Our solution

Conclusions

„ 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 - 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

Decide to use:

Web/Web2.0 potential

Bookmarks sharing tool

Blog platform

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

Solution needs to be interoperable and universal

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

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

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 – 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.

Sharing knowledge in community with SSCF

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

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 Semantic Digital Library Digital Library with reach semantic annotations. Advanced semantic search features.

Semantic Digital Library

Digital Library with reach semantic annotations.

Advanced semantic search features.

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.

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.

Our solution One tool that solves all the John’s problems

One tool that solves all the John’s problems

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

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

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

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

SIOC with JeromeDL and SSCF:

Support for SIOC ontology – RDF level.

Ontology alignment

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