Search result ontologies for digital libraries

Abstract

This PhD investigates a novel architecture for digital libraries. This architecture should enable search processes to return instances of result core ontologies further on called result ontologies linked to documents found within a digital library. Such result ontologies would describe a search result more comprehensively, concisely and coherently. Other applications can then access these result ontologies via the web. This outcome should be achieved by introducing a modular ontology repository and an automatic ontology learning methodology for documents stored in a digital library. Current limitations in terms of automatic extraction of ontologies should be overcome with the help of seed ontologies, deep natural language processing techniques and weights applied to newly added concepts. The modular ontology repository will be comprised of a top-level ontology layer, a core ontology layer and a document and result ontology layer. © 2013 Springer-Verlag Berlin Heidelberg.
