„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)

John’s solution
• Decide to use: – Web/Web2.0 potential– Bookmarks sharing tool– Blog platform
![Page 5: E-Learning on Social Semantic Information Sources](https://reader034.fdocuments.us/reader034/viewer/2022051818/54bfd4114a79596c778b45b1/html5/thumbnails/5.jpg)

Is there a better way?
• Solution needs to be interoperable and universal
Social Semantic Information SourcesSocial Semantic Information Sources

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
![Page 7: E-Learning on Social Semantic Information Sources](https://reader034.fdocuments.us/reader034/viewer/2022051818/54bfd4114a79596c778b45b1/html5/thumbnails/7.jpg)

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.

SSCF and SIOC
• SSCF supports SIOC data• User can bookmarks blogs
post or even whole blogs• SIOC bookmarks are treated
as standard SSCF resource.

JeromeDL – Semantic Digital Library
• SemanticSemantic Digital Library– Digital Library with reach semantic annotations.– Advanced semantic search features.
![Page 11: E-Learning on Social Semantic Information Sources](https://reader034.fdocuments.us/reader034/viewer/2022051818/54bfd4114a79596c778b45b1/html5/thumbnails/11.jpg)

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.

Our solution
• One tool that solves all the John’s problems
![Page 13: E-Learning on Social Semantic Information Sources](https://reader034.fdocuments.us/reader034/viewer/2022051818/54bfd4114a79596c778b45b1/html5/thumbnails/13.jpg)

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
![Page 16: E-Learning on Social Semantic Information Sources](https://reader034.fdocuments.us/reader034/viewer/2022051818/54bfd4114a79596c778b45b1/html5/thumbnails/16.jpg)

Time evaluation
• JeromeDL is much more efficient than 3 separate applications (digital library, blog engine, bookmarks sharing engine)

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.

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.
