Automatically sort your content to find exactly the information you need



What is categorization?

Categorization is arranging, or classifying, content sources such as documents and web pages under a list of topics, or taxonomy. Rosette classification automates this process for your content, allowing you to find the documents most relevant to your needs.

Divide and conquer

Organize your content and find the data most relevant to your needs quickly with categorization. Rosette analyzes the text determine which category in the IAB Tech Lab Content Taxonomy it should belong to, and then assigns it accordingly. For example, it separates the “Business” files from the “Sports” articles, and the “Technology & Computing” websites from the “Science” documents.

Adaptable needs

While Rosette categorization is configured for the IAB Tech Lab Content Taxonomy out of the box, you can use Rosette for other taxonomies if you like with on-premise categorization. This requires establishing a training set of documents for the new taxonomy. A training set consists of hand-picked examples that best represent each topic in the taxonomy. Rosette is then trained to the new taxonomy so that any future documents can be categorized with accuracy.

Categorization is currently only available in English, but our on-premise tools can also be custom-trained for new languages as needed.
