  • 1. WORKFLOW-CENTRIC RESEARCH OBJECTS: FIRST CLASS CITIZENS IN SCHOLARLY DISCOURSE Khalid Belhajjame, Oscar Corcho, Daniel Garijo, Jun Zhao, Paolo Missier, David Newman, Raul Palma, Sean Bechhofer, Esteban Garcıa Cuesta, José Manuel Gomez-Perez, Graham Klyne, Kevin Page, Marco Roos, José Enrique Ruiz, Stian Soiland-Reyes, Lourdes Verdes- Montenegro, David De Roure, Carole A. Goblehttp://www.wf4ever-project.org
  • 2. FROM ELECTRONIC PAPERSTO RESEARCH OBJECTS 11 February 2012 Scientists DICoSE workshop Hypothesis Experiments Annotations Research Object Electronic Results paper Provenance 2 Datasets
  • 3. WORKFLOW: EXAMPLE 11 February 2012  Example of a scientific DICoSE workshop workflow that implement a proteomic experiment  The analysis operations that compose the workflow are provided in this case by third party web services. 3
  • 4. BENEFITS OF RESEARCH OBJECTS 11 February 2012  Aresearch object aggregates all elements that are necessary to understand research DICoSE workshop investigations.  Methods (experiments) are viewed as first class citizens  Promote reuse  Enable the verification of reproducibility of the results 4
  • 5. OUTLINE 11 February 2012  Context: Research Objects as First Class Citizens DICoSE workshop  Workflow Research Object Model  LifeCycle of Workflow Research Objects  Conclusions and Future Work 5

  • 11. GROUNDING WORKFLOW-CENTRIC RESEARCHOBJECTS USING SEMANTIC TECHNOLOGIES 11 February 2012  Workflow-centric research objects are encoded using RDF, according to a set of ontologies that are publicly available  Research objects use the Object Exchange and Reuse (ORE) model, to represent aggregation. DICoSE workshop 11
  • 12. GROUNDING WORKFLOW-CENTRIC RESEARCHOBJECTS USING SEMANTIC TECHNOLOGIES 11 February 2012(CONT.)  We use the Annotation Ontology (AO), to annotate research object resources and their relationships. DICoSE workshop 12
  • 13. OUTLINE 11 February 2012  Context: Research Objects as First Class Citizens DICoSE workshop  Workflow Research Object Model  LifeCycle of Workflow Research Objects  Conclusions and Future Work 13

  • 15. OUTLINE 11 February 2012  Context: Research Objects as First Class Citizens DICoSE workshop  Workflow Research Object Model  LifeCycle of Workflow Research Objects  Conclusions and Future Work 15
  • 16. CONCLUSIONS 11 February 2012  ResearchObjects capture information that is necessary for understanding the results of research investigations as well as the methods DICoSE workshop (workflows) used in those investigation  Wepresented a model for specifying workflow research objects  Wespecified how instances of that model can be encoded using semantic web technologies using standards such as Object Exchange and Reuse, and the Annotation Ontology 16
  • 17. ONGOING AND FUTURE WORK 11 February 2012  We are currently developing in the context of the Wf4Ever project a family of tools for the management of workflow research objects DICoSE workshop   Integration with the myExperiment Social Network Portal  We are also investigating issues such as:   Decay   Discovery and Reuse   Scalability 17
  • 18. RESEARCH OBJECT SPECIFICATION AREPUBLICLY AVAILABLE 11 February 2012Wf4Ever Research Object Specification is available DICoSE workshopat http://wf4ever.github.com/ro/Wf4Ever Research Object Vocabularies andOntologies Primer is available athttp://wf4ever.github.com/ro-primer/ 18
