Content Taxonomies Dimensions

Content taxonomies dimensions let you understand how your content is categorized across different classification systems. These dimensions cover IAB standardized categories, Google NLP-powered topic detection, and publisher-defined tags, giving you a complete view of your content’s thematic structure.

The content’s IAB Category as defined by the standardized taxonomy created by the Interactive Advertising Bureau (IAB) to classify digital content into specific categories, such as “Technology,” “Health,” or “Sports.”

IAB tier-1 (top level) categories are broad, high-level categories that represent overarching content themes. They give advertisers and publishers a quick way to identify the general type of content for ad targeting and contextual alignment.

IAB tier-2 (sub level) categories are more specific subcategories nested within each top level category, offering detailed classifications of content. This structure allows for more granular targeting, enabling advertisers to align their messaging with niche content and audiences for better relevance and performance.

A topic is a specific, identifiable item within the text of an article that holds distinct meaning or significance and is broadly representative of the article’s theme. Marfeel uses the Google NLP Entity Recognition API to analyze content and identify each article’s topic.

Topics are only available in the following languages:

  • Chinese (traditional)
  • Chinese (simplified)
  • English
  • French
  • German
  • Italian
  • Japanese
  • Korean
  • Portuguese
  • Russian
  • Spanish

The high-level grouping to which a Topic belongs. Topics are groupings of nouns or noun phrases which can be categorized into predefined types, such as New York > Location, Albert Einstein > Person, or Google > Organization. Marfeel uses the Google NLP Entity Recognition API to analyze content and define its topic category.

A high level description of the Topic that is assigned to the content, for example: New York; category: Location > City; Description: city in the United States or Lion; category: Thing > Animal; Description: great cat. Marfeel uses the Google NLP Entity Recognition API to analyze content and define its topic description.

Tags are virtual labels publishers can use to sort and classify articles by subject, theme, or any criteria that matters to them. This makes it easy to organize, search, filter and analyze articles depending on business needs. Visit our documentation to learn how to create tags.

Tag groups are subtopics or subcategories within a broader tag category that add an extra layer of precision and granularity to content categorization. They appear as nested tags, such as contentType:infography or contentType:blogPost. Visit our documentation to learn how tag groups are configured.

For additional content attributes like author, section, and publish date, see the editorial dimensions reference.
