In accordance with certain implementations, information is accessed indicating which documents were selected by a user. At least one positive word vector is generated using words contained in at least one of the selected documents, and at least one negative word vector is generated using words contained in at least one of the unselected documents. Document word vectors are generated, and a document rank order is established based on a vector space relationship analysis.

Advertising material may then be selected based on the advertising profile for the user.
