15. A system for automatically generating systematic reviews of received documents in a field of literature, comprising a processor programmed to perform the following steps: constructing associative networks of documents within the received documents; decomposing the associative networks into clusters of topics or fields; performing information extraction within the received documents to provide tagged text; constructing semantic structures of concepts and/or assertions extracted from the tagged text; generating citation-based and content-based summaries of the clusters of topics or fields and the semantic and ontological structures; and generating structured narratives of the clusters of topics or fields and the summaries of the generated semantic structures wherein the programmed processor constructs associative networks of documents within the received documents by selecting node types and link types for each time slice of the received documents, computing similarity or proximity scores for the nodes, constructing matrices of the node information, and merging respective matrices from different time slices.
