In Memsource, it is possible to calculate net rates for translation memories, machine translation, and non-translatables (NT). A Project Manager can set up one or more net rate schemes by going to Setup and clicking on Net Rate Schemes in the Financials section. The net rates work independently of any financial information. The number of units for translation (pages, words, or characters) simply gets decreased based on the selected net rate scheme.
Translation Memory Net Rates
Translation memory net rate schemes are well established in the translation industry. These are the main categories:
- Repetition: A segment which gets repeated in a document.
- In-context match: A segment which matches a segment already stored in the translation memory, including its context. That is, the preceding and following segments or context keys match.
- 100% match: A segment which matches a segment already stored in the translation memory.
- Fuzzy match: A segment which partially matches a segment already stored in the translation memory. Fuzzy matches can range from 99% down to zero. However, fuzzy matches below a 75% match rate are often referred to as "new words". That is, they need to be translated from scratch.
Non-translatables Net Rates
- 100% match: A segment which Memsource has identified as content that is very unlikely to require translation, but may need to be checked by a translator.
- 99% match: A segment which Memsource has identified as content that probably does not require translation, but should be checked by a translator.
- Fuzzy match: For the default analysis, NTs would fall only into one of the categories mentioned above. If these are post-edited, they can fall into the fuzzy ranges in terms of Post-editing analysis.
Working with Net Rate Schemes
When a document for translation is imported into a project, it can be analyzed (by carrying out a Default analysis) against the project's translation memories and to identify non-translatables. After opening the analysis, a net rate scheme can be selected, and the pages/words/characters will get recalculated. The results will be displayed in the Net Rate line.
Typically, the Default analysis is generated before the translation.
Machine Translation Net Rates
Memsource makes it possible to measure machine translation quality by comparing machine translation and its final post-edited version at a segment level. The match score is counted in just the same way as for translation memory matches. To analyze the post-edited translation against the initial machine translation, launch the Post-editing analysis via the Analyze button under Project.
After opening a post-editing analysis, a net rate scheme can be selected and the pages/words/characters will get recalculated. The results will get displayed in the Net Rate line.
The post-editing analysis gets typically generated after the translation.
Net Rate calculation example
In this example we will work only with TM matches and see how it affects the number of analyzed words.
Net Rate Scheme settings:
- 0% for 101% TM match
- 10% for 100% TM match
- 100% for less then 50% TM match
Our analyzed job has these matches:
- 15 words in 101% TM match
- 10 words in 100% TM match
- 5 words in less then 50% TM match
The calculation of number of word and the Net Rate percentage: 15 * 0 + 10 * 0.1 + 5 * 1 = 6
