  2. Summary • Introduction • Online Presence ontology • Demo applications • OPOS - Online Presence Ontology Server • Related work - OP4L use case • Conclusions and future work

  3. Introduction • Online presence data: status messages, chat availability, location, etc. • Problems with online presence data • scattered across the Web • not semantically represented • Using online presence data in PLE

  4. Online Presence Ontology • http://online-presence.net/ • jOPO library - Java library for working with OPO data

  5. Demo Applications • Twitter and Spark IM • Enable dynamical extraction of semantically represented online presence data • Possibility of updating user's online presence information

  6. OPOS - Online Presence Ontology Server

  7. Reated Work - OP4L use case • Online Presence integration scenario in a learning setting • awareness of peers' online availability • suggesting who to ask for help • suggesting the best way to contact a peer • Easy to integrate into an existing using OPOS' REST services

  8. Conclusions and Future Work • OPOS could be useful in learning environments • Integrating other social services into OPOS • Providing various statistical analyses and visualizations over the online presence data stored • Deaingl with privacy issues
