What is LQA?

The LQA (Language Quality Assurance) feature is a translation quality scoring system that is based on the Multidimensional Quality Metrics (MQM) model which has been designed as part of the QT Launchpad project. For more information about MQM, see: MQM.

We recommend that you read this article, which contains a step-by-step guideline to activating and performing the LQA step: How to perform LQA.

As a user with the Administrator role, go to Configuration → Settings →  LQA → LQA, where you can select the full list of issues or any subset of them. You can also set the weight for each item and severity multiplier for minor, major and critical items:

...

Apart from that, you can always specify if you would like to base your LQA score on the source or target word count in Configuration → Settings → LQA → LQA Options:

LQA calculation method

...

TS = 1 - ( AP / source or target Word Count )

Example: Imagine a project with a file containing 200 words. We translate everything and impose two LQA errors in two different segments: Accuracy (Minor); Grammar (Major);

3.

Considering that: a) weight of all LQA errors = 1; b) severity for Minor = 1, and for Major = 5. Penalty (P) score for this project is: P = ( 1 x 1 + 1 x 5 ) = 6 Adjusted Penalty (AP) score for this project is: AP = 6 x 1 = 6 Total (TS) score for this project is: TS = 1 - ( 6 / 200 ) = 0.97 = 97%
