Website and product categorizations
What Is Website Categorization?
Website categorization is a task of classifying website into one of predefined categories, also called taxonomies. Usually this is done by a supervised text classification machine learning model, because in deployment to production one often needs to classify a large number of texts.
Typical website categories
How many categories are in the taxonomy depends on the problem. E.g. in ecommerce setting the top Tier 1 level of categorization usually has 21 categories:
|Apparel & Accessories||226|
|Home & Garden||115|
|Health & Beauty||46|
|Animals & Pet Supplies||25|
|Food, Beverages & Tobacco||13|
|Toys & Games||13|
|Business & Industrial||10|
|Baby & Toddler||6|
|Luggage & Bags||6|
|Arts & Entertainment||4|
|Religious & Ceremonial||3|
|Cameras & Optics||2|
|Vehicles & Parts||1|
Then, on lower Tiers, the google product taxonomy has 190+ categories on Tier 2 and 1000+ categories on Tier 3.
Most usually website categorization is available as API or tool. In this way one can easily integrate it in own products and services.
