Abstract: An interactive advertising service may be provided using a software conversation agent configured to promote products and/or services via a trained classifier and a hierarchy of concepts related to the products and/or services. Upon request, an interactive advertisement is provided for display to a remote user via a third-party content page, the advertisement including a first creative asset and a linguistic communication control. A world state is obtained and updated during a conversational interaction with the remote user. When free-form linguistic input is received from the remote user, the input is classified and the world state updated. When the world state matches a product and/or service, the interactive advertisement is updated to display a second creative asset corresponding to the matching product and/or service.
