Research Object Model in Sepublica

  1. 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. 2. FROM ELECTRONIC PAPERSTO RESEARCH OBJECTS 11 February 2012 Scientists DICoSE workshop Hypothesis Experiments Annotations Research Object Electronic Results paper Provenance 2 Datasets
  3. 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. 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

  11. 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. 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

  16. 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. 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
