A sequence of characters
A segment is a unit in a document or other files processed by a computer-aided translation (CAT) tool.
Segment content depends on the type of translated content:
- In a document, a segment is usually a sentence or an equivalent to a sentence.
- In a spreadsheet, a segment is a cell.
- In user interface resource files, a segment can be a menu option, a text on a button, a field label, an error message text, etc.
Segments coupled into source-target pairs are called translation units. Translation units are building blocks of a translation memory. Splitting text into segments allows to apply matches from translation memory and to identify repetitions in an input text.
