Outline
• Problems and possible solutions• Introduction to SIOC, SSCF and JeromeDL• Our solution• Conclusions
3
„John’s problems” – motivation scenario
• John - teacher in a distant course• Each lecture assisted with reading material
– Should be distributed week before lecture
• John wants to check if students read and understand• Gathered knowledge passed to the next year’s course.• He wants to utilise the power of Web/Web2.0 - most
materials from:– University library– Wikipedia– Online sources (like blogs)
4
John’s solution
• Decide to use: – Web/Web2.0 potential– Bookmarks sharing tool– Blog platform
5
Is there a better way?
• Solution needs to be interoperable and universal
Social Semantic Information SourcesSocial Semantic Information Sources
6
SIOC – connecting online communities
• Simple but powerful• SIOC ontology – describes
community metadata• Can be used for blogs, wikis and
foras• Allows to:
– Cross-site queries– Topic related searches– Importing data from other sites– ... and many other
7
Sharing knowledge in community with SSCF
• SSCF – Social Semantic Collaborative Filtering• Gathering knowledge as a bookmarks• Bookmarks can be easily shared with friends• Users use friends bookmarks (possible domain expert)• Directories are well (semanticaly) described with
wordNet and taxonomies• Fine grained access rights.
8
Sharing knowledge in community with SSCF
9
SSCF and SIOC
• SSCF supports SIOC data• User can bookmarks blogs
post or even whole blogs• SIOC bookmarks are treated
as standard SSCF resource.
10
JeromeDL – Semantic Digital Library
• SemanticSemantic Digital Library– Digital Library with reach semantic annotations.– Advanced semantic search features.
11
JeromeDL – Social Semantic Digital Library
• SocialSocial Semantic Digital Library• community oriented:
– Enriched with SSCF.• Each user maintains private bookshelf
with bookmarks to bibliographic resources
– Allows to the community to create knowledge (SIOC integration)• Each book becomes a blog entry which can be commented
• Data is exposed in SIOC format.
12
Our solution
• One tool that solves all the John’s problems
13
How it works for John
• Bookmarking interesting content and sharing it with students in right order.
• Students sharing with each other• Students build new knowledge in JeromeDL• All the experience is available for next year students

Ontology mapping
• SIOC with JeromeDL and SSCF:– Support for SIOC
ontology – RDF level.– Ontology alignment
16
Time evaluation
• JeromeDL is much more efficient than 3 separate applications (digital library, blog engine, bookmarks sharing engine)
17
notitio.us
• SSCF is now part of notitio.us – semantic discovery, browsing and sharing– Universal bookmarking system
• Notitio.us is equipped with Informal Knowledge Harvester– Transforms informal knowledge into LOM and other formats.
18
Conclusions
• Social Semantic Information Sources – JeromeDL and SSCF:– Utilise Web 2.0 and Semantic Web potential– Can be very helpful in modern, web oriented e-Learning.
