Segmentation is the processing of splitting the input into processing units. In UNLization with IAN, the natural language input document is split into sentences; in UNLization with SEAN, the natural language input is split into texts; in NLization with EUGENE, the UNL input is split into graphs.

IAN

In IAN, segmentation is done using a set of predefined* sentence boundaries:

  • punctuation signs: ".",";","!","?","..."
  • special characters: end-of-line, end-of-paragraph

* This process is expected to be replaced by a user-defined system in the coming releases of IAN.

EUGENE

In EUGENE, segmentation is done using the UNL document tags.

  • The tag [S] defines the beginning of a sentence, and the tag [/S] defines the end of a sentence
  • The tag {org} defines the beginning of the source sentence, and the tag {/org} defines the end of the source sentence
  • The tag {unl} defines the beginning of the UNL graph, and the tag {/unl} defines the end of the UNL graph
