Slide 2: Outline • Problems and possible solutions • Introduction to SIOC, SSCF and JeromeDL • Our solution • Conclusions 2

Slide 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) 3

Slide 4: John’s solution • Decide to use: – Web/Web2.0 potential – Bookmarks sharing tool – Blog platform 4

Slide 5: Is there a better way? Social Semantic Information Sources • Solution needs to be interoperable and universal 5

Slide 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 6

Slide 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. 7

Slide 8: Sharing knowledge in community with SSCF 8

Slide 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. 9

Slide 10: JeromeDL – Semantic Digital Library • Semantic Digital Library – Digital Library with reach semantic annotations. – Advanced semantic search features. 10

Slide 11: JeromeDL – Social Semantic Digital Library • Social 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. 11

Slide 12: Our solution • One tool that solves all the John’s problems 12

Slide 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 13

Slide 14: What is happening SIOC Support for SIOC enabled Exposing book comments information In SIOC SSCF JeromeDL sharing knowledge creating knowledge 14

Slide 15: Ontology mapping • SIOC with JeromeDL and SSCF: – Support for SIOC ontology – RDF level. – Ontology alignment 15

Slide 16: Time evaluation • JeromeDL is much more efficient than 3 separate applications (digital library, blog engine, bookmarks sharing engine) 16

Slide 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. 17

Slide 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. adam.gzella@deri.org 18
