Next week: my PhD defense (Semantic Digital Libraries )

The day has come to wrap up the research I have been doing for the last couple of years. After closing the write up and submitting my thesis in February this year, my PhD defense is approaching very soon.

Here is some information about it. If you are around Galway next Monday - you are welcome to come and watch my presentation at the open session.

When: May, 18th 2009

Where: Conference Room, DERI, NUI Galway (IDA Business Park, Lower Dangan, Galway, Ireland)

Schedule:

  • 10.00 - 10.30 - Open session

  • 10.30 - 11.30 - Closed session - you & the 3 examiners (fingers crossed!)

  • 11.30 - 12.00 - Closed session - examiners only



Abstract:


Until recently, libraries were the prime source of information for both students and scholars. Now this information is published using online with digital library systems. Current digital libraries have to provide efficient information discovery solutions to adapt to the fast development of new technologies; they also have to cater to the current generation of students. The research on the Semantic Web and online social networks contributes to the digital libraries domain by supporting interoperability with formal semantics, improving interlinking of information and encouraging users to contribute and share knowledge.

Semantic technologies support more flexible information management than that offered by classic digital libraries. Information on library resources can be gathered from heterogeneous sources, including contributions from the communities of library users. These annotations, combined with legacy data, build the foundations for more efficient information discovery in digital libraries.

This thesis reviews architectures, abstract models, metadata standards, and various technologies for building digital library management systems. We derive requirements for advanced digital libraries and propose an architecture model and a set of ontologies for semantic digital libraries. Finally, we present information discovery services using semantic and social technologies, and the prototype implementation of a semantic digital library that fulfills the aforementioned requirements.

Our hypothesis is that semantic and social technologies applied to a digital library management system deliver more efficient information discovery solutions, while the library users become more satisfied and can remember more of the information they have learned when using the library. We present two information discovery services that use semantic and social technologies; we also show a prototype of a semantic digital library. We support our hypothesis by discussing the results of initial evaluations of both services and a comprehensive evaluation of the semantic digital library prototype.

Good luck!
