Automatically classify your content according to your categories or taxonomy



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.

Rosette out-of-the-box categorization

Rosette is shipped pre-trained to analyze your documents to determine which category in the IAB Tech Lab Content Taxonomy each one belongs to.

While Rosette categorization is configured for the IAB Tech Lab Content Taxonomy out-of-the-box, you can use Rosette for other taxonomies through the classification field training kit made available to users.

Custom training with Rosette

The Rosette Classification Field Training Kit enables users to teach Rosette how to recognize a new taxonomy of categories or classify documents in a language other than English. There are two training methods: (1) keyword-based training uses a set of keywords that are representative of each category (for English only) or (2) machine learning from a training set of documents for the new taxonomy.

The keyword-based training leverages Wikipedia pages that are representative of the keywords to use as the training set. Machine learning on a training set consists of your hand-picked documents that best represent each category. Rosette uses the training documents to machine learn the new taxonomy so that any future documents can be categorized with accuracy.

Categorization is currently only available in English, but using a training set, the classification field training kit teaches Rosette to categorize in any of 30+ languages supported by Rosette Base Linguistics.
