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., the Internet), a private network, a public network, a wireless cellular network, etc.
