Semantic Digital Libraries

Time: Wednesday, May 9 (half-day, afternoon, 1:30pm to 5:00pm)

Location: Coleman

Abstract:

The aim of this tutorial is to educate attendees on the applications of Semantic Web and Social Networking (Web 2.0) technologies in digital library systems. These technologies include metadata management, semantic search and browsing, personalized and community-aware services, and semantically empowered federations of digital libraries. The semantic digital libraries can be used in enterprise scale systems such as knowledge management systems, medical records systems, legal research systems and others will be discussed at some depth. These applications can benefit in manners which directly impact the ROI for the effort of including semantic encoding and metadata into an enterprises digital library based systems and services. After this tutorial, the audience will be able to start using existing semantic digital libraries or apply Semantic Web technologies to digital library systems.

We will start by defining problems in the domain of semantic digital libraries and present solutions that provide building blocks for semantic digital libraries, such as WordNet, DMoz, and SKOS. We will then present the architecture of existing semantic digital libraries, elaborate on resource management, search and browsing features, identity management and communication interfaces. We will discuss in detail the problems and solutions for bibliographic metadata management and interoperability, followed by a presentation of semantic search and browsing solutions, and other personalized and community-aware services. We will discuss the future of federations of digital libraries in the context of the Semantic Web and Web 2.0 Internet.

Finally we will present four initiatives that adhere to the idea of a semantic digital library: SIMILE, Corrib.org (JeromeDL, MarcOnt), BRICK and FEDORA. We will wrap up the whole tutorial by encouraging everyone to take part in the discussion on the future of semantic digital libraries.

The presenters have set up their own Web page with further information about the tutorial.

Prerequisite Knowledge:

An introductory or intermediate level of experience in the presented topics, such as digital libraries, knowledge management, and semantic web. However, we will provide a brief introduction to the most important topics such as the semantic web and digital libraries.

Presenters:

Sebastian Ryszard Kruk obtained in 2003 a masters in Computer Science at the Gdansk University of Technology (GUT), Poland. He is a researcher and project manager in the Digital Enterprise Research Institute (DERI), National University of Ireland, Galway, Ireland and a lecturer affiliated with GUT (since 2002). Together with prof. Henryk Krawczyk (GUT) he came up with an idea of applying semantic web technologies to digital libraries which was first implemented at GUT under the Elvis-DL project. He works on the JeromeDL project, a reference implementation of the semantic digital library, which is being developed under the Corrib.org initiative (DERI-GUT). To improve the quality of Elvis-DL/JeromeDL system he has started MarcOnt Initiative, FOAFRealm, HyperCuP, JOnto and S3B open source projects. He published a number of journal, conference and workshop articles based on the use of semantic digital libraries, knowledge management and identity management. He co-organized an NKOS 2006 Workshop at ECDL2006 (special session on semantic digital libraries). Currently he is a director of the semantic infrastructure group in the e-Learning cluster in DERI Galway.

Stefan Decker obtained in 1995 a masters in Computer Science at the University of Kaiserslautern (awarded with distinction). From 1995 to 1999 he worked towards a Ph.D. degree in Computer Science at the University of Karlsruhe (awarded 2002 with distinction). From 1999-2002 he worked as a Postdoc and Research Associate at the Computer Science Department of Stanford University and established one of the first Semantic Web research groups. From July 2002 to July 2005, he worked as a Computer Scientist and Research Assistant Professor at the Information Sciences Institute of the University of Southern California, USA. Since October 2003 he is involved in setting up a new Research Institute, leading the Semantic Web research group as a Senior Research Fellow and Adjunct Lecturer responsible for 10 group members within the Institute and the National University of Ireland. Since July 2006 Stefan is professor and director of the Digital Enterprise Research Institute, leading a research institute employing 70 people. His current research interests include the Semantic Web, metadata, ontologies and semi-structured data, web services, and applications for Digital Libraries, Knowledge Management, Information Integration and Peer-to-Peer technology. He published around 70 papers as books and journal, book, conference, and workshop contributions. He co-organized around 35 scientific workshops and conferences and has edited several special issues of scientific journals. He was editor-in-chief of Elsevier's Journal of Web Semantics, editoral committee member of the Electronic Transactions on Artificial Intelligence (ETAI) (the Semantic Web), the Journal on Internet Research and the Journal on Web Intelligence and Agent Systems (WIAS) and is recognized as one of the most widely cited Semantic Web scientists. His dissertation work was quoted as one of the inspirations for the DARPA DAML program, which span the Semantic Web effort.

Bernhard Haslhofer received his diploma degree in economics and computer science at the Technical University of Vienna (2003). He is now member of Research Studios Austria - Digital Memory Engineering and a doctoral candidate at the University of Vienna. His research interests include semantic web technologies, ontology-based (meta)data integration, and digital library solutions. Since 2004 he has been working as a key developer in the EU FP6 BRICKS project and is responsible for semantic web related aspects in this project. Previously he has been employed for several years as a teaching assistant at the Technical University of Vienna and the University of Vienna.

Predrag Knežević is a researcher and PhD candidate at Fraunhofer IPSI Institute in Darmstadt, Germany. He holds diploma in computer software and engineering from the School of Electrical Engineering, University of Belgrade. Since 2001, as a member of OASYS and i-Info divisions, he was/is a lead software architect in a few EU and national projects like TeachwareOnDemand, MGN, and BRICKS. Before joining Fraunhofer IPSI, he has spent five years working as system and network engineering at broadcasting company B92, Belgrade. His main interests are: peer-to-peer storages, replication protocols, and decentralized systems.

Sandy Payette leads digital library research and development projects at Cornell University in the Information Science program. She is founder and co-director of the internationally-recognized Fedora Project that deploys open-source repository software for digital libraries, institutional repositories, e-science/e-scholarship, open access publishing, and more. Her research focuses on interoperable digital repositories, semantic technologies for digital libraries, service-oriented scholarly communication, digital preservation, information networks, and automated policy enforcement.

Dean Krafft received his Ph.D. in Computer Science from Cornell University in 1981. He is currently the Director of Information Technology for Computing and Information Science at Cornell University, and he is the Principal Investigator on the NSF-Funded National Science Digital Library Project at Cornell. He led the effort over the past two years to convert the NSDL core infrastructure to a web-services digital object repository architecture based on the Fedora repository middleware. The project's current technical efforts focus on extending open-source collaborative applications to create content and context around the resources of the NSDL, using semantic web technologies to represent the relationships among the underlying objects and to support search and discovery within the library. Krafft has been working on digital libraries since 1992, when he worked on the Dienst and NCSTRL projects. He has been a researcher with NSDL since the program's inception in 2001.
