# Supervised Sequence-Member Classification Task

(Redirected from Supervised Sequence-Member Labeling)

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.
- …

**Counter-Example(s):****See:**Supervised Classification Task.

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