Motivation

From paper books to social media

Semantic services in JeromeDL

Social services in JeromeDL

Metadata in use in JeromeDL

Semantic DL in eLearning and Museums

Conclusions

Social Semantic Information Spaces

Motivation (1) How to integrate and search information from different sources?

How to integrate and search information from different sources?

Motivation (2) How to share and interconnect knowledge in a digital library?

How to share and interconnect knowledge in a digital library?

The old days of paper books Library: Archive (storage space) Bibliographic cards (metadata) Librarian (interface) Pros: Someone to talk to, to explain, to help in searching Library as a meeting place Cons: Based on physical location Libraries are not connected – we have to visit every place

Library:

Archive (storage space)

Bibliographic cards (metadata)

Librarian (interface)

Pros:

Someone to talk to, to explain, to help in searching

Library as a meeting place

Cons:

Based on physical location

Libraries are not connected – we have to visit every place

Yesterday ’s world of digital content Digital library Database and archive (storage) Digital bibliographic descriptions (metadata) Full-text search (interface) Pros: Content accessible online Federations of libraries – visit less places Cons: Lonely user No one to talk to, we need to find the right keywords, what if we do not know them (“man without an ear” paintings example) Still many problems with interconnecting (different) libraries

Digital library

Database and archive (storage)

Digital bibliographic descriptions (metadata)

Full-text search (interface)

Pros:

Content accessible online

Federations of libraries – visit less places

Cons:

Lonely user

No one to talk to, we need to find the right keywords, what if we do not know them (“man without an ear” paintings example)

Still many problems with interconnecting (different) libraries

To morrow of interconnected , social media Semantic Digital Libraries Semantic bibliographic description (interconnected metadata) A nnotations provided by users ( social metadata) Collaborative search and browsing (interface) Features Search and browsing based on semantics empowers users Users contribute to the classification process Users can understand community driven annotations Users enhance digital content using blogs, wikis on the side RDF provides bases for interconnection of digital libraries

Semantic Digital Libraries

Semantic bibliographic description (interconnected metadata)

A nnotations provided by users ( social metadata)

Collaborative search and browsing (interface)

Features

Search and browsing based on semantics empowers users

Users contribute to the classification process

Users can understand community driven annotations

Users enhance digital content using blogs, wikis on the side

RDF provides bases for interconnection of digital libraries

JeromeDL - Introduction Joint effort of DERI , National University of Ireland, Galway and Gdansk University of Technology (GUT) Distributed under BSD Open Source license Digital library build on semantic web technologies to answer requirements from: librarians, scientists and communities .

Distributed under BSD Open Source license

Digital library build on semantic web technologies to answer requirements from: librarians, scientists and communities .

JeromeDL - Properties Support for different kinds of bibliographic medatata, like: DublinCore , BibTeX and MARC21 at the same time. Making use of existing rich sources of bibliographic descriptions (like MARC21) created by human. Supporting users and communities: user s ha ve control over their profile information ; community-aware profiles are integrated with bibliographic descriptions support for community generated knowledge Delivering communication between instances: P2P mode for searching and user authentication Hierarchical mode for browsing

Support for different kinds of bibliographic medatata, like: DublinCore , BibTeX and MARC21 at the same time.

Making use of existing rich sources of bibliographic descriptions (like MARC21) created by human.

Supporting users and communities:

user s ha ve control over their profile information ;

community-aware profiles are integrated with bibliographic descriptions

support for community generated knowledge

Delivering communication between instances:

P2P mode for searching and user authentication

Hierarchical mode for browsing
