The Website Categorization API performs classification based on the IAB Content Taxonomy 2.2.
Initially, IAB taxonomy used up to 4 tiers for some categories. However, the lower-level categories are too narrow, so we combined the lower-level tiers and shrunk the taxonomy to 2 levels for better accuracy and readability. All the original IDs are kept without changes, so you can restore the full path from IAB files if necessary.
Usually, the Website Categorization API returns multiple categories sorted by the relevance in descending order. Without the "minConfidence" parameter, the API returns all the categories having a relevance greater than 0.5. All the results are sorted by their relevance in descending order. The relevance is calculated as the maximum of both tiers' probabilities. For example, if Tier 1's probability is 0.90 and Tier 2's is 0.99, the overall relevance of the set will be 0.99. And vice versa, if Tier 1 is 0.98 and Tier 2's is 0.8, the final probability is 0.98.
