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
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
10
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
Ontologies in JeromeDL
12
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
13
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
14
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
15
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
