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
