Quality score formula

Quality score formula visualisation and interpretation

1. Account score limit

The highest possible score (100 by default). Can be set on this page: [Evaluation settings]

2. Mistake severity score

Score of mistake by its severity (for example, 1 point for minor and 5 points for major mistakes). Can be set on this page: [Mistake severities list]

3. Mistake type weight

Weight of a specific mistake type by specialization. Can be adjusted on this page [Mistake types list]

4. SUM

A sum of products of #2 and #3 for all the mistakes.

5. Project evaluation word count

Automatic word count: The value from the "Total source words" field in the "Evaluation details" section (not the Total source words of a file). Please see the Automatic vs. manual word count page.

Manual word count: The value from the "Evaluated source words" field (specified when starting the evaluation with a manual word count).

6. 1000

In the end, the result is always converted to 1000, a most optimal value.

The mistake severity scores, mistake type weights, and reports are based on this 1000-word amount. For example, a critical mistake with score of 20 with weight coefficient of 1 reduces the quality score by 20 per 1000 words (by 10 per 2000 words, accordingly, and so on).

Quality score calculation examples

In the examples below, the following quality standard is used:

Automatic word count

‎

File details:

Total source words: 3126

Fully reviewed: yes

Number of units (segments): 392

Project specialization - marketing

Evaluation settings:

Evaluation details:

Total source words: 1749

Source words in corrected units: 1002

Mistakes:

1. Major (3 points each):
   1. Terminology: 1 (weight coefficient 1)
   2. Grammar: 1 (weight coefficient 1.2)
2. Minor (1 point each):
   1. Grammar: 3 (weight coefficient 1.2)
   2. Functional: 2 (weight coefficient 1)
3. Repetitive (0.01 point each):
   1. Functional: 6 (weight coefficient 1)
   2. Layout: 8 (weight coefficient 1)
4. Non-scoring (0 points each):
   1. Style: 5 (weight coefficient 1.2)
   2. Terminology: 3 (weight coefficient 1)

Total mistakes: 29

SUM: 1*3*1+1*3*1.2+3*1*1.2+2*1*1+6*0.01*1+8*0.01*1+5*0*1.2+3*0*1=3+3.6+3.6+2+0.06+0.08+0+0=12.34

Quality score calculation:

100-(12.34/1749*1000)=92.94
