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

):


FOAF and FOAFRealm identity management ontology


Social semantic collaborative filtering (SSCF) ontology


Semantically Interlinked Online Communities (SIOC) ontology


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

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
