Systems and methods are described for the creation of hierarchical networks of overlapping informational Web neighborhoods, where each neighborhood comprises a set of closely linked pages that share a common set of concepts and intent and purpose. A general description of a category of information can be used to generate a network of overlapping communities of web pages and objects, where the neighborhoods represent pages or objects that share a common set of underlying concepts and semantic associations. Each such neighborhood can be semantically tagged. Overlaps among neighborhoods and the hierarchical structure of the network capture complex relationships among the concepts that the corresponding informational neighborhoods represent. All informational neighborhoods of the web can be mapped. The systems and methods can be adapted for any digital content and constitute a hybrid network of contents and their relationships.
