Question
You analyzed a document with Text Analytics service and discovered that the language used is English, having a confidence score of 0.8. What does that mean?
A. The predominant language in the text is English
B. A small amount of the text is in English
C. Only 80% of the text was analyzed
Answer
A. The predominant language in the text is English
Explanation
When the confidence score is less than 1, it means that the analyzed text is in mixed language. A confidence score of 0.8 means that the Text Analytics service is 80% confident that the main language detected is English, but some other languages were possibly detected.
The correct answer is A. The predominant language in the text is English. This means that the Text Analytics service has detected that the majority of the text is written in English, and it has assigned a confidence score of 0.8 to this detection. A confidence score is a numeric value between 0 and 1 that indicates how certain the service is that the identified language is true. Scores close to 1 indicate high certainty, while scores close to 0 indicate low certainty. Therefore, a score of 0.8 means that the service is fairly confident that the text is in English, but not 100% sure.
