Abstract

The contents and topologies of inter-document linkages, such as citations and references among scientific literature, have received increasing research interests in recent years. Some technologies have been fully studied and utilized upon this meaningful information to improve the organization, analysis and evaluation of scientific digital libraries. In this paper, we present a CiteSeer-like system to access scientific papers in computer science discipline by reference linking technique. Moreover, implicit semantics behind reference indices are mined and organized to improve accessibility of scientific papers. In order to model scientific literature and their interlinked relationships, we develop a domain-specific ontology to analyze contents and citation anchor context of scientific papers. Compared with abstract of a specific paper written by authors themselves, we introduce an automatic summary generation algorithm to create objective descriptions from other scholars' perspectives based on the ontology. Semantic queries can also be asked to discover interesting patterns in scientific libraries in order to provide a comprehensive and meaningful guidance for users.
