Take-away Home Message
• Different Users → Different
Requirements
• „One size does not fit all” – is that
right?
• JeromeDL – digital library on social
semantic information sources combines the past and the future now!

Presentation Outline
• Motivation: different users, different
requirements
• What is a Semantic Digital Library
• JeromeDL:
– Goals
– Ontologies
– Delivering and utilizing semantic
information
• JeromeDL – short demo
• Conclusions and future work
3
Different User Roles – Different Requirements
Researcher
(publisher)
Goals:
• to publish research results with
least effort required
• to find research results on related
topics
Interested in:
• easy publishing
• citation index
4
Different User Roles – Different Requirements
Average User
(consumer)
Goals:
• to easily find and access knowledge
• to share the knowledge with peers
Interested in:
• efficient search and browsing
techniques
• applications of online communities
5
Different User Roles – Different Requirements
Librarian
(dispatcher)
Goals:
• to preserve knowledge in form of
library resources
• to maintain library resources against
all odds
Interested in:
• precise, formal annotations of
resources
• knowledge organization systems

Digital Libraries
JeromeDL – Social Semantic Digital Library
• Digital Library build with semantics and communities in
mind
• Build to reflect requirements of:
– Librarians
– Researchers
– Average users
• Ultimate goal – accessibility achieved through
– Interface design
– Search and browsing technologies
– In-depth internationalization effort
8
What is a Social Semantic Digital Library?
Social Semantic digital libraries
– integrate information from various
sources
– provide interoperability with other
systems (not only libraries)
– deliver more robust, user friendly
and adaptable search and browsing
interfaces empowered by semantics
and social networking
Ontologies in JeromeDL
• Structure (system administrators):
– JeromeDL structure ontology
• Bibliographic and legacy descriptions (domain experts and
expert users):
– MarcOnt bibliographic ontology
– Extensible MarcOnt suggestions
• Communities (normal users, expert users with restricted
vocabulary):
– FOAF and FOAFRealm identity management ontology
– Social semantic collaborative filtering (SSCF) ontology
– Semantically Interlinked Online Communities (SIOC) ontology
10
Ontologies in JeromeDL
JeromeDL – Delivering Semantic Content
• Providing semantic annotations during uploading
process:
– open module (JOnto) for handling any taxonomies
– keywords based on:
• WordNet
• free tagging
– defining structure of resources in the JeromeDL ontology
• Lifting legacy metadata to MarcOnt ontology
• Community maintained annotations
– social semantic collaborative filtering
– semantic descriptions based on the FOAF metadata
12
JeromeDL – Semantic Information In Use
• Keyword-based search with semantic query expansion
• Semantic search:
– Direct RDF querying
– Natural language templates
• Social Semantic Collaborative Filtering
• Faceted Navigation:
–
–
–
–
creators,
types,
keywords,
topics
• Heterogeneous communication:
– Bibster, A9, OAI
13
JeromeDL - Demo
• Installation
• Key features for a registered user
– Registering
– Browsing (by type, author, keyword, domain),
changing view
– Information in RSS, RDF, and other from MMS
– Expressing semantics (microformats, eRDF, etc.)
– Searching (simple, advanced, distributed, semantic)
• Key features for librarians and administrators
– Uploading, updating, approving and removing
resources
– Reindexing and refreshing
14
Conclusions and Future Work
• “Research stable” version 2.0 of JeromeDL after 2 years of research and development
• JeromeDL realizes the vision of social semantic
information spaces
• Further developed in two streams:
– Industrial stabilization and support by DERI Galway
– More impact on research in key components:
MarcOnt, S3B, HyperCuP and JOnto
