Abstract: Some embodiments of the invention provide a method for tagging and searching for content. In some embodiments, a tagging mechanism is provided that allows the creation of tag chains for tagging content. In some embodiments, once the content is tagged, a search tool is provided that allows the search for content, through the search for tag chains.

Abstract: Some embodiments provide a system that provides a UI for delivering content to a content reviewer. The UI includes (i) a first UI tool for receiving a user query and for searching a set of content items based on the user query, (ii) a second UI tool for retrieving a set of tags associated with each particular content item, and (iii) a third UI tool for generating a list of content items based on the retrieved tags. In some embodiments, each tag in the set of tags is associated with a computed metric. The tags are sorted based on this metric in some embodiments. The metric of some embodiments is based at least partly on a user type. User types include content provider, content retriever, and content evaluator. In some embodiments, the UI also includes a UI tool for receiving content or presenting the list of content items through a communications network. In various embodiments, the communications network may be a network of networks (e.g.

Abstract: Some embodiments provide a system that provides a user interface (UI) for categorizing content. The UI includes (i) a first UI tool for receiving identification of a set of tags and associating the set of tags to the content and (ii) a second UI tool for receiving identifications of relationships between the tags within the set of tags in order to describe the content. In some embodiments, the set of tags includes one or more tag chains that are based on a hierarchy of the tags within the set of tags. In some embodiments, the set of tags includes one or more tag chains that are based on a set of operators. Each operator in the set identifies a relationship between two or more tags within the set of tags. In some embodiments, the UI also includes a UI tool for receiving content or presenting the list of content items through a communications network. In various embodiments, the communications network may be a network of networks (e.g.

Abstract: Some embodiments provide an application for retrieving, tagging, analyzing, and delivering content. The application includes a tag receiver for receiving content from a content provider and for retrieving tags from a tag pool and a tag processor for receiving the content and tags from the tag receiver. The tag processor includes (i) a tag assignor for associating a set of tags to the content and (ii) a tag chain organizer for organizing the set of tags into a tag chain table. The application further includes a tag score calculator for computing a tag score metric for each tag from the set of tags and associating the tag score metric with a particular subset of tags from the set. In some embodiments, the tag processor is further for receiving feedback from a feedback manager. The tag chain table of some embodiments includes a list of tag chains, a user type associated with each tag chain, and an affinity score associated with each user.
