# Accuracy Rate (AR)

At Social Bureau, the Accuracy Rate functions as a dynamic measure of **source reliability**, evolving with the user's history of correct verifications. Just as in established frameworks where a source's reliability fluctuates based on performance, here, a user's Accuracy Rate increases with consistent precision, signifying enhanced trust. This evolving metric ensures that every piece of information a user provides is critically assessed over time, maintaining the integrity of the communal database.

Our platform actively encourages users to contribute by reporting or verifying diverse types of information, ranging from video clips to images and documents. Each verification task comes with a specific Contribution Score, indicative of its level of difficulty.

The computation of the Accuracy Rate involves the following steps:

1. When a user reports or verifies tasks, and their work is confirmed by others, they earn an Accuracy Point based on the Task Difficulty Point associated with the type of information.
2. Conversely, if their work is contradicted and proven incorrect by others, an equivalent Accuracy Point is deducted based on the Task Difficulty Point of the information type.

The Accuracy Rate is determined by the following formula:&#x20;

**Accuracy Rate = ((Sum of all Task Difficulty Points − Sum of all Mistake Points) / Sum of all Task Difficulty Points) x 100**

For instance, consider a scenario where a user verifies 2 images (each valued at 15 points) and 2 documents (each valued at 10 points), with a potential reward of up to 50 points. If they lose 15 points due to one incorrect image verification, their Accuracy Rate would be calculated as follows:

&#x20;Accuracy Rate=((50−15)×100/50)=70%

Therefore, the user's Accuracy Rate in this case is 70%, illustrating the percentage of accurate verifications out of their total potential points.

We strongly encourage users to maintain a high Accuracy Rate as it signifies a commitment to precise verifications and valuable contributions to the community, aligning with the core mission of our platform.
