus).
- Context:
- It can be represented a [math]\displaystyle{ [\text{IDF}(t_1,C), \text{IDF}(t_2,C), ..., \text{IDF}(t_n,C)] }[/math], where ...
- It can be used by a IDF-based Distance Function/IDF Vector Distance Function.

- Example(s):
- [math]\displaystyle{ \text{IDF}_{\text{vector}}(\text{Corpus}_C) = [(``red",0.187...), (``chrome-plated",0.002...), ..., (``\text{zoo}",0.012)] }[/math].
