SmartProfiles understands meaning


Unlike traditional keyword or entity extraction systems, SmartProfiles creates a human like understanding of the text that goes far beyond just extracting words or entities. SmartProfiles is even able to analyze very short content such as product or video descriptions and respond with a rich and accurate “tree” of metadata.

An example: When analyzing “Keith Richards” a leading competing system is able to detect that “Keith Richards” is a person – category unknown. For the same Leiki SmartProfiles returns a weighted profile of 23 categories, including detailed musical styles and other associations of the person. This yields far better results when finding connections to other relevant items, such as matching products to video clips. In this case Rolling Stones albums (not only albums by Keith Richards) can be targeted alongside Keith Richards video clips. While competing systems struggle Leiki triumphs.

Ideal for Content Targeting and Consumer Analysis


Leiki’s semantic analysis has been created and optimised for more than ten years to not just analyze content, but analyze it in a way that produces the most effective content targeting and consumer analysis. This makes a huge difference in the applicability of the technology.

SmartProfiles is based on the most comprehensive ontology (concept hierarchy) on the market. Leading competing solutions either use no ontologies at all or do searches of standard ontologies available on the web. The problem is that the standard ontologies have not been developed for content or consumer analysis and return categories that produce mismatches and nonsensical results. For example, a standard ontology’s category “famous persons who were born in California” connects people from completely different fields and industries who have nothing to do with each other in reality. Another category “inanimate objects” may sound ok from a philosophical perspective, but in practice under that are everything from a skyscraper to a toothbrush, resulting in a mess.

Unique technology behind SmartProfiles

SmartProfiles are created by Leiki Focus, the world’s most comprehensive general-purpose ontology.

Our standard service can also provide IAB Tier 2 / OpenRTB 2.1-compliant tags. See an example below with both IAB Tier-2 Profile as well as the detailed Leiki High Def Profile. In addition, we support standardized public ontologies and customer-specific taxonomies such as product and content topic categorizations.

Getting Started

Two ways you can send a data feed to us:

Submit content page URLs to our REST API. We will scrape the URL to get the text of the content item and return the profile as an XML response.
If you have access to the full text content (article text without page navigation and other items) you can submit it with the REST API or through a full-text feed. After submitting the content items you can query their profiles with a REST query.
Details are included in the Leiki SmartProfiles API document which we will send upon request. Pricing is based on service level and volume of content. Please contact us for a quote for your application.
