Recent works on handling unstructured text employ multilevel filtering techniques for identifying the key terms in documents and then apply mining techniques to extract necessary information. Though these techniques are more efficient in information retrieval, they cannot be applied directly for information extraction, for documents that are more critical in context and also accuracy cannot be expected. Further, loss of hidden and significant information cannot be tolerated in data critical applications emerging based on unstructured documents. Hence, a novel idea of re-organizing the unstructured textual model into feature enriched structured graphical model by adding spatial, logical, lexical, syntactical and semantic features is proposed. The generated graph depicts relationships across the document at all levels from its micro level token to macro level document. Moreover, a structural pattern identification algorithm for generating an XML schema from the generated graph is also recommended. The experimental outcome for a real-time dataset is presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
