Setting the Custom Image Risk Library

Last updated: 2024-03-25 15:01:26
Overview
The custom image risk library is designed to help you manage images or keywords that need to be moderated. With risk library customization, you can configure the images or keywords to allow or block them. This can be applied to all moderation scenes.
Image Risk Library
You can use an image risk library to manage images that need to be blocked or allowed, to address unexpected control requirements.
Six preset image risk libraries are available in the system:
Normal image library: The returned moderation result will be normal for images that match those in this library.
Pornographic and illegal image library: The returned moderation result will be the corresponding violation tag for images that match those in the library.
Creating new image risk library is not supported. You can add sample images to the existing default libraries.
Note:
The image risk library is effective by account. After you add sample images to the gallery in any bucket under the same account, these images will automatically take effect in all your buckets and all your moderation policies.
A single image library can contain a maximum of 10,000 sample images.
Some specific images may fail to be added to the image library. In this case, please contact us for assistance.
Text Risk Library
You can use the text risk library to manage text to be blocked or allowed, in order to address sudden control requirements.
The text risk library contains the following types:
Pre-defined text library: It is a text library with pre-defined policies for you, which includes:
Normal text library: If a keyword in the library is matched, the moderation result will be returned as normal.
Pornographic text library, illegal text library, and other text libraries: If a keyword in the library is matched, the moderation result will be returned as the corresponding violation tag.
Note:
The pre-defined text library takes effect by account. After you add sample keywords to any pre-defined text library for the same account, these keywords will automatically take effect in all your storage buckets and all moderation policies.
Up to 10,000 sample keywords can be added to a pre-defined text library.
Custom text library: It is the text library you create, where you can add samples of various types of violations. If the text under moderation matches a keyword in the library, it will be marked with the corresponding tag based on the defined library policy.
Note:
The custom text library needs to be associated with a moderation policy and only takes effect within the associated moderation policy.
Up to 2,000 sample keywords can be added to a single custom text library.
