It's a "nearly" match May 10, 2004

When you are translating, the CAT tool searches your translation memory to find strings that are similar to the one you are working on.

It may find a string that is identical (this is called an "exact match"). If the string recovered is not quite the same, it is a "fuzzy match".

Here are the definitions from the Trados and Deja Vu manuals, which you can download from the appropriate websites:

Fuzzy Match
A similar, but not identical, match to the
source segment is found in the translation

Deja Vu
A fuzzy match is a source sentence that only partially matches the sentence being sought.

just an inexact match May 10, 2004

An exact match is an identitcal match, which in the CAT context means that an exact (letter for letter, word for word) match to the sentence or phrase to be translated is found in the transltion memory.

A fuzzy match means that something is found in the translation memory that is similar to the phrase or sentence to be translated, but not identical (the idea being that you can change the parts that are different in the translation and still be better off than translating the whole sentence or phrase anew.

It is a business secret Feb 1, 2005

The exact definition of fuzzy match (i.e. how the percentage of similarity between two sentences is calculated) is a business secret of each CAT vendor.
They agree only in the definition of 100%-matches and repetitions.
