System and method for automatically generating systematic reviews of a scientific field
First Claim
1. A computer-implemented method for automatically generating systematic reviews of documents in a field of literature, comprising a programmed processor performing the following steps:
- constructing associative networks of documents within the received documents;
decomposing the associative networks into clusters of fields or topics;
performing part-of-speech tagging of text within the received documents;
constructing semantic and ontological structures and/or assertions extracted from the documents;
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 field or topic-characterizing documents and the summaries of the generated semantic structures,wherein constructing associative networks of documents within the received documents comprises the processor selecting node types and link types for each time slice of the received documents, computing similarity or proximity scores for the nodes, constructing networks of the node information, and merging respective networks from different time slices.

Abstract
A system and method are provided for automatically generating systematic reviews of received information in a field of science and technology, such as scientific literature, where the systematic review includes a systematic review of a research field in the scientific literature. The method is preferably implemented by a programmed computer and includes the steps of constructing a time series networks of words, passages, documents, and citations and/or co-citations within received information into a synthesized network, decomposing the networks into clusters of fields or topics, performing part-of-speech tagging of text within the received information to provide tagged text, constructing semantic structures of concepts and/or assertions extracted from the source text, generating citation-based and content-based summaries of the clusters of fields or topics and the semantic structures including measuring the saliency, novelty, significance, and transformative features of individual entities in the clusters of fields or topics and semantic structures, and generating structured narratives of the clusters of fields or topics and the summaries of the generated semantic structures, including labeling and summarizing features of the clusters of fields or topics and delinearizing the resulting clusters into templates that provide summarizations of the structure and trends of the information in the clusters at multiple levels of abstraction. Narratives of the citation-based and content-based summaries are merged into a systematic review having a predetermined arrangement.

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. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A computer readable storage medium having instructions stored thereon that when processed by a processor cause the processor to implement a method for automatically generating systematic reviews of documents in a field of literature, wherein the instructions, when executed by the processor, cause the processor to perform the following steps:
-
constructing associative networks of documents within the received documents; decomposing the associative networks into clusters of fields or topics; performing part-of-speech tagging of text within the received documents; constructing semantic and ontological structures of concepts and/or assertions extracted from the documents; 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 field or topic-characterizing documents 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. - View Dependent Claims (30, 31)
