The Website Categorization Service performs classification based on the IAB Content Taxonomy 2.2 (https://iabtechlab.com/standards/content-taxonomy/) and returns multiple categories sorted by their relevance in descending order. 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.
