What is alignment?

Alignment is a procedure used to generate translation memories from pairs of source documents and their translations, called target documents.

Alignment usually involves three steps:

  • Software, usually referred to as an aligner or alignment tool, automatically segments the source and target documents, aligns (pairs) the source and target segments and displays the result, typically in a table.
  • A linguist checks the result and corrects misalignments.
  • Once all segments are properly aligned, the software aligner generates a translation memory containing all the aligned segment pairs as translation units (TUs).

The reliability of automatic segmentation and alignment depends on both the aligner and the level of similarity in linguistic structures and document formatting between the source and target documents. With larger documents, the human part of alignment can be tedious and time-consuming, unless the result of automatic alignment is near perfect.
