A Supervised Sequence-Member Classification Task is a sequence-member classification task that is a supervised classification task.

**AKA:**Supervised Labeling, Supervised Sequence Tagging.**Context:**- It is a type-of Supervised Structured-Input Classification Task.
- It can be solved by a Supervised Sequence-Member Classification System (that implements a supervised sequence-member classification algorithm).
- It can be used to solve a Supervised Chunking Task (e.g. with BIO tags).

**Example(s):**- a Supervised Text Tagging Task, such as supervised POS tagging.
- …

- QUOTE: In the sequence labeling setting, instances [math]\displaystyle{ x }[/math] belong to a general input space [math]\displaystyle{ \mathcal{X} }[/math] and conceptually are composed of a finite number [math]\displaystyle{ n }[/math] of components, such as words of a sentence. The number of components [math]\displaystyle{ n = |x| }[/math] varies between instances. Each part of a instance is labelled from a finite set [math]\displaystyle{ \mathcal{Y} }[/math], [math]\displaystyle{ |\mathcal{Y}| = K }[/math]. That is, a labeling of an entire instance belongs to the product set [math]\displaystyle{ y \in \mathcal{Y} × \mathcal{Y} ... \mathcal{Y} }[/math] ([math]\displaystyle{ n }[/math] times).
