a semantic approach to cross-disciplinary research collaboration
DESCRIPTION
Along with the latest developments in ICT, more specifically Social Media and Web 2.0 tools, there is a tendency towards the use of online services in research and education. This is often referred to as Research 2.0 and Technology Enhanced Learning. Web 2.0 tools are especially useful in cases where experts from different disciplines want to collaborate. There is need for an integrated method that embeds these services in research and learning processes, because it is a laborious task for researchers and learners to check and use all varying types of tools and services. In this paper we explain a flexible model that uses state-of-the-art semantic technologies to model both structured and unstructured research data. The research data is extracted from many online resources and Social Media. We implement learning objects as an abstraction of the semantically modeled research data. We propose an environment that improves the scientific research and learning process by allowing researchers to efficiently browse the information and concepts represented as learning objects.TRANSCRIPT

Introduction: How we find things. (2/3)
To find material for learning or research we now have:
Digital Libraries
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…

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
