Introduction: How we find things. (2/3)

To find material for learning or research we now have:

Digital Libraries

Google

Social MediaOnline Seminars The Web

But can we navigate, instead of randomly hopping and querying?

Introduction: Hold on!

One single integrated tool to solve it all?

No, not exactly…

Hikers Drivers Pilots

Additionaly:We still need to learn how to interpret information

Need good information infrastructure

Conclusions and Future Work

Challenges (Future)Refine detection of common (predefined) objects such as:

Events, People, Locations, Documents...Interface for user to describe and select objects to viewAutomatic grouping of entities and conversion to objectsPathfinding between objects and display of people connected

ConclusionsEnrichment of Social media Data with Linked data:

Useful framework for research and learning environmentsCreation of such an environment:

Done with current state-of-the art technologies Encourages contributions from a supportive communityFacilitates collaboration

Next steps (Near Future)Test, evaluate and implement quality measures.Run information retrieval metrics by simulated scenarios
