The embodiments of the present invention provide a novel way of searching and interacting with content available via a network, such as the Internet, and the World Wide Web. In some embodiments, systems and methods provide a semantically-oriented structure for organizing and accessing content items. The semantic organization can be derived by leveraging user interactions with the content items. The systems and methods leverage the semantics of the content items to help the user find content items that are consistent with the purpose of the user's search. In addition, the embodiments provide a novel navigation paradigm of search results and content items so that the user can more intuitively and more efficiently get information form an information space.
