101 and 102 matches in CAT tools – what are these percentages?

Confused by 101 and 102 matches in your CAT tool? Read this to understand what your translation memory is up to with these odd percentage matches.

1 min read

When going through a translation memory, a CAT tool may identify some segments as having 101% or 102% matches. Although this looks weird, it is not an error: A 102% match means that not only the current segment is identical to the one stored in the TM, but also the segments before and after it. Respectively, a 101% match means that either the preceding or subsequent segments are identical. Together, these two segments before and after any given segment are referred to as its context.
