Understand TM match scores

When Taia finds a similar segment in your Translation Memory, it assigns a match score (0–100%) that tells you how closely the stored translation matches the current segment. Higher scores mean less editing is needed.

Score ranges​

The score compares the two sentences character by character, so a changed number or a different word ending costs a few points, and a rewritten sentence costs a lot.

ScoreLabelWhat it means
100%Exact matchThe text is identical. Extra spaces are ignored
95–99%Near-exact matchA few characters differ, such as a number or an ending. A match that differs only in capital letters always shows as 99%, never 100%, so it can't be applied automatically
75–94%Fuzzy matchWord-level differences; requires review
Below 75%Not suggestedThe editor only shows Translation Memory matches of 75% and above

There is also a special type of match called an in-project match: the same or similar text elsewhere in the same project. The editor lists these separately under In-project matches (60% and above, up to five), so they don't compete with your Translation Memory.

How match scores affect price​

For Professional Translation orders, segments with high TM match scores cost less per word because the linguist has less work to do:

  • 100% matches and repetitions are charged at a reduced rate
  • Fuzzy matches (75–99%) are charged at a mid rate
  • Below 75% and new text are charged at the full rate

The quote analysis splits the file into these bands (100%, 95–99%, 85–94%, 75–84%, 50–74% and new), so you can see them before you confirm an order.

Match scores in the CAT editor​

In the CAT editor's Translation Memory sidebar, each suggested match shows its score as a badge. The badge and the card's edge are green for 100%, blue for 95% and above, and yellow for 75% and above.

A Translation Memory match card with a green 100% match badge. The source sentence is identical to the segment and the French target is shown below. A Translation Memory match card with a blue 98% match badge. The source is shown as a diff: the number 350 is struck through and 400 is underlined as the change. A Translation Memory match card with a yellow 88% match badge. The source is shown as a diff: Third is struck through and Fourth is underlined as the change.

Lower than 100%, the card shows the source as a diff against your segment, so you can see exactly what changed. To use a match, click the copy icon on the card (its tooltip reads Insert translation), or press Ctrl+1, Ctrl+2 or Ctrl+3 for the first, second or third match. Then edit as needed.
