Knewco is an innovative in-text advertising platform that enables knowledge discovery and sharpens advertising relevancy. Knewco's semantic technology identifies "concepts" in addition to "keywords", and algorithmically associates concepts with other relevant concepts. This innovation makes it possible for users to immediately gain knowledge in an in-text format, for publishers to drive users to relevant areas of their own sites as well as make substantial incremental revenue from new ad inventory, and for advertisers to more effectively reach audiences interested in concepts related to their products and services. Knewco's commercial solution – KnowNow! – represents the latest technological advances in contextual advertising and knowledge discovery. The company is headquartered in suburban Washington, DC with a research team in the Netherlands. For more information visit www.knewco.com.
