Described herein are systems and methods for constructing linear representations of content based networks. The methods comprise receiving a sub-network of a content based network comprising a plurality of fragments connected by one or more links, calculating fragment weight for at least some of the plurality of fragments, calculating link weight for at least one of the one or more links, creating a hierarchical structure from the sub-network, based on at least some of the calculated fragment weights and at least some of the calculated link weights, and converting the hierarchical structure to a linear representation. The linear representation may be augmented by additional overview information such as table of contents and index, which may be automatically generated.
