This topic provides answers to the frequently asked questions (FAQ) about the moderation effects of the Content Moderation API.

Why is normal content mistaken as abusive content during text moderation? Why does abusive content fail to be detected during text moderation?

Abusive content in text can be classified into Severe Offensive Content, Offensive Content, and Impolite Content based on the abuse severity.

If the abusive content in specific text fails to be detected or the normal content is mistaken as abusive content, we recommend that you create a custom text pattern or term library. Then, specify an ignore list or a review list to ignore or review specific terms.

Why are the terms added to the ignore list still blocked during text moderation?

The terms added to a custom text library may not take effect due to the following reasons:

  • New terms take about 15 minutes to be effective after they are added to a custom text library. We recommend that you try again later.
  • Make sure that the text type and matching method are valid.
    • We recommend that you manage the content that contains less than or equal to five characters as terms and use fuzzy match.
    • We recommend that you manage the content that contains more than five characters as text patterns and use exact match.
  • The custom text library must be applied to the corresponding business scenario before it takes effect.

Why are the images that contain national flags and emblems not blocked during image moderation?

If you want to block images that contain national flags and emblems, select the scenario of Symbolic Content or Event Detection. Then, modify the policy for machine-assisted image moderation for your business scenario in the Content Moderation console. In the scenario of terrorist content detection, the following types of images can be detected: Specified Face, Symbol, Weapons, Event, Religious Content, Uniforms, and Currency. In this case, select The National Flag and Emblem of the People's Republic of China for Symbol. In addition, you must select the detection content for the Symbol parameter in the moderation request.

What do I do if a specific part of a human body in a medical image is detected as pornographic content in Content Moderation?
