Segmentation Task

A Segmentation Task is a data processing task that requires the division of a complex data item into (typically homogeneous) segments.

• Context:
  • Input: a Complex Input.
  • output: a set of Subsets.
    • optional: a Segmentation Function and a Segmentation Confidence Function.
  • It can be solved by a Segmentation System (that implements a Segmentation algorithm).
  • It can range from being:
    • a Sequence Segmentation Task.
    • a Tree Segmentation Task.
    • a Lattice Segmentation Task.
    • a Graph Segmentation Task.
• Example(s):
  • a Text Segmentation Task, such as a Text Chunking Task.
  • a Speech Segmentation Task.
  • a DNA Segmentation Task.
  • an Image Segmentation Task.
  • …
• Counter-Example(s):
  • a Sequence-Member Labeling Task, such as a POS tagging task.
• See: Detection Task, Recognition Task.
